摘要
森吉米尔二十辊轧机广泛应用于硅钢、不锈钢和精密带钢冷轧,其辊系配置直接影响产品精度和生产成本,优良的配辊技术是机组高效运行的基础.针对森吉米尔二十辊轧机,提出了配辊原则及磨削精度要求,建立了坐标系确定各背衬辊初始位置,并对工作过程中各轧辊中心定位进行计算,通过坐标法确定中间辊及工作辊中心坐标.利用建立的方程,对森吉米尔二十辊轧机压下行程与辊缝和辊间隙的关系、辊径补偿轨迹特征进行分析,有助于深入理解森吉米尔二十辊轧机控制特性,提高现场使用效率.
Abstract
The Sendzimir 20-high rolling mill is widely used in silicon steel,stainless steel and precision strip cold rolling.Its roll system configuration directly affects product accuracy and production cost.Excellent roll matching technology is the basis of effi-cient operation of the unit.For the Sendzimir 20-high rolling mill,the principle of roll matching and the requirement of grinding precision are put forward,the coordinate system is established to determine the initial position of each backing roll,and the cen-ter position of each roll is calculated during the working process,and the center coordinates of the middle roll and work roll are determined by coordinate method.By using the established equation,the relationship between the screw down stroke and the roll gap and the roll diameter compensation trajectory are analyzed,which is helpful to understand the control characteristics of the Sendzimir 20-high mill deeply and improve the field use efficiency.
