冷轧钢板

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

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

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。

镀锌钢带

2017-06-06 17:50:05

镀锌钢带——钢带(steel-belt)   以碳钢制成的输送带作为带式输送机的牵引和运载构件。   钢带的特性分类   钢带是 产量 大、用途广、品种多的钢材。按加工方法分为热轧钢带和冷轧钢带;按厚度分为薄钢带(厚度不大于4mm)和厚钢带(厚度大于4mm);按宽度分为宽钢带(宽度大于600mm)和窄钢带(宽度不大于600mm);窄钢带又分为直接轧制窄钢带和由宽钢带纵剪窄钢带;按表面状态分为原轧制表面和镀(涂)层表面钢带;按用途分为通用和专用(如船体、桥梁、油桶、焊管、包装、自生车等)钢带。   钢带是各类轧钢企业为了适应不同工业部门工业化生产各类 金属 或机械产品的需要而生产的一种窄而长的钢板。钢带又称带钢,是宽度在1300mm以内,长度根据每卷的大小略有不同。带钢一般成卷供应,具有尺寸精度高、表面质量好、便于加工、节省材料等优点。同钢板相同,钢带按所用材质分为普通带钢和优质带钢两类;按加工方法分热轧钢带、冷轧带钢带两种。

冲击功值。 2 )钢板品种类别的选用 .    热连轧钢板产品包括带(卷)及由其剪切而成的钢板。而钢带(卷)又可分为直发卷及精整卷(分卷,平整分卷及纵切带卷)。    由于直发卷未经重卷,未切除钢带头尾尺寸变化部分并且未经矫直和平整,因此直发卷带有舌头和鱼尾,并且容易发生头尾厚度、宽度不均,边部浪形,折边、塔形以及开卷后出现折皱(腰折)等缺陷,因此对钢板的表面质量,板形要求比较高的用途而言,不宜选用热轧直发卷,而应选用经过精整线重卷、平整的平整卷。 5、“热轧带钢 ” 1.产品:普通碳素结构钢钢带 标准:( GB/T3524-1992 、 GB/T8164-1993 、 QJ/HG02.22-1995 规格:厚度: 2.0 -5.0mm 宽度: 100 -230mm 钢种: HG5 、 Q215 、 Q235 2.产品:优质碳素结构钢钢带 标准:( GB8749-1998 、 GB/T8164-1993 size="3"> ) 规格:厚度: 2.5 -4.5mm 宽度: 钢种: 10# 、 20# 、 45# 、 50# 、 40Mn 、 45Mn 、 65Mn 3.产品:自行车链条用钢带 标准: QJ/HG02.15-1991 规格:厚度: 2.75 -4.5mm 宽度: 125 -205mm 钢种: ZL20MnSi 用途:焊接管用、工业链条用、自行车变速链条用、建筑机械、工具用、弹簧用(卷帘门弹簧、卡簧等) “ 冷轧带钢 ” 1.产品:碳素结构钢冷轧钢带 标准:( GB716-1991 、 QJ/HG02.22-1995 ) 规格:厚度: 0.5 -2.0mm 宽度:≤ 205mm 钢种: HG5 、 Q215 、 Q235 2.产品:优质碳素结构钢冷轧钢带 标准: GB3522-1983 规格:厚度: 0.5 -2.0mm 宽度:≤ 205mm 钢种: 10# 、 20# 、 40Mn 、 45# 、 50# 3.产品:自行车链条用冷轧钢带 标准:( QJ/HG02.15-1991 、 GB3522-1983 ) 规格:厚度: 0.5 -2.0mm 宽度: 125 -205mm 钢种: ZL20MnSi 用途:工业链条用、自行车变速链条用、刀具用、家具用 “ 小型材 ” 1.产品:圆钢(小轧股份公司生产) 标准:( GB699-1988 、 GB700-1988 、 GB3077-1988 、 GB702-1986 、 QJ/HG02.17-1991 ) 规格: 10 -42mm ( 10 、 12 、 14 、 16 、 18 、 20 、 22 、 25 、 28 、 30 、 32 、 34 、 35 、 36 、 38 、 40 、 42mm ) 钢种: Q215 、 Q235 、 45# 、 50# 、 HG3 、 20CrMnTi 、 20Cr 、 20CrMo 、 35CrMo 、 42CrMo 、 60Si2Mn 、 40Cr 用途:机械零件、轴、五金工具、齿轮用钢、标准件用钢等;螺铆、螺栓、轴、销、自行车、摩托车等配 件 2.产品:螺纹钢筋 标准 :(GB1499-1991 、 BS4449:1988 ) 规格: 10 、 12 、 14 、 16 、 18 、 20 、 22 、 25 、 28 、 32 、 36 、 40mm 钢种: 20MnSi 、 20MnV 、 25MnSi 、 BS20MnSi 。 用途:建筑用材、包括可供高层建筑用材。(钢筋混凝土结构用)

不锈钢带

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

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。

热轧钢管生产工艺流程

2019-03-15 09:13:19

热轧是在再结晶温度以上进行的轧制。可以破坏钢锭的铸造组织,细化钢材的晶粒,并消除显微组织的缺陷,从而使钢材组织密实,力学性能得到改善。这种改善主要体现在沿轧制方向上,从而使钢材在一定程度上不再是各向同性体;浇注时形成的气泡、裂纹和疏松,也可在高温和压力作用下被焊合。热轧钢管生产工艺流程 热轧无缝钢管的生产工艺流程包括坯料轧前准备、管坯加热、穿孔、轧制、定减径和钢 管冷却、精整等几个基本工序。 当今热轧无缝钢管生产的一般主要变形工序有三个:穿孔、轧管和定减径;其各自的工 艺目的和要求为: 热轧钢管生产穿孔 将实心的管坯变为空心的毛管;我们可以理解为定型,既将轧件断面定为圆环状;其设 备被称为穿孔机。对穿孔工艺的要求是:首先要保证穿出的毛管壁厚均匀,椭圆度小,几何 尺寸精度高;其次是毛管的内外表面要较光滑,不得有结疤、折叠、裂纹等缺陷;第三是要 有相应的穿孔速度和轧制周期, 以适应整个机组的生产节奏, 使毛管的终轧温度能满足轧管 机的要求。 2.1.2 热轧钢管生产轧管 将厚壁的毛管变为薄壁(接近成品壁厚)的荒管;我们可以视其为定壁,即根据后续的 工序减径量和经验公式确定本工序荒管的壁厚值; 该设备被称为轧管机。 对轧管工艺的要求 是: 第一是将厚壁毛管变成薄壁荒管 (减壁延伸) 时首先要保证荒管具有较高的壁厚均匀度; 其次荒管具有良好的内外表面质量。 2.1.3 热轧钢管生产定减径(包括张减) 大圆变小圆,简称定径;相应的设备为定(减)径机。对定减径工艺的要求是:首先在 一定的总减径率和较小的单机架减径率条件下来达到定径目的, 第二可实现使用一种规格管 坯生产多种规格成品管的任务,第三还可进一步改善钢管的外表面质量。 20 世纪 80 年代末,曾出现过试图取消轧管工序,仅使用穿孔加定减的方法生产无缝钢管, 简称 CPS,即斜轧穿孔和张减的英文缩写),并在南非的 Tosa 厂进行了工业试验,用来生产外径: 33.4~179.8mm,壁厚 3.4~25mm 的钢管,其中定径最小外径为 101.6mm;张减最 大外径我 101.6mm。经过实践检验,该工艺在产生壁厚大于 10mm 的钢管时质量尚可,但 在生产壁厚小于 8mm 的钢管时通过定径、张减不能完全消除穿孔毛管的螺旋线,影响了钢 管的外观质量。在随后的改造中不得不在穿孔机于定减径机之间增设了一台 MINI-MPM(4 机架)来确保产品质量。 2.2 各热轧机组生产工艺过程特点 我们通常将毛管的壁厚加工称之为轧管。轧管是钢管成型过程中最重要的一个工序环 节。 这个环节的主要任务是按照成品钢管的要求将厚壁的毛管减薄至与成品钢管相适应的程 度,即它必须考虑到后继定、减径工序时壁厚的变化,这个环节还要提高毛管的内外表面质 量和壁厚的均匀度。 通过轧管减壁延伸工序后的管子一般称为荒管。 轧管减壁方法的基本特 点是在毛管内按上刚性芯棒,由外部工具(轧辊或模孔)对毛管壁厚进行压缩减壁。依据变 形原理和设备特点的不同,它有许多种生产方法,如表 1 所示。一般习惯根据轧管机的形式 来 命 名 热 轧 机 组 。 轧 管 机 分 单 机 架和 多 机 架 ,单 机 架 有 自动 轧 管 机 、阿 塞 尔 轧 机 、

铝锭用途

2017-06-06 17:49:58

铝锭用途相关知识很多,让我们对它进行下介绍。铝锭用途:  近五十年来,铝已成为世界上最为广泛应用的金属之一。特别是近年来,铝作为节能、降耗的环保材料,无论应用范围还是用量都在进一步扩大。尤其是在建筑业、交通运输业和包装业,这三大行业的铝消费一般占当年铝总消费量的60%左右。  在建筑业上,由于铝在空气中的稳定性和阳极处理后的极佳外观,使铝在建筑业上被越来越多地广泛应用,特别是在铝合金门窗、铝塑管、装饰板、铝板幕墙等方面的应用。  在交通运输业上,为减轻交通工具自身的重量,减少废气排放对环境的污染,摩托车、各类汽车、火车、地铁、飞机、船只等交通运输工具开始大量采用铝及铝合金作为构件和装饰件。随着铝合金加工材的硬度和强度不断提高,航空航天领域使用的比例开始逐年增加。  在包装业上,各类软包装用铝箔、全铝易拉罐、各类瓶盖及易拉盖、药用包装等用铝范围也在扩大。  在其它消费领域,电子电气、家用电器(冰箱、空调)、日用五金等方面的使用量和使用前景越来越广阔。  铝锭分类铝锭按成分不同分重熔用铝锭、高纯铝锭和铝合金锭三种:按形状和尺寸又可分为条锭、圆锭、板锭、T形锭等几种,下面是几种常见的铝锭;   重熔用铝锭--15kg,20kg(≤99.80%Al):   T形铝锭--500kg,1000kg(≤99.80%Al):   高纯铝锭--l0kg,15kg(99.90%~99.999%Al);   铝合金锭--10kg,15kg(Al--Si,Al--Cu,Al--Mg);   板锭--500~1000kg(制板用);   圆 锭--30~60kg(拉丝用)。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。通过了解铝锭用途的知识,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。

锌锭用途

2017-06-06 17:49:55

锌锭用途主要有以下几个方面;(一)制造铜合金材(如黄铜);用于汽车制造和机械行业。锌具有适用的机械性能。锌本身的强度和硬度不高,但加入铝、铜等合金元素后,其强度和硬度均大为提高,尤其是锌铜钛合金的出现,其综合机械性能已接近或达到铝合金、黄铜、灰铸铁的水平,其抗蠕变性能也大幅度被提高。因此,锌铜钛合金目前已被广泛应用于小五金生产中。 (二) 用于铸造锌合金;主要为压铸件,用于汽车、轻工等行业。许多锌合金的加工性能都比较优良,道次加工率可达60%-80%。中压性能优越,可进行深拉延,并具有自润滑性,延长了模具寿命,可用钎焊或电阻焊或电弧焊(需在氦气中)进行焊接,表面可进行电镀、涂漆处理,切削加工性能良好。在一定条件下具有优越的超塑性能。三)镀锌;锌具有优良的抗大气腐蚀性能,所以被主要用于钢材和钢结构件的表面镀层(如镀锌板),广泛用于汽车、建筑、船舶、轻工等行业。近年来西方国家开始尝试直接用锌合金板做屋顶覆盖材料,其使用年限可长达120-140年,而且可回收再用,而用镀锌铁板作屋顶材料的使用寿命一般为5-10年.以上是笔者为您提供的有关锌锭用途的咨询,

现如今黄铜在人们的日常生活中和工业上产中应用的已经越来越广泛了,但是很多人对于黄铜的用途还只是停留在黄铜工艺品、铜器、化工原料等简单的理解上。到底黄铜用途是什么?了解黄铜用途,才能更好的利用黄铜。    黄铜是由铜和锌所组成的合金。如果只是由铜、锌组成的黄铜就叫作普通黄铜。黄铜常被用于制造阀门、水管、空调内外机连接管和散热器等。    黄铜用途概述: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。   更多特殊黄铜用途:    铅黄铜用途:铅实际不溶于黄铜内,呈游离质点状态分布在晶界上。铅黄铜按其组织有α和(α+β)两种。α铅黄铜由于铅的有害作用较大,高温塑性很低,故只能进行冷变形或热挤压。(α+β)铅黄铜在高温下具有较好的塑性,可进行锻造。    锡黄铜用途:黄铜中加入锡,可明显提高合金的耐热性,特别是提高抗海水腐蚀的能力,故锡黄铜有“海军黄铜”之称。    锰黄铜用途:锰在固态黄铜中有较大的溶解度。黄铜中加入1%~4%的锰,可显著提高合金的强度和耐蚀性,而不降低其塑性。    铁黄铜用途:铁黄铜中,铁以富铁相的微粒析出,作为晶核而细化晶粒,并能阻止再结晶晶粒长大,从而提高合金的机械性能和工艺性能。铁黄铜中的铁含量通常在1.5%以下,其组织为(α+β),具有高的强度和韧性,高温下塑性很好,冷态下也可变形。常用的牌号为Hfe59-1-1。    镍黄铜用途:镍与铜能形成连续固溶体,显著扩大α相区。黄铜中加入镍可显著提高黄铜在大气和海水中的耐蚀性。镍还能提高黄铜的再结晶温度,促使形成更细的晶粒。    更多关于黄铜用途的资讯,请登录上海 有色 网查询。

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。

钨条用途

2017-06-06 17:50:03

钨条用途非常广泛。钨金原名钨 金属 条,简称钨金、钨条。 钨金是世界上少有的一种 有色 矿产品,年 产量 很低,用途非常广泛,主要用于铸造配料用原料。钨金来源于一种白色砂型矿体,矿线特别微小,经过采掘、研磨、水重选、提炼等多道工艺,得到品位达到95%以上的钨矿粉,再经过高温电炉提炼成型生产出的成品才是钨金。钨金的熔点:3500℃。目前钨矿主要分布在中国和俄罗斯,中国现在是世界上最大的钨金出口国。钨条的主要用途包括:钢铁工业:   钨大部分用于生产特种钢。广泛采用的高速钢含有9%——24%的钨、3.8%——4.6%的铬、1%——5%的钒、4%——7%钴、0.7%——1.5%碳。高速钢的特点是在空气中有高的强化回火温度(700——800℃)下,能自动淬火,因此,直到600—650℃它还保持高的硬度和耐磨性。合金工具钢中的钨钢含有0.8%——1.2%的钨;铬钨硅钢含有2%——2.7%的钨;铬钨钢中含有2%——9%的钨;铬钨锰钢中含有0.5%——1.6%的钨。含钨的钢用于制造各种工具:如钻头、铣刀、拉丝模、阴模和阳模,气支工具等零件。钨磁钢是含有5.2%——6.2%的钨、0.68%——0.78%碳、0.3%——0.5%铬的永磁体钢。钨钴磁钢含有11.5%——14.5%的钨、5.5%——6.5%钼、11.5%——12.5%钴的硬磁材料。它们具有高的磁化强度和矫顽磁力。   碳化钨基硬质合金:   钨的碳化物具有高的硬度、耐磨性和难熔性。这些合金含有85%——95%的碳化钨和5%——14%的钴,钴是作为粘结剂 金属 ,它使合金具有必要的强度。主要用于加工钢的某些合金中,还含有钛、钽和铌的碳化物。所有这些合金都是用粉末冶金法制造的。当加热到1000——1100℃时,它们仍具有高的硬度和耐磨性。硬质合金刀具的切削速度远远地超过了最好的工具钢刀具的切削速度。硬质合金主要用于切削工具、矿山工具和拉丝模等。   热强和耐磨合金:   作为最难熔的 金属 钨是许多热强合金的成分,如3%——15%的钨、25%——35%的铬、45%——65%的钴、0.5%——0.75%的碳组成的合金,主要用于强烈耐磨的零件,例如航空发动机的活门、压模热切刀的工作部件、涡轮机叶轮、挖掘设备、犁头的表面涂层。   在航空火箭技术中,以及要求机器零件,发动机和一些仪器的高热强度的其它部门中,钨和其它给熔 金属 (如钽、铌、钼、铼)的合金用作热强材料。   触头材料和高比重合金:   用粉末冶金方法制造的钨-铜合金(10%——40%的铜)和钨-银合金,兼有铜和银的良好的导电性、导热性和钨的耐磨性。因此,它成为制造闸刀开关、断路器、点焊电极等的工作部件非常的效的触头材料。成分为90%——95%的钨、1%——6%的镍、1%——4%的铜的高比重合金,以及用铁代铜(—5%)的合金,用于制造陀螺仪的转子、飞机、控制舵的平衡锤、放射性同位素的放射护罩和料筐等。   电真空照明材料:   钨以钨丝、钨带和各种锻造元件用于电子管生产、无线电电子学和X射线技术中。钨是白织灯丝和螺旋丝的最好材料。高的工作温度(2200——2500℃)保证高的发光效率,而小的蒸发速度保证丝的寿命长。钨丝用于制造电子振荡管的直热阴极和栅极,高压整流器的阴极和和各种电子仪器中旁热阴极加热器。用钨做X光管和气体放电管的对阴极和阴极,以及无线电设备的触头和原子氢焊枪电极。钨丝和钨棒作为高温炉(3000℃)的加热器。钨加热器在氢气气体、惰性气体或真空中工作。   钨的化合物:   钨酸钠用于生产某些类型的漆和颜料,以及纺织工业中用于布疋加重和与硫酸铵和磷酸铵混合来制造耐火布疋和防水布疋。还用于 金属 钨、钨酸及钨酸盐的制造以及染料、颜料、油墨、电镀等方面。也用作催化剂等。钨酸在纺织工业中是媒染剂与染料和在化学工业中用作制取高辛烷汽油的催化剂。二硫化钨在有机合成中,如在合成汽油的制取中用作固体的润滑剂和催化剂。处理钨矿石的时候可得到得三氧化钨,再用氢还原三氧化钨制得钨粉,广泛用于钨材及钨冶金材原料。我国是产钨大国,钨资源储量520万吨,为国外30个产钨国家总储量(130万吨)的3倍多, 产量 及出口量均居世界第一。湖南、江西、河南三省的钨资源储量居全国的前三位,其中湖南、江西两省的钨资源储量占全国的55.48%。湖南以白钨为主,江西以黑钨为主,其黑钨资源占全国黑钨资源总量的42.40%。我国的钨矿大体上分布于我国南岭山地两侧的广东东部沿海一带,尤其是以江西的南部为最多,储量约占全世界的二分之一以上。此外,江西的大余、湖南的汝城、安化、临武、资兴、荼陵等地;以及广西和云南、四川、福建等省也有钨矿资源。国外钨矿的主要产地是加拿大和美国。钨条用途还有很大拓展空间。

锇的用途

2019-03-13 11:30:39

锇的用处 锇及其合金在石油化学工业上首要作催化剂。在电子电器工业上,作电阻、继电器、火花塞电极、电触头、热电偶及印刷电路等。在玻璃工业上,锇不会使熔化的玻璃污染,可作为制作光学玻璃时的容器内衬。锇铱合金可以作挂钟和仪器中的轴承,制作笔尖和唱针。 锇的性质 锇是铂族金属之一,呈灰兰色。熔点高,约为3050℃。密度大,为22.5克/厘米3。锇即便在高温下也不易加工,一般只用作合金元素。锇的抗氧化性很差,在空气中,室温下锇表面就生成兰色二氧化锇薄膜。硝酸与锇效果也会生成。此两种氧化物都是挥发性的有毒化合物,能影响粘损害皮肤,自然界中,锇与铂族金属常共生在一起。  .
