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。

镀铝锌卷

镀铝锌卷组成结构:材料是镀层以锌为主并添加约11%铝3%镁和微量硅组成的新颖的耐腐蚀性镀膜钢板,其防锈功能为热渗镀锌板的15倍。由于镀敷附着量少却能实现相等的耐腐蚀性,又可省略后电镀或涂漆作业,且具有卓越的耐红锈性可代替不锈钢和铝板付诸使用,从而大大降低成本。镀铝锌卷的镀层硬度很高,具有耐严峻条件的加工密合性和卓越的耐损伤性,其切割端面初期会产生轻微红锈,但随后切割端面周围的镀膜成分开始溶解尤其是镁和硅的复合作用形成致密的保护膜数月后稳定的保护膜自动生成将完全覆盖切割端面,从而抑制端面部分拉伸部分甚至焊接部分都具有同样优秀的耐腐蚀性。热镀铝锌钢板的主要用途:                                                建筑业:民用和工业用建筑的屋顶、外墙、车库门、栅栏、百叶窗.                      家电业:烤箱、防爆带钢、空调通风系统外覆盖件、太阳能热水器、电器部件.汽车工业:汽车消音器、尾气管和催化转换器的防热罩、汽车车体底部零件、公路标志牌.工业仪表:电控柜、工业冷冻柜、自动售货机 .随着工业化的进步和发展,镀铝锌在工业及民用领域的用途越来越广泛。        以上是镀铝锌卷的介绍,更多信息请详见上海 有色金属 网。

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。

镀锌卷

镀锌卷,一种表面镀有锌的钢铁材料。镀锌卷是镀锌板的前身,利用设备把镀锌卷剪切成板而已,用叉车或者航吊把镀锌卷放到架子上然后通过设备的传送、压平、剪切而成。宽度都是标准宽度一米、一米二五、一米五三种,长度随意。镀锌卷的用途: 涂层钢板具有轻质、美观和良好的防腐蚀性能,又可直接加工,它给建筑业、造船业、车辆制造业、家具 行业 、电气 行业 等提供了一种新型原材料,起到了以钢代木、高效施工、节约能源、防止污染等良好效果。 使用镀锌钢板为基板的彩色涂层钢板,除有锌保护外,锌层上的有机涂层起了覆盖隔离作用,可防止钢板生锈,使用寿命比镀锌钢板更长,据介绍涂层钢板的使用寿命比镀锌钢板长50%。 但是,在不同的地区和不同的使用部位,采用相同镀锌量、同种涂料、相同涂层厚度的彩色涂层板,其使用寿命会有很大的不同。例如,在工业区或沿海地区,由于受到空气中二氧化硫气体或盐分的作用,腐蚀速度加快,使用寿命受到影响。在雨季,涂层长期受雨水浸湿、或者在日夜温差太大易结露的部位,都会较快地受到腐蚀,使用寿命均会降低。 用彩色涂层钢板制造的建筑物或厂房,经常受到雨水冲洗时使用寿命较长,否则,由于受二氧化硫气体、盐和灰尘的作用而影响使用。因此,在设计时,若屋顶的倾斜度越大,则越不容易积聚灰尘等污物,使用寿命越长;对于那些不受雨水经常冲洗的区域或部位,应定期用水冲洗。上海镀锌卷的 价格行情

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

2017-06-06 17:50:07

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。

镀锌钢卷

2017-06-06 17:50:06

镀锌钢卷,又称镀锌卷,一种镀锌卷状产品。镀锌卷,一种表面镀有锌的钢铁材料。镀锌卷是镀锌板的前身,利用设备把镀锌卷剪切成板而已,用叉车或者航吊把镀锌卷放到架子上然后通过设备的传送、压平、剪切而成。宽度都是标准宽度一米、一米二五、一米五三种,长度随意。镀锌卷的用途: 涂层钢板具有轻质、美观和良好的防腐蚀性能,又可直接加工,它给建筑业、造船业、车辆制造业、家具 行业 、电气 行业 等提供了一种新型原材料,起到了以钢代木、高效施工、节约能源、防止污染等良好效果。 使用镀锌钢板为基板的彩色涂层钢板,除有锌保护外,锌层上的有机涂层起了覆盖隔离作用,可防止钢板生锈,使用寿命比镀锌钢板更长,据介绍涂层钢板的使用寿命比镀锌钢板长50%。 但是,在不同的地区和不同的使用部位,采用相同镀锌量、同种涂料、相同涂层厚度的彩色涂层板,其使用寿命会有很大的不同。例如,在工业区或沿海地区,由于受到空气中二氧化硫气体或盐分的作用,腐蚀速度加快,使用寿命受到影响。在雨季,涂层长期受雨水浸湿、或者在日夜温差太大易结露的部位,都会较快地受到腐蚀,使用寿命均会降低。 用彩色涂层钢板制造的建筑物或厂房,经常受到雨水冲洗时使用寿命较长,否则,由于受二氧化硫气体、盐和灰尘的作用而影响使用。因此,在设计时,若屋顶的倾斜度越大,则越不容易积聚灰尘等污物,使用寿命越长;对于那些不受雨水经常冲洗的区域或部位,应定期用水冲洗。更多关于镀锌钢卷以及其他镀锌产品的信息,欢迎来上海 有色 网查询~~~

冷轧钢板的密度

2019-03-18 08:36:58

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

什么是卷焊钢管呢?卷焊钢管是指用钢带或钢板弯曲变形为圆形、方形等形状后再焊接成的、表面有接缝的钢管。焊接钢管生产工艺简单,生产效率高,品种规格多,设备资少,但一般强度低于无缝钢管。20世纪30年代以来,随着优质带钢连轧生产的迅速发展以及焊接和检验技术的进步,焊缝质量不断提高,焊接钢管的品种规格日益增多,并在越来越多的领域代替了无缝钢管。  按焊接方法不同可分为电弧焊管、高频或低频电阻焊管、气焊管、炉焊管、邦迪管等。按焊缝形状可分为直缝焊管和螺旋焊管。  电焊钢管用于石油钻采和机械制造业等。炉焊管可用作管等,大口径直缝焊管用于高压油气输送等;螺旋焊管用于油气输送、管桩、桥墩等。焊接钢管比无缝钢管成本低、生产效率高。直缝焊管生产工艺简单,生产效率高,成本低,发展较快。螺旋焊管的强度一般比直缝焊管高,能用较窄的坯料生产管径较大的焊管,还可以用同样宽度的坯料生产管径不同的焊管。但是与相同长度的直缝管相比,焊缝长度增加30~100%,而且生产速度较低。因此,较小口径的焊管大都采用直缝焊,大口径焊管则大多采用螺旋焊。   焊接钢管采用的坯料是钢板或带钢,因其焊接工艺不同而分为炉焊管、电焊(电阻焊)管和自动电弧焊管。因其焊接形式的不同分为直缝焊管和螺旋焊管两种。因其端部形状又分为圆形焊管和异型(方、扁等)焊管。焊管因其材质和用途不同而分为如下若干品种:  GB/T3091-1993(低压流体输送用镀锌焊接钢管)。主要用于输送水、煤气、空气、油和取暖热水或蒸汽等一般较低压力流体和其他用途管。其代表材质Q235A级钢。  GB/T3092-1993(低压流体输送用镀锌焊接钢管)。主要用于输送水、煤气、空气、油和取暖热水或蒸汽等一般较低压力流体和其它用途管。其代表材质为:Q235A级钢。  GB/T14291-1992(矿用流体输送焊接钢管)。主要用于矿山压风、排水、轴放瓦斯用直缝焊接钢管。其代表材质Q235A、B级钢。GB/T14980-1994(低压流体输送用大直径电焊钢管)。主要用于输送水、污水、煤气、空气、采暖蒸汽等低压流体和其它用途。其代表材质Q235A级钢。   GB/T12770-1991(机械结构用不锈钢焊接钢管)。主要用于机械、汽车、自行车、家具、宾馆和饭店装饰及其他机械部件与结构件。其代表材质0Cr13、1Cr17、00Cr19Ni11、1Cr18Ni9、0Cr18Ni11Nb等。   GB/T12771-1991(流体输送用不锈钢焊接钢管)。主要用于输送低压腐蚀性介质。代表材质为0Cr13、0Cr19Ni9、00Cr19Ni11、00Cr17、0Cr18Ni11Nb、0017Cr17Ni14Mo2等。  相关词  弯头,三通,螺旋钢管,大口径焊接管,双面埋弧焊焊接管  污水处理,输水,输气,热电,化工,电力,托辊 污水处理用管,大口径焊管  空调专用管,输气管,输水管,散热器用管  无缝钢管,无缝化管,热轧钢管,无缝扩管,无缝管  国标钢管,SY/T5037标准双面埋弧焊钢管,各种桩管  3PE防腐钢管,三油二布钢管,各种钢管镀锌业务,  基础的钢桩和构件、农业排灌、井壁套管、涵管、电力电信  储备库、储罐、球罐、锅炉、热交换器,螺旋钢管,无缝化管  各种型号螺旋焊管,螺旋管,打桩用管,供热管,输水管  焊接钢管,钢管生产厂家,直缝双面埋弧,Q235,Q345材质  无缝化管,输气管,工程用管,热轧管,双面埋弧焊接管  ASTM钢管,S355材质钢管,地铁用管,桩管  非型号钢管,扩管,大口径焊管,20#钢管  无缝钢管(无缝管)、直缝钢管(直缝焊管)、热扩钢管  无缝化管,电力管道钢管,施工钢管,锅炉配件钢管,  化工制冷钢管,空调专用钢管,螺旋钢管,直缝焊管,  大口径直缝双面埋弧焊钢管,直缝焊管,热烧管,  焊接管,无缝化管,排水钢管,输气钢管,国标钢管  无缝扩管,桩管,813螺旋焊接管  建筑用钢管,钢管厂,输送钢管,桩管,流体钢管,铁路钢管  720钢管/820钢管/920钢管/813钢管/1020钢管  输水工程钢管,广告牌用钢管,输送流体钢管  1820钢管/1120钢管/630钢管/530钢管/273钢管,螺旋钢管  双面大口径焊管,热轧钢管,工程用钢管,实用钢管  工程桩钢管,焊接螺旋缝钢管,直缝钢管,热轧无缝化钢管  管件,弯头,法兰,高压管件钢管,配套钢管  送水、煤气、空气、油和取暖蒸汽较低压力流体钢管  热减径钢管,热扩钢管,无缝扩钢管,大口径焊接钢管,螺旋缝钢管,  石油、天然气、煤气、水、蒸汽用钢管  基础桩钢管,输送流体钢管,高速路用钢管  焊管管材  焊管 不锈钢焊管 冷拔管 去内毛刺管 花纹管 考登钢管 油用管 机器用管 直缝焊管 变压器管 汽车用管 深井泵管 托辊管 公制焊管 电线套  管 吹氧焊管 一般焊管 焊管加工机械 自动电弧焊管 电焊管 炉焊管 螺旋焊管  焊管制品  电器设备 电气施工 健身器材 车辆车架 钢窗门 农机构件 热交换器 变压器散热管 栏栅 玩具 家具 电线套管 管 超市货架管  焊管原材料  钢带 钢板 带钢 热轧带钢 冷轧钢带 冷轧平板 薄板 原材料  焊管相关 钢材 不锈钢管 钢管 生铁 废钢 钢坯 宝钢 钢厂 硅钢 不锈钢 型钢 焊管贸易 焊管加工机械  焊管加工 开平 镀锌热轧 冷轧 焊管加工机械 直缝电阻焊 直缝埋弧焊 螺旋埋弧焊

镀锌板卷

2017-06-06 17:50:06

镀锌板卷,从字面上来看,就是卷装的镀锌板。其实镀锌板就是通过切割镀锌板卷而成的,我们可以根据需求,切割不同尺寸大小。镀锌板卷,一种表面镀有锌的钢铁材料。镀锌板卷是镀锌板的前身,利用设备把镀锌卷剪切成板而已,用叉车或者航吊把镀锌卷放到架子上然后通过设备的传送、压平、剪切而成。宽度都是标准宽度一米、一米二五、一米五三种,长度随意。镀锌板卷的用途: 涂层钢板具有轻质、美观和良好的防腐蚀性能,又可直接加工,它给建筑业、造船业、车辆制造业、家具 行业 、电气 行业 等提供了一种新型原材料,起到了以钢代木、高效施工、节约能源、防止污染等良好效果。 使用镀锌钢板为基板的彩色涂层钢板,除有锌保护外,锌层上的有机涂层起了覆盖隔离作用,可防止钢板生锈,使用寿命比镀锌钢板更长,据介绍涂层钢板的使用寿命比镀锌钢板长50%。 但是,在不同的地区和不同的使用部位,采用相同镀锌量、同种涂料、相同涂层厚度的彩色涂层板,其使用寿命会有很大的不同。例如,在工业区或沿海地区,由于受到空气中二氧化硫气体或盐分的作用,腐蚀速度加快,使用寿命受到影响。在雨季,涂层长期受雨水浸湿、或者在日夜温差太大易结露的部位,都会较快地受到腐蚀,使用寿命均会降低。 用彩色涂层钢板制造的建筑物或厂房,经常受到雨水冲洗时使用寿命较长,否则,由于受二氧化硫气体、盐和灰尘的作用而影响使用。因此,在设计时,若屋顶的倾斜度越大,则越不容易积聚灰尘等污物,使用寿命越长;对于那些不受雨水经常冲洗的区域或部位,应定期用水冲洗。镀锌板卷的 价格行情  价格 .jpg" />

酸洗板卷规格

2019-03-18 10:05:23

酸洗板是一个发展中的钢材品种,目前市场需求主要集中在汽车行业、压缩机行业、机械制造行业、零配加工行业、风机行业、摩托车行业、钢家具、五金配件、电柜货架及各种形状的冲压件等。随着技术进步,热轧酸洗板目前已涉及到家电、集装箱、电器控制柜等行业,其中使用热轧酸洗板代替冷板在一些行业发展很快。 1、汽车行业 热轧酸洗涂油板是汽车业需要的新钢种,其较好的表面质量、厚度公差、加工性能,可以替代车身覆盖件和以往用冷轧板生产的汽车零部件,由此降低原材料成本10%左右。随着经济的发展,汽车的生产也大幅增加,板材的使用量不断提高,国内汽车行业许多车型的零部件原设计要求使用热轧酸洗板,如:轿车的副车架、车轮轮辐、前后桥总成、卡车箱板、防护网、汽车大梁以及零配件等,由于国内热轧酸洗板的供应不足,汽车厂一般用冷板或热板代替或自行酸洗。 酸洗板卷规格2、农用车、摩托车行业 农用车制造业近年来发展迅速,其中山东市场的农用车行业发展较快,全年冷热板整体需求约为40万吨,很多农用车生产厂家愿意用酸洗板代替冷板以求降低成本,其中可“以热代冷”的部位主要是驾驶室内板、挡风板,所需规格主要为0.8—1.5×1000—1250mm等。 摩托车的轮毂也可以使用酸洗板。目前摩托车轮毂一般使用2.0mm冷板,由于成本高和厚规格的冷板较难采购,部分厂家一度改用热轧板,但热轧板又存在表面质量较差的问题,难以满足厂家的需要。使用酸洗板则可以满足用户对成本和质量的双重要求。 3、机械行业 热轧酸洗板主要用于纺织机械、矿山机械、风机以及一些通用机械等。比如制造家用冰箱、空调的压缩机壳体和上下盖,动力压缩机的压力容器和消声器,螺杆式空压机的底座等。其中家用冰箱、空调压缩机使用酸洗板最多,对酸洗板深冲性能要求较高,材质主要为SPHC、SPHD、SPHE、SAPH370,厚度范围在1.0-4.5mm,需求规格以2.0-3.5mm量最大,有关资料显示,今年上半年冰箱压缩机,空调压缩机所需热轧酸洗板分别为8万吨和13.5万吨。风机行业现主要使用冷轧板和热轧板,热轧酸洗板可以代替冷板用于制造鼓风机、通风机的叶轮、壳体、法兰、消声器、底座、平台等。 4、其他行业 其他行业应用主要有自行车零件、各种焊管、电气柜、高速公路护栏、超市货架、仓库货架、栅栏、热水器内胆、制桶、铁梯以及各种形状的冲压件。随着经济的不断发展,零配加工遍布各行业,加工厂如雨后春笋迅速发展,对板材的需求大大增加,同时也增加了热轧酸洗板潜在需求量。 三、酸洗板市场前景 酸洗板是以优质热轧薄板为原料,经酸洗机组去除氧化层,切边,精整后,表面质量和使用要求(主要是冷弯成型或冲压性能)介于热轧板和冷轧板之间的中间产品,是部分热轧板和冷轧板理想的替代产品。与热轧板相比,酸洗板的优势主要在于:1)表面质量好,由于热轧酸洗板去除了表面氧化铁皮,提高了钢材的表面质量,便于焊接、涂油和上漆。2)尺寸精度高,平整后,可使板型发生一定变化,从而减少不平度的偏差。3)提高了表面光洁度,增强了外观效果。4)能减少用户分散酸洗造成的环境污染。与冷轧板相比,酸洗板的优势在于在保证表面质量使用要求的前提下,使用户有效的降低采购成本。目前,许多企业对钢材的高性能、低成本提出越来越高的要求。随着轧钢工艺技术不断进步,热轧薄板的性能正向冷轧板接近,使“以热代冷”在技术上得以实现。可以说,酸洗板是介于冷轧板和热轧板之间的性能价格比比较高的一种产品,有着良好的市场发展前景。但是从目前看,酸洗板在我国各个行业的使用才刚刚起步,专业的酸洗板生产从2001年9月宝钢酸洗生产线投产开始。 酸洗板市场主要体现在以下四个方面:替代冷轧、替代热轧、替代进口和替代小酸洗。其中替代进口和小酸洗实际上是已有的市场,市场有限也不可能完全替代。而随着汽车、机械、轻工等行业的快速发展,企业面临这市场竞争带来的巨大的压力,对产品成本和产品质量要求日益提高,酸洗板以其较高的性价比完全替代部分冷板和热板,必将逐渐为用户所认可。在钢材的深加工加工过程中,需对其表面进行酸洗除锈处理。常用的酸洗液为和硫酸,现大多数企业已不再使用硫酸,改用。 钢材经酸洗后,会产生大量的酸洗废液。酸洗废液的组成主要是氯化氢、氯化亚铁和水等少量杂质。其含量随酸洗工艺、操作温度、钢材品种和规格不同而异,一般含氯化亚铁10~20%,氯化氢 3~10%。 酸洗废液按国家环保要求是不能直接排放的,传统的处理方法是采用焙烧回收法和中和法。焙烧回收法投资巨大,一般企业无法接受。中和法是现有钢铁企业普遍采用的方法,但其存在的缺点也较突出,一方面要消耗大量的碱性药剂(如烧碱、石灰等),处理成本十分昂贵,另一方面又会生成大量难以处置的含铁污泥,对环境造成变相二次污染。 针对钢铁行业酸洗废水的特点,科研单位做了大量的研究开发工作,成功地开发了一套钢材酸洗废液处理系统。该系统为全封闭系统,达到零排放标准,回收和氯化亚铁。如能进一步深加工可生产液体、聚合等水处理絮凝剂产品。 铁盐絮凝剂是目前经济高效的废水处理絮凝剂其独有的脱色能力,适用于染料、染料中间体及印染行业的污水处理。能简化水处理工艺,缩短水处理周期,降低水处理成本,提高处理水质十分有效。对各类电镀废水有明显的处理效果,对废水中各种重金属离子的去除率接近100%。

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)。
