Abstract

The invention generally relates to a method of controlled rolling of a metal strip moving through a rolling mill. The method comprises: monitoring a plurality of input control parameters; and generating a plurality of responsive operational control parameters in the rolling mill to selectively control the rolling mill and selectively control a plurality of output parameters of the rolling mill. A control system for controlled rolling of a metal strip moving through a rolling mill is also provided.
