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。

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

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。

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。

登电集团铝加工有限公司¢360/960×1450mm冷轧机试车成功

2019-01-16 09:34:53

登电集团铝加工有限公司新上马的一台¢360/960×1450mm冷轧机于9月份试车成功,10月份将步入正常生产阶段。  该公司于1997年开始筹建,拥有¢680×1600mm铸轧机两台,¢1000×1850mm铸轧机两台,¢380/1050×1800mm四重不可逆全液压冷轧机一台,年生产板、带、箔能力可达6万吨。公司原有的¢380/1050×1800mm冷轧机生产品种单一,不能满足用户的需求,尤其是生产窄料时成本高,降低了公司的利润空间。为了满足用户要求,公司决定新上一台¢360/960×1450mm冷轧机,专门生产窄料。公司在流动资金十分困难的情况下,多方筹措资金,克服重重困难,在2006年5月份开始安装¢360/960×1450mm冷轧机,7月底安装结束,创造了国内轧机安装较短时间之较。这台轧机主机电机功率大,冷却系统全部采用水冷式冷却,较大的轧制力可减少轧制道次,能够提高生产率,有效降低了窄料的生产成本。    该轧机设计轧制较薄厚度为0.08mm,试车时轧制到了0.06mm。目前,正计划投入使用,以后将以生产PS版基坯料为主。该轧机的投产,对产品的多元化、调整产品结构及新产品开发有着积极的推进作用,将会为铝加工公司创造一个新的经济增长点。

电解锰是用锰矿石经酸浸出获得锰盐,再送电解槽电解析出的单质金属。外观似铁,呈不规则片状,质坚而脆,一面光亮,另一面粗糙,为银白色到褐色,加工为粉末后呈银灰色;在空气中易氧化,遇稀酸时溶解并置换出氢,在略高于室温时,可分解水而放出氢气。作用  电解锰的纯度很高,它的作用是增加合金属材料的硬度,应用最广的有锰铜合金、锰铝合金,锰在这些合金中能提高合金的强度、韧性、耐磨性和耐腐蚀性。价格主要影响因素  电解锰的价格主要受供求关系,电力及原料的影响。由于电解锰生产厂商普遍集中在南方,这里通常靠水利发电,因此丰水季和枯水季对电力影响颇大,与电解锰的生产也相关紧密。通常每年4-10月份雨水充足,电力情况较好,生产比较正常。其它月份由于雨量降低导致电力紧张,工厂产量也会相应减少。电解锰与不锈钢  在炼钢生产中,电解锰特别适合冶炼合金化元素含有总量10%以上的不锈钢、耐热钢、精密钢、高温钢、耐蚀钢等“特、精、高”合金钢和冶炼低杂质、低有害元素的纯净钢(∑P、S、O、N、H≤100ppm)、趋纯净钢(∑P、S、O、N、H≤200ppm)等钢种。据我国不锈钢、高合金钢和优质钢等特钢的产量及耗用电解锰水平,2004年中国不锈钢等优特钢冶炼消耗电解锰约16万吨左右;其中铬锰系不锈钢耗用8万吨左右,铬锰不锈钢冶炼中超量、非正常耗用2—3万吨;铬镍系不锈钢、铬系不锈钢、耐热不锈钢、精密合金钢、高温合金钢、耐蚀合金钢和其它优特钢等钢种消耗约5万吨左右。   根据我国国民经济和钢铁工业宏观发展走势,2005年乃至未来一段时间不锈钢等优特钢产业正处于上升时间,国内不锈钢产业、产能、产量和市场需求正在高速发展,不锈钢等高端产品优特钢冶炼对电解锰的需求,总体依然保持强劲。同时,随着钢铁企业进一步加大钢材品种结构调整和优化升级,未来我国不锈钢、优特钢等高附加值、高技术含量的高品质钢材产量将会有较大幅度增长,无疑电解锰在高品质钢种冶炼中的耗用量也将有比较大的增量空间。   要很好把握电解锰行业的发展,下游厂家的情况自然是息息相关。除200不锈钢之外,电解锰还用于生产特钢和优钢,其中特钢也可用锰锭或较便宜的高碳锰铁。全球每年特钢生产要用电解锰7-8万吨,锰铝合金用锰约1-2万吨,Mn3O4等磁性材料用锰约5-6万吨,全球总需求约45-50万吨左右,国内需求约15-20万吨。更多关于电解锰的用途的信息和资讯,请继续关注我站锰频道!

电解锰的概念及其用处介绍

2019-09-16 16:12:45

金属锰的提炼办法首要有热法(火法)和电解法(湿法)两种,热法出产(金属锰)纯度不超越95~98%,而纯的金属锰则是由电解法制备(电解金属锰),其纯度可达99.7~99.9%以上。现在,电解法出产已成为金属锰出产的首要办法。电解金属锰是用锰矿石经酸浸出取得锰盐,再送电解槽电解分出的单质金属。外观似铁,呈不规则片状,质坚而脆,一面亮光,另一面粗糙,为银白色到褐色,加工为粉末后呈银灰色;在空气中易氧化,遇稀酸时溶解并置换出氢,在略高于室温时,可分解水而放出氢气。Mn+H2O(热)=Mn(OH) 2+H2↑锰在电动序中坐落氢之前,故易溶于酸,甚至醋酸也能使它溶解而放出氢气,一起生成Mn2+离子。Mn+2HCl=MnCl 2+H2↑Mn+H2SO4 (稀)=Mn SO4+H2↑3Mn+8HNO3 (稀)=3Mn (NO3) 2+2NO↑+4H2O商标电解金属锰按其锰及杂质含量的不同分为四个商标商标&Nbsp;        化学成分%        Mn         C         S         P         Si         Fe         Se                                                I         Ⅱ               不小于         不大于DJMn99.9        99.9                                                      DJMn99.8         99.8         0.02         0.03         0.005         0.005         0.01         0.03         0.06DJMn99.7         99.7         0.04         0.05         0.005         0.01         0.01         0.03         0.1DJMn99.5         99.5         0.08         0.1         0.01         0.015         0.05         0.15效果电解锰的纯度很高,它的效果是添加合金属材料的硬度,运用最广的有锰铜合金、锰[url=#]铝合金[/url],锰在这些合金中能进步合金的强度、耐性、耐磨性和反抗腐蚀才能。运用领域锰及锰合金是钢铁工业、铝合金工业、磁性材料工业、化学工业等不行短少的重要质料之一。锰是锻炼工业中不行短少的添加剂,电解锰加工成粉状后是出产[url=#]四氧化三锰[/url]的首要质料,电子工业广泛运用的磁性材料原件便是用四氧化三锰出产的,电子工业、冶金工业和航空航天工业都需求电解金属锰。跟着科学技术的继续不断的开展和出产力水平的逐渐的提高,电解金属锰因为它的高纯度、低杂质特色,现已成功而广泛地运用于钢铁锻炼、有色冶金、电子技术、化学工业、环境保护、食品卫生、电焊条业、航天工业等各个领域,国内电解锰主产区状况在我国的电解锰工业中,[url=#]湖南[/url]、[url=#]贵州[/url]、重庆接壤的锰三角是见义勇为的会集地,因为开发早和开展快,现在锰矿在秀山、松桃现已供给严峻,再加上当地政府重复征收资源补偿费、出县要收几十元/吨,矿石价格占到电解锰本钱的1/3。重庆、松桃、湘西的矿山都存在乱采乱挖的现象,几万吨储量现在只剩一半,并且资源回收率很低,只要50%左右,挖掘中采富弃贫现象严峻,矿石档次从19%下降至16%。但广西的矿石供给丰厚,大新的储量有一亿吨,够几十年运用。价格首要影响要素电解锰的价格首要受供求关系,电力及质料的影响。因为电解锰出产厂商遍及会集在南边,这儿一般靠水利发电,因而丰水季和枯水季对电力影响颇大,与电解锰的出产也相关严密。一般每年4-10月份雨水足够,电力状况较好,出产比较正常。其它月份因为雨量下降导致电力严峻,工厂产值也会相应削减。出产的根本工艺现在,我国电解金属锰出产首要以99.7%的产品为主(现大部分厂家实践已达到99.8%以上),只要少量几个厂家出产99.9%的产品(因99.9%的产品商场需求量较小,但许多企业在作可行性研究报告时都声称出产99.9%的),首要原材料-锰矿为氧化锰矿和碳酸锰矿两大类,除前工序制液办法不尽相同外,电解出产的根本工艺根本相同。碳酸锰矿是直接运用[url=#]硫酸[/url]与碳酸锰化合反响制取硫酸锰溶液,再经过中和、净化、过滤等一系列工艺制备为电解液,经参加添加剂如二氧化硒等即可进入电解槽进行电解;运用二氧化锰出产电解锰的工艺与用碳酸锰出产的根本工艺有所不同,首要是二氧化锰在一般条件下不与硫酸反响,必须经处理为二价锰后再与硫酸反响制备硫酸锰溶液,其处理办法一般为焙烧法,是将二氧化锰与复原性物质(一般为煤炭)一起混合后密闭加热,在必定温度下C将四价锰复原为二价锰,破坏后与硫酸反响,这种办法称为焙烧法;另一种办法是称为两矿法的,便是用二氧化锰矿粉和硫铁矿在硫酸效果下发作氧化复原反响来制备硫酸锰。不过这两种办法因为本钱较高,业界根本不与选用,其间,焙烧法较之于两矿法更为遍及,但因为许多的焙烧出产厂运用的焙烧炉是简略易制但能耗较高污染较大的反射炉,前几年,国家发改委已明令撤销反射炉用于出产电解锰出产的根本工艺。电解锰与不锈钢在炼钢出产中,电解锰特别合适锻炼合金化元素含有总量10%以上的不锈钢、耐热钢、精细钢、高温钢、耐蚀钢等“特、精、高”合金钢和锻炼低杂质、低有害元素的纯洁钢(∑P、S、O、N、H≤100PPm)、趋纯洁钢(∑P、S、O、N、H≤200ppm)等钢种。据我国不锈钢、高合金钢和优质钢等特钢的产值及耗用电解锰水平,2004年我国不锈钢等优特钢锻炼耗费电解锰约16万吨左右;其间铬锰系不锈钢耗用8万吨左右,铬锰不锈钢锻炼中过量、非正常耗用2—3万吨;铬镍系不锈钢、铬系不锈钢、耐热不锈钢、精细合金钢、高温合金钢、耐蚀合金钢和其它优特钢等钢种耗费约5万吨左右。根据我国国民经济和钢铁工业微观开展走势,2005年甚至未来一段时间不锈钢等优特钢工业正处于上升时间,国内不锈钢工业、产能、产值和商场需求正在高速开展,不锈钢等高端产品优特钢锻炼对电解锰的需求,整体仍然坚持微弱。一起,跟着钢铁企业进一步加大钢材种类结构调整和优化晋级,未来我国不锈钢、优特钢等高附加值、高技术含量的高品质钢材产值将会有较大起伏增加,无疑电解锰在高品质钢种锻炼中的耗用量也将有比较大的增量空间。要很好掌握电解锰职业的开展,下流厂家的状况自然是休戚相关。除200不锈钢之外,电解锰还用于出产特钢和优钢,其间特钢也可用锰锭或较廉价的高碳锰铁。全球每年特钢出产要用电解锰7-8万吨,锰铝合金用锰约1-2万吨,Mn3O4等磁性材料用锰约5-6万吨,全球总需求约45-50万吨左右,国内需求约15-20万吨。

锰价格走势

2017-06-06 17:49:52

锰价格走势,近期电解锰主流出厂含税报价下降至11500-11600元/吨,由于之前其价格差距较大的报价有11300-12000元/吨,但是主流价多保持在11800-12000元/吨左右。其价格下调的原因可归纳如下:首先,是出口数量的减少形成出口市场有价无市的局面。其次,价格过低的企业多数都已停产或者是没有现货的。宏观方面:2009年3月27日 ,财政部、国家税务总局发布了《关于提高轻纺电子信息等商品出口退税率的通知》,明确从2009年4月1日起提高纺织品、服装、轻工、电子信息、钢铁、有色金属、石化等商品的出口退税率,其中涉及部分钢铁、有色金属、合金材料等,由此在钢铁市场及钢铁原料市场引起较大反响,关注此举对未来国内钢市和钢铁原料市场带来影响。从财政部、国家税务总局公布的提高出口退税率的商品清单看,提高部分钢材出口退税率的主要有冷轧卷材、热轧不锈钢卷板、不锈钢热轧条、杆、取向性硅电钢宽板、冷轧其他合金钢板材、高速钢的条、杆、冷轧不锈钢制的无缝管、非冷轧(拔)不锈钢制无缝锅炉管、精密焊缝管等,其退税率提高到13%。提高出口退税率的还有合金材料,其中的合金镍条、杆、型材,合金镍丝,合金镍管,铝合金制空心异型材,其他铝合金制型材、异型材,其他钽丝,其他锻轧钽及其制品,钛合金,实心圆柱体,包括锻件等,出口退税率为9%-13%。业内人士认为,这次提高部分钢材出口退税率的大都是高附加值产品,以优特钢、合金钢、高速钢和不锈钢为主,而这类钢材的所消费的合金量较大,比如冶炼不锈钢需要铬、镍、钼等特种合金,高速钢主要是合金有铬、锰,钨、钼、钒等,合金钢板材更需要大量的合金。因此,这类钢材提高出口退税率,将拉动合金的需求。加上,此次提高出口退税率中还有合金镍条、杆、型材,合金镍丝,合金镍管,其出口退税9%-13%。如果随着出口退税率的提高,这类钢材的出口增加,对特种合金市场的走稳也是有利的。也就是说作为特种合金的锰系合金也有可能会受惠,本身既是炼钢原料又是中低碳锰铁的原料的电解锰无疑能搭上这趟顺风车,照理来说价格上应该是上调的。不少电解锰厂家也表示,他们希望此次钢材出口退税的提高能够对电解锰的价格产生积极的影响。不过,据一些业内人士分析,这次提高部分钢铁产品出口退税率没有达到预期目标,预期的对冷板等高附加值产品的出口退税上调至17%,而公布的是13%,而热轧板出口退税继续持续零税率,所以说,调整幅度不太大。对国内钢材市场带来的影响有限。再说,特种合金需求量大的不锈钢、高速钢、合金钢等,原本出口量就不多,即便提高出口退税率,不锈钢、优特钢等合金钢的出口量也不可增加。而且这次出口退税调整,宽度小于600毫米的不锈钢窄带类商品被排除在外,而不锈钢窄带厂家正好是国内电解锰需求的主要客户,就这点而言,可以说出口退税对电解锰的价格产生积极影响的效果有限。成本方面,随着第一季度电价政策的调整,目前电解锰生产地区电价不一,主产区从0.42元/度到0.53元/度的电价都有存在;二季度本身为丰水期,湖南地区采取在去年第四季度的用电量上多用电多优惠的政策鼓励电解锰企业用电,去年第四季度电解锰厂家基本上是全线生产,而目前部分厂家已经停产,加上开工的厂家也是维持低量生产。要想在电价上享受更多的优惠政策上肯定是没有得到理想的结果。湖南地区17度碳酸锰粉价格则在600元/吨左右,厂家希望矿石价格能继续下滑,但是这个想法得基于电解锰厂家停产数量达到一定规模之后,按照现在的停产数量,锰矿石价格大幅下跌的可能性很小。二氧化硒价格维持在245-255元/千克;根据二氧化硒厂家的表述,目前利润已经处于最低点或是少许亏损,有贸易商已经以240元/公斤的价格一口气买了8吨,有抄底的想法在里面。硫酸方法电解锰产地的硫酸价格变动不大,都维持在300元/吨左右, 在3月份,除了碳酸锰矿石价格有所下降之外,其他原料价格和电解锰的走势一样,基本上保持不变。据了解,由于地区不一样,在政策方面享受的待遇不一样,而企业生产的生产工艺也有差别,现在的成本区间在11000-12000元/吨,无矿企业的成本更高,个别地区以退税的方式补贴电解锰生产厂家,具体数目是200元/吨,这就可以解释为什么厂家普遍在喊成本高时有部分厂家依然正常生产。就已现在12300元/吨的成交价格来说,有的地区总体上还是有利润可挣,有的地区的确是处于亏损状态,这也是为什么价格一样,有的电解锰厂家选择停产,有的停产厂家选择恢复生产的原因,另外在厂家的实际生产和销售过程中,有一个亏损平衡点,就是按照现行价格生产虽然会亏,但是亏损的额度比停产要好一点。想在的市场价恰好就处在这样一个平衡点上。因而从成本方面来看第二季度的电解锰的成本变化不大。其次需求方面难以有好转出口方面,据海关统计数据显示,今年1-2月份中国共出口电解锰15913吨,同比下滑58.8%,相应出口价值也下滑65.1%,为3980万美元。3月份的出口数据虽然还没有统计出来,但是从专门从事电解锰出口的贸易商处获悉,3月份整体询盘较少,价格大幅下滑。 随着经济危机的深度蔓延,欧洲、美国、日本等经济发达国家及地区今年一、二季度的钢铁产量继续减少,部分地区的减产幅度甚至达到30%-50%,这主要是由于汽车及制造等相关行业的减产使其对钢铁的需求大幅减少。需求低迷、消耗减少导致全球铁合金产品的库存压力较大,特别是欧洲、美国、日本等发达国家和地区,部分铁合金品种的库存可使用3个月甚至半年的时间。另外欧洲钢铁工业联盟表示,自去年第四季度以来,欧洲钢铁工业的需求开始崩溃;订单减少了57%,预计今年第一季度和第二季度表观消费分别下降30%和16%;产能利用率平均下降了30%,钢铁价格已下降了50%。7.2万人已失业或转为短期工,占欧盟钢铁行业雇员总量的17%。可见第二季度电解锰的出口方面依然受到国外钢铁行业需求的制约,情况不容乐观。国内需求方面:从民营钢厂3月份减产情况可见,主流13家民营钢厂在3月份实施减产的有福建吴航、浙江友谊、内蒙古华业、西南不锈钢、佛山诚德等,华光与青山也有减产行为;主流民营钢厂3月份总产量预计累计减产6万吨左右;而在4月份主流钢厂减产或将进一步维持,青山金汇有计划减产约1万吨、吴航计划将继续保持2万吨以内的产量。大钢厂方面,联众方面在4月份将加大L1系列的产量,预计增产10-20%左右,宝钢也进军200系,量虽然不大,却不能否认这是一个还算利好的消息,不是但从这些钢厂的招标价格来看,钢厂接受价格较低,3月初的宝钢招标价为12500元/吨到厂,折算成出厂价就是12100元/吨到12200元/吨的出厂价。就整体而言,为了达到需求和产量的相对平衡,200系不锈钢减产情况比较明显。就不锈钢而言,四月份电解锰价格应该还有下行的压力。而从中低碳锰铁方面来看,情况依然不容乐观。按照以往矿价走势规律的分析来看,在第二季度锰矿价格则可能出现进一步调整,并于三季度达到全年最低水平。业内分析人士预计,2009年的锰矿价格将会调整至与2007年二三季度的价格水平相当,库存方面,在亚洲铁合金会议上,有专业专家表示中国市场中现存的大量锰铁仍足以支撑国内钢铁企业使用一个季度甚至更长时间;国际市场中的库存同样需要两个月以上的时间来消耗,因而四五月份,无论是中国还是亚洲,乃至全球市场,锰铁的交易价格仍将继续下走,钢厂减产,矿石价格下调,再加上库存较多,锰系合金存在相当大的下调空间。周遭一片跌势,电解锰独善其身难度可见。更多关于锰价格走势的信息和资讯,请继续关注本站锰频道!

当日镍价

2017-06-06 17:49:56

今日无锡市场延续昨日的跌势,今日市场早间报价在昨日价格基础上再调低200-300元/吨左右,主要原因是昨日成交的不利以及当日镍价的持续下跌;此外,早上我网了解到的信息得知,虽受成交和镍价的拖累,但仍有商家维持之前的报价,商家之意亦是暂时减少出货或不想出货,当然这不能算是市场主流状况。今日无锡304系列的报价具体状况:热轧方面,卷板基价(5.0mm1500mm)报价如下,太钢资源报在21200元/吨左右,跌300元/吨左右,宝钢资源报在21600元/吨左右,下调200元/吨左右,张浦资源均报在21600元/吨左右,跌200元/吨左右;冷轧方面,卷板基价(2.0mm1219mm)报价如下,太钢资源报在22200元/吨左右,跌200元/吨左右,张浦资源报在22400元/吨左右,下调300元/吨左右,宝新资源报在22300元/吨左右;跌200元/吨左右。钢厂方面:今日主要集中在联众方面,昨日联众钢厂所报的盘价中304系列冷热轧产品均上调300元/吨;不过根据市场反馈的消息,目前联众的价格策略产生的效果甚微,或许是目前的跌势环境造成较大影响的缘故,不少采购商观望心态较浓。资源方面:仍旧主要是热轧方面,从目前的局面看来,短时间内难以改变目前热轧资源的状况,这从不少商家对东方特钢、以及酒缸资源的依赖可以大概推断出;冷轧方面,某些薄规格仍就存在供应偏紧状况,暂时还没有过度的紧缺,不过随着钢厂持续实施限制投放量的政策,或许后期会存在异常状况,但还要看下游的采购幅度。原料方面:昨夜伦镍盘中受到欧美股市暴跌的较大拖累和影响,导致镍价继续呈现震荡下跌的行情,并最终使价格在10日均线下方收盘,走势不太理想。我网分析师认为,由于伦镍昨夜出现的下跌破位走势,使得镍价近期的调整压力逐渐有所增加。因此,如果短期伦镍无法强势反弹夺回上方均线支撑,那么说明市场对于中期压力的突破失败,镍价或将还存在一定的震荡调整要求,建议投资者需开始保持一定的谨慎心态。市场方面:首先是市场上的卖家,即市场商家,受成交和镍价的下跌影响,304系列商家不得不再次下调价格,略显被动;不过成交方面,今日状况超过昨日,不少商家反应还可以。其次,市场上的买家,即采购商,虽然304系列的价格连续两日下调,但是当前情况下,采购的积极性仍然不是很高,观望的心理仍旧存在。宏观经济方面,本周主要有以下几个方面的焦点:(1)欧盟区,英国央行在周三公布的季度通胀报告中下调了明年的经济增长预期,并上调了明年通胀预期,经济复苏不太理想。(2)亚太区,我国今年的宏观经济面临的困难不少,经济增长预期可能会下调;此外,日本央行可能采取额外松动措施以抑制通缩风险和支持经济复苏。(3)美元区,美国经济和就业复苏步伐有所放缓,短期内经济复苏很可能较此前预期更为疲软,美联储考虑将采取“量化宽松”货币措施;此外,美国六月份的贸易数据亦是不甚理想。综合当日镍价考虑以上因素,根据最近无锡304系列的状况和走势,个人认为,近期无锡304系列或仍将以小幅度调整波动为主,但不排除其它状况的意外出现;以上仅为个人观点,建议市场酌情把握,谨慎操作。

电解锰行情

2017-06-06 17:49:52

金属锰行情,近来,金属锰市场价格回升。2月10日,伦敦金属交易所牌号99.7%的金属锰现货价格每吨从818-875美元升至880-930,吨价上升65美元;2月14日,英国《金属导报》99.7%的金属锰报价从850-925美元/吨涨至900-1000美元/吨,吨价也上涨了65美元。目前华东地区属锰Jmn95-A吨价升至9850元,99.7%从10100元升至10500元;天津市场99.7%升至11000元;西安地区有的高达12500元。金属锰吨价升幅500元左右。品名规格钢厂/产地出厂含税价(元/吨度涨跌备注相关资源电解金属锰DJMn99.7湖南14800-15000--查看电解金属锰DJMn99.7重庆14800-15000--查看电解金属锰DJMn99.7广西14800--查看电解金属锰DJMn99.7贵州14800-15100--查看电解金属锰DJMn99.7宁波15300-15400--查看金属锰锭97#湖南15900-16100--查看金属锰是生产优质合金钢、奥氏体不锈钢及有关高附加值钢材的添加剂和脱氧剂之一。前两年,我国金属锰出口量大,年增长率10%左右,2000年的出口量高达9万吨,主要出口到欧亚地区。仅日本2001年的进口量就高达4万吨。由于国际市场竞争激烈,金属锰价格一度走低,2001年上半年国际市场每吨高达1325美元,而同年12月降至900-1050美元,2002年第三季度又降至800-875美元。    为何今年金属锰价格一直稳中有升呢?据分析,主要因素大致有以下几点:    一是锰矿价格有所反弹。2002年12月份,国际市场锰矿价格出现上涨。12月份,我国进口锰矿23.5万吨,平均单价为81.87美元/吨,比上个月分别上涨了57.4%和14.8%,锰矿价格每吨比去年7月几乎上涨了10美元;加之相关地区电价上涨,必然提升了金属锰的生产成本。    二是海运费上涨。由于海湾战争一触即发,国际石油价格飙升,国际海运费大幅上涨。市场界估计,2003年1月巴拿马船运费从每天1.1万美元提高到1.5万美元。锰矿运费必然上升。    三是金属锰需求增长。有消息称,今年美国经济将增长3.25-3.5%,高于去年的2.4%,因而美国钢铁业尤其特钢行业和不锈钢行业将有明显的增长。2002年日本特钢产量为1714万吨,同比增长8.2%;特钢出口580万吨,同比增长23%。预计2003年一季度日本特钢产量将达440万吨,同比增长11.4%。此外,预计今年我国经济仍将保持7%-8%的增长速度,全年特钢产量增长将达10.5%。据专家预测,2003年优质钢材的产量将达1650万吨,其中高附加值的汽车用钢材增长30-40%、机械行业用钢增长15%、轴承、合金钢需求增长10%以上;此外,集装箱用钢、弹簧钢、高工钢等均有一定幅度的增长,这将拉动对金属锰的需求。    四是不锈钢行业将增加对金属锰的需求。随着不锈钢消费品种发生变化,一种含锰低镍的不锈钢产品日益受市场青睐。据专家介绍,200系列奥氏体不锈钢已是国内大力开发的好钢种,其性能好,具有耐腐蚀性强、使用寿命长的特点。在冶炼中提高锰的含量并加入氮着两个元素代替镍,可使镍的含量降低至2.5-5%。由于成本低,在镍资源紧张、价格高昂的形势下,200系列不锈钢将在中国得到大力推广。目前,世界上80%的奥氏体产于印度,特别是在农民中普及程度比我国要高。专家认为,从不锈钢的发展和应用角度看,我国和印度有很多相似之处:两国都是发展中国家,农业人口都占总人口80%以上;两

资料来源:中国产业分析平台     2008年钢铁行业的在建项目规模有明显减小,这主要是由于前两年钢铁行业处于高度景气周期,产能急剧扩张;今年钢铁行业面临的压力加大,造成了产能扩张速度的明显回落。预计未来钢铁行业的供给增速将会有所放缓。     四、供给预测     从钢铁行业固定资产投资情况和已形成的产能情况分析,目前,中国已具备年产5.7亿吨粗钢的生产能力。钢铁生产能力能否充分发挥出来,主要取决于宏观环境和外部条件。影响钢铁产能发挥的主要有五大制约因素:一是受铁矿石、煤炭、焦炭、石油价格大幅上涨的制约;二是受国家淘汰落后产能制约;三是受电力、运输紧张的制约;四是受资金面紧张的制约;五是受市场需求减少的制约。     2008年以来,国内粗钢产量同比增速明显下滑,2008年1-9月粗钢产量3.91亿吨,同比增速6.20%,如果按照前9个月的平均产量计算,预计全年粗钢产量约为52100万吨,只比上年增长6%左右,将后期的限产因素考虑进去,预计全年国内粗钢产量在50500万吨,同比增长3%左右,低于2007年增速,2009年、2010年粗钢产量增速将维持低速增长。     同理,按照前8个月的平均产值计算,预计全年钢铁行业工业产值约为46154亿元,同比增长37.12%。如果考虑后期产量减少,则工业产值将在44000亿元左右,同比增长30%左右。     2008年全国粗钢产量的下滑主要原因是中小钢铁企业的产量增速下滑速度明显;下半年钢材需求下降,钢厂限产、停产情况增多;而分区域来看,产钢大省如河北等省市的粗钢产量增速大幅下滑。 表9  钢铁行业产值预测表

合金钢管

2017-07-04 14:48:08

合金钢管用途合金钢管主要用途是用于电厂,核电,高压锅炉,高温过热器和再热器等高压高温的管道上及设备上,它是采用优质碳素钢,合金结构钢和不锈耐热钢做材质,经热轧(挤、扩)或冷轧(拔)而成。优点可以100%回收,符合环保、节能、节约资源的国家战略,国家政策鼓励扩大高压合金管的应用领域。目前我国合金管消费量占钢材总量的比重仅为发达国家的一半,合金管使用领域扩大为行业发展提供更广阔的空间。根据中国特钢协会合金管分会专家组的研究,未来我国高压合金管长材的需求年均增长可达10-12%。与无缝管的联系和区别合金管是钢管按照生产用料(也就是材质)来定义的,顾名思义就是合金做的管子;而无缝管是钢管按照生产工艺(有缝无缝)来定义的,区别于无缝管的就是有缝管,包括直缝焊管和螺旋焊管。标准合金管具有中空截面,大量用作输送流体的管道,如输送石油、天然气、煤气、水,机械加工,及某些固体物料的管道等。合金钢管与圆钢等实心钢材相比,在抗弯抗扭强度相同时,重量较轻,合金钢管是一种经济截面钢材,广泛用于制造结构件和机械零件,如石油钻杆、汽车传动轴、自行车架以及建筑施工中用的钢脚手架等。用合金钢管制造环形零件,可提高材料利用率,简化制造工序,节约材料和加工工时,如滚动轴承套圈、千斤顶套等,当前已广泛用钢管来制造。合金钢管还是各种常规武器不可缺少的材料,枪管、炮筒等都要钢管来制造。合金钢管按横截面积形状的不同可分为圆管和异型管。由于在周长相等的条件下,圆面积最大,用圆形管可以输送更多的流体。此外,圆环截面在承受内部或外部径向压力时,受力较均匀,因此,绝大多数钢管是圆管。合金管有大口径合金管,厚壁合金管,高压合金管,合金法兰,合金弯头,P91合金管和无缝钢管,另外化肥专用管也非常常见。
