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)。

铝合金板片的生产工艺

2019-01-10 09:44:13

一种工艺用来生产有着高屈服强度和合适延展性的铝合金板材,特别是用于制造汽车的面板。这个工艺包括将没有经过热处理的铝合金铸造成一个铸坯,然后所述的铸坯经过一系列的轧制得到较终规格的板材,更好的选择是随后的热处理退后产生再结晶。轧制步骤包括热轧和中温轧制铸坯以得到中间厚度的中间制品,然后冷却中间制品,接着在室温到340摄氏度的范围内中温轧制以及冷轧中间制品得到较终的规格的板材。这一系列的轧制过程是连续进行的没有中间品的圈绕和对中间板材的完全退火。该发明还涉及合金制品的薄板。    本发明涉及生产一种生产铝板材的工艺流程。特别是,本发明涉及通过轧制法从不经热处理合金中生产处适合成形的板材。例如,在制造汽车面板方面的5000系列铝合金。    5000系列铝合金(即镁作为主要的合金元素)通常用于汽车的面板(护板、门板、罩等等),对于这样的应用,为合金板片提供高屈服点和高延展性时所想要达到的。合适规格和屈服强度的铝合金片可由连续浇铸之后的轧制得到。在传统的连铸过程中,从铸造中得到的金属经过热轧和温制,然后盘绕(在温度大约300摄氏度)接着被送往另一轧机,在不超过160摄氏度的温度进行较后的冷轧。    为了精炼,在这里所要提到的一点是通常所指的“热轧”是在温度高于合金的再结晶温度时实施的。以便合金在轧辊型缝之间或在滚动以后的线圈中自己退火再结晶。所述的“冷轧”通常意味着具有大量加工硬化率的工作轧辊以便在轧制期间或之后的合金既没有重结晶也不会发生回复。“中温轧制”在二者之间执行,以便没有重结晶作用但是屈服强度由于恢复过程而大幅度减少。对于铝合金,热轧温度超过350摄氏度,冷轧温度小于150摄氏度,中温轧制在150和350摄氏度之间实施。    不幸地是,上述的常规方法的中间卷绕是笨重和昂贵的,储运需要获得一产品,其具有一个合适的微晶结构,以生产预期的屈服强度。    在美国专利号5,514,228中,在1996年5月7日公开一个同轴的连铸过程,其中板片没有经过中间圈绕而轧成较后所需的规格。不过,在较终的轧制之前还需要进一步的固溶处理,以便在较后的卷绕之前板片进行连续地完全被退火。然而,5000系列合金经固溶处理后不会被强化。    本发明的一个目的是以方便和经济的方式生产不经热处理的铝合金板片以便适用于汽车版面的制造。    本发明的另一个目的是,提供一种工艺以连续的步骤而不经过中间的二级轧制生产5000系列的铝合金板片,以得到高屈服点的铝合金产品。    本发明的一方面,提供生产铝合金板片的一种工艺,其中包括:铸造不经热处理的铝合金以形成一个扁钢锭,然后扁钢锭经过一系列的轧制步骤,以生产较后规格的产品。轧制步骤包括:热轧和中温轧制板坯,形成中级规格中间板片,冷却间板片;然后在室温到340摄氏度的温度范围内对中间板片进行中温轧制和冷轧;一系列连续的轧制步没有中间片的卷绕或完全退火。    上述流程在所谓的H2回火中一种合金。进一步的退火再结晶生产处适合于汽车所用的板片。    本发明的另一方面,提供一种铝合金板片由不经热处理的铝合金制成,这一个过程包括:铸造不经热处理的铝合金,以形成扁钢锭;所述扁钢锭经过一系列的轧制,以生产较后规格的制品;轧制步骤包括:热轧和中温轧制板坯,形成中级规格的中间片,冷却中间片,然后在室温到340摄氏度的温度范围内对中间板片进行中温轧制和冷轧;一系列连续的轧制步没有中间片的卷绕或完全退火。    如上所述,本发明需要热轧和中温轧制然后不经中级圈绕或完全退后进行中温轧制和冷轧。当连续轧制扁钢锭的时候,热板坯向空气和轧辊失去热,以便热轧在中温轧制中结束(即在结晶温度以下)。    这就是通过热轧和中温轧制的方法。在热轧期间,金属完全再结晶以释放在铸造期间产生的任何应变能。这期间的温度取决于同时发生的冷加工的发生量,以及合金的组成。在中温轧制期间,应变能量由于逐渐的轧制而建立,这就是金属所谓的“恢复”。如同重结晶作用一样,出去温度影响外恢复程度取决于冷加工的量和合金的组成。重结晶和恢复之间的重要的区别是,即重结晶作用导致内部张力迅速的减少并在热轧期间发生,然而恢复是中温轧制和冷轧的整个周期中发生,而且内部张力是平稳的减少的,但是大部分压力在“暖和的”轧制期间被释放。    本发明的过程对任何不经热处理的铝合金有益,这些铝合金较终的处理方式是完全退火状态。不过,加强晶粒度在汽车应用方面的5000系列合金中是较重要的。过程可用于所有的5000系列合金在完全退火状态中被运送,但是对AA5754合金尤其有用,此合金含有有限量的Mg,为了避免应力腐蚀裂纹,对此合金来说,加强晶粒度是特别重要的。Mg含量更高的例如AA5182合金,对应力腐蚀裂纹敏感,但它们有更高的强度。对于这样的合金的当然是有益的,但是不那么明显。    本发明的工艺,至少在它的优选的形式中,提供一种制作汽车车身结构的5000系列的铝片,其在一台连铸机上经过连续的轧制得到良好的机械性能。    本发明的一个优点是,虽然自身退火不会生产优选的微观结构和性质,但是在较低温度的轧制以后的重结晶以及接着的退火,确实生产预期的细粒尺寸、高强度和有利的晶体织构。    1.生产铝合金板片的一种工艺,包括:铸造不经热处理的铝合金以形成一个扁钢锭,然后扁钢锭经过一系列的轧制步骤,以生产较后规格的产品。轧制步骤包括:热轧和中温轧制板坯,形成中级规格中间板片,冷却间板片;然后在室温到340摄氏度的温度范围内对中间板片进行中温轧制和冷轧;一系列连续的轧制步没有中间片的卷绕或完全退火。

冷轧镀锌

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。

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。

镀锌网片

2017-06-06 17:50:06

网片根据加工工艺的不同,分成电焊网片、镀锌网片、不锈钢网片、点焊网片等等。其中镀锌网片,是指网片在成型之后,所进行的防锈处理,在网片上镀上一层锌,提高网片的耐锈蚀性。镀锌电焊网片系选用优质铁丝,通过精密的自动化机械焊接制成,电焊网片成型后进行镀锌(电镀或热镀)。网片是由网线编织成的一定尺寸网目结构的片状编织物。主要用于煤矿护顶、隧道、桥梁建设、路基网筋、建筑工地。制作网片的材质可以是低碳钢丝、电镀锌丝、电镀锌改拔丝。 可以分为:不锈钢网片、黑铁丝网片、镀锌铁丝网片、涂塑网片、带框网片、镀铜电焊网片。网片之所以在许多地方可以派上用处,是因为它的优点多多。焊接牢固,网孔均匀,网面平整,耐腐蚀、强度大、防护能力强。镀锌网片在镀锌工艺之后,还可以涂上颜色,不仅增强了防蚀性能,还美观,我们称之为“装饰网片”。这种类型的镀锌网片被广泛运用于展览会的布置、商场的样品架。镀锌网片的产品规格

      钨铜合金片是钨铜合金的一种材料类型,综合了 金属 钨和铜的优点,其中钨熔点高(钨熔点为3410℃,铁的熔点1534℃),密度大(钨密度为19.34g/cm3,铁的密度为7.8 g/cm3) ;铜导电导热性能优越,其微观组织均匀、耐高温、强度高、耐电弧烧蚀、密度大;导电、导热性能适中。     常用合金的含铜量为10%~50%。合金用粉末冶金方法制取,具有很好的导电导热性,较好的高温强度和一定的塑性。在很高的温度下,如3000℃以上,合金中的铜被液化蒸发,大量吸收热量,降低材料表面温度。所以这类材料也称为 金属 发汗材料。钨铜合金有较广泛的用途,主要是用来制造抗电弧烧蚀的高压电器开关的触头和火箭喷管喉衬、尾舵等高温构件,也用作电加工的电极、高温模具以及其他要求导电导热性能和高温使用的场合。      钨铜合金片具有高强度/高比重/耐高温/耐电弧烧蚀/导电电热性能好/加工性能好,采用高品质钨粉及无氧铜粉,应用等静压成型(高温烧结-渗铜),保证产品纯度及准确配比,组织细密,性能优异. 断弧性能好,导电性好,导热性好,热膨胀小。广泛应用于军用耐高温材料、高压开关用电工合金、电加工电极、微电子材料,做为零部件和元器件广泛应用于航天、航空、电子、电力、冶金、机械、体育器材等 行业 。    

纯铜散热片

2017-06-06 17:50:04

相较于其他材料的散热片,纯铜散热片的优点尤为突出。散热片是一种给电器中的易发热电子元件散热的装置,多由铝合金,黄铜或青铜做成板状,片状,多片状等,如电脑中CPU中央处理器要使用相当大的散热片,电视机中电源管,行管,功放器中的功放管都要使用散热片。一般散热片在使用中要在电子元件与散热片接触面涂上一层导热硅脂,使元器件发出的热量更有效的传导到散热片上,在经散热片散发到周围空气中去。就散热片材质来说,每种材料其导热性能是不同的,按导热性能从高到低排列,分别是银,铜,铝,钢。不过如果用银来作散热片会太昂贵,故最好的方案为采用铜质。虽然铝便宜  散热片得多,但显然导热性就不如铜好(大约只有铜的50%左右)。目前常用的散热片材质是铜和铝合金,二者各有其优缺点。铜的导热性好,但 价格 较贵,加工难度较高,重量过大(很多纯铜散热器都超过了CPU对重量的限制),热容量较小,而且容易氧化。而纯铝太软,不能直接使用,都是使用的铝合金才能提供足够的硬度,铝合金的优点是 价格 低廉,重量轻,但导热性比铜就要差很多。有些散热器就各取所长,在铝合金散热器底座上嵌入一片铜板。钢制散热器:外形美观,但怕氧化,要采取内防腐处理,停水时一定要充水密封,防止空气进入。并且其对小区的供暖系统有一定要求,需专业人员上门查看。铝制散热器:不受小区采暖系统的限制,散热性较好,节能;若发现室内温度不够,还可以在采暖季之后加装暖气片。但铝材料怕碱水腐蚀,进行内防腐处理可提高使用寿命。铜铝制散热器:承压能力高,散热效果好,防腐效果好,采暖季过后无须满水保养,没有碱化和氧化之虞,比较适合北方的水质及复杂的供暖系统,但造型较单一。纯铜散热片由于抗氧化性能差,所以往往采用铜铝合金作为散热片的材料。

铝板片的生产工艺

2019-01-10 09:44:13

一种工艺用来生产有着高屈服强度和合适延展性的铝合金板材,特别是用于制造汽车的面板。这个工艺包括将没有经过热处理的铝合金铸造成一个铸坯,然后所述的铸坯经过一系列的轧制得到较终规格的板材,更好的选择是随后的热处理退后产生再结晶。轧制步骤包括热轧和中温轧制铸坯以得到中间厚度的中间制品,然后冷却中间制品,接着在室温到340摄氏度的范围内中温轧制以及冷轧中间制品得到较终的规格的板材。这一系列的轧制过程是连续进行的没有中间品的圈绕和对中间板材的完全退火。该发明还涉及合金制品的薄板。    本发明涉及生产一种生产铝板材的工艺流程。特别是,本发明涉及通过轧制法从不经热处理合金中生产处适合成形的板材。例如,在制造汽车面板方面的5000系列铝合金。    5000系列铝合金(即镁作为主要的合金元素)通常用于汽车的面板(护板、门板、罩等等),对于这样的应用,为合金板片提供高屈服点和高延展性时所想要达到的。合适规格和屈服强度的铝合金片可由连续浇铸之后的轧制得到。在传统的连铸过程中,从铸造中得到的金属经过热轧和温制,然后盘绕(在温度大约300摄氏度)接着被送往另一轧机,在不超过160摄氏度的温度进行较后的冷轧。    为了精炼,在这里所要提到的一点是通常所指的“热轧”是在温度高于合金的再结晶温度时实施的。以便合金在轧辊型缝之间或在滚动以后的线圈中自己退火再结晶。所述的“冷轧”通常意味着具有大量加工硬化率的工作轧辊以便在轧制期间或之后的合金既没有重结晶也不会发生回复。“中温轧制”在二者之间执行,以便没有重结晶作用但是屈服强度由于恢复过程而大幅度减少。对于铝合金,热轧温度超过350摄氏度,冷轧温度小于150摄氏度,中温轧制在150和350摄氏度之间实施。    不幸地是,上述的常规方法的中间卷绕是笨重和昂贵的,储运需要获得一产品,其具有一个合适的微晶结构,以生产预期的屈服强度。    在美国专利号5,514,228中,在1996年5月7日公开一个同轴的连铸过程,其中板片没有经过中间圈绕而轧成较后所需的规格。不过,在较终的轧制之前还需要进一步的固溶处理,以便在较后的卷绕之前板片进行连续地完全被退火。然而,5000系列合金经固溶处理后不会被强化。    本发明的一个目的是以方便和经济的方式生产不经热处理的铝合金板片以便适用于汽车版面的制造。    本发明的另一个目的是,提供一种工艺以连续的步骤而不经过中间的二级轧制生产5000系列的铝合金板片,以得到高屈服点的铝合金产品。    本发明的一方面,提供生产铝合金板片的一种工艺,其中包括:铸造不经热处理的铝合金以形成一个扁钢锭,然后扁钢锭经过一系列的轧制步骤,以生产较后规格的产品。轧制步骤包括:热轧和中温轧制板坯,形成中级规格中间板片,冷却间板片;然后在室温到340摄氏度的温度范围内对中间板片进行中温轧制和冷轧;一系列连续的轧制步没有中间片的卷绕或完全退火。    上述流程在所谓的H2回火中一种合金。进一步的退火再结晶生产处适合于汽车所用的板片。    本发明的另一方面,提供一种铝合金板片由不经热处理的铝合金制成,这一个过程包括:铸造不经热处理的铝合金,以形成扁钢锭;所述扁钢锭经过一系列的轧制,以生产较后规格的制品;轧制步骤包括:热轧和中温轧制板坯,形成中级规格的中间片,冷却中间片,然后在室温到340摄氏度的温度范围内对中间板片进行中温轧制和冷轧;一系列连续的轧制步没有中间片的卷绕或完全退火。    如上所述,本发明需要热轧和中温轧制然后不经中级圈绕或完全退后进行中温轧制和冷轧。当连续轧制扁钢锭的时候,热板坯向空气和轧辊失去热,以便热轧在中温轧制中结束(即在结晶温度以下)。    这就是通过热轧和中温轧制的方法。在热轧期间,金属完全再结晶以释放在铸造期间产生的任何应变能。这期间的温度取决于同时发生的冷加工的发生量,以及合金的组成。在中温轧制期间,应变能量由于逐渐的轧制而建立,这就是金属所谓的“恢复”。如同重结晶作用一样,出去温度影响外恢复程度取决于冷加工的量和合金的组成。重结晶和恢复之间的重要的区别是,即重结晶作用导致内部张力迅速的减少并在热轧期间发生,然而恢复是中温轧制和冷轧的整个周期中发生,而且内部张力是平稳的减少的,但是大部分压力在“暖和的”轧制期间被释放。    本发明的过程对任何不经热处理的铝合金有益,这些铝合金较终的处理方式是完全退火状态。不过,加强晶粒度在汽车应用方面的5000系列合金中是较重要的。过程可用于所有的5000系列合金在完全退火状态中被运送,但是对AA5754合金尤其有用,此合金含有有限量的Mg,为了避免应力腐蚀裂纹,对此合金来说,加强晶粒度是特别重要的。Mg含量更高的例如AA5182合金,对应力腐蚀裂纹敏感,但它们有更高的强度。对于这样的合金的当然是有益的,但是不那么明显。    本发明的工艺,至少在它的优选的形式中,提供一种制作汽车车身结构的5000系列的铝片,其在一台连铸机上经过连续的轧制得到良好的机械性能。    本发明的一个优点是,虽然自身退火不会生产优选的微观结构和性质,但是在较低温度的轧制以后的重结晶以及接着的退火,确实生产预期的细粒尺寸、高强度和有利的晶体织构。    1.生产铝合金板片的一种工艺,包括:铸造不经热处理的铝合金以形成一个扁钢锭,然后扁钢锭经过一系列的轧制步骤,以生产较后规格的产品。轧制步骤包括:热轧和中温轧制板坯,形成中级规格中间板片,冷却间板片;然后在室温到340摄氏度的温度范围内对中间板片进行中温轧制和冷轧;一系列连续的轧制步没有中间片的卷绕或完全退火。
