Abstract

PURPOSE:To improve the ability to control the crown, etc., by installing apparatus for loading the bending force on upper and lower work rolls, etc., through upper and lower backup roll chocks, upper and lower backup rolls, and upper and lower intermediate rolls. CONSTITUTION:In the case of rolling the strip, the rolling force acts between the upper work roll 4 and the lower roll 17, and causes a large deflection in these work rolls. For the purpose of correcting this deflection, a bending force is loaded on upper and lower work rolls 4 and 17 by each of hydraulic cylinder and screw; hereby, while controlling the deflection of upper and lower work rolls, the rolling of the strip is performed. The bending force P to be loaded on upper and lower work rolls 4 and 17 is given by P=P1+P2+P3, in which P1 is the bending force by the hydraulic cylinder 3 or 9,16, or 22, P2 is the bending force by the screw 11 or the hydraulic cylinders 6,19, or 24, and P3 is the bending force by the screw 15 or the hydraulic cylinder 28.
