CN108504947A 一种二次冷轧镀锡板及其生产方法 无效 - 驳回

一种二次冷轧镀锡板及其生产方法
摘要：
本发明公开了一种二次冷轧镀锡板及其生产方法，属于轧钢技术领域。按照质量百分比，所述二次冷轧镀锡板的化学成分为：C：0.06％～0.09％，Si≤0.02％，Mn：0.30％～0.50％，P≤0.015％，S≤0.012％，Als：0.005％～0.02％，N：0.0200％～0.0250％，余量为Fe及不可避免的杂质。其生产方法包括连铸、热轧、酸洗、冷轧、连续退火、二次冷轧及镀锡过程。本发明通过成分设计和工艺优化，可生产低成本、高强度、高塑性的镀锡板。
摘要（英）：

The invention discloses a twice cold reduced tin plate and a manufacture method thereof, belonging to the technical field of steel rolling. Chemical components of the twice cold reduced tint plate comprise 0.06%-0.09% of C, less than or equal to 0.02% of Si, 0.30%-0.50% of Mn, less than or equal to 0.015% of P, less than or equal to 0.012% of S, 0.005%-0.02% of Als, 0.0200%-0.0250% of N, and the balance of Fe and inevitable impurities. The manufacture method comprises the steps of continuous casting, hot rolling, acid pickling, cold rolling, continuous annealing, secondary cold rolling, and tin plating. Due to component proportioning and process optimization, the prepared tin plate is low-cost but has high strength and high plasticity.
