Abstract

PURPOSE:To pass a stock to be rolled stably and to improve the accuracy of the thickness and width of sheet by controlling the roll speed of the (i)th stand so as not to reduce tension by over a prescribed value when the rolling load of the (i)th stand is tensionless. CONSTITUTION:The variation of rolling load of the (i)th stand is generated between the (i)th stand and the (i+1)th stand when the stock to be rolled is bitten into the (i+1)th stand. Therefore, when the stock 10 to be rolled is bitten into the (i+1)th stand or when the state of super-tension occurs during rolling is continured, the state of super-tension can be mitigated by increasing the roll speed of the (i)th stand.
