Description

冷轧高强度热镀锌钢板及制备方法
技术领域
本申请属于冶金技术领域,特别涉及一种冷轧高强度热镀锌钢板及制备方法。
背景技术
冷轧热镀锌钢板具有耐腐蚀性强、表面质量好等优点。高强度的热镀锌钢板可以提高结构件的强度;另一方面也可在保证结构强度的前提下,降低钢板的厚度从而降低用户使用成本。因此建筑行业对高强度结构用镀锌钢板的需求逐步增加,用于轻钢结构、户外广告箱等制造。这些结构通常形状简单,对钢板的成型性能要求低。
提高钢板强度有多种方法。通常的做法是在钢中添加Nb、V、Ti等微合金元素,利用固溶强化、析出强化、细晶强化等机制提高强度,但是这种方法添加的合金元素显著增加生产成本。在汽车行业使用的高强度钢板通常采用相变强化技术,依靠退火后的快速冷却进行相变,获得铁素体+马氏体或铁素体+贝氏体等双相组织,该技术对产线设备有非常高的要求。
热轧后的钢板在冷轧轧制过程中,晶粒被压扁拉长成细条状的纤维组织,位错大量增殖,产生明显的加工硬化,普通低碳钢在冷轧轧制后强度可以达到700MPa以上。通过降低冷轧后钢板退火时的温度,控制显微组织的回复和再结晶程度,就可以充分利用加工硬化产生的强度提升,低成本生产高强度镀锌钢板。
发明内容
本发明的目的在于提供一种冷轧高强度热镀锌钢板及制备方法,钢板采用低碳低锰成分设计,退火及热镀锌后钢板屈服强度达到500-650MPa。
为实现上述目的,本发明提供如下技术方案:
本申请实施例公开了一种冷轧高强度热镀锌钢板,其化学成分按重量百分比为:C:0.12-0.16%、Mn:0.60-0.90%、Si≤0.05%、P≤0.02%、S≤0.01%、Als:0.02-0.05%,其余为Fe和其他不可避免的杂质。
优选的,在上述冷轧高强度热镀锌钢板中,该钢板屈服强度为500-650MPa,抗拉强度为520-680MPa,延伸率为3-15%。
相应的,还公开了一种冷轧高强度热镀锌钢板的制备方法,依次包括如下步骤:
1)热轧轧制工序,连铸板坯加热温度为1180-1250℃,终轧温度为820-880℃,卷取温度为600-660℃;
2)酸洗冷连轧工序,冷轧压下率55-75%;
3)退火及热镀锌工序;
4)平整工序,平整压下率0.8-2.0%。
优选的,在上述的冷轧高强度热镀锌钢板的制备方法中,步骤3)退火及热镀锌工序中,采用美钢联法实施连续退火及热镀锌,产线配备立式退火炉,钢板进入退火炉前进行化学脱脂和电解脱脂,提高表面洁净度。
优选的,在上述的冷轧高强度热镀锌钢板的制备方法中,步骤3)退火及热镀锌工序中,进入锌锅前的均热退火温度为560-600℃,均热时间为35-50s;进入锌锅时钢板温度为480-500℃;锌锅温度为450-470℃,锌液中Al含量为0.17-0.25%、Fe含量<0.03%。
优选的,在上述的冷轧高强度热镀锌钢板的制备方法中,步骤3)退火及热镀锌工序中,获得的单面锌层重量为40-150g/m2
优选的,在上述的冷轧高强度热镀锌钢板的制备方法中,步骤4)平整工序中,采用直径400-500mm的小辊径平整辊。
与现有技术相比,本发明有益效果在于:
(1)采用低碳低锰成分设计,未添加Nb、V、Ti等昂贵合金元素;利用冷轧轧制时产生的加工硬化在退火前获得高强度,此后在较低的温度下退火,通过退火温度来调节钢板强度,该成分设计结合低温退火工艺,生产成本低;
(2)退火过程采用高带速,在560-600℃退火温度下,钢板在均热退火段的通过时间为35-50s,高带速有利于减少晶粒回复和再结晶的程度,同时增加生产效率;
(3)采用立式连续退火炉进行热处理,与卧式退火炉相比,生产效率高,表面质量好;
(4)采用小辊径平整辊有利于减少平整轧制力,通过平整压下量的控制,可以进一步调整带钢强度。
通过本发明成分和制备方法获得的高强度镀锌钢板,其典型金相组织为纤维状轧硬组织+少量再结晶铁素体+少量碳化物,屈服强度为500-650MPa,抗拉强度为520-680MPa,延伸率为3~15%,钢板生产成本低,表面质量优良,耐腐蚀性能好。
