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

关于进口铅锭方面的消息，据上海有色网专家称在前几个星期某天上午在与冶炼和蓄电池企业交流行情时，我们得到一个重要信息，据他们介绍近日有一批近2万吨的国外进口铅锭已经抵达上海、广州港口，这批铅锭价格在15000~16000元/吨，目前正在办理入关事宜，我们认为近期国外消费市场的疲软使LME铅价连连走低，而国内现货价格在厂家货源短缺惜售的支撑下表现相对坚挺，两者之间的价格差距也开始逐渐拉大，在这种情况下部分商家可能已经瞄准这一契机，从国外采购相对质优价廉的进口铅锭在国内销售。                                  冶炼企业在与我们交流有关进口铅锭此事时指出他们正在确认这个消息的真实性，如果确有此事，他们认为这将对冶炼企业及整个国内铅市产生较大冲击，因为国外铅锭价格低于国内价格，质量方面也较好，下游企业将会将采购目标转向这批国外进口铅锭，而目前各厂家都有一定数量的库存在等待9月份左右的旺季销售，这么大数量的国外进口铅锭进入市场后难免会使一些厂家出现恐慌出货，国内货源供应大量增加，现货价格将可能再所难免的出现下滑。上海有色网专家表示近期一定会跟进这一批进口铅锭的相关信息，在获取信息后会第一时间反馈在我们上海有色网相关版块上供各位用户获取最新的资讯，相信通过我们的努力一定能够使您受益匪浅。

进口废铜,据小编了解，自2007年来，国家就对铜的进口税务降低，铜废碎料的关税将从1.5%下调至0％。国内部分贸易商认为，这一新税政策意在鼓励我国的废铜进口，这将对不断震荡下行的期铜价格雪上加霜。　　在此新税政策中，涉及铜相关产品的关税调整主要包括：未精炼铜、电解精炼用铜阳极从2％调整至0％；铜废碎料从1.5%下调至0％；覆铜板及印刷线路板用铜箔从4％下调至1％。据国内部分贸易商介绍，在这些被调整的产品中，对将来铜价影响最大的是废铜碎料的调整，这可能会刺激更多的进口铜需求被废铜所替代，从而抑制铜价上涨。　　我国1至11月未锻造铜及铜材进口同比下降21％至186万吨。但新近统计出来的废铜进口数据却增长迅速：11月进口量为55.44万吨，同比增加了30.3％；1至11月进口量为447.5万吨，同比增长1.1%。一些贸易商反映，由于大量的废铜走私数量无法统计，其实真实的废铜进口数量将远大于海关统计的数据。这之间的一增一降的数据就可以反映出，目前国内废铜的进口量将对铜价产生较大的影响。上海迈科金属资源有限公司总经理吴剑曾表示，中国今年电解铜进口减少缺口主要被以下三方面弥补，其中一点就是进口废杂铜的含铜量的增加以及国储的释放库存行为和企业的消库行为。　　据金龙铜管的陆承红介绍，其实废铜经过冶炼之后也可以加工为电解铜，但这种做法并不是废铜替代。今年大量的废铜替代只是不经过冶炼，而是加热之后，直接代替电解铜使用。除废铜替代会对铜价产生影响外，废铜进口关税的下调，对通过废铜冶炼提炼出电解铜的价格也会产生影响，下调1.5%，则其提炼出的电解铜价格下调的幅度可能为：1.5%乘以废铜的含铜比率。　　昨日，沪期铜价格在深度下探后有所反弹，主力0702合约上涨了830元/吨，收于60690元/吨，较上一交易日上涨了1.39%。　　但从目前的情况看，随着生产环节库存的降低，企业消库行为对废铜进口的弥补作用已经不大；而国储可能不再继续放货。由此看来，目前这三方面因素中，明年可能只剩下废铜进口替代因素仍旧可以起作用。

目前来说,进口锌锭的情况受中国工业生产减缓的影响较大,预计在缺乏持续向好的经济数据支撑下，进口锌锭的价格短期将难以避免出现回调。基本面上，受消费淡季影响，国内锌下游企业采购意愿不强，锌锭供应过剩局面依然严峻。虽然供应过剩量较二三月份有了较大改善，但下半年供需状况依然十分严峻。此外，上半年政府对房地产行业出台一系列调控措施，极大打压下游企业锌需求，导致上半年锌出现严重供应过剩。下半年，政府对房地产行业的调整将不会放松，建筑业对锌需求提高将非常有限。另外，今年7月份我国汽车产销继续呈下滑态势，延续了往年淡季行情。在产销下滑的同时，库存开始上升。7月份，汽车库存周期逐月增长势头依然延续，由6月份的55天增加到58天。库存压力加大势必会对锌需求构成打压。从市场反馈来看,进口锌锭的这种情况还将持续一段时间,在这期间,如何合理安排销售策略,是各大贸易商待解决的问题 

废铜进口，废铜进口,全球最大的金属消费国--中国的废铜、废铝和废锌进口量可能下滑，因海关将执行更严格的检查以打击进口商逃税和走私活动.4月份未锻造铜及铜材进口量环比下降，而废铜进口量呈现继续攀升走势，表明国内铜市场需求继续保持旺盛。沪铜10日领涨国内基本金属。在基本金属价格经过连续下跌之后，10日受美国4月份就业数据走强影响，国内基本金属呈现全线上涨态势，其中沪铜1008合约以3.02%涨幅领涨国内基本金属。中国海关最新数据显示，4月份中国废铜进口量环比增长1.4%，达到2010年来新高，这较大的提振市场人气，相对精炼铜进口量来说，废铜进口情况更能反应市场需求状况。未锻造铜及铜材进口量在4月份有所回落。与3月份相比，4月份中国未锻造铜及铜材进口量下降了4.4%。其原因一方面跟废铜进口增加有关，因部分废铜替代了精铜进口量。另一方面跟铜沪伦比值在4月份偏低有关，4月份铜沪伦比值在8.0下方徘徊，导致进口伦铜行为难以发生。而2月份的套利进口铜大多在3月份已经抵达国内，对4月份铜进口影响不大，这也导致4月份中国铜进口量环比下滑，但436,345万吨的进口量依然处于高位，显示国内市场对铜需求依然强劲。中国有色金属工业协会再生金属分会会长王恭敏称，将从6月1日起实施的新规定将“提高废金属贸易商和回收商的成本，并且可能迫使部分关闭。”据该协会的预估，中国可能从废金属中生产其40%的铜和30%的铝，取代来自矿山的产量。贸易商称，废铜供应缺乏刺激了2009年精炼铜进口激增。铜价去年上涨逾一倍，因创纪录的中国进口推动。　　　　王恭敏称，废金属装船短期内因新规定影响可能下滑，因为需要使交易标准化。长期来看，金属价格也将对进口量起到作用。废铜进口.

铝锭进口相关知识很多，让我们对它进行下介绍。【法规名称】财政部、对外贸易经济合作部、国家发展计划委员会、海关总署关于明确边贸进口铝锭税收政/策问题的通知【颁布机构】财政部、对外贸易经济合作部、国家发展计划委员会、海关总署【法规类别】税则【有 效 性】有效【颁布时间】2001-7-10【实施时间】2001-7-10【正 文】财政部、对外贸易经济合作部、国家发展计划委员会、海关总署关于明确边贸进口铝锭税收政策问题的通知财税[2001]101号 内蒙古自治区、辽宁省、吉林省、黑龙江省、广西壮族自治区、云南省、西藏自治区、甘肃省、新疆维吾尔自治区财政厅（局）、外经贸委（厅、局），新疆生产建设兵团财务局、外经贸委（厅、局），海南省财政厅、商业贸易厅，哈尔滨、长春、大连、乌鲁木齐、呼和浩特、满洲里、南宁、海口、昆明、拉萨、兰州海关：为规范边贸进口铝锭秩序，维护国内铝锭市场稳定，经国务院批准，现就边贸进口铝锭税收政策问题通知如下：自2001年7月15日起，对以边境小额贸易方式进口铝锭（税号为76011000）暂停执行减半征收进口关税和进口环节增值税的政策，一律按法定税率征收进口关税和进口环节增值税。  特此通知。财政部对外贸易经济合作部国家发展计划委员会海关总署二○○一年七月十日据海关统计，今年9月份我国铝锭进口10.4万吨，同比增长197%。1至9月份共计进口铝锭63.5万吨，同比增长74.5%。1至9月份进口量已经超过历年来全年的产量。其中从俄罗斯进口的大量低价铝锭对国内市场造成较大冲击。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。通过了解铝锭进口的知识，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。 

进口铝锭是一种投资者想要了解的一个情况，让我们来了解下。供应A00铝锭 进口铝锭销售范围：全国产品数量：1000 吨商品价格：8800发布日期：2010-01-24一、减产见成效，铝厂去库存化效果明显至去年中国引领铝冶炼行业减产以来，进入2月全球又有部分铝生产商加入减产行列，其中包括俄铝宣布将原铝产量减少11%，氧化铝产量下调30%，并裁员5%，以应对经济危机。据安泰科统计，截止1月中旬，全球累计宣称减产规模达189万吨/年，是2000年以来最大的一次联合减产行动。国际铝业协会（IAI）公布的数据显示，1月份全球原铝产量为210.6万吨，2008年12月份为213万吨，而2008年1月为217.6万吨，原铝日产量连续3个月出现下滑；国内方面，1月原铝产量为92.2万吨，较去年12月减少2.4万吨，原铝日产量以连续4个月下降。如图3所示：据了解，目前因减产和收储等影响，铝厂库存普遍较低，这也成为支撑近期铝价的有利因素，预期减产效果将在第二季度集中体现，市场供需失衡的状况将有所改观。二、注销仓单增加，是需求回暖还是跨市套利？高库存压力一直成为抑制金属走势的主旋律。去年12月以来，随着隐形库存的显性化，外围金属库存呈现加速增长态势，截止2月底，伦铝库存增幅140万吨，伦铜库存增加25万吨，伦锌库存增加17万吨，增幅分别为77.4%、87%和87.6%。因国内收储的实施，国内外金属价格逐渐出现分化，内强外弱的格局令金属市场套利空间被打开，在2月呈现逐步扩大的局面。从国家统计局公布的数据显示来看，1月份国内金属进口大增，其中原铝进口1.7万吨，同比增加18.66%，精铜进口18万吨，虽较去年12月有所减少，但进口数量依然很高，精锌进口1.3万吨，而2008年12月仅为3306吨。中国金属进口的增多，带动伦敦金属发生微妙变化，1月注销仓单小幅增加，2月下旬注销仓单增加开始加速，如图1所示，伦锌和伦铜注销仓单占比在2月增加急速，而伦铝注销仓单占比虽有所提高，但受制于库存过高，反映比较迟滞。注销仓单的增加，无疑与国内进口增加有关，市场疑虑是需求回暖还是跨市套利？通过分析，认为需求回暖带动大批进口的可能性不大。首先，经济领先指标PMI显示虽然国内PMI连续三个月回升，美国PMI亦出现两个月的回暖，但目前仍然低于50的分界点，表明市场需求整体上依然疲弱，仅仅是需求衰退有所减缓而已；其次，国内进口大增的政策背景较为深远，多数型材厂利用加工贸易手册进口原铝，但受国外订单数量影响，进口数量相对巨量库存而言实为杯水车薪；相比之下，更为重要的是，套利空间打开为贸易商提供了千载难逢的机会，关税调整的延后，吸引更多商家加入，据了解节后贸易商进口铝锭到港陆续增多，因此，从一定程度上，国内进口的增多则近乎于国际间铝锭库存的转移。三、收储加重现货紧缺，期货价差不断扩大继国储去年12月收储铝29万吨以来，市场多预期春节后展开后续收储，对节后铝价起到良好支撑。2月23日，国储从国内企业收储29万吨原铝，近半数来自中铝，收储价12490-12500元/吨，较12月收储高1%。国内收储在一定程度上助长了国内短期货源紧张的状况，据安泰科预测，2008年国内原铝供给过剩52万吨，两次收储总量基本消除了国内过剩库存，因此目前主要铝厂库存多维持低位，同时通过对上海、无锡和广东三地仓库库存的统计，节后三地库存经历了先增后减的过程，并且库存减少的趋势有望持续，如图4所示。现货方面，市面可流通货源趋紧与下游低迷消费并存，铝价沦入僵持状态。上游厂家持货减少，惜售情绪浓厚，2月以来，只有当铝价位于12000元/吨以上上游出货意愿才有所增强，下游消费低迷，沪粤两地下游厂家经营压力较大，大型厂家多利用加工贸易维系生产，近期对进口铝的依赖增强，一定程度上抑制了购进国内铝锭的需求，因此在价格跌至12000元/吨以下勉强购货，这也成为近一个月铝价窄幅震荡的主因之一。现货铝价的坚挺，导致沪铝跨期价差不断增大，如图5所示，短期市面供应紧张的局面凸显无疑，但远期铝价走势不确定性仍旧很大，主要受制于国内供需强弱的对比关系。四、综述2月份，铝价在狭窄的空间持续整理，市面陷入僵持局面。国内外减产效果显现，减缓对市场的供给冲击，加之国内两次收储的实施，供给方面显示出有利于稳定目前铝价水平；注销仓单的增多，以及国内铝进口的增多，令市场开始寄希望于中国需求元素，但市场需求面并为发生实质性性好转，而进口的增多在反映出国内政策面含义的同时，投机性的套利交易或许能承担更好的解释。通过上述分析，我们预计3月份市场供给延续紧张，或将成为铝市供需强弱转换的关键时机，但受制于进口流入数量的不确定以及需求改善状况，料铝价震荡空间上移。如果你想更多的了解关于进口铝锭的信息，你可以登陆上海有色网进行查询和关注。

 废钢和废铜是 金属 加工的重要原材料。历年来，我国两大废 金属 的进口依存度极高，其中国内废钢每年缺口约在500万吨以上，而废铜更有3/4以上依赖进口。2001年我国已经取代韩国、土耳其成为全国最大的废钢和废铜进口国。而废 金属 作为一种战略资源地也已越来越得到世界的普遍重视，各主要供应国纷纷出台措施限制废 金属 出口。受此影响，2006年1-8月，上海口岸两大废 金属 进口量减价增，共进口34.4万吨，比去年同期下降25.2%；进口金额2.7亿美元，下降8.1%。其中，一般贸易进口33.6万吨，占口岸两大废 金属 进口总量的97.6%。在国内废 金属 需求持续旺盛的情况下，进口量的减少已经一起来国内 市场 的连锁反应。2006年8月，上海废铜 市场 的光亮铜线 价格 为62500元/顿，与4月初相比涨幅高达17200元/吨，国内库存也随之大幅减少，国内 市场 废 金属 供应吃紧隐含了我国再生 金属行业 所存在的2大突出问题。主要进口品种进口 价格 全面上涨。今年1-9月天津口岸废 金属 进口96.4万吨，其中废铜进口45.4万吨，占废 金属 进口总量的47.1%。今年以来，天津口岸废铜进口平均 价格 由1月份的942.5美元/吨激增至9月份的1924美元/吨，9个月间上涨1.04倍。此外，废钢进口平均 价格 由1月份的282.6美元/吨上涨至9月份的312.3美元/吨，废铝进口平均 价格 由1月份的802.7美元/吨上涨至9月份的1003美元/吨。 近期天津口岸废 金属 进口 价格 上涨的主要原因。    年初以来，废 金属价格 大幅下降主要是受全球 金属期货价格 下降的影响。而随着近期铜等主要 金属期货价格 回暖，废 金属 进口 价格 也水涨船高。此外，金融危机以来，全球经济下滑，欧美等西方发达国家受到更严重打击。经济发展的放缓造成新工程开工率下降，汽车等主要 金属 下游产品更替率放缓，直接导致其废铜、废钢等废旧 金属 的产出量下降。供应趋紧也是近期国际废旧 金属市场价格 上涨的主要原因之一。   值得关注的问题    由于铜价仅在去年10月份的跌幅就超过46%，远远高于废杂铜进口企业预先支付给国外贸易商20%的保证金，因此在面对巨额亏损时大多数废杂铜进口企业选择违约，取消了部分订单。在将亏损转移给国外废杂铜贸易商的同时，也失去了对方的信任，部分企业停止向我国的企业供货。即使是继续向我国出口废杂铜的贸易商，也大幅提高了贸易条件。一些 交易 商称，供应商已要求我国进口商支付更高的订金，占合同总价中的比例已从先前10-30%的水平提高到30-50%。在资金本已十分紧张的情况下，预付款的大幅提高加大了废杂铜进口的难度，废杂铜进口渠道的重建尚需时日，废杂铜进口在短期内仍将维持在较低水平。更多有关废 金属 进口请详见于上海 有色 网

进口废铝是目前对于废铝市场来说一个主要采购方式。据海关统计显示，我国2010年前来两个月中国的进口废铝17.4万吨，同比增加63.2%；前两个月进口废铝累计42.7万，比去年同期增加了127.3%。由于春节原因，2月份往往是一年之中进口废铝数量最少的。环比2010年1月份的25.3万吨，2月份进口废铝数量下降了近3成，这也是自2009年7月份以来废铝单月进口数量首次下降到20万吨以下水平。另外，铝行业市场价格也对进口废铝产生了一定的影响，考虑到运输周期，2010年2月份到港的废铝一般是2009年12月和2010年1月份签订的合同，当时较低的国内外铝比价也不利于中国的进口废铝。2月份国内外铝比价重新回到8以上水平，预计会对3月份的进口废铝有较大促进，而从一段时间以来的国外废铝市场来看，中国也确实加大了采购力度，欧美废铝市场已经出现偏紧的趋向。

废铜进口,未来几个月中国废铜的进口将从今期的滔滔洪流变为涓涓细流, 因为中国提高了废铜进口关税。新关税实行的时间正是美国废铜供给旺盛之时, 有报道称在实施新关税的消息公布后, 中国对2号废铜的需求量已开始大幅下降。今年上半年中国一直在不断进口废铜。一月至五月中国从美国进口的废铜达68,818 吨, 这是在过去九年中从未发生过的。五月中国进口的废铜就达18,035吨,为中国单月废铜进口量之最, 其中从美国进口的废铜超过了总进口量的40%。中国一直对铜产品进口实施高于70%的关税。市场观察家说如果这一税率被严格执行, 低级的2号废铜进口量将降为零。但几位美国的废铜出口商却说目前还不清楚新关税会对他们的出口产生什么影响。 另有出口商说近几周中国废铜的进口量已开始下降, 但他们希望中国旺盛的废铜进口能够尽快恢复。政府在网站上称，总理普京已经签署取消关税的法令。零关税政策将在法令正式刊登在政府公报上一个月后生效，通常在网站上公布后的数日。政府海外贸易保护措施委员会于1月底推荐取消关税。中国一直是2号废铜的主要进口商之一, 尤其偏爱进口北美和欧洲低级的废铜线和铜缆。小编了解到俄罗斯政府表示，该国将取消废铜5%的进口关税，时间为9个月，以此增加国内铜精炼厂原材料的供应，总理普京已经签署取消关税的法令。综合外电4月8日报道，俄罗斯政府7日表示，该国将取消废铜5%的进口关税，时间为9个月，以此增加国内铜精炼厂原材料的供应。废铜进口关税在俄罗斯第三大铜生产商--俄罗斯铜业公司表示，2008年该公司不得不削减旗下两座精炼厂的产量，因市场上废铜短缺。

废铝进口是目前对于废铝市场来说一个主要采购方式。据海关统计显示，我国2010年前来两个月中国的废铝进口17.4万吨，同比增加63.2%；前两个月废铝进口累计42.7万，比去年同期增加了127.3%。由于春节原因，2月份往往是一年之中废铝进口数量最少的。环比2010年1月份的25.3万吨，2月份废铝进口数量下降了近3成，这也是自2009年7月份以来废铝单月进口数量首次下降到20万吨以下水平。另外，铝行业市场价格也对废铝进口产生了一定的影响，考虑到运输周期，2010年2月份到港的废铝一般是2009年12月和2010年1月份签订的合同，当时较低的国内外铝比价也不利于中国的废铝进口。2月份国内外铝比价重新回到8以上水平，预计会对3月份的废铝进口有较大促进，而从一段时间以来的国外废铝市场来看，中国也确实加大了采购力度，欧美废铝市场已经出现偏紧的趋向。 

进口铜精矿         年以来南通口岸进口铜精矿巨量短重频发。1-3月份该局共检验进口铜精矿37批次，重量累计37.18万吨，其中发现短重6批次，累计短少1846.9公吨，短少货值1896万元人民币，短少重量和货值均超去年全年总和。南通检验检疫局及时出具重量检验证书供企业索赔，挽回了巨额损失。   从各月具体情况来看，进口铜精矿短重问题呈逐月上升趋势。1月短重1批次，重量134.6吨，金额132.2万元人民币；2月短重2批次，短重361.3吨，金额467.4万元人民币；到了3月份，短重问题尤为严重，连续发现3批短少全部超过400吨，其中一批短少430吨，占提单列明重量的3.88%，短少金额578.7万元人民币。就货物产地来看，来自南美地区的智利和秘鲁两国的铜精矿短重问题最为严重，在1季度发现的短重批次中，除有1船来自澳大利亚外，其他5船皆来自上述两国。　　铜精矿是进口矿产品中货值最高的货种之一，随着各国经济的复苏，铜精矿 价格 也水涨船高，去年全年南通口岸进口的铜精矿均价为1183美元每吨，而今年1-3月均价已经高达1797美元，涨幅51.9%。　　作为全国最大的进口铜精矿集散地之一，南通港接卸中转铜精矿已有20多年的历史。目前，该口岸进口铜精矿的接卸量已经连续数年超过100万吨，基本稳定在全国同期进口总量的20%上下。　　从该局多年来的检验数据来看，进口铜精矿短少频繁出现，主要原因有：一是国外发货人恶意短装，借此牟取暴利；二是承运船舶船况较差，不适合进行水尺计重；三是国外装货港风浪过大，导致检验数据出现巨大误差。更多关于进口铜精矿信息请详见上海 有色金属 网

进口红铜顾名思义就是从国外进口的红铜。红铜即纯铜，又名紫铜，具有很好的导电性和导热性，塑性极好，易于热压和冷压力加工，大量用于制造电线、电缆、电刷、电火花专用电蚀铜等要求导电性良好的产品。因此进口红铜在整个铜业进口中占有举足轻重的地位。　　进口红（赤）铜。由硫化物或氧化物铜矿石冶炼得来的纯铜，可用以铸钱及制作器物。 明 宋应星 《天工开物·铜》：“凡铜供世用，出山与出炉，止有赤铜。以炉甘石或倭铅参和，转色为黄铜；以砒霜等药制炼为白铜；矾、硝等药制炼为青铜；广锡参和为响铜；倭铅和写﹝泻﹞为铸铜。初质则一味红铜而已。”郭沫若 《中国史稿》第一编第三章第二节：“他们冶炼的红铜成分很纯，除天然的微量（0.1－0.2％）杂质外，没有人工加入锡或铅使成合金。红铜的硬度虽较差，但直接经过捶打就能制成各种工具和装饰品。”进口红铜即进口纯铜，又名紫铜，具有很好的导电性和导热性，塑性极好，易于热压和冷压力加工，大量用于制造电线、电缆、电刷、电火花专用电蚀铜等要求导电性良好的产品。即赤铜。由硫化物或氧化物铜矿石冶炼得来的纯铜，可用以铸钱及制作器物。 明 宋应星 《天工开物·铜》：“凡铜供世用，出山与出炉，止有赤铜。以炉甘石或倭铅参和，转色为黄铜；以砒霜等药制炼为白铜；矾、硝等药制炼为青铜；广锡参和为响铜；倭铅和写﹝泻﹞为铸铜。初质则一味红铜而已。”郭沫若 《中国史稿》第一编第三章第二节：“他们冶炼的红铜成分很纯，除天然的微量（0.1－0.2％）杂质外，没有人工加入锡或铅使成合金。红铜的硬度虽较差，但直接经过捶打就能制成各种工具和装饰品。” 红铜即纯铜，又名紫铜，具有很好的导电性和导热性，塑性极好，易于热压和冷压力加工，大量用于制造电线、电缆、电刷、电火花专用电蚀铜等要求导电性良好的产品。　　即赤铜。由硫化物或氧化物铜矿石冶炼得来的纯铜，可用以铸钱及制作器物。 明 宋应星 《天工开物·铜》：“凡铜供世用，出山与出炉，止有赤铜。以炉甘石或倭铅参和，转色为黄铜；以砒霜等药制炼为白铜；矾、硝等药制炼为青铜；广锡参和为响铜；倭铅和写﹝泻﹞为铸铜。初质则一味红铜而已。”进口红铜的 价格 由于美国次级债危机带来的巨大的经济损失对红铜 价格 有一定影响在年底各大投行报告中显现，殃及金融 市场 ，破坏了经济发展前景。最新公布的相关经济数据中，当周领先指标已连续几周下滑；美国成屋销售数据减少1.2％，充分显示了美国需求的低迷；石油的连创新高，也拖累经济的发展速度。欧美股市连续大跌，尽管美元走软、黄金、石油叠创历史纪录，但基金却抓住了铜市基本面的薄弱，调转方向变为买铝抛铜的投机策略。自8月初始，LME铜库存总量持续性大幅增加，从16.7万吨边缘增至11月28日的18.7万吨，一月累计库存增量在2万吨以上，达到八个月来的最高位。供应压力不断增加， 现货 /3月铜升贴水从升水5美元滑向贴水50美元，足见 现货 的软弱无力。中国海关数据显示10月份中国进口铜下降至20.4万吨，较9月下降5.6％，进口大国——中国的需求滞缓，更引起了投机空头的大肆抛压。LME铜价从11月初的7750美元一路猛跌追打，铜价最低探至6445美元，是8个月以来的低点，一个月最大跌幅达到17％以上。进口红铜 价格 最新 行情 在外盘的打压影响下，从月初的64200元持续下跌，直至59400元，其中最低泻至55300元，最大跌幅接近15％，虽然沪铜 价格 一个月跌去10％，但其升水却越走越高。除贴水150-300元外，的第三个 交易 日起（11月5日）便出现平水-升水150元，此后持续走坚，直至11月29日升水高达1000元，但却仍难改变铜弱势走空的局面。
