Abstract
PURPOSE: To automatically control the product sheet's thickness to the aim value, and to improve the passableness of sheet in the rolling work, by continuously changing the aim value of the control on the run-out side of each rolling mill during the period from biting the rolled material until its tail passes through, in the hot rolling method in which the thickness monitoring and controlling system is added to the gaugemeter control system.
CONSTITUTION: In above method, the controlling system 11 for distributing the compensational input and the sheet passableness compensating system 10 for each mill are added to the conventional automatic sheet thickness controlling method. And, the controlling system 11 operates the compensational input for improving the passableness of sheet required for keeping the balance between the rolling reductions of each of rolling mills according to the set rolling schedule, against the aim thickness value of the control on the run-out side of each rolling mill of the gaugemeter control system 1 being set according to the rolling schedule calculated depending on the rolled material and the rolling specification. According to this operation, the compensational input is distributed to the controlling system for each rolling mill. Next, the compensating system 10 changes the aim value of the control for each rolling mill according to above distributed compensational input.
