Control system of material flow in hot rolling-mill drive

Abstract

The problem of forming and wind up loop in a bar, rod and profiles hot rolling mills is considered. A new conception for process forming and wind up loop are presented. Application of modern control theory has led to construction of simple special system (observer) in which of the basis of some state variable mensurations, torque load can be estimated. Also a simplified algorithm of material flow control are presented. The given algorithm structure enables preliminary determined by the range of limited and allowable parameters of rolling-mill line. The describe system are installed in an one rods, profiles and wire rolling-mill in Poland.
