Zusammenfassung:A system and a method provided for facilitating hot strip rolling of steel including Cold Rolled Non Oriented (CNRO) grade steel in hot strip rolling mill. The present system and method is adapted to automatically and efficiently calculate draft and speed schedule for hot rolling of CNRO grade steel in the hot strip rolling mill in accordance with flow stress characteristics of the steel. The system and the method automatically and correctly determine the mill calibration parameters like roll force, torque, power, finishing stand temperature before entry of the steel to the stands and drive the rolling operation without slowing the speed and without increasing the roll gap values.
