一、前言随着国内汽车制造业的迅速发展,汽车厂对冲压用冷轧钢板的需求也日益增加。武钢冷轧厂是国内生产汽车板的主要厂家,但由于现有08A1钢成分要求严格,工艺条件复杂,致使供应受到一定影响。为了满足汽车制造业的需求,我公司研制了汽车冲压用Q_1A1钢,其使用效果达到GB710—65 08A1钢的水平。本文就83、84年试制研究工
I. Introduction With the rapid development of the domestic automobile manufacturing industry, the demand for cold rolled steel sheet for stamping is also increasing. Cold-rolled steel plant in WISCO is a major manufacturer of automobile plates in China. However, due to the strict requirements of existing 08A1 steel compositions and complicated process conditions, the supply is affected to a certain extent. In order to meet the needs of the automotive manufacturing industry, our company developed a car stamping Q_1A1 steel, its use to achieve the level of GB710-65 08A1 steel. In this paper, 83, 84 trial research workers
