STUDY ON THE EFFICIENCY PRODUCTION OF DP IN PICKLING-MILL LINE
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.
