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.""

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。

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。

热轧钢材是经过高温加热轧制而成的钢材，它的强度不是很高，但足以满足我们的使用，它的塑性、可焊性较好，因此我们比较常用；冷轧钢是普通热轧钢经过强力拉拔超过应变硬化阶段的钢材，它的强度很高，但韧性、可焊性差，比较硬、脆！    热轧低碳钢 Q/BQB 302 SPHCSPHDSPHE JIS G3131 SPHCSPHDSPHE 适用于制造冷成型加工的零件。  StW22StW23StW24 DIN 1614(EN10111) StW22 (DD11)STW23 (DD12)StW24 (DD13)  一般结构用钢 Q/BQB 303 SS 330SS 400SS 490SS 540 JIS G3101 SS 330SS 400SS 490SS 540 用于建筑、桥梁、船舶、车辆等一般结构件。  St 33St 37-2St 37-3St 44-2St 50-2St 52-3 DIN 17100(EN10025) St 33 (S185)St 37-2 (S235JR)St 37-3 (S235JO)St 44-2 (S275JR)St 50-2 (E295)St 52-3 (S355JO)  焊接结构用钢 Q/BQB 303 SM 400ASM400BSM 400CSM 490ASM490BSM 490CSM490YASM490YBSM520BSM 520C JIS G3106 SM 400ASM400BSM 400CSM 490ASM490BSM 490CSM490YASM490YBSM520BSM 520C 用于建筑、桥梁、船舶、车辆、石油罐、工程机械等要求焊接性能优良的结构件。  B520JJ --- --- 混凝土搅拌车筒体用热连轧钢板。  Welten590RE NSC Welten590RE 可焊高强度钢板，用于压力容器、油罐、工程机械、采矿机械、压力水管等。  B590GJAB590GJB --- ---  机械结构用钢 Q/BQB 303 C 22C35S 20CS 35C DIN 17200JIS G4501 C 22C35S 20CS 35C 用于经切削等加工并热处理后使用的机械结构件。  细晶粒结构钢 --- StE255StE355 DIN 17102 StE255StE355 适用于焊接的细晶粒结构钢。  钢管用钢带钢 Q/BQB 303 SPHT1SPHT2SPHT3 JIS G3132 SPHT1SPHT2SPHT3 用于焊接钢管。  汽车结构用钢 Q/BQB 310BZJ 311BZJ 312BZJ 313BZJ 314 SAPH 310SAPH 370SAPH 400SAPH 440 JIS G3113 SAPH 310SAPH 370SAPH 400SAPH 440 用于要求成形性加工性能的汽车构架、车轮等汽车结构件。  QStE 340TMQStE 380TMQStE 420TMQStE 460TMQStE 500TM SEW 092(EN10149-2) QStE 340TM (---)QStE 380TM (---)QStE 420TM (S420MC)QStE 460TM (S460MC)QStE 500TM (S500MC) 冷变形用热轧粒钢，用于要求良好冷成型性能并有较高或高强度要求的汽车大梁等结构件。  B330CLB380CLB420CL --- --- 有良好冷成型性能，用于汽车滚型车轮轮网及轮幅。  B440QZRB480QZR --- --- 制造汽车传动轴管用。  B 320L B 550LB 510L B 420LB 510DL --- --- 汽车大梁、横梁用。  锅炉及压力容器用钢 Q/BQB 320 HII19Mn6 DIN 17155 (EN10028-2) HII (P265GH)19Mn6 (P355GH) 除保证常温性能外，还保证较高温度下的力学性能，适用于蒸汽锅炉设备，较高工作温度的压力容器及类似结构件。  Q/BQB 320 SB410 JIS G3103 SB410  Q/BQB 321 B440HPB490HP JIS G3116 SG295SG325 焊接气瓶用钢板。  船体结构用钢 Q/BQB 330 ABD LR,BVGL,DNV 及ABS 船规 ABD 可按各国船级社规范供货。  耐大气腐蚀钢 Q/BQB 340 WTSt37-2WTSt52-3 SEW087 (EN10155) WTSt37-2 (S235J2W)WTSt52-3 (S355J 2G 1W) 用于制造集装箱、铁道车辆、石油井架、工程机械等要求耐大气腐蚀的结构件截流和燃料。  NAW 400NAW 490 NSC NAW 400NAW 490  B460NQRB490NQR --- ---  耐硫酸腐蚀钢 S-ten2 NSC S-ten2 用于制造含介质的容器等。  耐海水腐蚀钢 Mariloy G 41AMariloy S 50A Mariloy G 41AMariloy S 50A 用于采油平台、船舶、海港建筑等结构构件。  高耐候性结构钢 BZJ342 B480GNQR --- --- 用于制造车辆、集装、建筑及其它结构件。  厚度方向性能热连轧钢板 Q/BQB 350 Z15Z25Z35 --- --- 钢板厚度方向性能有良好的抗层状撕裂性能，用于海上采油平台及其它要求厚度性能的结构件。  表面硬化钢 Q/BQB 360 C 10C15 DIN 17210 C 10C15 高纯净低碳钢，供进行表面渗碳或渗氮后进行淬火硬化制造表层高硬度、耐磨、芯部具高韧性的结构件。  S09CKS15CK JIS G4051 S09CKS15CK  高韧性管线钢 BZJ 371 X60RLX70RL API 5L X60X70 供螺旋焊生产石油输送管用高韧性管线钢热轧宽带钢  直缝焊接套管用钢 BZJ 372 J55 API 5CT J55 供制造直缝焊石油套管用  花纹钢板 BZJ 390 BCP 270BCP 340BCP 400 --- --- 扁豆型花纹钢板  自行车用热连轧宽带钢 BZJ 304 SPHT1Z,SPHT2ZSPHT3Z,SPHDZSM50BZ,SM53BZ --- --- 用于制造自行车上、下、后接头，前叉肩、前花盘、链条滚车把横管，中轴等零件  管线用热连轧卷 GB 14164 S205,S240S315S290,S360,S385S415,S450,S480 API 5L Grade A,BX42,X46,X52X56,X60,X65X70 石油、天然气输送管用  1 、热连轧钢板产品简介：     热连轧钢板、带产品，是以板坯（主要为连铸坯）为原料，经加热后由粗轧机组及精轧机组制成带钢。从精轧最后一架轧机出来的热钢带通过层流冷却至设定温度，由卷取机卷成钢带卷，冷却后的钢带卷，根据用户的不同需求，经过不同的精整作业线（平整、矫直、横切或纵切、检验、称重、包装及标志等）加工而成为钢板、平整卷及纵切钢带产品。由于热连轧钢板产品具有强度高，韧性好，易于加工成型及良好的可焊接性等优良性能，因而北广泛应用于船舶、汽车、桥梁、建筑、机械、压力容器等制造行业。随着热轧尺寸精度、板形、表面质量等控制新技术的日益成熟以及新产品的不断问世，热连轧钢板、带产品得到了越来越广泛的应用并在市场上具有越来越强的竞争力。一般说明热连轧钢板产品，钢种规格品种繁多，用途广泛，从一般的工程结构至汽车、桥梁、船舶、锅炉压力容器等制造，都得到大量使用。各种不同用途，对钢板的材质性能、表面质量及尺寸、外形精度等要求也各不相同，因此，必须对热轧钢板产品的品种、材质、特性及其用途有所了解，才能做到经济、合理利用。 2 、力学性能考虑要点 力学性能名词术语（ 1 ）力学性能： 钢板的力学性能式指钢板在受力作用下所显示与弹性或非弹性反应相关或涉及应力——应变关系的性能。抗拉强度、屈服点、伸长率及冲击吸收功是表示热轧钢板力学性能的主要指标。其大小表示钢材抵抗各种作用的能力的大小，是评定钢板材料质量的主要判据，也是钢板制件设计时选材和进行强度计算的主要依据。 （ 2 ）力学性能实验： 测定热轧钢板力学性能的实验主要有拉伸试验及冲击试验等。 （ 3 ）屈服强度： 试样在拉伸过程中，负荷不增加或开始有所降低而试样仍能继续伸长（变形）时的应力。钢材的屈服强度愈低，产生永久变形所需的力愈小，即愈容易成形加工。（ 4 ）抗拉强度： 试样拉伸时，在拉断前所承受的最大应力。当材料所受的外应力大于其抗拉强度时，将会发生破裂，因此，钢板材料的抗拉强度愈大，则表示它愈能承受大的外应力而不断裂。 （ 5 ）伸长率： 试样在拉断后，其标距部分所增加的长度与原标距长度的百分比。伸长率的比数愈大，则表示材料在受力破坏前可以经受永久变形的性能（塑性）愈好；反之则塑性愈差。 （ 6 ）冲击功 （冲击吸收功）：冲击试验时，规定形状和尺寸的试样在冲击力一次作用下折断时所吸收的功，冲击功的大小，表示金属材料对冲击负荷的抵抗能力。冲击功愈高，则材料抗突然脆断的能力愈强。 3 、热连轧钢板产品的选用 1 ）力学性能与可成形性及使用性能的关系    要使钢板获得所需的形状，必须使其永久变形，所采取的工艺可以是局部或整体弯曲、深冲、张拉或这些成型方法的组合。（ 1 ）薄钢板的屈服强度表示出成形后的可成形性和强度，对普通碳素钢板的成形，屈服点值过高，常常有可能发生过大的回弹、成形时容易破断，磨具磨损快以及由于塑性不良而出现缺陷。然而材料的屈服点小于 140Mpa 时，又可能经受不住成形过程中施加的应力，对用于较复杂或复杂成形加工或冲压加工的钢板，通常要求具有比较低的屈服强度值，而且屈服比值愈小，由钢板的成形性能愈好。（ 2 ）中厚板的冷态可成形性与材料的屈服强度和伸长率有直接关系。屈服强度值愈低，产生永久变形所需的应力愈小；伸长率值愈高，高的延展性可以允许承受大的变形量而不致断裂。 （ 3 ）对用于建筑结构、桥梁及机械结构件的钢板，为防止构件断裂，要求钢板材料具有特点的抗拉强度，而为防止构件变形，又要求钢板材料具有一定的屈服强度，因此对这类用途的钢材都要求规定抗拉强度、屈服强度的最小值或范围值。 （ 4 ）对用于承受冲击负荷变形，例如船舶、桥梁、石油、天然气管线用钢板，为防止其使用中发生脆性断裂，又要求其具有一定足够高的冲击韧性 - 冲击功值。 2 ）钢板品种类别的选用 .    热连轧钢板产品包括带（卷）及由其剪切而成的钢板。而钢带（卷）又可分为直发卷及精整卷（分卷，平整分卷及纵切带卷）。    由于直发卷未经重卷，未切除钢带头尾尺寸变化部分并且未经矫直和平整，因此直发卷带有舌头和鱼尾，并且容易发生头尾厚度、宽度不均，边部浪形，折边、塔形以及开卷后出现折皱（腰折）等缺陷，因此对钢板的表面质量，板形要求比较高的用途而言，不宜选用热轧直发卷，而应选用经过精整线重卷、平整的平整卷。 5、“热轧带钢 ” 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 、 Q235 ２．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 、 65Mn ３．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） “ 冷轧带钢 ” １．产品：碳素结构钢冷轧钢带 标准：（ GB716-1991 、 QJ/HG02.22-1995 ） 规格：厚度： 0.5 -2.0mm 宽度：≤ 205mm 钢种： HG5 、 Q215 、 Q235 ２．产品：优质碳素结构钢冷轧钢带 标准： GB3522-1983 规格：厚度： 0.5 -2.0mm 宽度：≤ 205mm 钢种： 10# 、 20# 、 40Mn 、 45# 、 50# ３．产品：自行车链条用冷轧钢带 标准：（ QJ/HG02.15-1991 、 GB3522-1983 ） 规格：厚度： 0.5 -2.0mm 宽度： 125 -205mm 钢种： ZL20MnSi 用途：工业链条用、自行车变速链条用、刀具用、家具用 “ 小型材 ” １．产品：圆钢（小轧股份公司生产） 标准：（ GB699-1988 、 GB700-1988 、 GB3077-1988 、 GB702-1986 、 QJ/HG02.17-1991 ） 规格： 10 -42mm （ 10 、 12 、 14 、 16 、 18 、 20 、 22 、 25 、 28 、 30 、 32 、 34 、 35 、 36 、 38 、 40 、 42mm ） 钢种： Q215 、 Q235 、 45# 、 50# 、 HG3 、 20CrMnTi 、 20Cr 、 20CrMo 、 35CrMo 、 42CrMo 、 60Si2Mn 、 40Cr 用途：机械零件、轴、五金工具、齿轮用钢、标准件用钢等；螺铆、螺栓、轴、销、自行车、摩托车等配 件 ２．产品：螺纹钢筋 标准 :(GB1499-1991 、 BS4449:1988 ） 规格： 10 、 12 、 14 、 16 、 18 、 20 、 22 、 25 、 28 、 32 、 36 、 40mm 钢种： 20MnSi 、 20MnV 、 25MnSi 、 BS20MnSi 。 用途：建筑用材、包括可供高层建筑用材。（钢筋混凝土结构用）

不锈钢带的生产方法，不锈钢带应用到军工、汽车、电子或家电等行业，属于冷轧基板材料技术领域。特征是：选用不锈钢带坯料经第一次轧程，轧制成半成品不锈钢带；将半成品不锈钢带进入退火炉，同时充入保护气体，退火炉内的温度分为六个区域和预热段；退火结束后，再经第二次轧程，将半成品不锈钢带轧制成厚度为：０．２～０．５ｍｍ的成品不锈钢带；然后将轧制后的不锈钢带经拉直矫平，裁剪、包装为成品。本发明冷却效果好，能减少轧制道次；能降低生产成本，提高产品质量和产量；能提高表面光洁度及平直度，并能满足客户对硬度的使用要求。 不锈钢带的厚度大于1.2mm采用洛氏硬度计，测试HRB、HRC硬度。厚度为0.2～1.2mm的不锈钢带采用表面洛氏硬度计测试HRT、HRN硬度。厚度小于0.2mm的不锈钢带，采用表面洛氏硬度计配金刚石砧座，测试HR30Tm硬度。 在不锈钢带的生产过程中，有一个十分重要的工序，这就是退火－精整处理。不锈钢的退火－精整处理通常是在连续退火机组上进行的，不锈钢带以某一速度连续运动，不锈钢带的硬度主要依靠改变运动速度或调节精整压下率来调整。不锈钢带材的硬度是一项十分重要的质量指标，它关系到以不锈钢带为原料的冲压、焊管及其他变形或非变形加工的产品质量和工作效率。如何能在不停机的条件下，在生产现场快速无损地检测不锈钢带的硬度，通过现场调整工艺参数保证最终产品的硬度在规定范围之内。这是不锈钢带生产，以及冷轧钢带生产中一项亟待解决的难题。 最新生产的W－B75型韦氏硬度计较好地解决了这一问题。这种仪器有20个刻度，它采用洛氏硬度值为90HRB的标准洛氏硬度块来校正仪器，这一硬度值被设定在仪器13～14的范围内，这种仪器可以当作一台简单的HRB洛氏硬度计来使用。它可以有效地区分退火不锈钢带的软态、1/8硬、1/4硬、1/2硬及全硬状态。仪器重量不到1kg，它象一把钳子一样（俗称钳式硬度计或硬度钳），在不锈钢带上掐一下即可。测试后在不锈钢带上只留下一个极小的压痕，这个压痕既不影响外观，又不影响使用，可认为是无损检测。整个操作过程只需要1秒钟时间。这种仪器的采用可能有效地解决不锈钢带硬度的在线检测，在线控制问题。可以有效地提高不锈钢带产品的合格率，降低不锈钢带产品硬度的分散性，提高工厂的质量管理水平。我们相信这种新改进的W－B75型韦氏硬度计，在不锈钢加工行业一定会受到广泛的欢迎。

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。

热轧是在再结晶温度以上进行的轧制。可以破坏钢锭的铸造组织，细化钢材的晶粒，并消除显微组织的缺陷，从而使钢材组织密实，力学性能得到改善。这种改善主要体现在沿轧制方向上，从而使钢材在一定程度上不再是各向同性体；浇注时形成的气泡、裂纹和疏松，也可在高温和压力作用下被焊合。热轧钢管生产工艺流程 热轧无缝钢管的生产工艺流程包括坯料轧前准备、管坯加热、穿孔、轧制、定减径和钢 管冷却、精整等几个基本工序。 当今热轧无缝钢管生产的一般主要变形工序有三个：穿孔、轧管和定减径；其各自的工 艺目的和要求为： 热轧钢管生产穿孔 将实心的管坯变为空心的毛管；我们可以理解为定型，既将轧件断面定为圆环状；其设 备被称为穿孔机。对穿孔工艺的要求是：首先要保证穿出的毛管壁厚均匀，椭圆度小，几何 尺寸精度高；其次是毛管的内外表面要较光滑，不得有结疤、折叠、裂纹等缺陷；第三是要 有相应的穿孔速度和轧制周期， 以适应整个机组的生产节奏， 使毛管的终轧温度能满足轧管 机的要求。 2.1.2 热轧钢管生产轧管 将厚壁的毛管变为薄壁（接近成品壁厚）的荒管；我们可以视其为定壁，即根据后续的 工序减径量和经验公式确定本工序荒管的壁厚值； 该设备被称为轧管机。 对轧管工艺的要求 是： 第一是将厚壁毛管变成薄壁荒管 （减壁延伸） 时首先要保证荒管具有较高的壁厚均匀度； 其次荒管具有良好的内外表面质量。 2.1.3 热轧钢管生产定减径（包括张减） 大圆变小圆，简称定径；相应的设备为定（减）径机。对定减径工艺的要求是：首先在 一定的总减径率和较小的单机架减径率条件下来达到定径目的， 第二可实现使用一种规格管 坯生产多种规格成品管的任务，第三还可进一步改善钢管的外表面质量。 20 世纪 80 年代末,曾出现过试图取消轧管工序,仅使用穿孔加定减的方法生产无缝钢管, 简称 CPS,即斜轧穿孔和张减的英文缩写),并在南非的 Tosa 厂进行了工业试验,用来生产外径: ３３.４～１７９.８mm，壁厚 3.4～25mm 的钢管，其中定径最小外径为 101.6mm；张减最 大外径我 101.6mm。经过实践检验，该工艺在产生壁厚大于 10mm 的钢管时质量尚可，但 在生产壁厚小于 8mm 的钢管时通过定径、张减不能完全消除穿孔毛管的螺旋线，影响了钢 管的外观质量。在随后的改造中不得不在穿孔机于定减径机之间增设了一台 MINI-MPM(4 机架)来确保产品质量。 2.2 各热轧机组生产工艺过程特点 我们通常将毛管的壁厚加工称之为轧管。轧管是钢管成型过程中最重要的一个工序环 节。 这个环节的主要任务是按照成品钢管的要求将厚壁的毛管减薄至与成品钢管相适应的程 度，即它必须考虑到后继定、减径工序时壁厚的变化，这个环节还要提高毛管的内外表面质 量和壁厚的均匀度。 通过轧管减壁延伸工序后的管子一般称为荒管。 轧管减壁方法的基本特 点是在毛管内按上刚性芯棒，由外部工具（轧辊或模孔）对毛管壁厚进行压缩减壁。依据变 形原理和设备特点的不同，它有许多种生产方法，如表 1 所示。一般习惯根据轧管机的形式 来 命 名 热 轧 机 组 。 轧 管 机 分 单 机 架和 多 机 架 ，单 机 架 有 自动 轧 管 机 、阿 塞 尔 轧 机 、

热浸镀铝锌硅熔液中铁与铝的反应性很强也反映在对熔锅中钢带的腐蚀速度很快。经验表明，0.4mm的钢带在锅内浸泡30min就会严重腐蚀，强度很低，浸泡60min就会完全被腐蚀墁。这给生产中穿带后焊接和处理事故的时间提出了很高的要求，必须保证浸泡在锅内的钢带控制在一定的哪司内，如不及时将钢带前移一段距离就会造成锅内断带的事故，带来麻烦。一般要求0.3mm的钢带每l0min必须移动一次，0.4mm的钢带每l5min必须移动一次，0.6mm的钢带每20min必须移动一次。对钢带腐蚀作用最强的是在液面上，如发生锅内断带不能将钢带返回炉内，否则会造成炉辊的粘渣，带来更大的麻烦，可以用钳子将液面下的钢带拉出并剪去不良部分后继续焊接。

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。

不锈钢是以超过60％的铁为基体，加入络、镍、钼等合金元素的高合金钢，其最大特点是耐腐蚀能力较强，但不锈钢并非绝对不生锈。在沿海地区或某些空气污染严重的地方，当空气中氯离子含量较大时，暴露在大气中的不锈钢表面可能会有一些锈斑，但这些锈斑只限于表面，不会侵蚀不锈钢内部基体。 　　不锈钢的种类很多，按其组织分类有：奥氏体钢、铁素体钢、马氏体钢、双向不锈钢（奥氏体＋铁素体）。不锈钢大多数带有磁性，因此，用磁体吸附不是鉴别不锈钢的科学方法。 　　根据各种不锈钢的固有特性，福德太阳能热水器选用强度低，但抗锈蚀能力强、无磁性的奥氏体304钢材做水箱内胆；选用抗锈蚀能力略低，但强度高、有磁性的铁素体430钢材做支架。

板带冷轧机这一多质量、旋转运动体系统，在其高速、瞬态轧制过程中，时常会发生轧机振动现象。当轧制工艺、设备和控制等参数配合良好时，这种振动现象并不会明确体现。但是，一旦轧机运行状态超出对产品的精度要求或设备的承受能力，便会导致轧机振动的频繁发生。在带钢冷连轧过程中经常出现的传动系统扭转振动、垂直振动及垂扭耦合振动等振动形式中，以垂向系统的三倍频振动危害较大，它轻则会对轧件产品的板厚-板形质量指标造成不良的影响，重则会导致轧机设备的损害。　　　　北京科技大学的学者针对高速铝板轧制过程中频繁出现的冷轧机垂直振动现象，结合轧制工艺润滑原理和机械振动理论，建立基于辊缝动态摩擦方程的轧机垂直振动模型。该模型由辊缝几何形状模型，轧辊-轧件工作界面的动态摩擦模型，变形区内的正向轧制应力、摩擦应力分布模型，以及单机架铝板冷轧机二自由度垂向系统结构模型组成。同时，为研究轧辊--轧件工作界面动态摩擦机制影响下的冷轧机垂振机理及系统稳定性，采用某厂单机架铝轧机设备及工艺参数，搭建Matlab/Simulink平台，分别模拟仿真轧制压力和正向轧制应力曲线，验证该模型的有效性；并讨论分析了变形区混合摩擦状态，轧辊--轧件表面粗糙度、轧件入口厚度与系统稳定性的关系。

登电集团铝加工有限公司新上马的一台￠360/960×1450mm冷轧机于9月份试车成功，10月份将步入正常生产阶段。　　该公司于1997年开始筹建，拥有￠680×1600mm铸轧机两台，￠1000×1850mm铸轧机两台，￠380/1050×1800mm四重不可逆全液压冷轧机一台，年生产板、带、箔能力可达6万吨。公司原有的￠380/1050×1800mm冷轧机生产品种单一，不能满足用户的需求，尤其是生产窄料时成本高，降低了公司的利润空间。为了满足用户要求，公司决定新上一台￠360/960×1450mm冷轧机，专门生产窄料。公司在流动资金十分困难的情况下，多方筹措资金，克服重重困难，在2006年5月份开始安装￠360/960×1450mm冷轧机，7月底安装结束，创造了国内轧机安装较短时间之较。这台轧机主机电机功率大，冷却系统全部采用水冷式冷却，较大的轧制力可减少轧制道次，能够提高生产率，有效降低了窄料的生产成本。    该轧机设计轧制较薄厚度为0.08mm,试车时轧制到了0.06mm。目前，正计划投入使用，以后将以生产PS版基坯料为主。该轧机的投产，对产品的多元化、调整产品结构及新产品开发有着积极的推进作用，将会为铝加工公司创造一个新的经济增长点。
