Abstract

PURPOSE:To perform a desired temper rolling accurately, by providing the 2nd servo-valve of low press. to a by-path pressurized-oil feeding path provided for a primary servo-valve to switch paths for pressurized oil feeding path mutually. CONSTITUTION:A pressurized-oil introducing pipe 9 is provided as a by-path for a servo-valve 8 and the low-press. 2nd servo-valve 10 of which the press. is lower than that of the valve 8 is provided so as to switch the paths by solenoid valves 11, 12. In ordinary cold rolling; the rolling is performed, by positioning the valve 11 at B side and the valve 12 at A side to control them, and feeding the pressurized oil to an actuator 6 through the valve 8 and a pressurized-oil introducing pipe 7b to actuate a screw-down rack 5. In temper rolling of small rolling force; the valves 11 and 12 are positioned at the sides (a) and (b) respectively to be controlled, and the pressurized oil is fed to the actuator 6 through the valve 10 and the pipes 9, 7b.
