冷连轧机组末机架轧制参数综合设定技术的研究

针对冷连轧机组的生产工艺特点,以带材出口前张力横向分布均匀(即板形良好)作为优化目标函数,建立了一套冷连轧机组末机架轧制参数综合优化数学模型,并将其应用到宝钢冷轧薄板厂1220五机架冷连轧机组末机架压下量、前后张力、弯辊力等主要轧制参数的综合设定,取得了良好的使用效果,大大提高了成品带材的板形质量。

RESEARCH OF COMBINED SETTING TECHNOLOGY ABOUT ROLLING PARAMETER OF FINAL STAND IN TANDEM COLD MILL

According to the characteristic of production technology in tandem cold mill,a set of mathematical model about the combined optimization of rolling parameter of final stand in tandem cold mill was set up by taking the transversal uniform distribution of belt front tension in outlet as the object function.The model was used for the combined setting of the main rolling parameters of reduction amount,front tension & back tension and roll bending force in the final stand of 1220 five-stand tandem cold mill in the thin strip factory of Baosteel,a better usage effect was obtained,the strip shape quality of finished belt was improved greatly.
