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)

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 、

热轧特点

2018-12-20 09:35:44

热轧特点是:  (1)热轧能显著降低能耗,降低成本。热轧时金属塑性高,变形抗力低,大大减少了金属变形的能量消耗。  (2)热轧能改善金属及合金的加工工艺性能,即将铸造状态的粗大晶粒破碎,显著裂纹愈合,减少或消除铸造缺陷,将铸态组织转变为变形组织,提高合金的加工性能。  (3)热轧通常采用大铸锭,大压下量轧制,不仅提高了生产效率,而且为提高轧制速度、实现轧制过程的连续化和自动化创造了条件。  (4)热轧不能非常精确地控制产品所需的力学性能,热轧制品的组织和性能不能够均匀。其强度指标低于冷作硬化制品,而高于完全退火制品;塑性指标高于冷作硬化制品,而低于完全退火制品。  (5)热轧产品厚度尺寸较难控制,控制精度相对较差;热轧制品的表面较冷轧制品粗糙Ra值一般在0.5~1.5μm。因此,热轧产品一般多作为冷轧加工的坯料。

热轧镀锌

2017-06-06 17:50:08

热轧、镀锌是钢材的两种加工工艺方法,他们的原理完全不同。热轧(hot rolling)是相对于冷轧而言的,冷轧是在再结晶温度以下进行的轧制,而热轧就是在再结晶温度以上进行的轧制。热轧的优点:采用热轧可以提高生产效率、轧制速度,实现轧制过程的连续化和自动化;热轧能降低耗能和降低成本;热轧的 金属 塑性高,变形抗力低;能改善 金属 加工性能,消除铸造缺陷。热轧的缺点:非 金属 物被压会出现分层现象,使受压性能恶化;刚才的长宽尺寸不能控制,产品的精度不够;热轧的不均匀冷却会造成残余应力,变形、稳定性、抗疲劳性能会发生变化。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

钢材镀锌

2017-06-06 17:50:06

钢材镀锌是提高钢材耐锈蚀性能、装饰美观的一种工艺手法。目前,最常用的钢材镀锌方法是热镀锌。钢材(Steel):是钢锭、钢坯或钢材通过压力加工制成所需要的各种形状、尺寸和性能的材料。钢材是国家建设和实现四化必不可少的重要物资,应用广泛、品种繁多,根据断面形状的不同、钢材一般分为型材、板材、管材和 金属 制品四大类、为了便于组织钢材的生产、订货供应和搞好经营管理工作,又分为重轨、轻轨、大型型钢、中型型钢、小型型钢、钢材冷弯型钢,优质型钢、线材、中厚钢板、薄钢板、电工用硅钢片、带钢、无缝钢管钢材、焊接钢管、 金属 制品等品种。钢是含碳量在0.04%-2.3%之间的铁碳合金。为了保证其韧性和塑性,含碳量一般不超过1.7%。钢的主要元素除铁、碳外,还有硅、锰、硫、磷等。钢材 有色金属 又称非铁 金属 ,指除黑色 金属 外的 金属 和合金,如铜、锡、铅、锌、铝以及黄铜、青铜、铝合金和轴承合金等。另外在工业上还采用铬、镍、锰、钼、钴钢材、钒、钨、钛等,这些 金属 主要用作合金附加物,以改善 金属 的性能,其中钨、钢材钛、钼等多用以生产刀具用的硬质合金。以上这些 有色金属 都称为工业用 金属 ,钢材此外还有贵重 金属 :铂、金、银等和稀有 金属 ,包括放射性的铀、镭等钢材。中国钢材需要的政策面固然很踊跃,然而产能过剩不是在2010年就可以处理的成绩。只需产能过剩使不得无效处理,只管出什么样的计划,不落到实处,在弱势需要的条件下,钢材 价格 很难有大的走强的态势涌现。但钢材镀锌后 价格 完全不同,结合镀锌所带来的优势,镀锌钢材 价格 有望走上坡。

热轧带钢

2019-03-18 10:05:23

一般他们的规格标准写成(厚度*宽度*C,C表示长度,由于一般卷起来所以用C表示,如果是矩形钢就会有长度)例如我们所看到的瑞丰带钢2.5*315*C,武钢热卷11.5*1500*C,其中315和1500表示宽度为315mm和1500mm,由此我们认定带钢和热卷的区别在于带钢宽度在1000mm以下,所以能通过规格一眼区分瑞丰的带钢和武钢的热卷,至于为什么有人用带钢有人用热卷,那要看他们厂的轧机能扎什么宽度,由此需求也有所不同。至于楼下提到的Q235是指此钢材能在接受235兆帕的压强之下不变形,用来表示钢材的材质,同理Q195也自然是在195兆帕的压强下不变形。 热轧带钢 2.1 带钢热连轧机的紧凑化布置   带钢热连轧机主要有全连续式、半连续式、3/4连续式三种布置形式,它们的区别集中在粗轧区。全连续式带钢热连轧机的主要特点是轧机均为不可逆轧机,带钢在粗轧区轧制时,每架轧机只按板坯的前进方向轧制一道,并且不形成连轧;半连续式带钢热连轧机的主要持点是至少有一架可逆式轧制,带钢在粗轧区内采用可逆式轧制,进行多道次压下,在粗轧机组不形成连轧;3/4连续式带钢热连轧机的主要特点是带钢在粗轧区部分轧机采用可逆式轧制,而在最后的两架粗轧机内形成连轧。  全连续式带钢热连轧机自动化程度高、产量高,但设备多、投资大,轧制流程长,因此轧件热量损失过多,不利于保温、抢温轧制。特别是在生产过程中,由于每架轧机只轧一道次,使得粗轧机大部分时间处于闲置状态,因此设备利用率过低。为此,广泛采用半连续及3/4连续式带钢热连轧机,节约设备投资,提高粗轧机组的利用率,并缩短轧线长度,减少轧件的热量损失。近年来,由于粗轧机控制水平的提高和轧机结构的改进,轧机牌坊强度增大,轧制速度也相对提高,粗轧机单机架生产能力增大,轧机产量已不受粗轧机产量的制约,因此,半连续式粗轧机发展较快。但由于可逆式轧机操作维修复杂,能耗大,所以对于年产300万t以上规模的带钢厂,3/4连续式带钢热连轧机成为主流。2.2 AWC立辊短行程控制  板坯在粗轧机组中要经过立辊和水平辊交替轧制,通过立辊的侧压实现宽度控制,但是与轧件中部相比,头尾因没有外端的限制作用,在立轧道次将出现头尾失宽。若不对头尾的失宽现象进行有效的控制,则会对宽度精度和成材率产生不利影响。  有AWC(宽度自动控制)功能的重型立辊轧机是为了适应连铸和有利热轧带钢板坯热装的发展而产生的现代轧机。这类立辊轧机结构先进,主传动电机功率大,侧压能力大,和在轧制过程中对带坯进行调宽、控宽及头尾形状控制,不仅可以减少连铸板坯的宽度规格,而且有利于实现热轧带钢板坯的热装,提高带坯宽度精度和减少切损。  按控制方式不同,AWC分为:轧制力反馈控制(RF—AWC)、前馈控制(FF—AWC)和短行程控制(SS—AWC)。  轧制力反馈控制(RF—AWC)是根据侧压时沿板坯长度方向材料硬度不同,会使立辊轧机产生不同的弹跳量,导致轧制力变化的原理,将测得的轧制力变化,由液压AWC装置快速变更辊缝,从而改变轧制压力,使板坯宽度保持为常数,以便水平轧制后的板坯在长度方向上的宽度均匀。  前馈控制(FF—AWC)是针对板坯在加热炉内加热受水冷滑道影响而产生温度低于其他部位的水印,立辊侧压后进行水平轧制时,水印处的材料宽度大于其他部分的材料宽展,导致长度方向上产生宽度差,侧压时对水印进行跟踪,预设定液压AWC,在水印处加大侧压量,消除水印处产生的多余的宽展量,使水平轧制后的板坯达到设定的宽度值。  短行程控制(SS—AWC)是解决板坯侧压量较大时,金属易向中部或两个角部流动,造成板坯头尾失宽的问题。此外,板坯侧压边部凸起,呈两端小、中间大,水平轧制后又加大头尾失宽,通过液压AWC装置对板坯的头尾进行短行程控制,调节其侧压量,使板坯头尾经水平轧制后趋于矩形,从而使整个板坯在长度方向上的宽度均匀,少头尾切损,提高产品收得率。2.3 中间坯保温技术和边部感应加热技术  粗轧机出口带坯长度可达80~90m,进精轧机轧制过程中,为了减少输送辊道上的温度降,以节约能耗,近年来很多工厂还采用在输送辊道上安置绝热保温罩或补偿加热炉(器)。保温罩内表面附一层吸热温升快、热反射率高的特殊合金层,有效地提高了进入精轧的中间坯温度,从而可降低加热炉出坯温度,提高成材率,节约燃耗。还可提高板带末端温度、减少带钢头尾温差,使板带温度更加均匀,可轧出更宽更薄重量更大及精度性能质量更高的板卷。  带坯在轧制过程中,边部由于散热较快,其温降大于中部温降,温差大约为100℃。边部温差大,在带钢横截面上晶粒组织不均匀,性能差异大,同时,还将造成轧制中边部裂纹和对轧辊严重的不均匀磨损。因此,在精轧机组前对带坯边部进行加热,将温度补偿到与中部温度一致。一般采用电磁感应加热器,可使带坯边部温度提高30~50℃,使带钢横向温度更加均匀,从而减少带钢边部裂纹,以适应轧制薄规格产品和硅钢、不锈钢、高碳钢等特殊品种的钢。

钢材热镀锌

2017-06-06 17:50:07

钢材热镀锌是提高钢材耐锈蚀性能、装饰美观的一种工艺手法。也是目前最常用的钢材镀锌的方法。钢材(Steel):是钢锭、钢坯或钢材通过压力加工制成所需要的各种形状、尺寸和性能的材料。钢材是国家建设和实现四化必不可少的重要物资,应用广泛、品种繁多,根据断面形状的不同、钢材一般分为型材、板材、管材和 金属 制品四大类、为了便于组织钢材的生产、订货供应和搞好经营管理工作,又分为重轨、轻轨、大型型钢、中型型钢、小型型钢、钢材冷弯型钢,优质型钢、线材、中厚钢板、薄钢板、电工用硅钢片、带钢、无缝钢管钢材、焊接钢管、 金属 制品等品种。钢是含碳量在0.04%-2.3%之间的铁碳合金。为了保证其韧性和塑性,含碳量一般不超过1.7%。钢的主要元素除铁、碳外,还有硅、锰、硫、磷等。热镀锌也叫热浸锌和热浸镀锌,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。热镀锌生产工艺流程主要包括:原板准备→镀前处理→热浸镀→镀后处理→成品检验等。热镀锌是由较古老的热镀方法发展而来,自从1836年法国把热镀锌应用于工业以来,已经有170年的历史了。然而近30年来,伴随冷轧带钢的飞速发展,热镀锌工业得到了大规模发展。热镀锌钢材在镀锌钢材 市场 上需求量大,相反电镀锌钢材使用的少,只有部分小企业还在制造电镀锌产品,电镀锌已被禁止。热镀锌钢材包括热镀锌钢管、热镀锌板、热镀锌带钢、热镀锌角钢、热镀锌扁钢等等,这些都是热镀锌钢材产品,之所以对这些产品热镀锌,是为了达到防腐的目的。中国钢材需要的政策面固然很踊跃,然而产能过剩不是在2010年就可以处理的成绩。只需产能过剩使不得无效处理,只管出什么样的计划,不落到实处,在弱势需要的条件下,钢材 价格 很难有大的走强的态势涌现。但钢材镀锌后 价格 完全不同,结合镀锌所带来的优势,镀锌钢材 价格 有望走上坡。

镀锌钢材

2017-06-06 17:50:05

镀锌钢材是一个统称,镀锌钢管、镀锌板、镀锌角钢、镀锌扁钢、镀锌角铁等都属于镀锌钢材。方管,是方形管材的一种称呼,也就是边长相等的的钢管。是带钢经过工艺处理卷制而成。一般是把带钢经过拆包,平整,卷曲,焊接形成圆管,再由圆管轧制成方形管然后剪切成需要长度。一般是50根每包。角钢俗称角铁、是两边互相垂直成角形的长条钢材。有等边角钢和不等边角钢之分。等边角钢的 两个边宽相等。其规格以边宽×边宽×边厚的毫米数表示。如“∠30×30×3”,即表示边宽为 30毫米、边厚为3毫米的等边角钢。也可用型号表示,型号是边宽的厘米数,如∠3#。镀锌板是指表面镀有一层锌的钢板。镀锌是一种经常采用的经济而有效的防腐方法。全世界锌 产量 的一半左右均用于此种工艺。镀锌是为防止钢板表面遭受腐蚀延长其使用寿命。槽钢是截面为凹槽形的长条钢材。其规格以腰高(h)*腿宽(b)*腰厚(d)的毫米数表示,如120*53*5,表示腰高为120毫米,腿宽为53毫米的槽钢,腰厚为5毫米的槽钢,或称12#槽钢。镀锌钢材种类繁多,应用于我们生活中的方方面面,而且镀锌钢材的 价格 也在上涨。首先是因为现在0#锌的 价格 在不断上扬,再加上近几年,我国建筑、家电等 行业 对镀锌干菜需求增长很快, 市场 潜力较大,尤其是近年来随着建筑轻型结构的迅速发展,轿车 产量 的逐年增加,家用电器的广泛普及,合资、独资企业电子产品的大量出口,使镀锌产品的消费量增长较快。目前,国内镀锌钢材的生产无论是数量还是品种均不能满足 市场 需求,每年需要大量进口,国内镀锌钢材生产 市场 占有率较低,国内 市场 供不应求, 市场 潜力巨大。

1、 碳素钢的界说及钢中五元素  含碳2%以下的铁碳合金称为钢。  碳素钢中的五元素是指化学成份中的首要组成物,即 C、Si、Mn、S、P(碳、硅、锰、硫、磷)。其次是在炼钢进程中不可避免地  会混入气体,含O、H、N(氧、氢、氮)。此外,用铝¡硅脱氧冷静工艺中,必定在钢水中含有 Al,当Als(酸溶铝)≥0。020%时,  还有细化晶粒的效果。  2、 钢铁是怎样炼成的?  炼钢的首要任务是按所炼钢种的质量要求,调整钢中碳和合金元素含量到规则规模之内,并使P、S、H、O、N等杂质的含量降至允 许定量之下。  炼钢进程实质上是一个氧化进程,炉猜中过剩的碳被氧化,焚烧成CO气体逸出,其它Si、P、Mn 等氧化后进入炉渣中。S部份进入  炼渣中,部份则生成SO2排出。当钢水成份和温度到达工艺要求后,即可出钢。为了除掉钢中过剩的氧及调整化学成份,能够增加脱氧剂和铁合金或合金元素。  3、 转炉炼钢简介  从车运来的铁水通过脱硫、挡渣等处理后即可倒入转炉中作为首要炉料,另加10% 以下的废钢。然后,向转炉内吹氧焚烧,铁水中的过量碳被氧化并放出很多热量,当探头测得到达预订的低碳含量时,即中止吹氧并出钢。一般在钢包中需进行脱氧及调整成份操作;然后在钢液表面抛上碳化稻壳避免钢水被氧化,即可送往连铸或模铸工区。  对要求高的钢种可增加底吹氩、RH真空处理、喷粉处理(喷SI¡CA粉及变性石灰)能够有用下降钢中的气体与搀杂,并有进一步降碳及降硫的效果。在这些炉外精粹办法后还能够终究微调成份,满意优质钢材的需求。  4、 初轧  模铸钢锭采纳热装、热送新工艺,进入均热炉加热,然后通过初轧机及钢坯连轧机轧成板坯、管坯、小方坯等初轧产品,通过切头、  切尾、表面整理,(火焰整理、打磨)高质量产品则还需对初轧坯进行扒皮和探伤,查验合格后入库。  现在初轧厂的产品有初轧板坯、轧制方坯、氧气瓶用钢坯、齿轮用圆管坯、铁路车辆用车轴坯及塑模用钢等。  初轧板坯首要直销热轧厂作为质料;轧制方坯除部份外供,首要送往高速线材轧机作质料。  因为连铸板坯的先进性,初轧板坯的需求量大为减少,因而转向上述其它产品了。  5、 热连轧  用连铸板坯或初轧板坯作质料,经步进式加热炉加热,高压水除鳞后进入粗轧机,粗轧料经切头、尾、再进入精轧机,施行计算机控制轧制,终轧后即通过层流冷却(计算机控制冷却速率)和卷取机卷取、成为直发卷。直发卷的头、尾往往呈舌状及鱼尾状,厚度、宽度精度较差,边部常存在浪形、折边、塔形等缺点。其卷重较重、钢卷内径为760mm。(一般制管职业喜欢运用。)  将直发卷经切头、 切尾、切边及多道次的矫直、平坦等精整线处理后,再切板或重卷,即成为:热轧钢板、平坦热轧钢卷、纵切带等产品。  热轧精整卷若经酸洗去除氧化皮并涂油后即成热轧酸洗板卷。该产品有部分代替冷轧板的趋向,报价适中,深受广阔用户喜欢。  宝钢新出资的一条热轧酸洗线正在严重建设中。  6、 冷连轧  用热轧钢卷为质料,经酸洗去除氧化皮后进行冷连轧,其制品为轧硬卷,因为接连冷变形引起的冷作硬化使轧硬卷的强度、硬度上升、韧塑目标下降,因而冲压功能将恶化,只能用于简略变形的零件。  轧硬卷可作为热镀锌厂的质料,因为热镀锌机组均设置有退 前方。轧硬卷重一般在6~13.5吨,钢卷内径为610mm。  一般冷连轧板、卷均应通过接连退火(CAPL机组)或罩式炉退火消除冷作硬化及轧制应力,到达相应标准规则的力学功能目标。  冷轧钢板的表面质量、外观、尺度精度均优于热轧板,且其产品厚度右轧薄至0.18mm左右,因而深受广阔用户喜爱。  以冷轧钢卷为基板进行产品的深加工,成为高附加值产品。如电镀锌、热镀锌、耐指纹电镀锌、彩涂钢板卷及减振复合钢板、PVC 复膜钢板等,使这些产品具有漂亮、高抗腐蚀等优秀质量,得到了广泛应用。  冷轧钢卷经退火后有必要进行精整,包含切头、尾、切边、矫平、平坦、重卷、或纵剪切板等。冷轧产品广泛应用于轿车制造、家电产品、外表开关、建筑、工作家具等职业。钢板捆包后的每包分量为3~5吨。平坦分卷重一般为3~10吨/卷。钢卷内径610mm。  7、 钢的力学功能  7.1拉力实验  按标准制备的拉力试样,装置在拉力实验机的夹头内,对试样缓慢施加单轴向拉伸应力,直至试样被拉断停止的实验称作拉力实验。  7.1.1强度  金属材料在外力效果下,反抗变形和开裂的才能叫强度。强度目标包含:份额极限、弹性极限、屈从强度、抗拉强度等。  7.1.2份额极限  对金属施加拉力,金属存在着力与变构成直线份额的阶段,而这个阶段的最大极限负荷Pp除以试样的原横截面积即为份额极限,用 σ P表明。  7.1.3弹性极限  金属受外力效果发作了变形,外力去掉后,能彻底康复本来的形状,这种变形称为弹性变形。金属能坚持弹性变形的最大应力称为弹性极限,用σe表明。  7.1.4抗拉强度  试样拉伸时,在拉断前所接受的最大负荷除以原横截面积所得的应力,称作抗拉强度,用σb表明。当材料所受的外应力大于其抗拉强度时,将会发作开裂。因而σb越高,则表明它能接受愈大的外应力而不致于开裂。  国外标准的结构钢常按抗拉强度来分类,如SS400,其间400即表明σb的最小值为400MPa超高强度钢是指σb≥1373 Mpa的钢。  7.1.5屈强比  屈强比即屈从强度与抗拉强度之比值(σS/σb)。屈从比值越高,则该材料的强度愈高,屈强比值愈低则塑性愈佳,冲压成形性愈好。如深冲钢板的屈强比值为≤0.65。  弹簧钢一般均在弹性极限规模内执役,受载荷时不允许发生塑性变形,因而要求弹簧钢经淬火、回火后具有尽可能高的弹性极限和屈强比值(σS/σb≥0.90)此外疲惫寿数与抗拉强度及表面质量往往有很大干系。  7.1.6塑性  金属材料在受力损坏前能够饱尝永久变形的功能称为塑性。塑性目标一般伸长率和断面缩短率表明。伸长率与断面缩短率越高,则 塑性越好。  8、冲击耐性  用必定尺度和形状的金属试样,在规则类型的冲击实验上受冲击负荷折断时,试样刻槽处单位横截面上所耗费的冲击功,称为冲击 耐性以αk表明。  现在常用的10×10×55mm,带2 mm深的V形缺口夏氏冲击试样,标准上直接选用冲击功(J焦耳值)AK,而不是选用αK值。因为单位面积上的冲击功并无实践意义。  冲击功关于查看金属材料在不同温度下的脆性转化最为灵敏,而实践执役条件下的灾难性破断事端,往往与材料的冲击功及执役温 度有关。  因而在有关标准中常常规则某一温度时的冲击功值为多少、还规则FATT(断口面积转化温度)要低于某一温度的技能条件。所谓FATT,即一组在不同温度下的冲击试样冲断后,对冲击断口进行鉴定,当脆性开裂占总面积的50%时所对应的温度。  因为钢板厚度的影响,对厚度≤10mm的钢板,可获得3/4小尺度冲击试样(7.5×10×55mm)或1/2小尺度冲击试样(5×10×55mm)。可是必定要注意,同规格及同一温度下的冲击功值才可彼此比较。只要在标准规则的条件下,才可按标准的换算办法,折算成标准冲击试样的冲击功,再彼此比较。  9、硬度实验  金属材料反抗压头(淬硬的钢球或具有1200圆锥或角锥的金刚石压头)压陷表面的才能称为硬度。依据实验办法和适用规模的不同,硬度可分为布氏硬度、洛氏硬度、维氏硬度、肖氏硬度以及显微硬度、高温硬度等。  冶金产品常用的是布氏硬度和洛氏硬度。  10、宝钢厂商标准(Q/BQB)  宝钢企标中的钢号大致可分为三个来历即从日本JIS标准、德国DIN标准移植及自行开发研发的钢号。从日本JIS标准中移植来的钢号,一般首位常为S(Steel);从DIN标准移植来的钢号,一般常以ST最初(Stahl德文中的“钢”);宝钢自行开发研发的钢号,一般首位常以宝钢的拼音首位B最初。  11、结构用热连轧、冷连轧钢板及钢带  结构钢一般按强度分类,在钢号中的数字往往代表抗拉强度的最低值。因为该类钢常用于制造结构件,因而称作为结构钢。结构钢的强化机制倾向于降碳增锰固溶强化铁素体、细化珠光体和增加微合金的分出强化、沉积强化和细晶强化,以保证在进步强度的一起仍坚持较好的韧、塑目标并兼具杰出的焊接功能。

钢材力学性能

2019-03-19 09:03:26

钢材力学性能是保证钢材最终使用性能(机械性能)的重要指标,它取决于钢的化学成分和热处理制度。在钢管标准中,根据不同的使用要求,规定了拉伸性能(抗拉强度、屈服强度或屈服点、伸长率)以及硬度、韧性指标,还有用户要求的高、低温性能等。      ①抗拉强度(σb)       试样在钢铁拉伸过程中,在拉断时所承受的最大力(Fb),出以试样原横截面积(So)所得的应力(σ),称为抗拉强度(σb),单位为N/mm2(MPa)。它表示金属材料在拉力作用下抵抗破坏的最大能力。计算公式为:       式中:Fb--试样拉断时所承受的最大力,N(牛顿);       So--试样原始横截面积,mm2。         ②屈服点(σs)       具有屈服现象的金属材料,试样在拉伸过程中力不增加(保持恒定)仍能继续伸长时的应力,称屈服点。若力发生下降时,则应区分上、下屈服点。屈服点的单位为N/mm2(MPa)。       上屈服点(σsu):试样发生屈服而力首次下降前的最大应力;       下屈服点(σsl):当不计初始瞬时效应时,屈服阶段中的最小应力。       屈服点的计算公式为:       式中:Fs--试样拉伸过程中屈服力(恒定),N(牛顿);       So--试样原始横截面积,mm2。           ③断后伸长率(σ)       在拉伸试验中,试样拉断后其标距所增加的长度与原标距长度的百分比,称为伸长率。以σ表示,单位为%。计算公式为:       式中:L1--试样拉断后的标距长度,mm;       L0--试样原始标距长度,mm。       ④断面收缩率(ψ)       在拉伸试验中,试样拉断后其缩径处横截面积的最大缩减量与原始横截面积的百分比,称为断面收缩率。以ψ表示,单位为%。计算公式如下:       式中:S0--试样原始横截面积,mm2;     S1--试样拉断后缩径处的最少横截面积,mm2。          ⑤硬度指标       金属材料抵抗硬的物体压陷表面的能力,称为硬度。根据试验方法和适用范围不同,硬度又可分为布氏硬度、洛氏硬度、维氏硬度、肖氏硬度、显微硬度和高温硬度等。对于管材一般常用的有布氏、洛氏、维氏硬度三种。      A、布氏硬度(HB)       用一定直径的钢球或硬质合金球,以规定的试验力(F)压入式样表面,经规定保持时间后卸除试验力,测量试样表面的压痕直径(L)。布氏硬度值是以试验力除以压痕球形表面积所得的商。以HBS(钢球)表示,单位为N/mm2(MPa)。       其计算公式为:       式中:F--压入金属试样表面的试验力,N;       D--试验用钢球直径,mm;      d--压痕平均直径,mm。       测定布氏硬度较准确可靠,但一般HBS只适用于450N/mm2(MPa)以下的金属材料,对于较硬的钢或较薄的板材不适用。在钢管标准中,布氏硬度用途最广,往往以压痕直径d来表示该材料的硬度,既直观,又方便。       举例:120HBS10/1000130:表示用直径10mm钢球在1000Kgf(9.807KN)试验力作用下,保持30s(秒)测得的布氏硬度值为120N/ mm2(MPa)。       B、洛氏硬度(HK)       洛氏硬度试验同布氏硬度试验一样,都是压痕试验方法。不同的是,它是测量压痕的深度。即,在初邕试验力(Fo)及总试验力(F)的先后作用下,将压头(金钢厂圆锥体或钢球)压入试样表面,经规定保持时间后,卸除主试验力,用测量的残余压痕深度增量(e)计算硬度值。其值是个无名数,以符号HR表示,所用标尺有A、B、C、D、E、F、G、H、K等9个标尺。其中常用于钢材硬度试验的标尺一般为A、B、C,即HRA、HRB、HRC。           硬度值用下式计算:       当用A和C标尺试验时,HR=100-e       当用B标尺试验时,HR=130-e       式中e--残余压痕深度增量,其什系以规定单位0.002mm表示,即当压头轴向位移一个单位(0.002mm)时,即相当于洛氏硬度变化一个数。e值愈大,金属的硬度愈低,反之则硬度愈高。       上述三个标尺适用范围如下:       HRA(金刚石圆锥压头)20-88       HRC(金刚石圆锥压头)20-70       HRB(直径1.588mm钢球压头)20-100       洛氏硬度试验是目前应用很广的方法,其中HRC在钢管标准中使用仅次于布氏硬度HB。洛氏硬度可适用于测定由极软到极硬的金属材料,它弥补了布氏法的不是,较布氏法简便,可直接从硬度机的表盘读出硬度值。但是,由于其压痕小,故硬度值不如布氏法准确。           C、维氏硬度(HV)       维氏硬度试验也是一种压痕试验方法,是将一个相对面夹角为1360的正四棱锥体金刚石压头以选定的试验力(F)压入试验表面,经规定保持时间后卸除试验力,测量压痕两对角线长度。       维氏硬度值是试验力除以压痕表面积所得之商,其计算公式为:       式中:HV--维氏硬度符号,N/mm2(MPa);       F--试验力,N;       d--压痕两对角线的算术平均值,mm。       维氏硬度采用的试验力F为5(49.03)、10(98.07)、20(196.1)、30(294.2)、50(490.3)、100(980.7)Kgf(N)等六级,可测硬度值范围为5~1000HV。       表示方法举例:640HV30/20表示用30Hgf(294.2N)试验力保持20S(秒)测定的维氏硬度值为640N/mm2(MPa)。       维氏硬度法可用于测定很薄的金属材料和表面层硬度。它具有布氏、洛氏法的主要优点,而克服了它们的基本缺点,但不如洛氏法简便。维氏法在钢管标准中很少用。       ⑥冲击韧性指标       冲击韧性是反映金属才来哦对外来冲击负荷的抵抗能力,一般由冲击韧性值(ak)和冲击功(Ak)表示,其单位分别为J/cm2和J(焦耳)。       冲击韧性或冲击功试验(简称"冲击试验"),因试验温度不同而分为常温、低温和高温冲击试验三种;若按试样缺口形状又可分为"V"形缺口和"U"形缺口冲击试验两种。       冲击试验:用一定尺寸和形状(10×10×55mm)的试样(长度方向的中间处有"U"型或"V"型缺口,缺口深度2mm)在规定试验机上受冲击负荷打击下自缺口处折断的实验。       A、冲击吸收功Akv(u)--具有一定尺寸和形状的金属式样,在冲击负荷作用下折断时所吸收的功。单位为焦耳(J)或Kgf . m。       B、冲击韧性值akv(u)--冲击吸收功除以试样缺口处底部横截面积所得的商。单位为焦耳/厘米2(J/cm2)或公斤力 . 米/厘米2(Kgf . m/cm2)。计算公式为:       式中:Akv(u)--试样折断时所吸收的功,Kgf . m(J);       S --试样缺口处底部横截面面积,cm2。     常温冲击试验温度为20±50C;低温冲击试验温度范围为<15~-1920C;高温冲击试验温度范围为35~10000C。       低温冲击试验所用冷却介质一般为无毒、安全、不腐蚀金属和在试验温度下不凝固的液体或气体。如无水乙醇(酒精)、固态二氧化碳(干冰)或液氮雾化气(液氮)等。

热镀锌钢材

2017-06-06 17:50:06

热镀锌钢材包括热镀锌钢管、热镀锌板、热镀锌带钢、热镀锌角钢、热镀锌扁钢等等,这些都是热镀锌钢材产品,之所以对这些产品热镀锌,是为了达到防腐的目的。钢材(Steel):是钢锭、钢坯或钢材通过压力加工制成所需要的各种形状、尺寸和性能的材料。钢材是国家建设和实现四化必不可少的重要物资,应用广泛、品种繁多,根据断面形状的不同、钢材一般分为型材、板材、管材和 金属 制品四大类、为了便于组织钢材的生产、订货供应和搞好经营管理工作,又分为重轨、轻轨、大型型钢、中型型钢、小型型钢、钢材冷弯型钢,优质型钢、线材、中厚钢板、薄钢板、电工用硅钢片、带钢、无缝钢管钢材、焊接钢管、 金属 制品等品种。钢是含碳量在0.04%-2.3%之间的铁碳合金。为了保证其韧性和塑性,含碳量一般不超过1.7%。钢的主要元素除铁、碳外,还有硅、锰、硫、磷等。热镀锌也叫热浸锌和热浸镀锌,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。热镀锌生产工艺流程主要包括:原板准备&rarr;镀前处理&rarr;热浸镀&rarr;镀后处理&rarr;成品检验等。现在钢材的表面镀锌主要采用的方法是热镀锌。热镀锌是由较古老的热镀方法发展而来,自从1836年法国把热镀锌应用于工业以来,已经有170年的历史了。然而近30年来,伴随冷轧带钢的飞速发展,热镀锌工业得到了大规模发展。热镀锌钢材在镀锌钢材 市场 上需求量大,相反电镀锌钢材使用的少,只有部分小企业还在制造电镀锌产品,电镀锌已被禁止。
