六辊可逆冷轧机道次量综合优化技术的研究
Research on the optimization technology of six-roll reversible cold rolling mill pass quantity
摘要
Abstract
In the high-speed rolling process of a six-high single stand reversible rolling mill,the reasonable setting of rolling pass quantity directly affects the distribution of exit strip shape and the stability of rolling mill,as well as production efficiency andenergy consumption of rolling mill.Although high-speed rolling is fast,the average pressure reduction per pass is limited and relatively small under high-speed rolling conditions.To achieve consistent exit thickness,need to increase corresponding passes number.For reversible rolling mills,increasing passes number means significant increase of energy consumption for the entire unit.To the problems of plate shape and high energy consumption in the high-speed reversible rolling process,the rolling pressure and power of the last three passes were effectively reduced by optimizing parameters such as the front and rear tension and rolling speed of each pass,the objective functions of shape control and power control for each pass are established,and after weighted calculations,which developed a comprehensive optimization and setting technique of rolling schedules that object as rolling power uniform each pass,while also taking into factors such as shape control,rolling stability,and surface defect prevention.This optimization technology has been applied to the production of strip steel in a single reversible cold rolling mill in China.The plate shape quality of the exit strip steel has been improved,the slip rate has been effectively reduced,and the production efficiency has been improved.关键词
