Title:
DEVICE FOR ADJUSTING ROLL POSITION OF 2-ROLL TYPE STAND FOR VERTICAL ROLLING MILL BALANCEDLY
Document Type and Number:
Japanese Patent JP3378453
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make operation simple and to reduce the possibility of damage during working by arranging the stationary part of a tie rod which is protruded from a capsule by penetrating a sleeve and passing through the stationary part on the opposite side of an engaging member.
SOLUTION: Four hydraulic capsules (two capsules per each roll) of each stand are formed from a stationary part consisting of a flange 1 and members 1 and 5 and a movable part consisting of members 2, 4 and 6. The relative movement of the two parts is achieved by supplying oil into two oil chambers formed by halving the inside of the capsule by a piston 2 and discharging the oil from the chambers. Adjustment of position is executed by a servo valve which is controlled by a detector for the linear position which is usually formed as an electronic position transducer 7.
