Abstract

PURPOSE: To improve the precision of the front end thickness of a rolled stock by precisely estimating the outlet side thickness of the front end part of a last rolled stock at each stand and deciding draft positions of the present rolled stock based on the measured draft position at each stand with high accuracy.
CONSTITUTION: The actual information of the last rolled stock is read (A1) to calculate the plate thickness on the outlet side of each stand at the stationary part of the last rolled stock (A2). The variation of thickness of the last rolled stock on the outlet side of the stand from its front end its stationary part is calculated (A3). The plate thickness on the outlet side of each stand at the front end part of the last rolled stock is calculated (A4). Based on the measured draft position of each stand at the front end part of the last rolled stock (A5), the target plate thickness on the outlet side of each stand of the present rolled stock is decided (B2). The rolling load at each stand of the present rolled stock and the last rolled stock is calculated (B3) to decide the draft position at each stand of the present rolled stock (B4). In this way, the precision of the plate thickness of the front end of the rolled stock can be improved drastically.
