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 、

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。

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

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

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。

热轧板规格

2019-03-18 10:05:23

采用SAE1006,生产设施配套热轧板表面处理酸洗线、光亮罩式退火炉、四棍可逆冷轧,并配有板面精密平整机组,消除应力平面拉矫机,高精密分条机组。 齐全可轧制厚度为0.08mm~1.5mm厚薄公差控制在±0.02mm以内,宽度由180mm~630mm冷轧卷板。 具有延伸率高、表面光滑达到镜面效果、厚薄度标准、板形平直、耐生锈等特点,适用于各种五金冲压、拉伸性能良好。如LED支架、转定子、灯饰、风扇、摩托车油箱、钢管、家用电器及外壳等各类五金产品。 热卷规格为:2.75*1500*C、3.0*1500*C、3.25*1500*C、3.5*1500*C、3.75*1500*C、4.25*1500*C、4.5*1500*C、4.75*1500*C、5.25*1500*C、5.5*1500*C、5.75*1500*C、6.5*1500*C、7.25*1500C、7.5*1500*C、7.75*1500*C、9.25*1500*C、9.5*1500*C、9.75*1500*C、11.25*1500*C、11.5*1500*C、11.75*1500*C... 热轧板规格板材:(1)中厚板 :钢板是一种宽厚比和表面积都很大的扁平钢材。按厚度为为薄钢板(厚度 4毫米)在实际工作中 ,常将厚度 20-60毫米的钢板称为厚板,厚度>60毫米的钢板称为特厚板,统称为中厚钢板。宽度比较小,长度很长的钢板,称为钢带,列为一个独立的品种。钢板有很大的覆盖和包容能力,可用作屋面板、苫盖材料以及制造容器、储油罐、包装箱、火车车箱、汽车外壳、工业炉的壳体等:可按使用要求进行剪裁与组合,制成各种结构件和机械零件,还可制成焊接型钢,进一步扩大钢板的使用范围;可以进行弯曲和冲压成型,制成锅炉、容器、冲制汽车外壳、民用器皿、器具、还可用作焊接钢管、冷弯型钢的坯料。钢板成张或成卷供应。成张钢板的规格以厚度*宽度*长度的毫米数表示。熟悉板、带材的规格,在宽度和长度上充分利用,对提高材料利用率,减少不适当的边角余料、降低工时及产品成本,有十分重要的意义。 普中板、低合金板、容器板 锅炉板 桥梁板、船板。注:这几种板材均出自中厚板轧机,只是由于炼钢所加入材料的不同而区分开来,其外形、厚度、规格基本设置基本相同,一般厚度为6-120mm,其中6 mm、8 mm、10 mm、12mm中厚板价格依次降低,6mm中厚板价格在其中属最贵档次;14-30mm为常用规格,价格处于同一水平;32-49mm属于厚板系列,价格处于同一水平,比常用规格板价格略贵;50-120mm属于超厚板系列,50-90mm板价格处于同一水平,90mm以上规格板价格随着厚度的增加将提高。中厚板代表规格为20mm。 (2)板卷:a、热轧板卷:热轧,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钢带。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。简单点儿来说,一块钢坯在加热后(就是电视里那种烧的红红的发烫的钢块)精过几道轧制,再切边,矫正成为钢板,这种叫热轧。 热轧板卷(以平板形式或者卷板形式存在)一般厚度在2.0-13.5mm之间,其中2.0-3.0mm热卷价格从薄到厚逐渐降低;大部分钢厂3.1mm-13.5mm价格基本相当,部分厂家、市场3.1-4.0mm以及9.5mm-13.5mm热板卷价格可能高于4.0mm-9.5mm板的价格,热板卷代表规格为5.5mm厚产品,正常情况下平板的价格略高于卷板的价格。 b、冷轧板卷: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。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。

铅黄铜热轧开裂的原因分析

2018-12-18 11:17:20

一、前言:铅黄铜板做为特殊的Cu-Zn-Pb三元组合黄铜加工材,由于其较一般普通黄铜易切削、易机械加工、且耐腐蚀性,耐磨性能较高,因此,用途较为广泛。主要应用于:钟表制造、鞋业制造,机械零件制造及汽车零配件制造等行业。但由于铅黄铜的特殊组元,其热加工性能较差,经常遇到的问题是热轧过程中,板坯表面时常会出现开裂现象。严重地影响了铅黄铜板的生产,本文根据我们多年的生产实践,对铅黄铜热轧开裂原因做一分析,供同行参考。二、经常使用的铅黄铜板的牌号及成份2.1、生产中,经常遇到的铅黄铜板有以下几个牌号:1、Hpb59-1(GB) 2、C37700(AsTM)3、C3771(JIS)2.2、铅黄铜主要生产牌号的化学成份三、热轧铅黄铜工艺(板式法生产)3.1 锭坯尺寸:60(厚)×360(宽)×900(长)3.2 热轧成品尺寸:6(厚)×600(宽)×5400(长)3.3 锭坯加热及轧制设备:3.3.1 锭坯加热设备:步进式柴油加热炉。1.5m(高)×3m(宽)×25m(长)3.3.2热轧设备:Ф450×860二辊非可逆式热轧机3.4热轧工艺四、生产中常见的铅黄铜轧制裂纹类型4.1 生产中常见的热轧板坯裂纹的类型实际生产中,铅黄铜热轧裂纹主要有以下两种:1、板坯边部裂纹。2、板坯碎裂。4.2热轧板坯裂纹图示:五、铅黄铜阀体开裂原因分析HPb59-1铅黄铜热锻产品在后期加工过程中出现大量开裂现象,采用金相及电子探针分析方法对HPb59-1铅黄铜阀体开裂原因进行分析。结果发现:铅黄铜阀体材质铅含量较高,显微组织分布不均匀,晶粒粗大;断口表面除含有大量富Pb的腐蚀产物外,还存在明显的高Pb和S元素的富集区.表明,热锻造过程中操作不当,退火不充分及腐蚀介质的存在,从而造成阀体的应力腐蚀开裂.。

铸造工艺及要求加热热轧

2019-05-29 19:34:52

铸造技术及要求 在半连续加工过程中,应避免铸造过程中的二次吸气。脱氧铜在浇铸过程中,如不进行维护,仍可吸收0.01%的氧。因而,应选用埋管式浇铸,液面选用优质烟灰或经脱水处理的发生炉煤气进行铸造维护,操作中留意看稳液面。浇铸前有必要对引锭托座进行烘烤。一般选用短结晶器,铸造速度和水压依据锭坯规格确认,以确保锭坯表面无冷隔、裂纹为宜。铸造温度应控制在1140~1160℃。热轧前应对铜铸锭表面易发生的冷隔、裂纹等进行修补和铣面,确保铸锭表面润滑、平坦,内部无搀杂、气孔等缺点。当紫铜铸锭表面缺点少时,一般不宜进行铣面。  加热及热轧 无氧铜TU1和含磷量小于0.001%的T2铜铸锭的高温功能。无氧铜TU1和紫铜T2铸锭均在200~300℃的中温区内出现脆性。研讨证明,这是由杂质氢或磷引起的。因为氢和磷都是表面活性元素,易吸附在铜的晶界上引起中温脆性。  因为铜在高温下的氧化速度随温度的升高而明显加速,在高温过程中,氧会经过渗透到铜的表面层内。无氧铜在空气中的渗透到铜的表面层内。无氧铜在空气中的渗氧深度与退火温度、时刻的联系。为了进步加工功率,削减氧化丢失,确保带坯的正常轧制,在设备情况答应的情况下,变压器用铸锭一般选用“高温、快速、均匀、中性或微复原性气氛”条件进行加热。铸锭一般选用步进式加热炉、出炉料温应控制在850~920℃应确保铸锭温度均匀、烧透,避免过热及过烧。热轧开坯温度高于820℃,终轧温度不低于600℃。

  铜资源的短缺与需求的增长,国际铜价的高涨,使人们对铜加工业的发展有了更深刻的认识:铜材加工将由普通加工业进入精密加工时代,那种以高投入,传统生产技术和装备新建和改造现有企业的方式应重新加以审势,而以实用的创新技术建设高效、专业化的铜加工企业已经显现出了光明的前景。我国铜加工技术创新的方向是:  1、发展短流程生产工艺技术,紧密围绕着节能,节省 金属 消耗、环境保护方向开展技术创新,在 金属 压力加工允许的情况下,尽量压缩热加工工序;    2、发展适合我国资源国情和 市场 需求的铜及合金产品,围绕发展精密铜材品种开展技术创新;  3、近一步发展我国潜流式生产技术,不断扩大在铜加工生产中的应用范围,其重点是高精带材和精密管材生产;  4、研制、开发、生产高效、环保、节能、自动化、连续化、专业化、低成本的铜加工技术装备和生产线;  5、加强铜加工分析测试和在线检查等技术创新;研制、开发、生产先进的、实用的。低成本的分析检测装备和仪器,扭转铜加工先进分析检测装备依靠国外的被动局面;  6、着力培养具有创新意识的管理和技术专业人材。  由于我国经济持续快速增长,带动了电气、电子、汽车、电力等铜板带材主要使用 行业 的高速增长。同时,中国日益成为世界制造中心,带动国际铜加工业,以及大量用铜 行业 向中国转移。在国内 市场 直接消费和国际 市场 间接消费的双重驱动下,国内铜板带材的 市场 需求持续快速增长,年平均增长率高达36.1%。据此,结合国内主要铜消费 行业 的发展前景,预计到2010 年国内铜板带材的 市场 需求为160 万吨左右,发展空间广阔。  铜材在电力、汽车、建筑、交通运输等 产业 中均扮演重要角色。“制造业的兴衰与生活质量的变化是决定铜需求量的主要原因。”海亮董秘汪鸣说。数据显示,西方发达国家GDP增长率超过2.4%时,每增长1%,铜的消费量增长3.24%。机构 预测 ,到2010年,中国人均铜消费量将达到4000克。中国的铜产品 产量 约占世界总 产量 的三分之一,是世界上最大的铜产品生产国,同时,由于经济的发展迅速拉动了铜产品消费 市场 的增长,中国也已成为世界上最大的铜产品消费国。   在中国,家电 行业 用铜管的需求是铜加工企业最大的 市场 机会,其中空调、压缩机对铜产品的需求极大。而世界铜管的总消费量中,也有超过一半是空调用管。   在建筑用铜管 市场 ,美、英等国已形成使用铜管的习惯,由于铜价的上升,选择替代品的消费者略有增加,但对于整体上升的趋势并不会造成太大影响,机构 预测 ,今后仍会维持在年均百万吨以上的需求。这为性价比高的中国铜管产品提供了良机。   此外,在海水淡化、船舶工业和电力工业等领域,未来几年的铜管消费量也将持续攀升,而这些领域所采用的铜管对中国铜材加工企业来说,也将是前所未有的商机,借此,中国企业将实现高成长,甚至替代国际厂商。
