Abstract
The present invention provides a method and a system for controlling strip thickness in rolling mill, especially adapted in the case where material is rolled by a tandem rolling mill. According to the present invention, the change in the strip thickness from one sampling epoch to another is calculated on the basis of two sampling values, i.e. strip thickness and strip thickness deviation, at the entrance side of a mill stand; the press-down speed and the workpiece tension are determined according to such a condition as to minimize the calculated change during the sampling period; and the press-down speed and the interstand tension are regulated by the thus determined mill speed and tension when a certain portion of the strip reaches the stand bite of the next mill stand.
