METHOD OF WORKING ROLL DEFLECTION ADJUSTMENT

摘要

A method of working roll deflection adjustment includes working and back-up rolls with cushions, hydraulic cylinders for counter deflection of working rolls mounted on the cushions of lower working roll, and a system of supply of high pressure fluid (oil). Furthermore pressure of hydraulic fluid (oil) in the plunger from the entrance side of a strip into the rolls during rolling is changed within(where Q - effort from the plunger on the cushion of upper working roll; Q– effort from the plunger 7 from the entrance side of strip into the rolls).
