Development of the Plan View Pattern Control System in Plate Rolling

Abstract

In plate rolling, it has been sought for many years to make plates rectangular as correct as possible, as one of the methods to improve the yield. MAS rolling (Mizushima Automatic Plan View Pattern Control System) has been developed as a completely new method to make the plan view pattern into a rectangular shape. To improve the controlling accuracy of the MAS rolling system, the following techniques also have been developed.
(1) Plan View pattern prediction models which also calculates the width gain in the MAS rolling.
(2) Application of AG (Absolute Gauge)-AGC (Automatic Gauge Control) to the thickness profile control of the MAS rolling.
This report also describes the different width rolling as an application.
