冷轧镀锌

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。

热镀锌扁钢,即指采用热浸新工艺方法,在扁钢表面镀锌,从而达到防腐目的的一种镀锌钢材产品。扁钢,是指宽12-300mm、厚4-60mm、截面为长方形并稍带纯边的钢材。扁钢可以是成品钢材,也可以做焊管的坯料和叠轧薄板用的薄板坯。型钢是钢材四大品种(板、管、型、丝 )之一。根据断面形状,型钢分简单断面型钢和复杂断面型钢(型钢)。前者指方钢、圆钢、扁钢、角钢、六角钢等;后者指工字钢、槽钢、钢轨、窗框钢、弯曲型钢等。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。热镀锌板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。热镀锌的优点:处理费用低;持久耐用;可靠性好;镀层的韧性强;全面性保护;省时省力。扁钢尺寸规格表 热镀锌扁钢作为成材可用于制箍铁、工具及机械零件,建筑上用作房架结构件、扶梯。 

冷轧

2017-07-04 14:41:18

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.""

不锈钢带

2019-03-18 11:00:17

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。

冷轧知识介绍

2019-01-11 10:52:00

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。

冷轧钢板标准

2019-03-18 08:36:58

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

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。

冷轧钢板的密度

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

冷轧板的用途

2019-03-18 10:05:23

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)。

热浸镀铝锌硅熔液对钢带的腐蚀性的特点

2018-12-29 13:37:12

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

2019-01-09 09:34:20

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。

为什么不锈钢也会"生锈"为什么有的不锈钢带磁性?

2018-12-12 09:41:29

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。

基于辊缝动态摩擦方程的铝板冷轧机垂振机理分析

2019-01-11 09:43:18

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。
