Roll matching technology of Sendzimir 20-high mill
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.
