一般他们的规格标准写成（厚度*宽度*C，C表示长度，由于一般卷起来所以用C表示，如果是矩形钢就会有长度）例如我们所看到的瑞丰带钢2.5*315*C，武钢热卷11.5*1500*C，其中315和1500表示宽度为315mm和1500mm，由此我们认定带钢和热卷的区别在于带钢宽度在1000mm以下，所以能通过规格一眼区分瑞丰的带钢和武钢的热卷，至于为什么有人用带钢有人用热卷，那要看他们厂的轧机能扎什么宽度，由此需求也有所不同。至于楼下提到的Q235是指此钢材能在接受235兆帕的压强之下不变形，用来表示钢材的材质，同理Q195也自然是在195兆帕的压强下不变形。 热轧带钢 2.1 带钢热连轧机的紧凑化布置 　　带钢热连轧机主要有全连续式、半连续式、3/4连续式三种布置形式，它们的区别集中在粗轧区。全连续式带钢热连轧机的主要特点是轧机均为不可逆轧机，带钢在粗轧区轧制时，每架轧机只按板坯的前进方向轧制一道，并且不形成连轧；半连续式带钢热连轧机的主要持点是至少有一架可逆式轧制，带钢在粗轧区内采用可逆式轧制，进行多道次压下，在粗轧机组不形成连轧；3/4连续式带钢热连轧机的主要特点是带钢在粗轧区部分轧机采用可逆式轧制，而在最后的两架粗轧机内形成连轧。　　全连续式带钢热连轧机自动化程度高、产量高，但设备多、投资大，轧制流程长，因此轧件热量损失过多，不利于保温、抢温轧制。特别是在生产过程中，由于每架轧机只轧一道次，使得粗轧机大部分时间处于闲置状态，因此设备利用率过低。为此，广泛采用半连续及3/4连续式带钢热连轧机，节约设备投资，提高粗轧机组的利用率，并缩短轧线长度，减少轧件的热量损失。近年来，由于粗轧机控制水平的提高和轧机结构的改进，轧机牌坊强度增大，轧制速度也相对提高，粗轧机单机架生产能力增大，轧机产量已不受粗轧机产量的制约，因此，半连续式粗轧机发展较快。但由于可逆式轧机操作维修复杂，能耗大，所以对于年产300万t以上规模的带钢厂，3/4连续式带钢热连轧机成为主流。2.2 AWC立辊短行程控制　　板坯在粗轧机组中要经过立辊和水平辊交替轧制，通过立辊的侧压实现宽度控制，但是与轧件中部相比，头尾因没有外端的限制作用，在立轧道次将出现头尾失宽。若不对头尾的失宽现象进行有效的控制，则会对宽度精度和成材率产生不利影响。　　有AWC（宽度自动控制）功能的重型立辊轧机是为了适应连铸和有利热轧带钢板坯热装的发展而产生的现代轧机。这类立辊轧机结构先进，主传动电机功率大，侧压能力大，和在轧制过程中对带坯进行调宽、控宽及头尾形状控制，不仅可以减少连铸板坯的宽度规格，而且有利于实现热轧带钢板坯的热装，提高带坯宽度精度和减少切损。　　按控制方式不同，AWC分为：轧制力反馈控制（RF—AWC）、前馈控制（FF—AWC）和短行程控制（SS—AWC）。　　轧制力反馈控制（RF—AWC）是根据侧压时沿板坯长度方向材料硬度不同，会使立辊轧机产生不同的弹跳量，导致轧制力变化的原理，将测得的轧制力变化，由液压AWC装置快速变更辊缝，从而改变轧制压力，使板坯宽度保持为常数，以便水平轧制后的板坯在长度方向上的宽度均匀。　　前馈控制（FF—AWC）是针对板坯在加热炉内加热受水冷滑道影响而产生温度低于其他部位的水印，立辊侧压后进行水平轧制时，水印处的材料宽度大于其他部分的材料宽展，导致长度方向上产生宽度差，侧压时对水印进行跟踪，预设定液压AWC，在水印处加大侧压量，消除水印处产生的多余的宽展量，使水平轧制后的板坯达到设定的宽度值。　　短行程控制（SS—AWC）是解决板坯侧压量较大时，金属易向中部或两个角部流动，造成板坯头尾失宽的问题。此外，板坯侧压边部凸起，呈两端小、中间大，水平轧制后又加大头尾失宽，通过液压AWC装置对板坯的头尾进行短行程控制，调节其侧压量，使板坯头尾经水平轧制后趋于矩形，从而使整个板坯在长度方向上的宽度均匀，少头尾切损，提高产品收得率。2.3 中间坯保温技术和边部感应加热技术　　粗轧机出口带坯长度可达80～90m，进精轧机轧制过程中，为了减少输送辊道上的温度降，以节约能耗，近年来很多工厂还采用在输送辊道上安置绝热保温罩或补偿加热炉（器）。保温罩内表面附一层吸热温升快、热反射率高的特殊合金层，有效地提高了进入精轧的中间坯温度，从而可降低加热炉出坯温度，提高成材率，节约燃耗。还可提高板带末端温度、减少带钢头尾温差，使板带温度更加均匀，可轧出更宽更薄重量更大及精度性能质量更高的板卷。　　带坯在轧制过程中，边部由于散热较快，其温降大于中部温降，温差大约为100℃。边部温差大，在带钢横截面上晶粒组织不均匀，性能差异大，同时，还将造成轧制中边部裂纹和对轧辊严重的不均匀磨损。因此，在精轧机组前对带坯边部进行加热，将温度补偿到与中部温度一致。一般采用电磁感应加热器，可使带坯边部温度提高30～50℃，使带钢横向温度更加均匀，从而减少带钢边部裂纹，以适应轧制薄规格产品和硅钢、不锈钢、高碳钢等特殊品种的钢。

冷轧板带用途很广，如汽车制造、电气产品、机车车辆、航空、精密仪表、食品罐头等。 　　冷轧薄钢板是普通碳素结构钢冷轧板的简称，也称冷轧板，俗称冷板，有时会被误写成冷扎板。冷板是由普通碳素结构钢热轧钢带，经过进一步冷轧制成厚度小于4mm的钢板。由于在常温下轧制，不产生氧化铁皮，因此，冷板表面质量好，尺寸精度高，再加之退火处理，其机械性能和工艺性能都优于热轧薄钢板，在许多领域里，特别是家电制造领域，已逐渐用它取代热轧薄钢板。 　　适用牌号：Q195、Q215、Q235、Q275；SPCC（日本牌号）；ST12（德国牌号） 　　符号：冷轧板的用途 　　1、Q—普通碳素结构钢屈服点（极限）的代号，它是“屈”的第一个汉语拼音字母的大小写；195、215、235、255、275—分别表示它们屈服点（极限）的数值，单位：兆帕MPa（N/mm2）；由于Q235钢的强度、塑性、韧性和焊接性等综合机械性能在普通碳素结构钢中属最了，能较好地满足一般的使用要求，所以应用范围十分广泛。 　　2、S-钢（Steel）、P-板（Plate）、C-冷轧（cold）、第四位C-普通级（common）。 　　3、ST-钢（Steel）、12-普通级冷轧薄钢板、　 　　标记：尺寸精度—尺寸—钢板品种标准 　　冷轧钢板：钢号—技术条件标准 　　标记示例：B-0.57501500-GB708-88；钢板、标准号Q/BQB402，牌号SPCC，热处理状态退火+平整（S），表央加工状态为麻面D，表面质量为FB级的切边（切边EC，不切边EM）钢板、厚度0.5mm，B级精度，宽度1000mm，A级精度，长度2000mm，A级精度，不平度精度为PF.A，则标记为：钢板ECQ/BQB 402-SPCC-SD-FB/（0.51000A2000A-PF.A）； 　　冷轧钢板：Q225-GB912-89 　　主要产地有：宝钢、鞍钢、本钢、武钢、邯钢、包钢、唐钢、涟钢、济钢等 　　冷轧普通薄钢板 ：由普通碳素结构钢或低合金结构钢冷轧制成。冷轧板表面质量较好。具有良好的冲压性能。对其要求要保证冷弯和杯试验合格，常用于汽车等行业和镀层板的原料。 　　冷轧优质薄钢板：主要包括各种优质钢冷轧薄板，最常用的是碳素结构钢板，尤其是深冲压用冷轧薄钢板，是由低碳优质钢08Al冷轧的薄板，钢板按表面质量分为三组；Ⅰ、Ⅱ、Ⅲ，分别表示特别高级、高级、较高的精整表面,按拉延级别分为ZF、HF、F级（代表用于冲制拉延最复杂、很复杂、复杂的零件）,根据钢板厚度允许偏差，又分为A、B两级精度、广泛用于汽车拖拉机工业。 　　冷轧钢板，表面光洁，加工优良，用于汽车、冰箱、洗衣机等家电，以及产业设备、各种建筑材料。随着经济发展，冷轧钢板已被称为现代社会的必须材料。 冷轧产品的分类： 热轧酸洗、轧硬卷、普通冷轧、镀锌（电镀锌、耐指纹、热镀锌）、镀铝锌、电镀锡、彩涂、电工钢（矽钢片）等。 　　1、热轧酸洗：　　2、轧 硬 卷：在常温下，对热轧酸洗卷进行连续轧制。　　产品特点：因为没有经过退火处理，其硬度很高（HRB大于90），机械加工性能极差，只能进行简单的有方向性的小于90度的折弯加工（垂直于卷取方向）。

冷轧是在室温条件下将钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最小厚度是0.1--8.0MM以下，大部份工厂如保定普瑞钢材冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和 市场 需求而决定。冷轧的优缺点：优点：成型速度快、 产量 高，且不损伤涂层，可以做成多种多样的截面形式，以适应使用条件的需要；冷轧可以使钢材产生很大的塑性变形，从而提高了钢材的屈服点。缺点: 1.虽然成型过程中没有经过热态塑性压缩，但截面内仍然存在残余应力，对钢材整体和局部屈曲的特性必然产生影响；2.冷轧型钢样式一般为开口截面，使得截面的自由扭转刚度较低。在受弯时容易出现扭转，受压时容易出现弯扭屈曲，抗扭性能较差；3.冷轧成型钢壁厚较小，在板件衔接的转角处又没有加厚，承受局部性的集中荷载的能力弱。镀锌是在装有镀件、玻璃球、锌粉、水和促进剂的旋转滚桶内，作为冲击介质的玻璃球随着滚桶转动，与镀件表面发生摩擦和锤击产生机械物理能量，在化学促进剂的作用下，将镀涂的锌粉“冷焊”到镀件表面上，形成光滑、均匀和细致的具有一定厚度的镀层。镀锌分为热镀锌和电镀锌两种。热镀锌也叫热浸镀锌和热浸锌，是一种有效的 金属 防腐方式，主要用于各 行业 的 金属 结构设施上。是将除锈后的钢件浸入500℃左右融化的锌液中，使钢构件表面附着锌层，从而起到防腐的目的。电镀锌，是利用电解设备将管件经过除油、酸洗、后放入成分为锌盐的溶液中，并连接电解设备的负极，在管件的对面放置锌版，连接在电解设备的正极接通电源，利用电流从正极向负极的定向移动就会在管件上沉积一层锌，冷镀管件是先加工后镀锌。

1.国内外普通板坯除鳞发展的趋势 近年来，为满足薄板坯短流程热轧(以下简称CSP)生产线的除鳞要求，美国喷雾系统公司开发了最新一代除鳞喷嘴――Mini型HiScaleJetD41832喷嘴，它具有承受压力高、节水、节能、板坯温降较小等优点。随着CSP生产线的增多，Mini型除鳞喷嘴得到越来越多的关注和发展。 普通板坯热轧(以下简称HSM)为了在竞争日益激烈的钢材市场占据有利位置，国内外的HSM也开始对除鳞系统进行以下方面的改造： 1) 提高高压水除鳞系统的系统压力; 2) 增加除鳞集管的道次，除鳞点增多; 3) 降低喷射高度; 4) 除鳞喷嘴种类增多和小流量喷嘴的使用; 最终目的就是提高打击力、控制板坯温降、降低水的消耗;而Mini型除鳞喷嘴因在CSP生产线的成功应用，成为HSM除鳞系统改造的首选除鳞喷嘴。 2.美国喷雾系统公司的Mini型除鳞喷嘴的特点 国内几乎所有的CSP生产线都采用Mini型除鳞喷嘴，此种喷嘴能较好满足CSP线的除鳞要求;国内的一些HSM生产线在进行除鳞系统改造时，也选用Mini除鳞喷嘴。以下是D41832系列Mini除鳞喷嘴的特点： 1) 内部光滑设计大大降低紊流，打击力比普通除鳞喷嘴提高15-30%; 2) 喷射形状象“刀子“一样，喷射的扇形厚度非常薄，水流密度大; 3) 水量消耗非常少 ; 4) 最高可承受压力 — 400bar; 5) 32mm的小外径， — 喷射高度大大降低，最小可至70mm; 6) 在 80 到 400 bar压力范围内，喷射角度保持不变; 7) 优化的BL碳化钨嵌体使喷嘴使用寿命长，是普通碳化钨的4倍。 3 结束语 美国喷雾系统公司Mini型除鳞喷嘴在实际生产中给客户带来了节水、板坯温降降低、产品表面质量提高等实实在在的好处。可以预测，已在CSP生产线普遍应用的Mini型除鳞喷嘴，也将在HSM生产线上推广。

冷轧：用热轧钢卷为原料，经酸洗去除氧化皮后进行冷连轧，其成品为轧硬卷，由于连续冷变形引起的冷作硬化使轧硬卷的强度、硬度上升、韧塑指标下降，因此冲压性能将恶化，只能用于简单变形的零件。轧硬卷可作为热镀锌厂的原料，因为热镀锌机组均设置有退火线。轧硬卷重一般在6~13.5吨，钢卷在常温下，对热轧酸洗卷进行连续轧制。内径为610mm。产品特点因为没有经过退火处理，其硬度很高（HRB大于90），机械加工性能极差，只能进行简单的有方向性的小于90度的折弯加工（垂直于卷取方向）。简单来说，冷轧，是在热软板扎的基础上加工轧制出来的，一般来讲是热轧→酸洗→冷轧这样的加工过程。冷轧是在常温状态下由热轧板加工而成，虽然在加工过程因为轧制也会使钢板升温，尽管如此还是叫冷轧。由热轧经过连续冷变形而成的冷轧，机械性能比较差，硬度太高，必须经过退火才能恢复其机械性能，没有退火的叫轧硬卷。轧硬卷一般是用来做无需折弯，拉伸的产品，1.0以下厚度轧硬的运气好的两边或者四边折弯。化学成分（Wt%）牌号CSiMnPSCuSPCC0.02～0.08≤0.100.15～0.30≤0.045≤0.050≤0.050Q1950.06～0.12≤0.300.25～0.50≤0.045≤0.050≤0.050Q235-B0.12～0.20≤0.300.30～0.70≤0.045≤0.050≤0.050制作工序冷轧通常采用众轧的方式。冷轧生产的工序一般包括原料准备、酸洗、轧制、脱脂、退火(热处理)、精整等。冷轧以热轧产品为原料，冷轧前原料要先除磷，以保证冷轧产品的表面洁净。轧制是使材料变形的主要工序。脱脂的目的在于去除轧制时附在轧材上的润滑油脂，以免退火时污染钢材表面，对不锈钢也为防止增碳。退火包括中间退火和成品热处理，中间退火是通过再结晶消除冷变形时产生的加工硬化，以恢复材料的塑性及降低金属的变形抗力。成品热处理的目的除了通过再结晶消除硬化外。还在于根据产品的技术要求以获得所需要的组织(如各种织构等)和产品性能(如深冲、电磁性能等)。精整包括检查、剪切、矫直(平整)、打印、分类包装等内容。冷轧产品有很高的包装要求，以防止产品在运输过程中表面被刮伤。除上述工序外在生产一些特殊产品时还有各自的特殊工序。如轧制硅钢板时，在冷轧前要进行脱碳退火，轧后要进行涂膜、高温退火、拉伸矫直(见张力矫直)与回火等。用于冷轧带刚的轧机有二辊轧机、四辊轧机和多辊轧机。应用最多的是四辊轧机。轧制更薄的产品则要采用多辊轧机。多辊轧机的种类很多，如六辊轧机、偏八辊轧机，十二辊轧机，二十辊轧机等(见轧机)。随着对板形要求的提高，发展了许多改进板形的技术，如弯辊技术、窜辊技术和交叉轧辊技术等。冷轧带钢轧机按机架排列可分为单机可逆或不可逆式与多机连续式两类。前者适用于多品种、少批量或合金钢产品比例大的情况。它投资低、建厂快，但产量低，金属消耗较大。多机架连续轧制适合于产品品种较单一或者变动不大的情况，它有生产效率高、产量大的优点，但投资较大。与热轧带钢(见热连轧宽带钢生产工艺、热轧窄带钢生产)相比，冷轧带钢(见冷板扎带生产)的轧制工艺有以下特点：(1)采用工艺润滑和冷却，以降低轧制时的变形抗力和冷却轧辊；(2)采用大张力轧制，以降低变形抗力和保持轧制过程的稳定。采用的平均单位张力值为材料屈服强度的10%～60%，一般不超过50%；(3)采用多轧程轧制。由于冷轧使材料产生加工硬化，当总变形量达到60%～80%时，继续变形就变得很困难。为此要进行中间退火，使材料软化后轧制得以继续进行。为了得到要求的薄带钢，这样的中间退火可能要进行多次。两次中间退火之间的轧制称为一个轧程。冷轧带钢的退火在有保护气体的连续式退火炉或罩式退火炉中进行(见冷轧板带退火)。冷轧带钢的最小厚度目前可达到0.05mm，冷轧箔材可达到0.001mm。

冷轧钢板就是经过冷轧生产的钢板，俗称冷板。　　冷轧是在室温条件下将No.1钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下，如大部份工厂冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。 　　一般来说，冷轧钢板分为三代产品：沸腾钢为第一代，铝镇静钢为第二代，无间隙原子刚（IF钢）为第三代。   您查询的关键词是：冷轧钢板  。如果打开速度慢，可以尝试快速版；如果想保存快照，可以添加到搜藏。 "冷轧钢板""2,冷轧钢板(YB459-64)""厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)",,"厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)""0.4","600x1200 700x1430 800x1500 1000x2000","3.56",,"2.5","6000x1200 7000x1430 800x1500 1000x2000","22.25""0.45",,"4.01",,"2.75",,"24.48""0.5",,"4.45",,"3.0",,"26.70""0.6",,"5.34",,"3.5",,"31.50""0.7",,"6.23",,"4.0",,"35.60""0.8",,"7.12",,"4.5",,"40.05""0.9",,"8.01",,"5.0",,"44.50""1.0",,"8.90",,"5.5",,"48.95""1.1",,"9.79",,"6.0",,"53.40""1.2",,"10.68",,"6.5",,"57.85""1.35",,"12.02",,"7.0",,"62.30""1.5",,"13.35",,"7.5",,"66.75""1.65",,"14.60",,"8.0",,"71.20""1.8",,"16.02",,"9.0",,"80.10""2.0",,"17.80",,"10.0",,"89.00""2.25",,"20.03""冷轧铜条""2,冷轧铜条(YB459-64)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)""0.20","200~400","500~800","1.78",,"2.50","200~500","500~2000","22.25""0.25",,,"2.23",,"2.75",,,"24.48""0.30",,,"2.67",,"3.00",,"1000~2000","26.70""0.35",,,"3.12",,"3.50",,,"31.15""0.40","200~500","500~2000","3.56",,"4.00",,,"35.60""0.45",,,"4.01",,"4.50",,,"40.05""0.50",,,"4.45",,"5.00",,,"44.50""0.60",,,"5.34",,"5.50",,,"48.95""0.70",,,"6.23",,"6.00",,,"53.40""0.80",,,"7.12",,"6.50",,,"57.85""0.90",,,"8.01",,"7.00",,,"62.30""1.00",,,"8.90",,"8.00",,,"71.20""1.20",,,"10.68",,"9.00",,,"80.10""1.30",,,"11.57",,"10.00",,,"89.00""1.40",,,"12.46",,"11.00",,,"97.90""1.50",,,"13.35",,"12.00",,,"106.8""1.60",,,"14.69",,"13.00",,,"115.7""1.80",,,"16.02",,"14.00",,,"124.6""2.00",,,"17.80",,"15.00",,,"133.5""注 铜板和条(热轧,冷轧)的制造牌号为T2,T3,T4和TU和TUP,其化学成分应符合YB145-71规定""特殊用冷轧黄铜条""3,特殊用冷轧黄铜条(YB555-65)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)""0.20","200~300","500~1000","1.76",,"1.6","200~500","500~2000","14.08""0.25",,,"2.20",,"1.8",,,"15.84""0.30","200~400",,"2.64",,"2.0",,,"17.60""0.35",,,"3.08",,"2.5",,,"22.00""0.40","200~500",,"3.52",,"2.75",,,"24.20""0.45",,,"3.96",,"3.0",,,"26.40""0.50",,"500~2000","4.40",,"3.5",,,"30.80""0.55",,,"4.84",,"4.0",,,"35.20""0.60",,,"5.28",,"4.5",,,"39.60""0.70",,,"6.16",,"5.0",,,"44.00""0.80",,,"7.04",,"5.5",,,"48.40""0.90",,,"7.92",,"6.0",,,"52.80""1.0",,,"8.8",,"6.5",,,"57.20""1.2",,,"10.56",,"7.0",,,"61.60""1.3",,,"11.44",,"8.0",,,"70.40""1.4",,,"12.32",,"9.0",,,"79.20""1.5",,,"13.20",,"10.0",,,"88.00""注 (1)标记举例:用H80制成的,厚度为0.8mm,宽度为300mm,长度为1000mm的1/2硬条标记为:"" 条H80-Y20.8x300x1000YB555-65.""

热镀锌带钢，采用热浸锌工艺技术镀锌，提高带钢的耐腐蚀性能。带钢是各类轧钢企业为了适应不同工业部门工业化生产各类 金属 或机械产品的需要而生产的一种窄而长的钢板。带钢又称钢带，是宽度在1300mm以内，长度根据每卷的大小略有不同。带钢一般成卷供应，具有尺寸精度高、表面质量好、便于加工、节省材料等优点。同钢板相同，带钢按所用材质分为普通带钢和优质带钢两类；按加工方法分热轧带钢、冷轧带钢两种。带钢广泛用于生产焊接钢管，作冷弯型钢的坯料，制造自行车车架、轮圈、卡箍、垫圈、弹簧片、锯条、五金制品和刀片等。冷轧带钢生产工艺流程一般为：酸洗→轧制→工艺润滑→退火→平整→剪切→包装。热轧带钢介绍1．产品：普通碳素结构钢钢带标准：（GB/T3524-1992 、GB/T8164-1993、QJ/HG02.22-1995规格：厚度：2.0-5.0mm 宽度： 100-230mm钢种：HG5 、Q215、 Q2352．产品：优质碳素结构钢钢带标准：（GB8749-1998 、GB/T8164-1993 size="3">）规格：厚度：2.5-4.5mm 宽度： 钢种：10# 、20#、 45#、50# 、40Mn、 45Mn、65Mn3．产品：自行车链条用钢带标准：QJ/HG02.15-1991规格：厚度：2.75-4.5mm 宽度：125-205mm钢种：ZL20MnSi用途：焊接管用、工业链条用、自行车变速链条用、建筑机械、工具用、弹簧用 （卷帘门弹簧、卡簧等）现在钢材 市场 的带钢 价格 在不断上涨，有些型号的带钢还处于缺货状态。如天津钢材 市场 

冷轧：用热轧钢卷为原料，经酸洗去除氧化皮后进行冷连轧，其成品为轧硬卷，由于连续冷变形引起的冷作硬化使轧硬卷的强度、硬度上升、韧塑指标下降，因此冲压性能将恶化，只能用于简单变形的零件。轧硬卷可作为热镀锌厂的原料，因为热镀锌机组均设置有退火线。轧硬卷重一般在20-40吨，钢卷在常温下，对热轧酸洗卷进行连续轧制。内径为610mm。　　　　产品特点：因为没有经过退火处理，其硬度很高（HRB大于90），机械加工性能极差，只能进行简单的有方向性的小于90度的折弯加工（垂直于卷取方向）。　　　　简单来说，冷轧，是在热轧板卷的基础上加工轧制出来的，一般来讲是热轧---酸洗---冷轧这样的加工过程。　　　　冷轧是在常温状态下由热轧板加工而成，虽然在加工过程因为轧制也会使钢板升温，尽管如此还是叫冷轧。由于热轧经过连续冷变型而成的冷轧，在机械性能比较差，硬度太高。必须经过退火才能恢复其机械性能，没有退火的叫轧硬卷。轧硬卷一般是用来做无需折弯，拉伸的产品，1.0以下厚度轧硬的运气好的两边或者四边折弯。　　　　冷轧一般都会经过退火处理。

冷轧薄钢板，简称冷轧钢板、冷轧薄板、冷轧板、冷板等。它还包括不锈钢板、弹簧钢板、硬钢片、镀锌板、镀锡板、镀铝板等。冷轧薄钢带，简称冷轧钢带、冷轧带钢、钢带、带钢、薄钢带、冷轧卷等。还包括不锈钢带、镀锌钢带、镀锡钢带等。 冷轧钢板标准 冷轧薄钢板、钢带（以下简称冷轧薄板）主要用于零件的冲压加工，而冷轧薄板的力学性能十分重要，它直接关系到板材的冲压性能。冷轧薄板是以不同的热处理状态分级的，不同硬度的材料，用于不同的加工方法，国家标准GB/T 13237-1991《优质碳素结构钢冷轧薄钢板和钢带》将冷轧薄板大致分为三级，P级用于普通冲压，S级用于深度冲压，Z级用于最深度冲压。中国冶金标准YB/T 5059-1993《低碳钢冷轧钢带》将薄钢板按硬度分为五级，即：TR（特级）、R（软）、BR（半软）、DY（低硬）和Y（冷硬）。其实通过一定的冷轧变形程度和冷轧后热处理的恰当配合，可以在广泛的范围内满足用户关于材料力学性能方面的要求。冷轧薄板根据用户加工上的要求可以分成更多的级别。例如：日本工业标准JIS G3141-1996《冷轧碳素钢钢板和钢带》的分类除分为一般用（spcc）、冲压用(spcd)和深冲压用（spce）三类外，还细分为退火、标准调质、1/8硬、1/4硬、1/2硬、全硬等级别。 在冷轧薄板力学性能的检测方面，一些标准只规定了拉伸试验，另一些标准除拉伸试验外还规定了硬度试验。 中国标准GB/T 13237-1991就只规定了拉伸试验，技术要求冷轧钢板标准如表一所示：牌号 抗拉强度/MPa伸长率不小于拉延级别Z－S和PZSP08F275～365275～38034323008,08Al,10F275～390275～41032302810295～410295～43030392815F315～430315～45029282715335～450335～47027262520355～490335～50026252425——390～540——242330——440～590——222135——490～635——201940——510～650————1845——530～680————1650——540～715————14 日本标准JIS G3141-1996《冷轧碳素钢钢板和钢带》（该标准中包含了冷轧薄钢板和钢带）规定了拉伸试验，也规定了硬度试验，该标准的力学性能要求如下：表二：标准调质和退火的钢板、钢带的拉伸试验质牌号抗拉强度/MPa 不小于 伸长率/%不小于试样按以下公称厚度/mm>=0.250.250.400.601.01.6>=2.5SPCC SPCD SPCE(270) 270 270(32) 34 36(34) 36 3836 38 40　 37 39 41 　　 (38) 40 42 　39 41 435号试样轧制方向 表三：标准调质和退火的钢板、钢带的硬度值。调质区分符号 硬度最大HRBHV退火A57105标准调质S65115 注：厚度小于0.6mm的钢板和钢带，原则上不进行拉伸试验。 表四：1/8硬、1/4硬、1/2硬和全硬材料的拉伸试验值。调质区分 符号 抗拉强度/MPa伸长率/%最小试样1/8硬8294～410255号试样轧制方向1/4硬4370～490101/2硬2440～590——硬1>=550——     表五：1/8硬、1/4硬、1/2硬和全硬状态的硬度值。调质区分符号HRBHV1/8硬 1/4硬8450～7165～8095～130 115～1501/2硬 硬2174～89 ≥85135～185 ≥170注：HRB和HV，仅选用其中之一。英国标准BS 1449/1.9-1991《厚板、薄板和钢带第一部分：碳素钢和碳锰钢厚板、薄板和钢带具有成形性能的冷轧窄钢带技术条件》对冷轧板分级为CS1（铝镇静稳定化超深冲）、CS2（超深冲）、CS3（深冲）、CS4（折边）、CS15（商品级）。这项标准的力学性能要求如表六所示： 表六：钢材交货时的力学性能轧制状态和级别退火（A）或平整冷轧（SP）状态硬度HV1)2)最大屈服强度Re1)/MPa最小抗拉强度Rm1)/MPa最小伸长率A1)/%最小弯心直径1)（180°弯曲）原始标距LO50mm80mmCS1A9514027038（36）0aSP10514027036（34）0aCS2A9514027036（34）0a SP10014027036（34）0aCS3A100（140）（280）（34）（32）0aSP110（140）（280）（34）（32）0aCS4A105（140）（280）——0aSP115（140）（280）——0a 注：1）窄钢带交货应符合，或者硬度和弯曲试验，或者拉伸和弯曲试验，但硬度和拉伸试验不应同时进行。     2）对于SP（平整冷轧）状态，与镀层精整（PL）或镜面光洁度（MF），或以“无拉伸痕”交货的钢材组合，最大硬度可以提高5个HV或抗拉强度可以提高20MPa。     3）牌号CS2、CS3和CS4的硬度值仅适用于沸腾钢。 如上所述冷轧薄板的力学性能可以通过拉伸试验来检测，也可以通过硬度试验来检测。由于硬度试验设备简单、易于掌握，试验效率高，并且金属硬度与强度之间有一定的对应关系，所以硬度检测是确定材料力学性能的更方便的方法。冷轧薄板的硬度检测可以用于冷轧板生产过程的质量控制，更适于生产冲压产品的厂家对原材料进行力学性能的复检。 日本工业标准JIS G3141-1996规定的硬度试验是洛氏硬度HRB和维氏硬度HV。维氏硬度试验可用于冷轧薄板，但洛氏硬度HRB却不适用于测试薄板材料。因为当板材厚度小于2mm时，测试HRB硬度可能会因为发生“测砧效应”而使测量的硬度值失准。对于薄板材料，可以测试表面洛氏硬度HRN或HRT，然后换算成HRB或HV硬度。冷轧钢板标准生产了一种便携式表面洛氏硬度计，它非常适合测试薄板和钢带材料，它可以在生产现场、销售现场或材料仓库快速进行冷轧薄板材料的洛氏硬度检测，完成一次测量仅需要10秒钟时间，检测的板材厚度范围为0.05-50mm。这种仪器可以用在冷轧薄板带的生产线上，对产品的热处理效果进行在线的质量控制。这种仪器更适用于冲压产品的生产厂家。可以用它对购入的板材硬度进行复检，可以携带它去钢材市场选购材料，也可以利用它对自己厂生产的冲压产品进行硬度检测。 这种仪器如果配上一个支承座，还可以放到办公桌上使用。可以对成批的成品或半成品工件做逐件检测。它的测试精度与台式洛氏硬度计相同。 目前冷轧薄带材料正在向超薄方向发展，据报道，上海宝钢已扎制出厚度为0.08mm的冷轧薄板带材。采用本所生产的PHR-1S型表面洛氏硬度计，配一个金刚点砧座，就可测试薄至0.05mm冷轧薄板带材料的硬度。 这种应用完全可以取代维氏硬度计，使冷轧薄板材料的力学性能检测实现快速、简便、经济。

冷轧镀锌板，是一种镀锌钢板。钢板按轧制分为热轧和冷轧两种。冷轧板是平板状的，矩形的，可直接轧制而成的。冷轧是在室温条件下将钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最小厚度是0.1--8.0MM以下，大部份工厂如保定普瑞钢材冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和 市场 需求而决定。冷轧和热轧的区别： 1、冷轧成型钢允许截面出现局部屈曲，从而可以充分利用杆件屈曲后的承载力；而热轧型钢不允许截面发生局部屈曲。2、热轧型钢和冷轧型钢残余应力产生的原因不同，所以截面上的分布也有很大差异。冷弯薄壁型钢截面上的残余应力分布是弯曲型的，而热扎型钢或焊接型钢截面上残余应力分布是薄膜型。3、热轧型钢的自由扭转刚度比冷轧型钢高，所以热轧型钢的抗扭性能要优于冷轧型钢。冷轧的优缺点：优点：成型速度快、 产量 高，且不损伤涂层，可以做成多种多样的截面形式，以适应使用条件的需要；冷轧可以使钢材产生很大的塑性变形，从而提高了钢材的屈服点。缺点: 1.虽然成型过程中没有经过热态塑性压缩，但截面内仍然存在残余应力，对钢材整体和局部屈曲的特性必然产生影响；2.冷轧型钢样式一般为开口截面，使得截面的自由扭转刚度较低。在受弯时容易出现扭转，受压时容易出现弯扭屈曲，抗扭性能较差；3.冷轧成型钢壁厚较小，在板件衔接的转角处又没有加厚，承受局部性的集中荷载的能力弱。冷轧镀锌板用于汽车、冰箱、洗衣机等家电，以及 产业 设备、各种建筑材料。

3月29日消息：世界各国钢铁产业政策日益体现出环境友好、节能减排、安全可靠、持续技术创新的主旋律,以应对过去资源过度消耗与环境恶化对社会可持续发展的压力、以及用户对钢铁产品在品种、规格、质量、性能上不断提高的需求,同时在面对铝、镁、工程塑料等材料竞争中保持自身的主体地位。对于钢铁产品,主要体现在新型高强度、超高强韧、高延展性、轻质钢铁材料的开发与应用推广上。高锰钢广泛用作冲击摩擦磨损工件已有百年历史,但板带作为工程结构用钢近10年来才逐断走向深入和明朗化,现已引起业界的广泛关注。经适当成分设计与制造流程,高锰板带钢表现出优异的强度、塑性、加工硬化性、以及抗冲击安全性,在高速列车、汽车、高架建筑等领域展示出诱人的应用潜力。根据变形机制差异,高锰钢可分为TRIP(相变诱导塑性)钢、TWIP(孪晶诱导塑性)钢、SIP(剪切带诱导塑性)钢,一定成分的高锰钢可能存在多种变形方式,并且形变机理对变形温度敏感。同时,该钢特定的合金元素组成以及中高温力学性能特点,对冶炼、铸造、轧制等流程提出了一系列新的技术问题。　　本文从高锰板带钢的成分体系与性能、制造技术等两方面综述了国内外的进展情况,特别分析了高锰板带钢制造技术难点,以及薄板坯连铸连轧、薄带连铸连轧等近终形制造技术在高锰钢制造中的应用,并据此浅析了国内高锰板带钢的研发思路。　　结论　　(1)高锰板带钢成分体系多,具有优异的强度、塑性、加工硬化性能、抗冲击安全性,近10年来成钢厂、高校、科研机构研发的热点,在高速列车、汽车、高架建筑等领域中的应用前景逐渐明朗,正处于商业化应用前期。　　(2)ArcelorMittal公司已利用热轧工艺制造出合格的汽车产品(电镀锌)并投放市场,TyhssenKrupp公司利用带式薄带连铸连轧制造出强塑性理想的高锰钢带钢,POSCO掌握了一套改善高锰钢原形薄带表面质量的方法,萨尔茨吉特计划2009年底实现高锰钢的薄带连铸生产。　　(3)中国高锰板带钢研发整体水平与国外存在差距,同时受到国外逐渐增强的知识产权制约。应尽快根据市场应用潜力确定重点开发高锰钢体系、结合制造流程特点设计高锰钢成分,自主开发出高锰板带钢制造产业化成套技术,缩小差距、突破技术瓶颈并争取在局部领域引领今后的发展方向。  (miki)

冷轧钢板就是经过冷轧生产的钢板。冷轧是在室温条件下将No.1钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，冷轧钢板的密度不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下，如大部份工厂冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。冷轧钢板的密度：热轧钢板含碳量可比冷轧钢板略高些。在成份相持不大的情况下密度是一样的。但如果成份相差悬殊，如不锈钢不论冷轧、热轧密度都在7.9g/cm3左右。具体还要看成份，热轧只是延展性更好，钢材同样受到压力作用

冷轧板卷是以热轧卷为原料，在室温下在再结晶温度以下进行轧制而成，包括板和卷，国内众多钢厂如宝钢、武钢、鞍钢等均可以生产。其中成张交货的称为钢板，也称盒板或平板；长度很长、成卷交货的称为钢带，也称卷板。 生产过程中由于不进行加热，所以不存在热轧常出现的麻点和氧化铁皮等缺陷，表面质量好、光洁度高。而且冷轧产品的尺寸精度高，产品的性能和组织能满足一些特殊的使用要求，如电磁性能、深冲性能等。  　　规格：厚度为0.2-4mm，宽度为600-2 000mm，钢板长度为1 200-6 000mm。  　　牌号：Q195A-Q235A、Q195AF-Q235AF、Q295A(B)-Q345 A(B)；SPCC、SPCD、SPCE、ST12-15;DC01-06  　　性能：主要采用低碳钢牌号，要求具有良好的冷弯和焊接性能，以及一定的冲压性能。 钢号规格（厚*宽*长）冷轧板规格板0.4*1000*C0.5*1250*C0.35*1000*C 1.0*1000*C0.7*1020*C0.3*1000*C 0.4*1000*C1.5*1000*C2.5*1000*C 2.5*1000*C2.0*1250*C1.5*1250*C 1.0*1250*C1.0*1000*C1.0*1000*2000 1.2*1000*20001.5*1000*20000.5*1000*C 2.0*1000*20003.0*1000*20001.0*1250*2000 1.0*1250*25001.2*1250*20001.2*1250*2500 1.5*1250*20001.5*1250*20002.0*1250*2000 2.0*1250*25002.5*1250*20002.5*1250*2500 3.0*1250*20003.0*1250*25001.0*1250*2500 0.35*1000*20000.4*1000*20000.45*1000*2000 0.5*1000*20000.6*1000*20000.7*1000*2000 0.8*1000*20002.0*1000*20001.2*1000*2000 1.5*1000*20001.0*1250*2000

（二）电工用冷轧硅钢薄板（GB2521-88）  　　用含硅0.8％-4.8％的电工硅钢为材质，经冷轧而成。  　　冷轧硅钢片分晶粒无取向和晶粒取向两种钢带。冷轧电工钢带具有表面平整、厚度均匀、叠装系数高、冲片性好等特点，且比热轧电工钢带磁感高、铁损低。用冷带代替热轧带制造电机或变压器，其重量和体积可减少0％-25％。若用冷轧取向带，性能更佳，用它代替热轧带或低档次冷轧带，可减少变压器电能消耗量45％-50％，且变压器工作性能更可靠。  　　用于制造电机和变压器。通常，晶粒无取向冷轧带用作电机或焊接变压器等的状态；晶粒取向冷轧带用作电源变压器、脉冲变压器和磁放大器等的铁芯。  　　钢板规格尺寸：厚度为0.35、0.50、0.65mm，宽度为800-1000mm，长度为≤2.0m。

下面是关于求购镀锌带钢的相关信息：镀锌带钢，是带钢经过镀锌工艺而成的成品。镀锌工艺分为热镀锌和电镀锌两种。带钢是各类轧钢企业为了适应不同工业部门工业化生产各类 金属 或机械产品的需要而生产的一种窄而长的钢板。带钢又称钢带，是宽度在1300mm以内，长度根据每卷的大小略有不同。带钢一般成卷供应，具有尺寸精度高、表面质量好、便于加工、节省材料等优点。同钢板相同，带钢按所用材质分为普通带钢和优质带钢两类；按加工方法分热轧带钢、冷轧带钢两种。带钢广泛用于生产焊接钢管，作冷弯型钢的坯料，制造自行车车架、轮圈、卡箍、垫圈、弹簧片、锯条、五金制品和刀片等。冷轧带钢生产工艺流程一般为：酸洗→轧制→工艺润滑→退火→平整→剪切→包装。热轧带钢介绍1．产品：普通碳素结构钢钢带标准：（GB/T3524-1992 、GB/T8164-1993、QJ/HG02.22-1995规格：厚度：2.0-5.0mm 宽度： 100-230mm钢种：HG5 、Q215、 Q2352．产品：优质碳素结构钢钢带标准：（GB8749-1998 、GB/T8164-1993 size="3">）规格：厚度：2.5-4.5mm 宽度： 钢种：10# 、20#、 45#、50# 、40Mn、 45Mn、65Mn3．产品：自行车链条用钢带标准：QJ/HG02.15-1991规格：厚度：2.75-4.5mm 宽度：125-205mm钢种：ZL20MnSi用途：焊接管用、工业链条用、自行车变速链条用、建筑机械、工具用、弹簧用 （卷帘门弹簧、卡簧等）在求购镀锌带钢时，要注意他的镀锌方式，一般情况热镀锌带钢使用的较多，而电镀锌带钢因其镀层薄，且不环保，已被禁止使用。

自从电磁带钢稳定技术应用到商业领域，这一技术很快就被广泛应用到热浸镀锌生产线上。经镀锌槽的带钢通过气刀时更加平稳，能够保证涂层重量偏差处于更窄的允许范围之内，进而可减少锌的消耗量。 　　以往的镀锌过程中，当带钢经过气刀时会发生细微振动，产生弯曲，造成涂层表面不够平整。为了保证整条带钢的镀层重量都能达到规定要求，通常会需要略微过量的锌。例如，为了达到100g/m2的要求，将会使用105～110 g/m2的锌。 　　这一技术通过布置一组3～5个电磁感应线圈进行工作，线圈的多少由线圈宽度决定，线圈位置紧靠气刀的上方，与带钢交叉布置。线圈与带钢之间的距离使用感应器不间断测量，并依据理论距离对线圈进行调整。线圈发出的磁力将自动调节，使带钢尽可能平整，同时实现带钢的振动和弯曲最小化。 　　德国EMG自动化设备公司表示，采用带钢稳定技术后，在满足100g/m2的标准规格时，一般单面能减少使用2g/m2的锌，并且节约量还能提高到5～6 g/m2。此外，这一技术还将减少气刀的空气或氮气用量，使气刀更靠近带钢，从而减轻带钢振动。www.metal114.cn 　　带钢稳定技术最初是30年前由英国钢铁公司最先研发，经过长时间的发展后，现在采用这一技术的工业设备不止一种。由西马克德马格公司与西马克Elotherm公司、Fontaine 工程公司共同研发的带钢稳定系统，2007年4月首次安装在韩国现代制钢公司的镀锌生产线。同时，俄罗斯马格尼托哥尔斯克钢铁公司也采购了两套。 　　EMG自动化设备公司将自己开发的电磁感应带钢稳定系统命名为eMASS，并与蒂森克虏伯钢铁公司合作进行改进，于2007年8月安装在蒂森克虏伯钢铁公司位于杜伊斯堡的1号连续镀锌生产线上。与此同时，另一套系统已经交付中国宝钢使用。到目前为止，EMG自动化设备公司已交付的或者已预定的电磁感应带钢稳定系统达到了17套。其中6套供应安赛乐米塔尔公司位于美国哥伦布、比利时Eurogal、法国Florange、西班牙Aviles、美国克里夫兰和比利时Gent的钢厂；另5套已经或者即将安装在韩国，东部制钢公司1套、现代制钢公司2套、联合制钢公司2套。最新的订单来自于康力斯集团Myriad子公司位于法国的镀锌彩涂生产线。EMG自动化设备公司表示，与Danieli Kohler紧密合作，将电磁感应带钢稳定系统与后者的气刀完美结合。该公司还透露，带钢稳定技术还将应用到镀铝板生产线上。 　　瑞典ABB与SSAB钢板公司合作开发EM稳定装置。该装置是由频率转换器控制的3对水冷电磁铁组成，适用于宽度2100mm带钢。为了保证高质量的薄涂层，振动控制显得愈发重要。

锌是一种重要的有色金属，是铜合金的一个极关键的合金元素，没有锌就没有黄铜；锌的另一些重要用途是作为带钢的热浸镀（hot dip galvanizing）层与制造干电池等。镀锌钢板不但具有强的抗腐蚀性能，而且具有更好的表面处理性能与冲压性能，在工业生产中获得更加广泛的应用。  　　研究与实用证明，无论从抗腐蚀性能还是其他使用性能方面来看，在薄钢板或带钢上镀锌-铝合金比镀纯锌要好得多。因此，自上世纪80年代以来，锌-铝合金镀层获得了越来越广泛的应用。  　　热浸镀锌-铝合金时的合金可在钢铁公司的浸锌厂配制，也可在铝厂配制好，生产出锌-铝铸锭，钢厂将这种锭熔化后即成为浸镀熔体。过去浸镀熔体都由钢厂自行配制，目前则有由铝厂配制与生产锌-铝合金锭的趋势，而且后者占的比例会越来越多。  　　由铝厂生产锌-铝合金（Zincalum）锭有诸多优点：可节约能源；成分稳定。例如生产AlZn45合金锭，可节约熔化铝的一部分能源，因为铝厂生产这种热浸镀锌-铝合金用的是从电解槽中吸出的原铝，温度为950℃左右，注入混合保温炉后，仍具有850℃以上温度，而锌的熔点只有419.5℃。将一定量的锌加入保温炉，会很快熔化，而不需要加热，就可以形成锌-铝合金熔体。  　　AlZn45合金及其他热浸镀锌-铝合金的熔点都在450℃以下，熔化它们比钢厂自行配制锌-铝合金熔体的能耗当然会有所降低。另外，铝厂生产锌-铝合金是大规模生产，合金成分稳定，能确保品质。铝厂生产的热浸镀锌-铝合金锭可以是20Kg左右的小锭块，而可以是质量达1t左右的大锭。大锭的烧损比小锭的低一些，所以最好用大锭。 .

每天都在炼钢的你，对超薄带钢的了解，有多少? 每一天，人类都在追求极致，摸着一手生产出的带钢，你身体内的洪荒之力有没有时刻提醒你，要生产出更薄更好带钢产品? 小编精心整理了目前国际上最先进的热轧超薄带钢无头轧制技术资料，你还不赶紧来充电? 废话不多说，干货来了，快接招! 我国薄板坯连铸连轧技术的发展历程 从技术特点和工业化应用来讲，中国薄板坯连铸连轧发展的过程可以划分成4个阶段。 第一个阶段：1984年—1999年，引入期。 在1975—1985年间科技部确定了薄板坯连铸连轧的技术研究工作，开启了中国薄板坯连铸的发展历程。 广州珠江钢厂投入使用国内第一条CSP产线;珠江钢厂、包钢、邯钢引进了德国的西马克技术，在当时钢铁工业快速发展的过程当中，对钢铁大量需求的情况下，薄板坯连铸连轧可以发挥一定作用。 第二阶段：2002—2008年，建设了9个薄板坯连铸连轧项目，包括了26个连铸机，单线产量300万t。 第三阶段：2008年之后，稳定发展期。这一时期，薄板坯连铸连轧的基础配置基本上确定下来，主要装备也基本稳定，其中，中国对高品质特殊钢、硅钢进行了相关的研究，并在一定程度上实现了产业化。 第四阶段：目前关于无头轧制ESP产线和ESP技术的研究和投入使用。 日照钢铁控股集团有限公司，国内第一家引进普锐特冶金技术有限公司ESP无头连铸连轧带钢工艺生产线的公司，首单ESP产品在2015年5月上市并交付用户，其ESP无头轧制生产线，设计钢种包括低碳钢、中碳钢、IF钢、HSLA、DP双相钢，部分产品的规格如下所示：工艺流程 传统的板带热连轧精轧机组生产均以单块中间坯进行轧制，因此，不可避免地要经过进精轧机组时的穿带、加速轧制、减速轧制、抛钢、甩尾等一系列过程，由此发生的尺寸公差和力学性能的不均匀性，很难在原有工艺框架内得到解决。热轧带无头轧制新技术正是解决这些问题的一项重要的技术突破。 目前，热带无头轧制技术有两种： 一是在常规热连轧线上，在粗轧与精轧之间将粗轧后的高温中间带坯在数秒钟之内快速连接起来，在精轧过程中实现无头轧制; 二是无头连铸连轧技术(ESP技术)。ESP技术可以看做是当前薄板坯连铸连轧技术不断发展升级而产生的无头轧制中最具有代表性的前沿技术。 接下来，讲解无头连铸连轧技术(ESP技术)的工艺流程。 1 连铸机浇注前的准备 修砌好并在干燥站干燥完毕的中间罐用吊车运至浇注平台上的中间罐车上，再用平台上的烘烤站将中间罐烘烤到1100℃，浸入式水口烘烤到约1250℃。 接通结晶器冷却水、二冷水、压缩空气、设备冷却水、液压、润滑等系统，使其处于正常状态。 引锭杆送至结晶器内合适位置，并将引锭头在结晶器内塞紧，并填好冷却用废钢屑。2 连铸机浇注操作 经由钢包进入中间罐的钢水，当其液面高度达到一定高度时，打开塞棒，此时钢水通过浸入式水口注入结晶器。 当钢液在结晶器内上升到规定的拉坯位置时，启动操作箱上“浇注”按钮，扇形段驱动辊按预定的起步拉速开始拉坯。与此同时，结晶器振动装置、二冷喷淋水、二冷室排蒸汽风机同时启动。 结晶器内己凝固成坯壳带液芯的铸坯由引锭杆牵引离开结晶器下口，经足辊、弯曲段、弧形段往下移动，此时冷却水和被压缩空气雾化的冷却水直接喷到铸坯上进行冷却。弧形的铸坯进入矫直段被矫直，然后进入水平段。 铸坯出水平段和粗轧机后，经摆动剪剪切，铸坯与引锭杆脱离，引锭杆快速送至引锭杆存放装置处。与引锭杆分离后的连铸坯送至后部的轧钢车间。 3 连续轧制过程 无头轧制模式 铸坯经过大压下轧机轧制成厚度为8mm-20mm的无头中间坯。该无头中间坯通过带保温罩的辊道运送至感应加热炉，感应加热炉以高效、准确、动态在线和灵活的方式将无头中间坯加热至要求的约1200℃。感应加热炉后设置有夹送辊除鳞箱。无头中间坯经过除鳞后进入架精轧机组，轧制成目标厚度的带钢。带钢经过输出辊道和层流冷却后得到理想的微观组织结构。在输出辊道的末端、卷取机之前，高速飞剪将无头带钢进行分卷，然后在地下卷取机上进行卷取。半无头轧制模式 对于厚度超过1mm的热轧带钢，则用摆式剪或者转縠飞剪将把中间坯按生产单个钢卷的尺寸进行切分，由此ESP生产线进入半无头轧制模式。切分后的中间坯将加速前行，以便和下一块中间坯的头部稍拉开一些距离。切分成单卷规格的中间坯经过感应加热炉加热、除鳞并穿带进入精轧机组轧制至成品规格、然后再经层流冷却即可获得微观结构均匀和机加工性能良好的带钢，最后由地下卷取机卷成钢卷。 目前流行的其他无头轧制技术 1.常规热连轧线上的无头轧制技术 现有常规热连轧线上，在粗轧与精轧之间将粗轧后的中间带坯在数秒钟之内快速连接起来，在精轧连轧机组实现无头轧制，经层流冷却线后的飞剪切断，由卷取机卷成热卷。2.JFE与新日铁热带无头轧制技术 日本JFE公司千叶厂于1996年开发成功采用感应焊接作为粗轧后的中间带坯连接方式，该方式要求对带坯接头区进行快速加热，形成热熔区实现对焊连接。该无头轧制生产线投产后，在提高热轧板带生产效率和成材率及板形板厚精度、降低轧辊消耗、扩大薄宽规格品种等方面取得了显著的效果，在国际冶金行业产生重大影响。3.浦项制铁热带无头轧制技术 韩国浦项制铁和三菱—日立公司于2007年初联合开发成功热轧中间带坯的无头轧制技术，即利用切头飞剪完成带坯瞬间的固态连接。对于薄板坯连铸连轧的发展方向 一是发挥薄板坯连铸连轧流程本身的特点，以实现连续化生产。 研究显示，对于单坯轧制，随着厚度的减薄，生产的事故率陡然增加，但无头轧制就不存在这样的问题。特别是极薄规格和宽规格产品，传统流程几乎没有办法生产。 而如果采用薄板坯连铸连轧，连铸出来的坯子本来就是一个完整的坯，所以，薄板坯连铸连轧在连续化生产方面有得天独厚的条件。这就是ESP技术在世界范围得到广泛应用的原因。 因此，今后薄板坯连铸连轧发展的一个方向，应该是连续化生产，也就是无头轧制。当然，实现无头轧制的工艺配置和技术有多种，如何更好地实现还在探讨中。 二是充分发挥薄板坯连铸连轧的特点，开发有竞争力的产品。 薄板坯连铸连轧快速凝固的特点使得产品的偏析更少、铸态组织更均匀，这样的优势对于成分更加复杂的特殊钢产品生产是非常有利的。 目前，中国在高品质特殊钢、高强钢、硅钢、薄规格产品方面已经开发出系列产品，并进入了市场。但是，未来还有很多工作要做，如高牌号硅钢。

稀土用途    稀土的用途十分广泛。只要在一些传统产品中加入适量的稀土，就会产生许多神奇的效果。目前，稀土已广泛应用于冶金、石油、化工、轻纺、医药、农业等数十个 行业 。稀土钢能显著提高钢的耐磨性、耐磨蚀性和韧性；稀土铝盘条在缩小铝线细度的同时可提高强度和导电率；将稀土农药喷洒在果树上，即能消灭病虫害，又能提高挂果率；稀土复合肥即能改善土壤结构，又能提高农产品 产量 ；稀土元素还能抑制癌细胞的扩散。       由于稀土元素在光、磁、电领域能够产生特殊的能量转换、传输、存储功能，因而，通过对稀土原料的加工，已形成稀土永磁材料、稀土发光材料、稀土激光材料、稀土贮氢材料、稀土光纤材料、稀土磁光存储材料、稀土超导材料、稀土原子能材料等一批新型功能材料。这些材料因为无污染、高性能而被称为“绿色材料”，它们已经或将要在电子信息、汽车尾气净化、电动汽车以及空间、海洋、生物技术、生理医疗等领域发挥巨大的作用。       稀土有净化环境的功能。汽车尾气净化催化剂是稀土应用量最大的项目之一。电子信息 产业 的发展给稀土在高新技术领域应用带来高潮。由于稀土元素具有特殊的电子层结构，可以将吸收到的能量转换为光的形式发出。利用这一特性制成的稀土荧光材料可用于计算机显示器及各种显示屏和荧光灯。以彩电为代表的家电产品广泛应用了稀土的荧光、抛光、永磁、功能陶瓷、玻璃添加剂等多种功能材料，带动了80年代稀土开发应用；90年代以来，以计算机为代表的电子信息产品飞速发展，这些产品除用上述稀土材料外，还有稀土贮氢、磁光、超磁致伸缩等功能材料，直接拉动了世界稀土生产的增长。       以稀土制造的永磁材料，磁性能高出普通永磁材料4到10倍，尤其钕铁硼永磁体是目前发现磁性能最高的永磁材料，被称为超级磁体和当代永磁之王。由于此类材料具有超乎寻常的功能，使电子信息设备在不断提高性能的同时，也实现了轻、薄、小型化。稀土永磁材料还在各类电机、核磁共振仪器、磁悬浮列车等领域有着精妙的应用，并被确定为电动汽车主发动机的首选材料。有专家 预测 ，未来几年内，如果稀土永磁材料得到良好的应用，仅材料产值就将达35亿美元，其辐射产值将达到数千亿美元。       稀土贮氢材料贮存密度大于液氢，体积却只有普通钢瓶的六分之一。目前应用最为成功的是镍氢电池，  其等体积充电容量是目前广泛使用的镍镉电池的2倍，且没有记忆效应和镉的污染；与锂离子电池相比，又具备价低、安全性能好的优势，被各国科技和 产业 界称为“绿色电池”，已大量应用于便携式电器、移动电话等无线电子设备，并可望成为下世纪电动汽车的电源。     稀土用途愈来愈广泛，稀土也将会在更多的场合被使用。     以上是稀土用途介绍,更多信息请详见上海 有色金属 网。

铝锭用途相关知识很多，让我们对它进行下介绍。铝锭用途:　　近五十年来，铝已成为世界上最为广泛应用的金属之一。特别是近年来，铝作为节能、降耗的环保材料，无论应用范围还是用量都在进一步扩大。尤其是在建筑业、交通运输业和包装业，这三大行业的铝消费一般占当年铝总消费量的60%左右。　　在建筑业上，由于铝在空气中的稳定性和阳极处理后的极佳外观，使铝在建筑业上被越来越多地广泛应用，特别是在铝合金门窗、铝塑管、装饰板、铝板幕墙等方面的应用。　　在交通运输业上，为减轻交通工具自身的重量，减少废气排放对环境的污染，摩托车、各类汽车、火车、地铁、飞机、船只等交通运输工具开始大量采用铝及铝合金作为构件和装饰件。随着铝合金加工材的硬度和强度不断提高，航空航天领域使用的比例开始逐年增加。　　在包装业上，各类软包装用铝箔、全铝易拉罐、各类瓶盖及易拉盖、药用包装等用铝范围也在扩大。　　在其它消费领域，电子电气、家用电器（冰箱、空调）、日用五金等方面的使用量和使用前景越来越广阔。  铝锭分类铝锭按成分不同分重熔用铝锭、高纯铝锭和铝合金锭三种：按形状和尺寸又可分为条锭、圆锭、板锭、T形锭等几种，下面是几种常见的铝锭； 　　重熔用铝锭--15kg，20kg（≤99．80％Al）： 　　T形铝锭--500kg，1000kg（≤99．80％Al）： 　　高纯铝锭--l0kg，15kg（99．90％～99．999％Al）； 　　铝合金锭--10kg，15kg（Al--Si，Al--Cu，Al--Mg）； 　　板锭--500～1000kg（制板用）； 　　圆 锭--30～60kg（拉丝用）。在我们日常工业上的原料叫铝锭，按国家标准（GB/T 1196-2008）应叫“重熔用铝锭”，不过大家叫惯了“铝锭”。它是用氧化铝-冰晶石通过电解法生产出来的。铝锭进入工业应用之后有两大类：铸造铝合金和变形铝合金。铸造铝及铝合金是以铸造方法生产铝的铸件；变形铝及铝合金是以压力加工方法生产铝的加工产品：板、带、箔、管、棒、型、线和锻件。按照?重熔用铝锭?国家标准，“重熔用铝锭按化学成分分为6个牌号，分别是Al99.85、Al99.80、Al99.70、Al99.60、Al99.50、Al99.00”（注：Al之后的数字是铝含量）。目前，有人叫的“A00”铝，实际上是含铝为99.7%纯度的铝，在伦敦市场上叫“标准铝”。大家都知道，我国在五十年代技术标准都来自前苏联，“A00”是苏联国家标准中的俄文牌号，“A”是俄文字母，而不是英文“A”字，也不是汉语拼音字母的“A”。和国际接轨的话，称“标准铝”更为确切。标准铝就是含99.7%铝的铝锭，在伦敦市场上注册的就是它。通过了解铝锭用途的知识，我们才可以掌握其真正的价值，你可以登陆上海有色网查找更多的信息。

锌锭用途主要有以下几个方面;(一)制造铜合金材(如黄铜);用于汽车制造和机械行业。锌具有适用的机械性能。锌本身的强度和硬度不高，但加入铝、铜等合金元素后，其强度和硬度均大为提高，尤其是锌铜钛合金的出现，其综合机械性能已接近或达到铝合金、黄铜、灰铸铁的水平，其抗蠕变性能也大幅度被提高。因此，锌铜钛合金目前已被广泛应用于小五金生产中。 (二) 用于铸造锌合金;主要为压铸件，用于汽车、轻工等行业。许多锌合金的加工性能都比较优良，道次加工率可达60%-80%。中压性能优越，可进行深拉延，并具有自润滑性，延长了模具寿命，可用钎焊或电阻焊或电弧焊(需在氦气中)进行焊接，表面可进行电镀、涂漆处理，切削加工性能良好。在一定条件下具有优越的超塑性能。三)镀锌;锌具有优良的抗大气腐蚀性能，所以被主要用于钢材和钢结构件的表面镀层(如镀锌板)，广泛用于汽车、建筑、船舶、轻工等行业。近年来西方国家开始尝试直接用锌合金板做屋顶覆盖材料，其使用年限可长达120-140年，而且可回收再用，而用镀锌铁板作屋顶材料的使用寿命一般为5-10年.以上是笔者为您提供的有关锌锭用途的咨询, 

现如今黄铜在人们的日常生活中和工业上产中应用的已经越来越广泛了，但是很多人对于黄铜的用途还只是停留在黄铜工艺品、铜器、化工原料等简单的理解上。到底黄铜用途是什么？了解黄铜用途，才能更好的利用黄铜。    黄铜是由铜和锌所组成的合金。如果只是由铜、锌组成的黄铜就叫作普通黄铜。黄铜常被用于制造阀门、水管、空调内外机连接管和散热器等。    黄铜用途概述：黄铜以锌作主要添加元素的铜合金﹐具有美观的黄色﹐统称黄铜。铜锌二元合金称普通黄铜或称简单黄铜。三元以上  的黄铜称特殊黄铜或称复杂黄铜。含锌低於36％的黄铜合金具有良好的冷加工性能﹐如含锌30％的黄铜常用来制作弹壳﹐俗称弹壳黄铜或七三黄铜。含锌在36～42％之间的黄铜合金由和固溶体组成﹐其中最常用的是含锌40％的六四黄铜。为了改善普通黄铜的性能﹐常添加其他元素﹐如铝﹑镍﹑锰﹑锡﹑硅﹑铅等。铝能提高黄铜的强度﹑硬度和耐蚀性﹐但使塑性降低﹐适合作海轮冷凝管及其他耐蚀零件。锡能提高黄铜的强度和对海水的耐腐性﹐故称海军黄铜﹐用作船舶热工设备和螺旋桨等。铅能改善黄铜的切削性能﹔这种易切削黄铜常用作钟表零件。黄铜铸件常用来制作阀门和管道配件等。   更多特殊黄铜用途：    铅黄铜用途：铅实际不溶于黄铜内，呈游离质点状态分布在晶界上。铅黄铜按其组织有α和（α+β）两种。α铅黄铜由于铅的有害作用较大，高温塑性很低，故只能进行冷变形或热挤压。（α+β）铅黄铜在高温下具有较好的塑性，可进行锻造。    锡黄铜用途：黄铜中加入锡，可明显提高合金的耐热性，特别是提高抗海水腐蚀的能力，故锡黄铜有“海军黄铜”之称。    锰黄铜用途：锰在固态黄铜中有较大的溶解度。黄铜中加入1%～4%的锰，可显著提高合金的强度和耐蚀性，而不降低其塑性。    铁黄铜用途：铁黄铜中，铁以富铁相的微粒析出，作为晶核而细化晶粒，并能阻止再结晶晶粒长大，从而提高合金的机械性能和工艺性能。铁黄铜中的铁含量通常在1.5%以下，其组织为（α+β），具有高的强度和韧性，高温下塑性很好，冷态下也可变形。常用的牌号为Hfe59-1-1。    镍黄铜用途：镍与铜能形成连续固溶体，显著扩大α相区。黄铜中加入镍可显著提高黄铜在大气和海水中的耐蚀性。镍还能提高黄铜的再结晶温度，促使形成更细的晶粒。    更多关于黄铜用途的资讯，请登录上海 有色 网查询。

澳大利亚研制出铝冷轧机板型控制新技术澳大利亚工业自动化服务公司日前开发研制出铝冷轧机板型控制新技术，采用铝板带边部热喷淋技术来控制板型，并已成功应用于美国纳西州诺兰达公司的六重铝冷轧机改造。据了解，该技术的铝板带边部热喷淋控制系统由计算机控制软件和边部热喷淋系统组成，在铝板带两边的每一边按装有两个热喷淋装置，每个装置上的喷咀控制范围为25mm区段，由几个喷咀组成一个整体，在轧机工作时实施边部热喷淋，从而决了铝板带边部紧的板型缺陷，提高了轧制速度，增加了每个道次的金属通过量。

钨条用途非常广泛。钨金原名钨 金属 条，简称钨金、钨条。 钨金是世界上少有的一种 有色 矿产品，年 产量 很低，用途非常广泛，主要用于铸造配料用原料。钨金来源于一种白色砂型矿体，矿线特别微小，经过采掘、研磨、水重选、提炼等多道工艺，得到品位达到95%以上的钨矿粉，再经过高温电炉提炼成型生产出的成品才是钨金。钨金的熔点：3500℃。目前钨矿主要分布在中国和俄罗斯，中国现在是世界上最大的钨金出口国。钨条的主要用途包括：钢铁工业： 　　钨大部分用于生产特种钢。广泛采用的高速钢含有9%——24%的钨、3.8%——4.6%的铬、1%——5%的钒、4%——7%钴、0.7%——1.5%碳。高速钢的特点是在空气中有高的强化回火温度（700——800℃）下，能自动淬火，因此，直到600—650℃它还保持高的硬度和耐磨性。合金工具钢中的钨钢含有0.8%——1.2%的钨；铬钨硅钢含有2%——2.7%的钨；铬钨钢中含有2%——9%的钨；铬钨锰钢中含有0.5%——1.6%的钨。含钨的钢用于制造各种工具：如钻头、铣刀、拉丝模、阴模和阳模，气支工具等零件。钨磁钢是含有5.2%——6.2%的钨、0.68%——0.78%碳、0.3%——0.5%铬的永磁体钢。钨钴磁钢含有11.5%——14.5%的钨、5.5%——6.5%钼、11.5%——12.5%钴的硬磁材料。它们具有高的磁化强度和矫顽磁力。 　　碳化钨基硬质合金： 　　钨的碳化物具有高的硬度、耐磨性和难熔性。这些合金含有85%——95%的碳化钨和5%——14%的钴，钴是作为粘结剂 金属 ，它使合金具有必要的强度。主要用于加工钢的某些合金中，还含有钛、钽和铌的碳化物。所有这些合金都是用粉末冶金法制造的。当加热到1000——1100℃时，它们仍具有高的硬度和耐磨性。硬质合金刀具的切削速度远远地超过了最好的工具钢刀具的切削速度。硬质合金主要用于切削工具、矿山工具和拉丝模等。 　　热强和耐磨合金： 　　作为最难熔的 金属 钨是许多热强合金的成分，如3%——15%的钨、25%——35%的铬、45%——65%的钴、0.5%——0.75%的碳组成的合金，主要用于强烈耐磨的零件，例如航空发动机的活门、压模热切刀的工作部件、涡轮机叶轮、挖掘设备、犁头的表面涂层。 　　在航空火箭技术中，以及要求机器零件，发动机和一些仪器的高热强度的其它部门中，钨和其它给熔 金属 （如钽、铌、钼、铼）的合金用作热强材料。 　　触头材料和高比重合金： 　　用粉末冶金方法制造的钨-铜合金（10%——40%的铜）和钨-银合金，兼有铜和银的良好的导电性、导热性和钨的耐磨性。因此，它成为制造闸刀开关、断路器、点焊电极等的工作部件非常的效的触头材料。成分为90%——95%的钨、1%——6%的镍、1%——4%的铜的高比重合金，以及用铁代铜（—5%）的合金，用于制造陀螺仪的转子、飞机、控制舵的平衡锤、放射性同位素的放射护罩和料筐等。 　　电真空照明材料： 　　钨以钨丝、钨带和各种锻造元件用于电子管生产、无线电电子学和X射线技术中。钨是白织灯丝和螺旋丝的最好材料。高的工作温度（2200——2500℃）保证高的发光效率，而小的蒸发速度保证丝的寿命长。钨丝用于制造电子振荡管的直热阴极和栅极，高压整流器的阴极和和各种电子仪器中旁热阴极加热器。用钨做X光管和气体放电管的对阴极和阴极，以及无线电设备的触头和原子氢焊枪电极。钨丝和钨棒作为高温炉（3000℃）的加热器。钨加热器在氢气气体、惰性气体或真空中工作。 　　钨的化合物： 　　钨酸钠用于生产某些类型的漆和颜料，以及纺织工业中用于布疋加重和与硫酸铵和磷酸铵混合来制造耐火布疋和防水布疋。还用于 金属 钨、钨酸及钨酸盐的制造以及染料、颜料、油墨、电镀等方面。也用作催化剂等。钨酸在纺织工业中是媒染剂与染料和在化学工业中用作制取高辛烷汽油的催化剂。二硫化钨在有机合成中，如在合成汽油的制取中用作固体的润滑剂和催化剂。处理钨矿石的时候可得到得三氧化钨，再用氢还原三氧化钨制得钨粉，广泛用于钨材及钨冶金材原料。我国是产钨大国，钨资源储量520万吨，为国外30个产钨国家总储量（130万吨）的3倍多， 产量 及出口量均居世界第一。湖南、江西、河南三省的钨资源储量居全国的前三位，其中湖南、江西两省的钨资源储量占全国的55．48％。湖南以白钨为主，江西以黑钨为主，其黑钨资源占全国黑钨资源总量的42．40％。我国的钨矿大体上分布于我国南岭山地两侧的广东东部沿海一带，尤其是以江西的南部为最多，储量约占全世界的二分之一以上。此外，江西的大余、湖南的汝城、安化、临武、资兴、荼陵等地；以及广西和云南、四川、福建等省也有钨矿资源。国外钨矿的主要产地是加拿大和美国。钨条用途还有很大拓展空间。

锇的用处 锇及其合金在石油化学工业上首要作催化剂。在电子电器工业上，作电阻、继电器、火花塞电极、电触头、热电偶及印刷电路等。在玻璃工业上，锇不会使熔化的玻璃污染，可作为制作光学玻璃时的容器内衬。锇铱合金可以作挂钟和仪器中的轴承，制作笔尖和唱针。 锇的性质 锇是铂族金属之一，呈灰兰色。熔点高，约为3050℃。密度大，为22.5克/厘米3。锇即便在高温下也不易加工，一般只用作合金元素。锇的抗氧化性很差，在空气中，室温下锇表面就生成兰色二氧化锇薄膜。硝酸与锇效果也会生成。此两种氧化物都是挥发性的有毒化合物，能影响粘损害皮肤，自然界中，锇与铂族金属常共生在一起。  .
