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)。

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

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。

废电路板提金及再利用技术大全

2018-12-05 13:53:44

废电路板的回收是一个新兴行业。随着大量家用电器的报废,废电路板的数量越来越大,其回收利用价值也引起众多投资者关注,成为很有发展前途的产业。 废电路板的成分复杂,回收处理难度大,且电路板在生产过程中加入了大量的有机物质,在废电路板的回收处理过程中稍有不慎就可能对环境产生严重的污染。目前,我国废电路板的回收处理技术还比较落后,开发先进的废电路板处理技术已成为众多技术人员研究的对象。本文拟就目前的废电路板回收处理技术作一介绍和评析。 一、废电路板的组成 废电路板包括废覆铜板(CCL)、废印刷线路板(PCB)、带有集成电路和电子器件的印刷线路板卡(一般称为废电路板)。1.废覆铜板 覆铜板是生产印刷线路板的原材料,主要由基板、铜箔、粘合剂组成。基板的主要材料是合成树脂和增强材料,其中合成树脂主要有酚醛树脂、环氧树脂、聚四氟乙烯等,增强材料一般有纸质和布质两种。 基板的表面是铜箔,铜箔采用机械加工和电积法生产,目前以电积法生产为主,铜箔厚度一般为18μm、25μm、35μm、70μm、和105μm。铜箔用粘合剂牢固地粘覆在基板上,就形成了覆铜板。 目前我国大量使用的覆铜板有酚醛纸质覆铜板、环氧纸质覆铜板、环氧玻璃布覆铜板、聚四氟乙烯覆铜板、聚酰亚胺柔性覆铜板,其中中档以上的民用电器、仪器仪表采用环氧(纸质或玻璃布)覆铜板,用量较大。中低档次的民用电器多用酚醛纸质的覆铜板。 废覆铜板是在生产过程中产生的残次品、边角料,由于表面有压制的铜箔而呈现黄色,一般称之为黄板。废覆铜板含铜量不一,低的约15%,高的可达70%以上,是一种回收铜的重要资源。2. 废印刷线路板 印刷线路板简称PCB。通常把在绝缘材上按预订设计制成印制线路、印制原件或两者组合而成的导电图形称之为印制电路,把在绝缘基材上提供元器件之间电气连接的导电图形称之为印制线路。印制电路或印制线路的成品板即称为印刷线路板。 印刷线路板主要用于给集成电路等各种电子元器件固定装配提供支撑、实现集成电路等各种电子元器件之间的布线和电气连接或电绝缘等,同时为自动锡焊提供阻焊图形,为元器件插装、检查、维修提供识别字符和图形。 我们能见到的电子设备几乎都有PCB,如计算器、电脑、通讯电子设备、军用武器系统等,只要有集成电路等电子元器件,它们之间的电气互连都要用到 PCB。常见的电脑板卡基本上是环氧树脂玻璃布基双面印制线路板,其中一面是插装元件,另一面为元件脚焊接面,焊点一般很有规则。 印刷线路板在生产过程中产生的残次品就是我们常说的废印刷线路板,因主要呈绿色,因此又称为绿板。在制作印刷线路板时,尽管一部分铜已经被腐蚀掉,而使印刷线路板的含铜量比覆铜板要低,但是印刷线路板仍然是回收铜的资源之一。3. 废电路板卡 废电路板卡主要来自各种报废的电器,种类很多,常见的有绿板和黄板,其中绿板主要是从废电视机、电脑、通讯设备中拆解下来的,价值较高;黄板则主要是从录音机、音响设备、洗衣机、空调中拆解下来的,价值较低。 废电路板卡的成分比较复杂,除印刷线路板之外,还含有集成电路和各种电子元器件,主要成分是二氧化硅、铜箔、铅、锡、铁微量的贵金属和塑料、树脂、油漆等有机物质,因此处理难度比废覆铜板、废印刷线路板的处理难度大。

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

电工用冷轧硅钢薄板

2018-05-10 17:56:11

(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。

跟着信息社会的到来,电子智能标签在产品防伪、防盗及证卡的使用和办理方面现已逐步构成潮流。跟着使用数量的剧增,电子智能标签产品的出产厂、线如漫山遍野般喷涌而出。据开端预算,目前国内电子智能标签产品出产进程中年排放的化学蚀刻废液达几十万吨,与环境、资源的对立也已日益暴露。   在电子智能标签出产进程中,选用铝加工职业中电化学工艺发作的废渣——白泥,对覆膜铝基的化学蚀刻工艺发作的废液进行处理,并在处理进程中提取金属及相应化工产品的工艺技能,是“以废治废”工程技能使用上的又一模范。   在该项技能诞生之前,职业界对电子智能标签出产中产排的化学蚀刻工艺废液,只能进简略地酸、碱中和后进行排放或简略地提取,造成了对天然环境的污染和资源的糟蹋。   白泥是铝职业电化学处理时发作的工业废渣,主体成分是Al、Si、Ca、Mg和絮凝剂组成的多种化合物之混成。化学蚀刻废液开发使用新技能,分为“简明开发”工艺和“精密开发”工艺两大区块。使用简明处理工艺能够从化学蚀刻废液中提取氧化铜CuO,再把投入的废渣白泥和含有AlCl3的溶液,转化成为产量相对高的氢氧化铝凝胶Al(OH)3.nH2O,较后从处理尾液中收回工业食盐氯化钠NaCl;选用精密开发工艺,仍以对铝工业废渣白泥的使用为关键,从化学蚀刻废液中提取金属铜Cu、氧化亚铜Cu2O、氧化铜CuO、六水AlCl3?6 H2O、氢氧化铝凝胶Al(OH)3.nH2O和工艺尾液收回工业食盐氯化钠NaCl。   一、化学蚀刻废液“以废治废”简明处理工艺   1. 提取氧化铜   使用废渣“白泥”分化废液中的:将废液导入有加热和拌和功用的耐酸反响釜中,过量增加铝业电化学处理废渣白泥,搅匀而且加热到80~90℃,再在恒温中适度搅动反响40~60min。液相中的CuCl2与白泥中占比为80%~84%的氢氧化铝Al(OH)3发作复分化反响,生成孔雀蓝色絮状的氢氧化铜Cu(OH)2。   3CuCl2+2Al(OH)3=3Cu(OH)2+2AlCl3   反响完成后操控液相的pH≤3,只要在这个前提下,反响生成的氢氧化铜Cu (OH)2才干彻底地溶解于液相之中。   固液别离:把反响完成后的物料进行固液别离,除掉反响后剩下的白泥和其他未能反响或不能溶于液相的固体剩下物质。   暂提氢氧化铜和氢氧化铝混成物:把经固液别离得到的淋清液,于常温条件下,适度地搅动中,慢慢地参加预配浓度为10%~15%的NaOH溶液至全体溶液的pH为5.5~6时止,溶液中的AlCl3当即复分化为氢氧化铝Al(OH)3白色絮状物。   AlCl3+3NaOH=Al(OH)3+3NaCl   在pH为5.5~6的溶液中,本来现已溶解于液相中的氢氧化铜Cu(OH)2,也以天蓝色的絮状物分出。   转化氧化铜和氧化铝混合物:经固液别离提取氢氧化铝和氢氧化铜相混合的固相后,再于300~400℃的温度中煅烧45~60 min, 氢氧化铜Cu(OH)2转化为氧化铜CuO;氢氧化铝Al(OH)3也一起转化为克西晶型的氧化铝Al2O3。   Cu(OH)2 = CuO+H2O   2 Al(OH)3=x-Al2O3+3 H2O   提取氧化铜:把现已转化为氧化铜和氧化铝的混合物料,置入有加热功用的反响釜中,再过量地参加预配浓度为22%~26%的溶液。在适度地搅动中将物料加热到80~105℃后,再恒温反响45~60min,氧化铝Al2O3现已转化为铝酸钠NaAlO2而进入液相中;氧化铜CuO仍以本来面貌存在于混合物猜中。   Al2O3+2NaOH=2 NaAlO2+ H2O   上面的反响完成后,再经固液别离出固相物氧化铜,将固相物通过2~3道次水洗后,在200~300℃的温度中烘干,得产品氧化铜CuO。   2. 提取氢氧化铝凝胶   将固液别离出的溶液在常温文搅动中,慢慢地参加浓度为8%~15%的HCl,至溶液pH为4.5~5时止。在这样的条件中,液相内的铝酸钠NaAlO2当即水解成皎白的氢氧化铝凝胶Al(OH)3.nH2O并以絮状物分出。   NaAlO2+HCl+ (n+1)H2O= Al(OH)3.nH2O+ NaCl   水解反响完成后进行固液别离,并彻底水洗别离后获得固相物质。再于100~200℃温度中烘干固相物质表面吸附的水分后,终得氢氧化铝凝胶Al(OH)3.nH2O。   3. 收回氯化钠   将提取氧化铜和提取氢氧化铝凝胶后剩下的溶液兼并,以加热或天然蒸腾方法浓缩至液内的溶质过饱和状况时,再冷凝提取氯化钠NaCl结晶体。   二、化学蚀刻废液“以废治废”精密开发工艺   1. 提取金属铜   预调蚀刻废液的电化学功能   电子智能标签化学蚀刻工艺中,产排的废液的电导和电化学处理时溶液的涣散才能均不如专门湿法冶金提铜的电解液那样。所以在电解提铜前,必须向废液中增加2%~3%的工业硫酸H2SO4,以改进待处理废液的电化学功能。   从废液中电解提铜   A工艺参数   阳极材料:石墨   阴极材料:0.15~0.2mm厚的紫铜板   对偶电极间隔:80~100mm   电源设备:半波整流脉动直流电源(设备的功率按负荷巨细决议)   槽电压:4~6V   阳极电流密度:3~6A/dm2   槽液工艺温度:≤50℃   B. 操作方法   把待处理的化学蚀刻废液注入电解池内至80%的池容量后,按工艺参数的要求放入阴极和阳极,接通电解电源并当即调整工艺电流契合参数要求。跟着工艺历时的叠加,在电流的热效应中电解池内液温逐渐升高,溶液的电导也会随液温的升高而增大,所以在平等槽电压中,工艺电流跟着液温的增高而增高。操作人员应该依据电解池内溶液温度升高而导致工艺电流增高的状况,及时调整槽电压,使阴极电流密度操控在工艺参数要求的范围内。   当电解提取金属铜的工艺发展到必定程度时,跟着电解池溶液中的二价铜离子Cu2+因不断地在阴极界面上复原成金属铜,而削减到必定程度时,溶液也从开端处理时的深绿或墨绿色变为浅绿色,这时能够酌情终断电解提铜的工艺操作。取出阴极并及时洗刷和烘干后,再通过≥1 100℃的熔化铸锭工艺,得到产品电解铜锭。   2. 收回氧化亚铜   电解提铜的进程中,现已在阴极复原生成的金属铜表面部位,又被紧邻阴极界面的水分子在阴极电场力撕离崩溃的电极界面的反响中 (水分子电极界面电离理论),而生成的氢离子H+效果下氧化而成一价铜离子Cu+。   2Cu+ 2H+=2Cu ++H2   重生的一价铜离子Cu+又当即与水分子被阴极界面电场力电离时一起生成的氢氧根离子结合,生成了氧化亚铜Cu2O沉附于阴极表面,跟着慢慢地沉附堆集构成了树枝状的相似铜粉色彩的氧化亚铜Cu2O。   2Cu ++2OH-=Cu2O+H2O   当阴极界面上的氧化亚铜生成并积累到必定数量时,这些铜粉色彩的物质从阴极界面脱落后沉入电解池底,可由事前现已设置在池底的耐酸化纤丝网接取,得产品氧化亚铜Cu2O。   在废液电解处理进程中,假如不想收回氧化亚铜时,只要在电解进程中适时地增加足量的于池液中,现已生成的氧化亚铜在有足量存在的溶液中从头又被彻底氧化,成为CuCl2溶入池液中又成为新的电解提铜的质料物质。   Cu2O+ H2O2+4HCl =2CuCl2+ 3H2O   3. 收回六水   通过了电解提取工艺处理后的剩下溶液中含有很多的,将这些剩液弄清过滤后,导入浓缩池进行加热或天然蒸腾的浓缩至过饱和状况时,在缓慢冷凝进程中分出六水结晶AlCl3?6 H2O。将分出物捞出而且天然枯燥,待表面浮水蒸腾后,得产品六水。   经国内工艺3后,提取氧化铜、提取氢氧化铝凝胶、收回氯化钠等工艺进程同简明处理工艺根本相同。   对铝的化学蚀刻废液进行“以废治废”的精密提取进程,是三废管理的较高阶段。这是一种工艺逻辑性比较强的“变废为宝”新理念。连续这种三废管理新思想,会对职业界的相关从业者建立新的三废处理思想有所启迪,进步三废处理和综合使用的科学合理性,防止在三废管理中发作资源使用方面的再次糟蹋,构成环境、资源和经济上的更大效益。

废杂铝的再生,废杂铝如何回收处理?

2018-07-20 17:39:20

废杂铝的回收处理不仅可以节省资源,而且可以减少能源消耗,并促进环境保护。目前,我国的再生铝产能总体规模已突破1000万吨,废杂铝的会收录一直在飞速增长,铝的再生资源在整个铝工业原料中的比重也越来越大。那废杂铝料如何进行再生,废杂铝如何进行回收处理?下面上海有色网小编带你了解有色金属废杂铝回收处理的四个过程: (1) 分类对 废杂铝 的分类是至关重要的一步。分类是对废杂铝进行初级分类,分级堆放,如分为纯铝、变形铝合金、铸造铝合金、混合料等。对于一些连有其他金属的废铝制品,也应去除其他有色金属零部件,再进行清洗、破碎、磁选、烘干等工序制成废铝料。对于轻薄松散的片状废旧铝件,如汽车上的锁紧臂、速度齿轮轴套以及铝屑等,要用液压金属打包机打压成包。对于导线类废铝,一般可采用机械研磨或剪切剥离、加热剥离、化学剥离等措施去除包皮,然后将铝线绕成卷。(2) 配料对废铝进行初级的分类后,就可以根据废铝料的分类及质量状况,遵循再生产品的技术要求,选用搭配并计算出各类料的用量。配料时应考虑金属的氧化烧损程度,硅、镁的氧化烧损较其他合金元素要大,各种合金元素的烧损率应事先通过实验确定之。废铝料的物理规格及表面洁净度将直接影响到再生成品质量及金属实收率,除油不干净的废铝,最高将有 20 %的有效成分进入熔渣。(3) 再生变形铝合金用废铝合金可生产的变形铝合金有3003 、3105 、3004 、3005 、5050 等,其中最主要的再生铝合金是3105合金。在加工过程中,必要时需加入一部分原生铝锭来保证合金材料的化学成分符合技术要求及压力加工的工艺需要。(4) 再生铸造铝合金废铝料只有一小部分再生为 变形铝合金 ,约 1/4 再生成炼钢用的脱氧剂,大部分用于再生铸造用铝合金。美、日等国广泛应用的压铸铝合金 A380 、 ADCl0 等基本上是用废铝再生。最近几年,稀土合金再生铝工艺有望使废铝回收冶炼业的环境污染问题得到完全解决,该工艺充分运用稀土元素与铝熔体相互作用的特性,发挥稀土元素对铝熔体的精炼净化和变质功能,能够实现对铝熔体的净化、精炼及变质的一体化处置,不止简洁高效,而且能够有效地改善再生铝的冶金质量。处理的全程中均不会产生有害的废气和其他副产品。

废黄铜

2017-06-06 17:50:00

废黄铜(Refinery Brass)是指含铜量至少61.3%,含铁量小于5%,包括黄铜与青铜的块料及其边角料及这些合金的混合废料。不含绝缘线、磨屑料及非金属。    废黄铜按其来源有两类。一类是新废黄铜,它是黄铜工业生产过程中产生的废料。另一类是旧废黄铜,它是使用后被废弃的物品。黄铜和黄铜基材料,不论处于裸露状态,还是被包在最终产品里,在产品寿命周期的各个阶段都可回收再生。一般来说,用于再生的废黄铜中新废黄铜占一半以上。        实际上所有的废黄铜都可以再生。再生工艺很简单。首先把收集的废黄铜进行分拣。没有受污染的废黄铜或成分相同的黄铜合金,可以回炉熔化后直接利用;被严重污染的废黄铜要进一步精炼处理去除杂质;对于相互混杂的铜合金废料,则需熔化后进行成分调整。通过这样的再生处理,黄铜的物理和化学性质不受损害,使它得到完全的更 新。        黄铜的用途:    黄铜是主要由铜和锌形成的合金,用途甚广,其性质取决于铜和锌的比例。含铜达63%以上的黄铜,可以冷加工,可以退火,有延展性;而含铜较少、含锌较多的合金,则应热加工,强度较高。    黄铜以锌作主要添加元素的铜合金﹐具有美观的黄色﹐统称黄铜。铜锌二元合金称普通黄铜或称简单黄铜。三元以上的黄铜称特殊黄铜或称复杂黄铜。含锌低於36%的黄铜合金由固溶体组成﹐具有良好的冷加工性能﹐如含锌30%的黄铜常用来制作弹壳﹐俗称弹壳黄铜或七三黄铜。含锌在36~42%之间的黄铜合金由和固溶体组成﹐其中最常用的是含锌40%的六四黄铜。为了改善普通黄铜的性能﹐常添加其他元素﹐如铝﹑镍﹑锰﹑锡﹑硅﹑铅等。铝能提高黄铜的强度﹑硬度和耐蚀性﹐但使塑性降低﹐适合作海轮冷凝管及其他耐蚀零件。锡能提高黄铜的强度和对海水的耐腐性﹐故称海军黄铜﹐用作船舶热工设备和螺旋桨等。铅能改善黄铜的切削性能﹔这种易切削黄铜常用作钟表零件。黄铜铸件常用来制作阀门和管道配件等。    在所有金属中,铜的再生性能最好。废黄铜是铜工业的一个重要原料来源。在 1997年世界铜消费量中,有37%来自再生铜。        更多关于废黄铜的资讯,请登录上海有色网查询。

废红铜的价格

2017-06-06 17:50:06

今日废红铜的 价格 截至北京时间今日零时,伦敦 金属交易 所(LME)期铜合约在场内 交易 中最新报8310美元/吨,涨120点,而电子盘 交易 中则大涨325美元,报8415美元/吨;诸如铝、镍、锡、锌等 有色金属期货 品种也出现不同程度的上扬。而纽约 现货 黄金最新报689美元/盎司,涨9.4点。与此同时,今日废红铜的 价格 再纽约商品 交易 所的大背景下,轻质原油 期货价格 最新报69.64美元,再度逼近70美元关口。在北京时间下午15点左右,国际商品 市场 曾经出现了一次幅度巨大的回调,当日 金属期货 以及原油 期货市场 普遍呈现抛售局面。LME废红铜的 价格 电子盘中跌穿8000美元大关,最低到达7825美元/吨,跌幅达到了惊人的715美元/吨。此外,期锌电子盘中跌破3000美元,纽约 现货 黄金700美元关口也宣告失守。业内人士认为美元的复苏走强是导致国际商品 市场 走弱的主要原因,美元的走强使得很多跟风盘对牛市 行情 产生了怀疑态度,从而产生恐慌性抛盘。但业内人士表示国际基金短期的获利回吐并非大部分人想像的那么简单,基金赖以生存的是巨大的利润回报,在今日废红铜的 价格 目前快速拉升的背景下很难再找到一个可以让基金获取利润的对手,唯一的办法就是平仓了结,进行调整。关于今日废红铜的 价格 ,首先了解一下紫铜:红铜是什么?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。红铜是什么特性:红铜具有高纯度,组织细密,含氧量极低。无气孔、沙眼、疏松,导电性能极佳,电蚀出的模具表面精度高,经热处理工艺,电极无方向性,适合精打,细打,具有良好的热电道性、加工性、延展性、防蚀性及耐候性等。废红铜的 价格 由其用途决定:可应用于电器、蒸溜建筑及化学工业,尤其端子印刷电器路板,电线遮蔽用铜带、气垫,汇流排端子。电磁开关、笔筒、屋根板等。红铜的密度:8.96g/(cm) 红铜的比重:8.89g/(mm) Cu≥99.95% O<003 电导率≥57ms/m 硬度≥85.2HV红铜是什么得名的?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。中国红铜加工材按成分可分为:普通红铜(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。红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。红铜在大气、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,红铜有良好的焊接性,可经冷、热塑性加工制成各种半成品和成品。20世纪70年代,红铜的 产量 超过了其他各类铜合金的总 产量 。废红铜的性质:红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 。废红铜的 价格 也水涨船高。综上所述,今日废红铜的 价格市场 尤其是 金属市场 的 宏观 背景仍然表现良好,特别是最近欧美地区的OECD指标、制造业指数、采购经理人指数增长强劲,这有利于商品 市场 以及废红铜的 价格 继续运行在高位。  

预滚涂板与喷涂板的区别

2019-02-28 11:46:07

二者的首要差异在于涂漆的阶段和工艺不同。   预滚涂是在基材仍是卷状时,在流水线上经过酸洗、矫相等程序,依据要求的漆层厚度,有电脑操控,经过几烤几烘,在相对密闭的空间内完结。滚涂后就是一卷卷带漆层的铝板。如使用时依据尺度直接裁剪和折弯,即可施工。     喷涂是在依据施工图纸断定的规格,对不带漆层的铝板裁剪和折弯成型后,再用喷上漆。     关于商场上的金属铝幕墙来说,种类许多。就涂漆层面来说,首要分喷涂、预滚涂及电镀等。综合功能比较,是喷涂远低于预滚涂,预滚涂在部分指标上低于电镀;在空间上,国产首要是喷涂,国外已是预滚涂产品占主流了,电镀产品在国外也早有人用了。国内和国外为何会形成这种“代”差呢?首要原因有以下二个方面:     资金、技能和设备。     国内幕墙厂商多,规划小,鱼龙混杂,不乏作坊式出产。关于数十亿美元一条的滚涂出产线和严厉的技能配套要求来说,明显还不具备条件。     建筑理念和商场观念要素等。也就是人祸。建筑是千秋大业仅仅嘴上说说罢了,我们只管眼前利益而不讲久远效益。(一个比如是上海陆家嘴的一楼盘,十几如果平方的价格外墙仅用铝塑板贴了拉倒,降低成本啊,成果成交廖廖)。业主外行,出产商就都拼报价,偷工减料,压低薪酬,献身质量,技能研制和升级换代就更是无稽之谈了,成果就是整个职业留步不前。     1***H**——指含99%纯铝的纯铝板     2***H**——指铝铜合金     3***H**——指铝锰合金     4***H**——铝硅合金     5***H**——铝镁合金,可用做船板或防弹铝板.     H1*——静态煺火(也叫最终煺火);     H2*——动态煺火(继续出产线上煺火,也叫中间煺火);     H3*——内部应力处理;     H4*——上面三种只需涂层后都是4.     H*2、H*4、H*6——后边的数字是硬度比值。数字越小,硬度越小;反之越大。     普基铝镁板是预滚涂板,不是喷涂板AA5754H44基材,2.0mm厚度的产品各项功能已卓而不群,选用接连三涂三烤工艺,抗老化、不掉漆,涂层氟碳树脂含量达70%以上,加强筋选用镀锌钢板,柔性衔接,强度高,不变形。删去

镀锌格栅板

2017-06-06 17:50:04

镀锌格栅板,即格栅板生产出来以后,要进行防锈处理。有热镀锌(热浸镀锌)和电镀锌(冷镀锌)2种。格栅板是钢格板的别名,是用扁钢按照一定的间距和横杆进行交叉排列,并且焊接成中间带有方形格子的一种钢铁制品,主要用来做水沟盖板,钢结构平台板,钢梯的踏步板等.横杆一般采用经过扭绞的方钢作为一种新材料、新产品正得到日益广泛的应用,其较多的优越性能及良好的性能 价格 比显示了其应用的前景。格栅板的制作方式:有机器压焊和手工制作两种.机器压焊使用高压电阻压焊机,机械手自动将横杆横放在均匀排列的扁钢上,通过强大的电焊功率和液压力将横杆压焊入扁钢内,从而可以得到焊点坚固,稳定性和强度极高的高品质格栅板.手工制作的格栅板是先在扁钢上冲孔,然后将横杆放入孔中点焊,横杆与扁钢会存在空隙,而且不可能每个接触点都进行焊接,因此焊接不牢固,强度有所降低.   在冶金、矿山、石油、电力与工业领域以及一些民用领域中,格栅板作为一种新型建材正得到日益广泛的应用。所谓新材料,其实在国外已有几十年以上的历史,不过在中国得到广泛应用也只是近10年的事。但就象铝合金门窗一样,与传统材料相比,人们习惯上还是将其称作新材料。格栅板特点及用途特点: 1.高强度,轻结构:牢固的网格压焊结构使其具有高承载,结构轻2.便于吊装等特点3.外形美观,经久耐用:热浸锌表面处理使其具有相当好的防腐能力4.表面光泽美观5.通风、采光、散热、防爆、防滑性能好;防积污物用途:广泛应用于石油化工、电厂、水厂、污水处理厂、市政工程、环卫工程等领域的平台、走道、栈桥、沟盖、井盖、梯子、围栏、护栏等。

将镍及镍合金板经熔炼、铸锭、平辊轧制加工成单张或成卷加工材的过程。镍及镍合金具有熔点高、热稳定性好、耐蚀、强度高、加工性能良好等优点。镍合金板带材广泛用于精密仪表、电子、医疗器械、航天航空等工业部门。热轧板厚度5~20mm,冷轧板厚度0.5~10mm,宽度不大于1000mm;带材厚度0.05~1.5mm,宽度一般不大于300mm。镍及镍合金板带的基本生产工艺流程如下:熔铸 镍及镍合金板熔体能吸收大量气体,发生强烈的氧化。一般采用感应电炉熔炼、熔体表面覆盖玻璃,用木炭、锰、硅、镁、钛等脱氧。高纯度的镍及镍合金板采用真空熔炼。蒙乃尔(NCu28—2.5—1.5)等合金采用电渣熔炼。熔炼温度在1450~1560℃之间,随合金而异。通常扁锭用生铁模铸造(见生铁模铸锭)或半连续铸造(见半连续铸锭)。锭重在30~400kg范围内。铸锭表面的夹杂、冷隔等缺陷应进行清理.热轧 镍及镍合金板的高温塑性良好,变形抗力较高,加热温度在1050~1250℃范围内,以电炉加热为宜。若使用煤气炉,则煤气含硫量必须严格控制,以免造成热脆。重400kg厚度为200mm的镍锭,经11个道次热轧至10mm厚。有时热轧前先行锻造,以改善内部组织.酸洗 镍及镍合金板铣面(见有色金属合金锭坯铣面)时易粘刀具,故对热轧板坯常用酸洗的方法除去表层的氧化物。酸洗采用硫酸与硝酸的混合酸,或单独的硝酸。为提高酸洗效果,酸洗前先以小压下量冷轧一道,使延伸小于基体的氧化层被破碎,以利于同酸反应.冷轧 厚度5.0~13.5mm的热轧坯,需经多次反复冷轧和退火,到达成品厚度。两次退火间的压下率可达70%~85%。冷轧常用四辊轧机。高强度的镍合金薄带采用12辊或20辊轧机精轧。冷轧时应充分润滑和冷却,以防粘辊,影响表面质量.退火 退火分中间退火和成品退火。中间退火的目的是消除冷轧造成的加工硬化;成品退火则为了控制成品性能。镍和镍合金板完全退火的温度在570~850IC间,取决于合金成分和制品厚度。成卷薄带退火时易于粘结,故退火前应重卷。因镍合金板的氧化皮较难清除,故常用钟罩式真空炉进行退火。镍铝、镍钛和其他复杂镍合金板可通过固溶/时效处理实现沉淀硬化,以提高强度.

热镀锌格栅板

2017-06-06 17:50:06

热镀锌格栅板,又称热镀锌钢格板,是用扁钢按照一定的间距和横杆进行交叉排列,并且焊接成中间带有方形格子的一种钢铁制品,主要用来做水沟盖板,钢结构平台板,钢梯的踏步板等。横杆一般采用经过扭绞的方钢作为一种新材料、新产品正得到日益广泛的应用,其较多的优越性能及良好的性能 价格 比显示了其应用的前景。热镀锌格栅板一般采用碳钢制作,外表热镀锌,可以起到防止氧化的作用,也可以采用不锈钢制作。格栅板具有通风,采光,散热,防滑,防爆等性能。格栅板的分类:   按焊接方式,可分为:压焊型、相嵌型、穿锁型和穿焊型。   按按其负载扁钢侧表面的形状,可分为:平面型、齿型和“工”字型等。   按其用途可分为:一般用途钢格栅板和专门用途的钢格栅板如:地沟盖板、踏步板等等。   按材料分为:不锈钢钢格栅板和碳钢钢格栅板。热镀锌格栅板的特点:高强度,轻结构;防腐能力强,经久耐用;外形美观,表面亮泽;便于安装他折卸;通风,采光,散热,防滑,防爆性好;不积污物,不积雨雪,不积水,自清洁,易于维护。热镀锌格栅板的应用:广泛应用于石油化工,电力,自来水,污水处理,港口码头,建筑修饰,造船,自走式停车场,市政工程,环卫工程等领域平台,走道,栈桥,沟盖,井盖,梯子,围栏等。   格栅板的制作方式:有机器压焊和手工制作两种。机器压焊使用高压电阻压焊机,机械手自动将横杆横放在均匀排列的扁钢上,通过强大的电焊功率和液压力将横杆压焊入扁钢内,从而可以得到焊点坚固,稳定性和强度极高的高品质格栅板,手工制作的格栅板是先在扁钢上冲孔,然后将横杆放入孔中点焊,横杆与扁钢会存在空隙,而且不可能每个接触点都进行焊接,因此焊接不牢固,强度有所降低。   在冶金、矿山、石油、电力与工业领域以及一些民用领域中,热镀锌格栅板作为一种新型建材正得到日益广泛的应用。所谓新材料,其实在国外已有几十年以上的历史,不过在中国得到广泛应用也只是近10年的事。所以热镀锌格栅板在中国 市场 的前景良好。

废铍铜

2017-06-06 17:50:07

废铍铜,是指暂时失去使用价值的铍铜。所有的 金属 材料都来自于 金属 矿产资源。由于矿产资源有限且不可再生,随着人类的不断开发,这些资源在不断的减少,资源短缺必然成为人类。世界大部分 金属 都能以再生 金属 的形式循环利用,工业发达国家再生 金属产业 规模大,再生 金属 循环使用比率高。由于 市场 需求强劲,中国 有色金属产业 的发展突飞猛进,中国已成为世界 有色金属 的生产和消费大国,中国的再生 金属产业 在世界再生 金属产业 的发展中有着举足轻重的地位。废铍铜回收的意义:铍铜使用过程中的新旧更替现象是必然的,由于 金属 制品的腐蚀、损坏和自然淘汰,每年都有大量的废旧 金属 产生。如果随意弃置这些废旧 金属 ,既造成了环境的污染,又浪费了有限的 金属 资源。有人曾做过这样的估计:回收一个废弃的铝质易拉罐要比制造一个新易拉罐节省20%的资金,同时还可节约90%~97%的能源。回收1t废钢铁可炼得好钢0.9t,与用矿石冶炼相比,可节约成本47%,同时还可减少空气污染、水污染和固体废弃物。可见,树立可持续发展的观念、加强垃圾的分类处理、回收并循环利用废旧 金属 有着巨大的经济效益喝社会效益。金属 回收 产业 形成了一个完整的 产业 链及再生利用生态圈。这个 产业 链从国外废料供货商开始,经过贸易商、进口商、代理商、港口、拆解厂(定点企业或五金厂)、回收公司、 金属 加工厂等环节,实现了资源的有效利用。需要指出的是,这里的 金属 回收公司是一个特殊的群体。各个 金属 回收公司在一个个大小不等的场地忙碌地从事着废 金属 的收购、分选、打包、装运等工作,他们既从事国内废料的回收,又在国内资源回收量尚为有限的情况下,大量收购经过初选及拆解后的进口废 金属 。在整个 金属 回收 产业 链中,经过 金属 回收公司的环节,各种废 金属 进行了富集,可以说, 金属 回收公司在这里起到了一个重要的"储水池"作用,调节着 金属 废料的供需、物流。 金属 回收将向分工专业化,社会化方向发展。想要了解更多XX的相关资讯,请浏览上海 有色 网( www.smm.cn )铜频道。
