冷轧钢板

2019-03-18 11:00:17

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

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。

热轧钢材是经过高温加热轧制而成的钢材,它的强度不是很高,但足以满足我们的使用,它的塑性、可焊性较好,因此我们比较常用;冷轧钢是普通热轧钢经过强力拉拔超过应变硬化阶段的钢材,它的强度很高,但韧性、可焊性差,比较硬、脆!    热轧低碳钢 Q/BQB 302 SPHCSPHDSPHE JIS G3131 SPHCSPHDSPHE 适用于制造冷成型加工的零件。  StW22StW23StW24 DIN 1614(EN10111) StW22 (DD11)STW23 (DD12)StW24 (DD13)  一般结构用钢 Q/BQB 303 SS 330SS 400SS 490SS 540 JIS G3101 SS 330SS 400SS 490SS 540 用于建筑、桥梁、船舶、车辆等一般结构件。  St 33St 37-2St 37-3St 44-2St 50-2St 52-3 DIN 17100(EN10025) St 33 (S185)St 37-2 (S235JR)St 37-3 (S235JO)St 44-2 (S275JR)St 50-2 (E295)St 52-3 (S355JO)  焊接结构用钢 Q/BQB 303 SM 400ASM400BSM 400CSM 490ASM490BSM 490CSM490YASM490YBSM520BSM 520C JIS G3106 SM 400ASM400BSM 400CSM 490ASM490BSM 490CSM490YASM490YBSM520BSM 520C 用于建筑、桥梁、船舶、车辆、石油罐、工程机械等要求焊接性能优良的结构件。  B520JJ --- --- 混凝土搅拌车筒体用热连轧钢板。  Welten590RE NSC Welten590RE 可焊高强度钢板,用于压力容器、油罐、工程机械、采矿机械、压力水管等。  B590GJAB590GJB --- ---  机械结构用钢 Q/BQB 303 C 22C35S 20CS 35C DIN 17200JIS G4501 C 22C35S 20CS 35C 用于经切削等加工并热处理后使用的机械结构件。  细晶粒结构钢 --- StE255StE355 DIN 17102 StE255StE355 适用于焊接的细晶粒结构钢。  钢管用钢带钢 Q/BQB 303 SPHT1SPHT2SPHT3 JIS G3132 SPHT1SPHT2SPHT3 用于焊接钢管。  汽车结构用钢 Q/BQB 310BZJ 311BZJ 312BZJ 313BZJ 314 SAPH 310SAPH 370SAPH 400SAPH 440 JIS G3113 SAPH 310SAPH 370SAPH 400SAPH 440 用于要求成形性加工性能的汽车构架、车轮等汽车结构件。  QStE 340TMQStE 380TMQStE 420TMQStE 460TMQStE 500TM SEW 092(EN10149-2) QStE 340TM (---)QStE 380TM (---)QStE 420TM (S420MC)QStE 460TM (S460MC)QStE 500TM (S500MC) 冷变形用热轧粒钢,用于要求良好冷成型性能并有较高或高强度要求的汽车大梁等结构件。  B330CLB380CLB420CL --- --- 有良好冷成型性能,用于汽车滚型车轮轮网及轮幅。  B440QZRB480QZR --- --- 制造汽车传动轴管用。  B 320L B 550LB 510L B 420LB 510DL --- --- 汽车大梁、横梁用。  锅炉及压力容器用钢 Q/BQB 320 HII19Mn6 DIN 17155 (EN10028-2) HII (P265GH)19Mn6 (P355GH) 除保证常温性能外,还保证较高温度下的力学性能,适用于蒸汽锅炉设备,较高工作温度的压力容器及类似结构件。  Q/BQB 320 SB410 JIS G3103 SB410  Q/BQB 321 B440HPB490HP JIS G3116 SG295SG325 焊接气瓶用钢板。  船体结构用钢 Q/BQB 330 ABD LR,BVGL,DNV 及ABS 船规 ABD 可按各国船级社规范供货。  耐大气腐蚀钢 Q/BQB 340 WTSt37-2WTSt52-3 SEW087 (EN10155) WTSt37-2 (S235J2W)WTSt52-3 (S355J 2G 1W) 用于制造集装箱、铁道车辆、石油井架、工程机械等要求耐大气腐蚀的结构件截流和燃料。  NAW 400NAW 490 NSC NAW 400NAW 490  B460NQRB490NQR --- ---  耐硫酸腐蚀钢 S-ten2 NSC S-ten2 用于制造含介质的容器等。  耐海水腐蚀钢 Mariloy G 41AMariloy S 50A Mariloy G 41AMariloy S 50A 用于采油平台、船舶、海港建筑等结构构件。  高耐候性结构钢 BZJ342 B480GNQR --- --- 用于制造车辆、集装、建筑及其它结构件。  厚度方向性能热连轧钢板 Q/BQB 350 Z15Z25Z35 --- --- 钢板厚度方向性能有良好的抗层状撕裂性能,用于海上采油平台及其它要求厚度性能的结构件。  表面硬化钢 Q/BQB 360 C 10C15 DIN 17210 C 10C15 高纯净低碳钢,供进行表面渗碳或渗氮后进行淬火硬化制造表层高硬度、耐磨、芯部具高韧性的结构件。  S09CKS15CK JIS G4051 S09CKS15CK  高韧性管线钢 BZJ 371 X60RLX70RL API 5L X60X70 供螺旋焊生产石油输送管用高韧性管线钢热轧宽带钢  直缝焊接套管用钢 BZJ 372 J55 API 5CT J55 供制造直缝焊石油套管用  花纹钢板 BZJ 390 BCP 270BCP 340BCP 400 --- --- 扁豆型花纹钢板  自行车用热连轧宽带钢 BZJ 304 SPHT1Z,SPHT2ZSPHT3Z,SPHDZSM50BZ,SM53BZ --- --- 用于制造自行车上、下、后接头,前叉肩、前花盘、链条滚车把横管,中轴等零件  管线用热连轧卷 GB 14164 S205,S240S315S290,S360,S385S415,S450,S480 API 5L Grade A,BX42,X46,X52X56,X60,X65X70 石油、天然气输送管用  1 、热连轧钢板产品简介:     热连轧钢板、带产品,是以板坯(主要为连铸坯)为原料,经加热后由粗轧机组及精轧机组制成带钢。从精轧最后一架轧机出来的热钢带通过层流冷却至设定温度,由卷取机卷成钢带卷,冷却后的钢带卷,根据用户的不同需求,经过不同的精整作业线(平整、矫直、横切或纵切、检验、称重、包装及标志等)加工而成为钢板、平整卷及纵切钢带产品。由于热连轧钢板产品具有强度高,韧性好,易于加工成型及良好的可焊接性等优良性能,因而北广泛应用于船舶、汽车、桥梁、建筑、机械、压力容器等制造行业。随着热轧尺寸精度、板形、表面质量等控制新技术的日益成熟以及新产品的不断问世,热连轧钢板、带产品得到了越来越广泛的应用并在市场上具有越来越强的竞争力。一般说明热连轧钢板产品,钢种规格品种繁多,用途广泛,从一般的工程结构至汽车、桥梁、船舶、锅炉压力容器等制造,都得到大量使用。各种不同用途,对钢板的材质性能、表面质量及尺寸、外形精度等要求也各不相同,因此,必须对热轧钢板产品的品种、材质、特性及其用途有所了解,才能做到经济、合理利用。 2 、力学性能考虑要点 力学性能名词术语( 1 )力学性能: 钢板的力学性能式指钢板在受力作用下所显示与弹性或非弹性反应相关或涉及应力——应变关系的性能。抗拉强度、屈服点、伸长率及冲击吸收功是表示热轧钢板力学性能的主要指标。其大小表示钢材抵抗各种作用的能力的大小,是评定钢板材料质量的主要判据,也是钢板制件设计时选材和进行强度计算的主要依据。 ( 2 )力学性能实验: 测定热轧钢板力学性能的实验主要有拉伸试验及冲击试验等。 ( 3 )屈服强度: 试样在拉伸过程中,负荷不增加或开始有所降低而试样仍能继续伸长(变形)时的应力。钢材的屈服强度愈低,产生永久变形所需的力愈小,即愈容易成形加工。( 4 )抗拉强度: 试样拉伸时,在拉断前所承受的最大应力。当材料所受的外应力大于其抗拉强度时,将会发生破裂,因此,钢板材料的抗拉强度愈大,则表示它愈能承受大的外应力而不断裂。 ( 5 )伸长率: 试样在拉断后,其标距部分所增加的长度与原标距长度的百分比。伸长率的比数愈大,则表示材料在受力破坏前可以经受永久变形的性能(塑性)愈好;反之则塑性愈差。 ( 6 )冲击功 (冲击吸收功):冲击试验时,规定形状和尺寸的试样在冲击力一次作用下折断时所吸收的功,冲击功的大小,表示金属材料对冲击负荷的抵抗能力。冲击功愈高,则材料抗突然脆断的能力愈强。 3 、热连轧钢板产品的选用 1 )力学性能与可成形性及使用性能的关系    要使钢板获得所需的形状,必须使其永久变形,所采取的工艺可以是局部或整体弯曲、深冲、张拉或这些成型方法的组合。( 1 )薄钢板的屈服强度表示出成形后的可成形性和强度,对普通碳素钢板的成形,屈服点值过高,常常有可能发生过大的回弹、成形时容易破断,磨具磨损快以及由于塑性不良而出现缺陷。然而材料的屈服点小于 140Mpa 时,又可能经受不住成形过程中施加的应力,对用于较复杂或复杂成形加工或冲压加工的钢板,通常要求具有比较低的屈服强度值,而且屈服比值愈小,由钢板的成形性能愈好。( 2 )中厚板的冷态可成形性与材料的屈服强度和伸长率有直接关系。屈服强度值愈低,产生永久变形所需的应力愈小;伸长率值愈高,高的延展性可以允许承受大的变形量而不致断裂。 ( 3 )对用于建筑结构、桥梁及机械结构件的钢板,为防止构件断裂,要求钢板材料具有特点的抗拉强度,而为防止构件变形,又要求钢板材料具有一定的屈服强度,因此对这类用途的钢材都要求规定抗拉强度、屈服强度的最小值或范围值。 ( 4 )对用于承受冲击负荷变形,例如船舶、桥梁、石油、天然气管线用钢板,为防止其使用中发生脆性断裂,又要求其具有一定足够高的冲击韧性 - 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。

怎样添加黄铜的硬度?黄铜怎样自己硬度?黄铜是咱们日子中常见的一种金属合金,在咱们印象中,黄铜的硬度一般都是不高的,相关于其他金属合金来说比较软,那么,有没有什么方法能够添加黄铜的硬度呢?下面小编就为我们带来添加黄铜硬度的!黄铜  怎样添加黄铜的硬度?在铝黄铜中添加微量钴研讨微量钴、冶炼铸造技术及制作技术参数对轧制法加工的带材的机械功能的影响.探究选用铝黄铜代替现在广泛运用的弹性铜合金材料.锡磷青铜的可行性.  研讨结果显现:钴能有用削减铸态合金的晶粒尺度、改动晶粒的形状,进步合金的抗拉强度、硬度,并确保合金具有较好的延展性.铝黄铜中添加0.4%钴.选用合理的制作技术加工出的黄铜带具有比锡磷青铜更优异的功能,0.25mm厚的带材,其抗拉强度可达840.4MPa,伸长率为2.8%,维氏硬度值为228,比特硬状况的QSn6.5-0.1带材的抗拉强度最大值(805MPa)进步了4.4%,满意弹性元件的运用要求;一起,因为该黄铜中含有22.7%的锌,可有用下降成本,具有实践使用价值.  黄铜管是由铜和锌所组成的合金。假如仅仅由铜、锌组成的黄铜就叫作普通黄铜。假如是由二种以上的元素组成的多种合金就称为特殊黄铜。如由铅、锡、锰、镍、铅、铁、硅组成的铜合金。黄铜有较强的耐磨功能。特殊黄铜又名特种黄铜,它强度高、硬度大、耐化学腐蚀性强。还有切削制作的机械功能也较杰出。由黄铜所拉成的无缝铜管,质软、耐磨功能强。黄铜无缝管可用于热交换器和冷凝器、低温管路、海底运送管。制作板料、条材、棒材、管材,铸造零件等。含铜在62%~68%,塑性强,制作耐压设备等。  怎样添加黄铜的硬度?依据黄铜中所含合金元素品种的不同,黄铜分为普通黄铜和特殊黄铜两种。压力制作用的黄铜称为变形黄铜。  1.普通黄铜管  (1)普通黄铜的室温安排普通黄铜是铜锌二元合金,其含锌量改变规模较大,因而其室温安排也有很大不同。依据Cu-Zn二元状况图(图6),黄铜的室温安排有三种:含锌量在35%以下的黄铜,室温下的显微安排由单相的α固溶体组成,称为α黄铜;含锌量在36%~46%规模内的黄铜,室温下的显微安排由(α+β)两相组成,称为(α+β)黄铜(两相黄铜);含锌量超越46%~50%的黄铜,室温下的显微安排仅由β相组成,称为β黄铜。  (2)压力制作功能α单相黄铜管(从H96至H65)具有杰出的塑性,能接受冷热制作,但α单相黄铜在铸造等热制作时易呈现中温脆性,其详细温度规模随含Zn量不同而有所改变,一般在200~700℃之间。因而,热制作时温度应高于700℃。单相α黄铜中温脆性区发作的原因主要是在Cu-Zn合金系α相区内存在着Cu3Zn和Cu9Zn两个有序化合物,在中低温加热时发作有序改变,使合金变脆;别的,合金中存在微量的铅、铋有害杂质与铜构成低熔点共晶薄膜散布在晶界上,热制作时发作晶间决裂。实践标明,参加微量的铈能够有用地消除中温脆性。  含锌量大于46%~50%的β黄铜因功能硬脆,不能进行压力制作。  (3)机械功能黄铜中因为含锌量不同,机械功能也不一样,图7是黄铜的机械功能随含锌量不同而改变的曲线。关于α黄铜,跟着含锌量的增多,σb和δ均不断增高。关于(α+β)黄铜,当含锌量添加到约为45%之前,室温强度不断进步。若再进一步添加含锌量,则因为合金安排中呈现了脆性更大的r相(以Cu5Zn8化合物为基的固溶体),强度急剧下降。(α+β)黄铜的室温塑性则一直随含锌量的添加而下降。所以含锌量超越45%的铜锌合金无实用价值。  2.特殊黄铜  为了进步黄铜的耐蚀性、强度、硬度和切削性等,在铜-锌合金中参加少数(一般为1%~2%,少数达3%~4%,极个别的达5%~6%)锡、铝、锰、铁、硅、镍、铅等元素,构成三元、四元、乃至五元合金,即为杂乱黄铜,亦称特殊黄铜。  铅黄铜:铅实践不溶于黄铜内,呈游离质点状况散布在晶界上。铅黄铜按其安排有α和(α+β)两种。α铅黄铜因为铅的有害效果较大,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,可进行铸造。  锡黄铜:黄铜中参加锡,可明显进步合金的耐热性,特别是进步抗海水腐蚀的才能,故锡黄铜有“水兵黄铜”之称。锡能溶入铜基固溶体中,起固溶强化效果。可是跟着含锡量的添加,合金中会呈现脆性的r相(CuZnSn化合物),不利于合金的塑性变形,故锡黄铜的含锡量一般在0.5%~1.5%规模内。  常用的锡黄铜有HSn70-1,HSn62-1,HSn60-1等。前者是α合金,具有较高的塑性,可进行冷、热压力制作。后两种牌号的合金具有(α+β)两相安排,并常呈现少数的r相,室温塑性不高,只能在热态下变形。  锰黄铜:锰在固态黄铜中有较大的溶解度。黄铜中参加1%~4%的锰,可明显进步合金的强度和耐蚀性,而不下降其塑性。  锰黄铜具有(α+β)安排,常用的有HMn58-2,冷、热态下的压力制作功能相当好。  铁黄铜:铁黄铜中,铁以富铁相的微粒分出,作为晶核而细化晶粒,并能阻挠再结晶晶粒长大,然后进步合金的机械功能和技术功能。铁黄铜中的铁含量通常在1.5%以下,其安排为(α+β),具有高的强度和耐性,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:镍与铜能构成接连固溶体,明显扩展α相区。黄铜中参加镍可明显进步黄铜在大气和海水中的耐蚀性。镍还能进步黄铜的再结晶温度,促进构成更细的晶粒。   以上便是今日小编为我们带来的关于“怎样添加黄铜的硬度”的介绍,期望能对各位有所协助。拓宽阅览:黄铜管体积的计算方法黄 铜价 格一斤?h85黄铜棒化学成分及其使用【组图】h65黄铜板特色及其应用范围【组图】铜及铜合金的标准-板材标准

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 、

镍的硬度

2017-06-06 17:49:54

金属镍的硬度标准为HRC28电镀镍层的硬度仅为HV160~180。知道的镍的硬度,让我们来更详细的了解下化学镀镍如何调整镍的硬度?锌层易溶解于酸性化学镀镍溶液中;由于基体与镍层之间夹杂锌层,在腐蚀介质中形成电偶腐蚀(al-zn-ni),将导致镀层鼓泡或脱落,降低耐蚀性;经浸锌后化学镀镍,不宜进行400oc热处理,会造成浸锌层空松。同时铝和镍膨胀系数相差悬殊,在高温时会引起足够的应力,使镀层与铝之间产生破裂。而以活化代替浸锌,为化学镀镍提供了一个较好的底层,镀层与在材有结合力能达到同浸锌一样好的结果,是一种很有用途的铝合金前处理新工艺。活化处理液为:niso4。6h2024~30g/l,hedp 40~50g/l,稳定剂n25~30ml/l,ph(naoh调整)>12,室温,1~4min。控制活化时间至关重要,对某一具体配方,可通过实验杰确定最佳浸清时间,即当表面完全呈均匀灰色时,进行化学镀镍可得到最佳镀层质量。如何保证电子微组铝件化学镀镍的质量微组铝件(放大器铝腔体、微波开关、振荡器和天线蚀电架等)化学镀镍取代铝镀银工艺必须保证外观装饰性、优异附着力、耐腐蚀性和理想的物理、化学特性(电磁屏蔽、焊接性、高硬度、耐磨、高低温等)。关键在于优化工艺配方和镀层组合。典型工艺流程:有机溶剂支油(lyc2被镀铝件)→碱性除油(或碱腐蚀) →硝酸浸蚀→二次浸锌→碱性化学镀镍→酸性化学镀镍→热处理(1)改良特殊预处理工艺选择了含镍盐和辅助络合剂的改良锌酸盐酸方,碱浓度适中,特别是含有镍盐,并将酒石酸钾钠含量升高,又增加添加剂,使镍离子呈较稳定络离子开式存在,从而使镍离子与锌离子一起缓慢而均匀地置换沉积在铝表面,得到的锌镍合金层比从传统浸锌液中获得的浸锌层更薄更均匀。且控制zn-ni层重量在1~2mg/dm2范围,能充分保证铝上镀层附着力和抗蚀性良好;特别是含镍的锌层为随后的化学镀镍沉积初期提供了充足的催化核心,得到均匀细小晶核,这是提高随后镀镍层附着力的一上重要因素。改良锌酸盐配方:naoh 240g/l,znso4 120g/l,niso4 60g/l,knac4h4o6 120g/l,添加剂10~30g/l,室温,2~3min。(2)改善预镀底层由于锌层不耐性液腐蚀,必须预镀碱性化学镀镍作底层。但碱性镀镍液存在沉积速度较慢(5~10m),含p量较低(4%~6%),抗蚀性较差等缺点。要求改变还剂和络合剂浓度,选择最佳期ph值范围,保证镀液稳定,镀速适中,并能在浸锌层表面得到一层结晶细小、均匀与基体结合良好的预镀薄镍层。改进碱性镀镍配方:niso4。6h2o 25g/l,nah2po。h2o 25g/l,na3c6h5o7 45g/l nh4cl 30g/l,35~45oc,ph=8~9(3)提高镍的硬度的防护性与装饰性优选酸性化学镀镍配方,含有少量学亮剂,镍离子与次亚磷酸根子的摩尔浓度比值控制在0.4左右,保证镀速适中(16~20m/h),溶液稳定(6周期以上,即使煮沸镀液也不会分解)。此外加入复合络合剂,防止生成亚磷酸镍沉淀。从本久液中可镀出呈学亮黄白色的镍层(含磷量8%~10%),耐蚀性好(镍层厚度25μm经中性盐雾试验48h,耐蚀等级9.5)。

铝棒硬度过低的方法

2019-01-14 11:15:13

1、铝棒时效炉温的设定与控制:通常,时效炉温与时效炉表显温度存在一定的误差,设定表温时要根据炉子的实际温度来进行设定,并密切关注时效炉温的波动情况。    2、铝棒时效保温:要严格按照工艺要求来进行时效,保温时间要适当,防止欠时效或过时效而导致硬度不够。坯料装框、装炉    3、铝棒挤压装框不能过密,料与料之间要有间隔,特别是不通风的小料、厚料间隔更加要大些,管料与小料、板料合装一框时,管料放下面这样有利于时效循环送风。    4铝棒装炉前要将6xxx的其它特殊合金与普通6063合金分开装炉时效,由于生产的原因确实要同炉时效时,要取用特殊合金的工艺来进行时效。    挤压生产出来的6061铝棒,未经时效前硬度偏低,不能作为成品使用,因此,一般来说,都必须经过时效来提高强度。通常,时效可分为自然时效和人工时效两种,目前6xxx铝型材生产基本上还是以后者为主。

纯铜硬度

2017-06-06 17:50:05

纯铜硬度较差,但韧性好,1克的铜可以拉成3000米长的细丝,或压成10多平方米几乎透明的铜箔,所以应用非常广泛。    机械工程:       几乎在所有的机器中都可以找到铜制品部件。除了电机、电路、油压系统、气压系统和控制系统中大量用铜以外,种类繁多用黄铜和青铜制造的传动件和固定件,如齿轮、蜗轮、蜗杆、联结件、紧固件、扭拧件、螺钉、螺母等,比比皆是。几乎在所有作机械相对运动的部件之间,都要使用减磨铜合金制作的轴承或轴套,特别是万吨级的大型挤压机、锻压机的缸套、滑板几乎都用青铜制成,铸件重量可达数吨。许多弹性元件,几乎都选用硅青铜和锡青铜作为材料。焊接工具、压铸模具等更离不开铜合金,如此等等。    冶金设备:       冶金工业是消耗电能的大户,素有"电老虎"之称。在冶金厂的建设中通常必须要有一个依靠铜来进行工作的庞大的输、配电系统和电力运转设备。此外,在火法冶金中,连续铸造技术已占据主导地位,其中的关键部件一结晶器,大都采用铬铜、银铜等高强度和高导热性的铜合金。电冶金中的真空电弧炉和电渣炉水冷坩埚使用铜管材制造,各种感应加热的感应线圈都是用铜管或异型铜管绕制而成,内中通水冷却。    钟表       目前生产的钟表,计时器和有钟表机构的装置,其中大部分的工作部件都用"钟表黄铜"制造。合金中含1.5-2%的铅,有良好加工性能,适合于大规模生产。例如,齿轮由长的挤压黄铜棒切出,平轮由相应厚度的带材冲出,用黄铜或其它铜合金制作搂刻的钟表面以及螺丝和接头等等。大量便宜的手表用炮铜(锡锌青铜)制造,或镀以镍银(白铜)。一些著名的大钟都用钢和铜合金制作。英国"大笨钟"的时针用的是实心炮铜杆,分针用的是14英尺长的铜管。    管道系统       由于铜水管具有美观耐用、安装方便、安全防火、卫生保健等诸多优点,使它与镀锌钢管和塑料管相比存在明显优越的 价格 性能比。在住宅和公用建筑中,用于供水、供热、供气以及防火喷淋系统,日益受到人们的青睐,成为当前的首选材料。在发达国家中,铜制供水系统己占很大比重。美国纽约号称世界第六高楼的曼哈顿大厦,其中仅供水系统一项,就用去铜管 6万英尺 (l公里)。在欧洲,饮水用钢管消耗量很大。英国的饮水用钢管消耗量平均每人每年1.6公斤,日本为0.2公斤。由于镀锌钢管容易锈蚀,许多国家己明令禁用。香港早于1996年 1月起禁止使用,上海也于 1998年5月起实行。我国在房屋建设中推广使用铜管道系统,势在必行。   纯铜硬度不必不锈钢差,但易断裂。 

6061铝硬度

2017-06-06 17:50:10

6061铝硬度接近或超过优质钢,而且塑性好工业上广泛使用,使用量仅次于钢。    修伤是铝合金模锻工艺中的重要一环。由于铝合金在高温下较软,粘性大,流动性差,容易粘模并产生各种表面缺陷(折叠、毛刺、裂纹等),在进行下一道工序前,必须打磨、修伤,将表面缺陷清除干净,否则在后续工序中缺陷将进一步扩大,甚至引起锻件报废。修伤用的工具有风动砂轮机、风动小铣刀、电动小铣刀及扁铲等。修伤前先经腐蚀查清缺陷部位,修伤处要圆滑过渡,其宽度应为深度的5~10倍。  高强度铝合金指其抗拉强度大于480兆帕的铝合金,主要是压力加工铝合金中防锈铝合金类、硬铝合金类、超硬铝合金类、锻铝合金类、铝锂合金类。    硅对硬质合金有腐蚀作用。虽然一般将超过12%Si的铝合金称为高硅铝合金,推荐使用金刚石刀具,但这不是绝对的,硅含量逐渐增多对刀具的破坏力也逐渐加大。因此有些厂商在硅含量超过8%时就推荐使用金刚石刀具。 硅含量在8%-12%之间的铝合金是一个过渡区间,既可以使用普通硬质合金,也可以使用金刚石刀具。但使用硬质合金应使用经PVD(物理镀层)方法、不含铝元素的、膜层厚度较小的刀具。因为PVD方法和小的膜层厚度使刀具保持较锋利的切削刃成为可能(否则为避免膜层在刃口处异常长大需要对刃口进行足够的钝化,切铝合金就会不够锋利),而膜层材料含铝可能使刀片膜层与工件材料发生亲合作用而破坏膜层与刀具基体的结合。因为目前的超硬镀层多为铝、氮、钛三者的化合物,可能会因硬质合金基体随膜层剥落时少量剥落造成崩刃。    了解更多有关6061铝硬度的信息,请关注上海 有色 网。

黄铜的硬度

2019-05-29 18:37:28

黄铜的硬度多少?黄铜的硬度单位是什么?黄铜铸造增加硬度的办法是什么?  在介绍黄铜硬度之前,先来介绍几个相关概念。  首要,硬度便是指材料部分反抗硬物压入其表面的才能称为硬度。  其次,硬度也有不同分类,相对应硬度的符号也不相同,“HRB”意为洛氏硬度符号。  洛氏硬度介绍:  洛氏硬度实验选用三种实验力,三种压头,它们共有9种组合,对应于洛氏硬度的9个标尺。这9个标尺的运用涵盖了简直一切常用的金属材料。最常用标尺是HRC、HRB和HRF,其间HRC标尺用于测验淬火钢、回火钢、调质钢和部分不锈钢。这是金属制作职业运用最多的硬度实验办法。HRB标尺用于测验各种退火钢、正火钢、软钢、部分不锈钢及较硬的铜合金。HRF标尺用于测验纯铜、较软的铜合金和硬铝合金。HRA标尺虽然也可用于大多数黑色金属,可是实践运用上一般只限于测验硬质合金和薄硬钢带材料。黄铜带  黄铜可分为普通黄铜与特殊黄铜,它们又有着许多不同的牌号,功能特色也有所不同,其间就包含它们的硬度,下面就让咱们一同经过黄铜硬度表来了解它们各自的硬度吧。  黄铜的硬度表:合金牌号硬度普通黄铜H90HRB53/130H85HRB54/126H80HRB53/145H68HRB--/150H63HRB56/140H62HRB56/164H60HRB--/163铅黄铜Hpb89-2HRF55HRB58Hpb66-0.5HRF64HRF75HRF100HRB85Hpb63-3HRB40HRB86Hpb62-3HRB68HRF28Hpb59-14480铝黄铜HAl77-2HRB65/170HAl61-4-3-1HRB230HAl60-1-1HRB80/170HAl59-3-2HRB75/155锰黄铜HMn62-3-3-0.7HRB170-200HMn57-3-1HRB115/175HMn58-2HRB85/120锡黄铜HSn90-1HRB13/82HSn70-1HRB16/95HSn62-1HRB50/95HSn60-1HRB50/80铁黄铜HFe59-1-1HRB80/160镍黄铜HNi65-5HRB90/110硅黄铜HSi80-3HRB90/110HV60/180  黄铜铸造增加硬度的办法:  在铝黄铜(72.5Cu-22.7Zn-3.4Al)中增加微量钴(0.2%,0.4%,0.6%),研讨微量钴、冶炼铸造技术及制作技术参数对轧制法加工的带材的机械功能的影响。探究选用铝黄铜代替现在广泛运用的弹性铜合金材料。锡磷青铜的可行性研讨结果显现:钴能有用削减铸态合金的晶粒尺度、改动晶粒的形状,进步合金的抗拉强度、硬度,并确保合金具有较好的延展性.铝黄铜中增加0.4%钴。选用合理的制作技术加工出的黄铜带具有比锡磷青铜更优异的功能,0.25mm厚的带材,其抗拉强度可达840.4MPa,伸长率为2.8%;维氏硬度值为228,比特硬状况的QSn6.5-0.1带材的抗拉强度最大值(805MPa)进步了4.4%,满意弹性元件的运用要求;一起因为该黄铜中含有22.7%的锌,可有用降低成本,具有实践运用价值。  以上为黄铜的硬度全部内容,期望对您能有所协助。
