摘　　要：随着汽车轻量化技术推进,冷轧双相高强钢在汽车领域的使用范围及占比逐年增加。但由于该钢种加工工艺决定了钢中的碳、锰及硅元素含量较高,在实际生产过程中焊接不良、酸洗效率偏低及轧制不稳定等方面对此类钢种的高效生产影响较大。通过对该类钢种从焊接工艺对焊接质量的影响,原料条件对酸洗效率的影响以及稳定轧制影响因素的分析及改善,在保证产品质量的前提下实现生产效率提升30%。With the advancement of HSS technology in the automotive industry,the use and proportion of DP high-strength steel in automobiles have been increasing year by year.However,due to the high content of C,Mn,and Si elements in DP steel determined by its processing technology,it has a significant impact on the efficient production of such steels in terms of poor welding quality,low pickling efficiency,and unstable rolling during actual production.This paper analyzes and improves the influence factors on welding quality from welding process,the effect of hot rolling material conditions on pickling efficiency,as well as stable rolling for this type of steel to achieve 30%increase in production efficiency while ensuring product quality.
