<p>PURPOSE:To eliminate the deviation of a strip and to perform rolling. CONSTITUTION:An upper and lower backup rolls 21, 22 are arranged in parallel to each other and at right angle to the advancing direction of a steel strip 20; total cross angle theta (=theta1+theta2) is held constant of an upper and lower work rolls 1, 2 against the upper and lower backup rolls 21, 22, and rolling is carried out. If the quantity of deviation detected by a deviation detector 9 on the exit side is in excess of a tolerance, servo valves 7a, 7b, 8a, 8b are controlled by a control panel 10, cross cylinders 5a, 5b, 6a, 6b are operated, and, while the total cross angle theta is held constant, the upper and lower cross angle theta1, theta2 are changed, eliminating the deviation.</p> |
