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。

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.""

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。

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

铍铜厂家,主要分为2种，一种是国产厂家，一种就是外国厂家。外国厂家主要包括美国、日本、德国等大国的主要厂家。目前我国进口铍铜也是从这几个国家的几个核心厂家进行进口的。进口铍铜主要就是一致性好过国产铍铜，国外生产铍铜也就两家，美国的BrushWellman,日本的NGK.1.美国Brushwellman是专业做铍相关产品，绝对是 行业 的大哥大。无论是产品质量还是供货能力都是其他厂家无法比的，他们 价格 也是比较高的。2.日本NGK，铍铜仅仅是他们的一个附属 产业 ，质量可靠，产能较低， 价格 适中。3.国内铍铜处于刚起步阶段，基本集中到江苏一些小厂，质量不稳定，产能较低， 价格 低。主要是国家没有重视。铍铜的特点是良好的导热特性： 铍铜材料的导热特性有利于控制塑料加工模具的温度，也更容易控制成型周期，同时可以保证模具壁温的均匀性；如果与钢模相比，铍铜的成型周期要小的多，模具的平均温度可降低20%左右，当平均脱摸温度与模具平均壁温之间相差较小时（例如在模具零件不易被冷却的情况下）使用铍铜模具材料，冷却的时间可以减少40%。而模具壁温只降低15% ； 以上的铍铜模具材料的特性会给使用此材料的模具厂家带来几点益处 成型周期缩短，生产率提高 ； 模具壁温均匀性好，提高拉制品的质量 ； 模具结构简化，因为冷却管道减少 ； 可以提高物料温度，从而减小制品的壁厚，降低产品的成本。铍铜是一种以铍为主加元素的铜基体合金材料。其适用范围在需求高导热，高硬度，高耐磨的要求下才使用铍铜材料的。铍铜以物料形式可以分为带、板、棒，线、以及管等，如果以铍铜物理功能使用来区分，一般来讲有3种。 1：高弹性的2：高导热，高硬度的 3：电极上使用的高硬度，高耐磨的。想要了解更多铍铜厂家的相关资讯，请浏览上海 有色 网（ www.smm.cn ）铜频道。

货币政策收紧引发加息预期以及美元的走强给锌锭厂家带来了不小的压力,此外，在利空氛围中,下游消费未按预期启动更令锌锭的价格上行受阻。美元与金属价格存在很强的相关性，主要体现在两个方面：第一，美元是世界主要的支付货币之一，大宗商品以美元标价，美元上涨表示以美元计价的商品更加昂贵，资金将从大宗商品撤离转投美元避险。资金的流失对金属价格上涨不利。近期，美元指数从77附近反弹至81一线的节奏与金属价格从高位回落的步调一致。其中，美元与锌价的负相关表现特别明显。第二、美元的走强主要是美元兑非美货币的走高，美元的升值意味着非美国家的经济相对疲软，今年较去年最大的变化是宽松的货币政策面临退出。因此，靠充裕流动性推高资产价格的情况在今年不可能持续下去。欧洲债务危机问题导致的市场对经济复苏前景担忧，欧美地区消费信心下滑。欧洲地区又是全球主要的金属消费主体，经济前景堪忧势必令金属需求低迷，因此，由美元走强引发的价格下跌也在情理之中。我们预计美元的反弹会延续下去，金属价格面临美元上涨的压力。从不断高企的库存来看，全球锌锭市场的过剩要比想象中的更严重。甚至有锌锭厂家表示,他们会考虑锌锭产业对于自身的企业是否还有存在的必要 

（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。

紫铜管厂家是以紫铜管为 交易 标的或加工、贸易对象从事紫铜相关经济活动的厂家。紫铜管厂家所生产的紫铜管又称铜管。 有色金属 管一种。是压制的和拉制的无缝管。重量较轻，导热性好，低温强度高。常用于制造换热设备（如冷凝器等）。也用于制氧设备中装配低温管路。直径小的铜管常用于输有压力的液体（如润滑系统、油压系统等）和用作仪表的测压管等。铜管具备坚固、耐腐蚀的特性，而成为现代承包商在所有住宅商品房的自来水管道、供热、制冷管道安装的首选。1、紫铜管是经济的。 由于铜管容易加工和连接，使其在安装时，可以节省材料和总费用，稳定性可可靠性，可省去维修。2、紫铜管是轻便的。 对相同内径的绞螺纹管而言，铜管不需要黑色 金属 的厚度。当安装时，铜管的输送费用更小，维护更容 易，占用空间更小。3、紫铜管是可以改变形状的。 因为铜管可以弯曲、变形，它常常可以做成弯头和接头，光滑的弯曲允许铜管以任何角度折弯。4、紫铜管是易连接的。5、铜是安全的。 不渗漏、不助燃、不产生有毒气体、耐腐蚀。紫铜管厂家所追求的铜管需要质地坚硬，不易腐蚀，且耐高温、耐高压，可在多种环境中使用。与此相比，许多其他管材的缺点显而易见，比如过去住宅中多用的镀锌钢管，极易锈蚀，使用时间不长就会出现自来水发黄、水流变小等问题。还有些材料在高温下的强度会迅速降低，用于热水管时会产生不安全隐患，而铜的熔点高达摄氏1083度，热水系统的温度对铜管微不足道。 考古学家在埃及金字塔内发现了距今4500年前的铜水管，至今还能使用。紫铜管的重量计算公式,紫铜就是纯铜： 纯铜呈紫红色，又称紫铜。纯铜密度为8.96，熔点为1083℃，紫铜管的质量计算如下：G＝8.96πδ（D-δ）/1000 G：质量kg δ：管壁厚mm D：管直径mm 适宜制造紫铜管铜材的牌号为T1、T2。T1的化学成份　Cu+Ag99.95%，P0.001%，Bi0.001%，Sb0.002%，As0.002%，Fe0.005%，Ni0.002%，Pb0.003%,Sn0.002%,S0.005%，Zn0.005%，O0.02%。T2的化学成份　Cu+Ag99.95%，Bi0.001%，Sb0.002%，As0.002%，Fe0.005%，Pb0.005%,S0.005%。导热率（λ）384/W·(m·K)-1 比热熔（C) 0.394/kj·(kg·K)-1要了解紫铜管，先来看一下紫铜，紫铜就是铜单质，因其颜色为紫红色而得名。各种性质见铜。紫铜就是工业纯铜，其熔点为1083℃，无同素异构转变，相对密度为8.9，为镁的五倍。比普通钢还重约15%。其具有玫瑰红色，表面形成氧化膜后呈紫色，故一般称为紫铜。它是含有一定氧的铜，因而又称含氧铜。1.紫铜管厂家所追求的紫铜的性质紫铜 因呈紫红色而得名。它不一定是纯铜，有时还加入少量脱氧元素或其他元素,以改善材质和性能，因此也归入铜合金。中国紫铜加工材按成分可分为：普通紫铜(T1、T2、T3、T4)、无氧铜（TU1、TU2和高纯、真空无氧铜）、脱氧铜（TUP、TUMn）、添加少量合金元素的特种铜（砷铜、碲铜、银铜）四类。紫铜的电导率和热导率仅次于银，广泛用于制作导电、导热器材。紫铜在大气、海水和某些非氧化性酸（盐酸、稀硫酸）、碱、盐溶液及多种有机酸（醋酸、柠檬酸）中，有良好的耐蚀性，用于化学工业。另外，紫铜有良好的焊接性，可经冷、热塑性加工制成各种半成品和成品。20世纪70年代，紫铜的 产量 超过了其他各类铜合金的总 产量 。紫铜中的微量杂质对铜的导电、导热性能有严重影响。其中钛、磷、铁、硅等显著降低电导率,而镉、锌等则影响很小。氧、硫、硒、碲等在铜中的固溶度很小,可与铜生成脆性化合物,对导电性影响不大，但能降低加工塑性。普通紫铜在含氢或一氧化碳的还原性气氛中加热时，氢或一氧化碳易与晶界的氧化亚铜(Cu2O)作用，产生高压水蒸气或二氧化碳气体，可使铜破裂。这种现象常称为铜的“氢病”。氧对铜的焊接性有害。铋或铅与铜生成低熔点共晶，使铜产生热脆；而脆性的铋呈薄膜状分布在晶界时，又使铜产生冷脆。磷能显著降低铜的导电性,但可提高铜液的流动性,改善焊接性。适量的铅、碲、硫等能改善可切削性。紫铜退火板材的室温抗拉强度为22～25公斤力／毫米2,伸长率为45～50％，布氏硬度（HB）为35～45。紫铜垫具有优良的导电性﹑导热性﹑延展性和耐蚀性。主要用于制作发电机﹑母线﹑电缆﹑开关装置﹑变压器等电工器材和热交换器﹑管道﹑太阳能加热装置的平板集热器等导热器材。常用的铜合金分为黄铜﹑青铜﹑白铜3大类。纯净的铜是紫红色的 金属 ，俗称“紫铜”、“红铜”或“赤铜”。 紫铜富有延展性。象一滴水那么大小的纯铜，可拉成长达两公里的细丝，或压延成比床还大的几乎透明的箔。紫铜最可贵的性质是导电性能非常好，在所有的 金属 中仅次于银。但铜比银便宜得多，因此成了电气工业的“主角”。2.紫铜管厂家所生产的紫铜管主要用于的用途紫铜管的用途比纯普通紫铜广泛得多，每年有50%的铜被电解提纯为纯铜，用于电气工业。这里所说的紫铜，确实要非常纯，含铜达99.95%以上才行。极少量的杂质，特别是磷、砷、铝等，会大大降低铜的导电率。铜中含氧(炼铜时容易混入少量氧)对导电率影响很大，用于电气工业的铜一般都必须是无氧铜。另外，铅、锑、铋等杂质会使铜的结晶不能结合在一起，造成热脆，也会影响纯铜的加工。这种纯度很高的纯铜，一般用电解法精制：把不纯铜(即粗铜)作阳极，纯铜作阴极，以硫酸铜溶液为电解液。当电流通过后，阳极上不纯的铜逐渐熔解，纯铜便逐渐沉淀在阴极上。这样精制而得的铜;纯度可达99.99%。紫铜管的主要材料紫铜，是比较纯净的一种铜，一般可近似认为是纯铜，导电性、塑性都较好，但强度、硬度较差一些。 紫铜管也是继承了紫铜的良好物理、化学特性而成为工业用重要材料，在工业上具有广泛地应用，因此紫铜管厂家正是看中紫铜的这种优良的特性，才加工、 交易 紫铜管，从中获益的。

在目前铝行业市场中，电解铝的市场关注度非常高，而对于某些个人或业内人士而言对于目前的电解铝厂家的资料信息获得也是非常必要的。国内电解铝电解铝厂家生产企业分布以及大中型该类型企业名称如下：山西省：山西协和铝业有限公司、山西晋能集团新东方铝业公司内蒙古自治区： 内蒙古包头铝业有限公司辽宁省：辽宁抚顺铝厂吉林省：吉林白山市浑电铝业有限责任公司黑龙江省：黑龙江佳木斯铝厂江苏省：江苏徐州四方铝业集团公司湖北省：湖北丹江口市铝业有限公司第一电解铝分厂、湖北丹江口市铝业有限公司第二电解铝分厂、湖北武汉盛佳铝业有限公司、湖北咸宁电力铝厂湖南省：湖南张家界铝业公司、湖南双牌铝厂、湖南猫儿口铝厂广西壮族自治区：广西南南铝业股份有限公司、广西德胜铝厂、广西三江铝厂重庆市：重庆鼎泰铝业公司四川省：四川广元821厂贵州省：贵州遵义铝厂青海省：青海海北铝业有限责任公司、青海化隆先奇铝业有限责任公司宁夏回族自治区：宁夏中宁铝厂更多电解铝厂家信息可登陆上海有色网咨询，致电亦可。

贵 金属 厂家,就是指生产加工贵 金属 的厂家。贵 金属 （Precious metal），通常用来指代黄金，白银和白金三种 价格 昂贵，外表美观，化学性质稳定，具有较强的保值能力的 金属 。其中黄金的地位尤其重要。在布雷顿森林体系崩溃之前，西方各国货币均与美元挂钩，美元则与黄金挂钩，许多国家都公布本国货币的含金量，黄金的地位非常重要。1970年代後，随着世界金融格局的重组和通货膨胀得到缓解，黄金等贵 金属 的地位有所下降，但仍被视为世界通用的交换媒介和保值工具。贵 金属 在市場 交易 時，常使用鑄造成錠或幣的方式，例如黃金 交易 市場中的金條或金幣。贵 金属 的用途：航空航天材料中的贵 金属航空、航天、航海工业，要求材料具有高温抗腐蚀性、高可靠性、高精度和长的使用寿命，有的非用贵 金属 不可。如火箭点火引爆合金，航空发动机点火接点，导弹、卫星、舰艇、飞行器等控制方向、姿态的仪表材料(如陀螺仪的导电游丝)精确测温材料，应变材料等。贵 金属 催化剂及新材料的发展　　铂族 金属 具有优良的催化活性，较高的选择性、较长的使用寿命和可回收再生等优点，其研究和开发对工业和社会发展意义重大，今后许多领域必将是铂催化剂大显身手的时代。　　化学及石油化工用催化剂。80%以上的化学反应与催化有关，铂族 金属 催化剂在其中占有重要地位。如硝酸工业氨氧化用铂铑，或有铂钯铑催化网，70年来一直是硝酸工业核心。几乎年有的精细化工与贵 金属 催化剂有关使用载体催化剂，并向均相多功能催化剂方向发展。提高汽车油辛烷值的石油重整，一直离不开铂及铂及铂等基催化剂，另外，裂化、另氢等催化剂也多以铂或钯为基。　　一碳化学用催化剂、一碳化学指以煤及燃气，即甲烷、一氧化碳、甲醇等分子内含一个碳原子的物质为原料，制备各种化学制品和新兴工业领域。这方面最前途的是铂族 金属 配合物或 金属 化物催化剂。　　不锈钢表面有0.003 m的钝化膜，因此导电性变差，不能钎焊，限制了在电子工业中的应用。但是只要在不锈钢表面镀0.1~0.5 m厚的金，就有了导电性和钎焊性，从而开辟了在电子工业中的应用。　　贵 金属 应用极广，在高新技术的发展中处于重要地位。随着科学技术的发展，其应用领域和用途还会扩大，起越来越重要作用想要了解更多关于贵 金属 厂家的资讯，请继续浏览上海 有色 网（ www.smm.cn ） 有色金属 频道。

关于热镀锌厂家的相关信息：热镀锌厂与电镀锌厂相对，主要生产热镀锌产品，且热镀锌钢材产品的适用范围广，供不应求。热镀锌（galvanizing），也叫热浸锌和热浸镀锌，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。热镀锌的生产工序主要包括：原板准备→镀前处理→热浸镀→镀后处理→成品检验等。根据镀前处理方法的不同把热镀锌工艺分为线外退火和线内退火两大类 。线外退火：就是热轧或冷轧钢板进入热镀锌作业线之前，首先在抽底式退火炉或罩式退火炉中进行再结晶退火，这样，镀锌线就不存在退火工序了。钢板在热镀锌之前必须保持一个无氧化物和其他脏物存在的洁净的纯铁活性表面。这种方法是先由酸洗的方法把经退火的表面氧化铁皮清除，然后涂上一层由氯化锌或由氯化铵和氯化锌混合组成的溶剂进行保护，从而防止钢板再被氧化。线内退火：就是由冷轧或热轧车间直接提供带卷作为热镀锌的原板，在热镀锌作业线内进行气体保护再结晶退火。热镀锌产品性能的影响因素：碳、硫、磷、锰、硅、钨、铬等。随着工业的发现，热镀锌厂家的加工产品已经运用到很多领域，热镀锌加工的优点在于防腐年限长久，适应环境广泛一直是很受欢迎的防腐处理方法。被广泛运用与电力铁塔、通信铁塔、铁路、公路防护、路灯杆、船用构件、建筑钢结构构件、变电站附属设施、轻工业等。

裸铜线厂家在全国范围来看非常的多，这时由于在目前的铜线 市场 上，对于铜线的需求量还是很大的。    裸铜线、镀锡铜线、铜包铝线被广泛用于编织屏蔽网，因材料差异，导致弱电线缆 市场 鱼龙混杂。铜包铝线与裸铜线外观颜色相同，初看之下，很难区别，具有极大的迷惑性。各种编织网材料孰优孰劣，也让广大工程商朋友感到困惑，无从鉴别。下面就为大家介绍一些区分裸铜线、镀锡铜线以及铜包铝线的常规方法。以视频线SYV75-5编织网为检测对象，可采用以下方法：　　1、目测外观。剥去视频线外被，可迅速把镀锡铜线从三种线材料中识别出来，因为只有镀锡铜线为银色，另外两种皆为黄色。接下来垂直整齐切下一段视频线，看编织网截面，如果为黄色，即为裸铜线；如果为白色，即为铜包铝线。三种编织网的用线材料于是区分开来　　2、用工具发刮擦视频线编织网表面，镀锡铜网刮擦后显现黄色，裸铜网仍是黄色，而铜包铝网则出现雪花点白色。将视频线编织网置于水泥地面上磨擦也能得到同样效果。　　3、过火测试。将视频线编织网拆散开，拨向一侧，接近火焰，如果灼烧后形成球珠状物体的即为铜料；如果 金属 丝灼烧后变白，且下垂用手碰触即碎的为铜包铝网。  裸铜线、镀锡铜线、铜包铝线及其区分铜包铝线构成与区别:裸铜线就是用纯铜杆拉丝而成的铜线，质料单一，表里皆铜 金属 ，外观看过去为黄色，且因铜纯度的高低使颜色有深有浅。物理性能上，裸铜线材质柔软，导电性能优良。镀锡铜线的工艺比裸铜线稍稍复杂些，将纯铜杆拉成丝后再用热镀锡工艺在铜丝表面镀上薄薄的一层锡就成了镀锡铜线。这种线外观为银色，因为锡是银色 金属 的缘故。镀锡铜线，材质比较柔软，导电性能良好，与裸铜线相比，其耐蚀性、抗氧化性能更强，可大大延长弱电线缆的使用寿命。铜包铝线采用包覆焊接制造技术，将铜带同心地包覆在铝杆芯线的外表面，并使铜层和芯线之间形成牢固的原子间的冶金结合，使两种不同的 金属 材料结合成为不可分割的整体，可以象加工单一 金属 丝那样作拉拔和退火处理，拉拔过程中铜和铝同比例地变径，铜层体积比则保持相对恒定不变。铜包铝线重量很轻，外观上也呈现黄色，但相较前两者，导电性能差许多，柔韧度不够，易折断，耐蚀性、抗氧化性能也比较低。如果铜包铝生产工艺控制不好，那么铜包铝成品很可能在短时间内成为一堆废品。      更多关于裸铜线厂家的相关信息请关注上海 有色 网。

铝箔，指的是一种用金属铝直接压延成薄片的烫印材料，其烫印效果与纯银箔烫印的效果相似，故又称假银箔。铝箔在包装领域又极为广泛的应用，其中，以8系的8021、8011铝箔较为常见。　　　　按照形状来分，8系铝箔可以分为卷状铝箔和片状铝箔，按表面状态可分为一面光铝箔和两面光铝箔。按照后期不同的加工方法，铝箔也可以分为素箔、压花箔、复合铝箔、涂层箔、上色铝箔、印刷铝箔。　　　　8系铝箔是食药包装、电子电器中常用的合金。我们以8011铝箔为例来看，8011铝箔的加工发展在我国已有稳定基础，是众多铝加工企业的重点产品之一。以河南省巩义市的铝加工产业集聚区为例，就有数十家大大小小的铝加工企业。8011铝箔厂家众多，在采购产品的时候，如何选择一家实力雄厚的8011铝箔厂家呢?　　　　一、看产品质量、性能。　　　　优质的铝箔厂家应该完全保证产品质量过硬、性能优越。如明泰铝业生产的8011铝箔能够做到表面良好，光泽均匀;产品的厚度无误差，规格精准;铝箔表面无亮点、亮痕;对产品生产过程全程监控，确保无残留、水斑等。　　　　二、看铝箔厂家的综合实力　　　　综合实力较强的企业，能为产品的优越性能保驾护航。生产规模、年产能力、产品质量等方面是检验铝箔厂家的重要因素。明泰铝业年产能力40万吨以上，职工2800余人，铝板带箔产品销往全球40多个国家和地区。　　　　三、看售后　　　　与一般商品相比，铝箔等产品属于大型货物，因此，产品的物流及售后问题显得更为重要，大型的8011生产厂家可以及时跟踪采购企业的相关情况，提供售后服务或者解决者其他问题，为产品的退换货保障提供无忧服务。

镀锌板厂家，顾名思义，就是供应热镀锌板、电镀锌板等钢材。下面是关于镀锌板厂家的相关信息：镀锌板是指表面镀有一层锌的钢板。镀锌是一种经常采用的经济而有效的防腐方法。全世界锌 产量 的一半左右均用于此种工艺。镀锌是为防止钢板表面遭受腐蚀延长其使用寿命。镀锌板的外观1.表面状态：镀锌板由于涂镀工艺中处理方式不同，表面状态也不同，如普通锌花、细锌花、平整锌花、无锌花以及磷化处理的表面等。　　2.镀锌板应具有良好的外观，不得有对产品使用有害的缺陷，如无镀、孔洞、破裂以及浮渣、超过镀厚、擦伤、铬酸污垢、白锈等。热镀锌板是将薄钢板浸入熔解的锌槽中，使其表面粘附一层锌的薄钢板。目前主要采用连续镀锌工艺生产，即把成卷的钢板连续浸在熔解有锌的镀槽中制成镀锌钢板。电镀锌板是用电镀法制造这种镀锌钢板具有良好的加工性，但镀层较薄，耐腐蚀性不如热浸法镀锌板。近几年，我国镀锌板消费量不断增长，所以镀锌板厂家生产的镀锌板供不应求，导致镀锌板产品 价格 上浮。

多晶硅厂家是生产多晶硅的。多晶硅厂家在国内 市场 竞争激烈，还要应对国外厂家的竞争。多晶硅可作拉制单晶硅的原料，多晶硅与单晶硅的差异主要表现在物理性质方面。例如，在力学性质、光学性质和热学性质的各向异性方面，远不如单晶硅明显；在电学性质方面，多晶硅晶体的导电性也远不如单晶硅显著，甚至于几乎没有导电性。在化学活性方面，两者的差异极小。多晶硅和单晶硅可从外观上加以区别，但真正的鉴别须通过分析测定晶体的晶面方向、导电类型和电阻率等。 　　多晶硅是生产单晶硅的直接原料，是当代人工智能、自动控制、信息处理、光电转换等半导体器件的电子信息基础材料。被称为“微电子大厦的基石”。多晶硅生产过程中主要危险、有害物质中氯气、氢气、三氯氢硅、氯化氢等主要危险特性有： 　　１）氢气：与空气混合能形成爆炸性混合物，遇热或明火即会发生爆炸。气体比空气轻，在室内使用和储存时，漏气上升滞留屋顶不易排出，遇火星会引起爆炸。氢气与氟、氯、溴等卤素会剧烈反应。 　　２）氧气：易燃物、可燃物燃烧爆炸的基本要素之一，能氧化大多数活性物质。与易燃物(如乙炔、甲烷等)形成有爆炸性的混合物。 　　３）氯：有刺激性气味，能与许多化学品发生爆炸或生成爆炸性物质。几乎对 金属 和非 金属 都起腐蚀作用。属高毒类。是一种强烈的刺激性气体。 　　４）氯化氢：无水氯化氢无腐蚀性，但遇水时有强腐蚀性。能与一些活性 金属 粉末发生反应，放出氢气。遇氰化物能产生剧毒的氰化氢气体。 　　５）三氯氢硅：遇明火强烈燃烧。受高热分解产生有毒的氯化物气体。与氧化剂发生反应，有燃烧危险。极易挥发，在空气中发烟，遇水或水蒸气能产生热和有毒的腐蚀性烟雾。燃烧(分解)产物:氯化氢、氧化硅。 　　６）四氯化硅：受热或遇水分解放热，放出有毒的腐蚀性烟气。 　　７）氢氟酸：腐蚀性极强。遇H发泡剂立即燃烧。能与普通 金属 发生反应,放出氢气而与空气形成爆炸性混合物。 　　８）硝酸：具有强氧化性。与易燃物(如苯)和有机物(如糖、纤维素等)接触会发生剧烈反应，甚至引起燃烧。与碱 金属 能发生剧烈反应。具有强腐蚀性。 　　９）氮气：若遇高热，容器内压增大。有开裂和爆炸的危险。 　　１０）氟化氢：腐蚀性极强。若遇高热，容器内压增大，有开裂和爆炸的危险。 　　１１）氢氧化钠：本品不燃,具强腐蚀性、强刺激性，可致人体灼伤。想要了解更多多晶硅厂家的相关资讯，请浏览上海 有色 网（ www.smm.cn ） 有色金属 频道。
