Title:
ROLLING MILL
Document Type and Number:
Japanese Patent JPH05237511
Kind Code:
A
Abstract:

PURPOSE: To reduce a thrust given to work rolls by crossing a pair of work rolls with a pair of backup rolls and making a cross angle between the backup rolls smaller than a cross angle between the work rolls.

CONSTITUTION: Since the work rolls 1, 2 are inclined to both rolled stock 10 and backup rolls 3, 4, the work rolls 1, 2 receive thrusts F1, F2 opposite to each other from both rolled stock 10 and backup rolls 3, 4, but since the cross angle θ1, between the backup rolls is set smaller than the cross angle θ2 between the work rolls, the relative inclination θ5 of the work rolls 1, 2 to the backup rolls 3, 4 decreases, therefore, the thrust applied by the backup rolls 3, 4 to the work rolls is reduced to as much as the thrust given from the rolled stock 10 and both thrusts are cancelled to diminish the thrust applied to the work rolls.
