Development of Shape Control in Plate Rolling

Abstract

Newly developed plate shape control system, using attached shape meter, was put in service in Mizushima Works, Kawasaki Steel Corp. This system consists of (1)Sensors ; attached shape meter, multi head γ ray thickness meter (crown meter) (2)Actuator ; oil pressure type work roll bending device and (3)Models : shape prediction model, plate crown prediction model.
The closed loop, comprising attached shape meter and work roll bending system based on the shape prediction model, characterizes this system.
Introduction of this system, enables the improvement of flatness and plate crown accuracy, which meets ever upgrading customer's demand and also yields improvement and chance free rolling.
This report describes the following terms ;
(1)Specification of shape meter and work roll bending device.
(2)Algorithm of shape control system.
(3)Results.
