Modeling and Control of Multi Stage Rolling Mill Process. Sheet Rolling Mill processes involve progressive thickness reduction of continuous sheet metal in multiple stages. Some of the control variables of interest are exit thickness, throughput and the tension in the sheet as it passes from one stage to the other.

2. TANDEM COLD MILL MODELING The cold rolling tandem mill is typically made up of ﬁve stands, associated in cascade, traversed by the product steel strip which passes through their independent driven work rolls. The objective of such process is to reduce strip thickness and to obtain a desired product having certain thickness, rigidity and ...

Roll-gap model The roll-gap model is further differen-tiated into a model for reduction mills and for skin pass / temper mills / foil mills. For reductions of more than about five percent and a larger ratio be-tween the mean gauge und contact length, a roll-gap model based on the classical circular arc theory of Ford, Ellis and Bland is used.

Shape setup model (SSM) plays a critical role to achieve satisfactory precision of strip shape in hot strip mill process (HSMP). However, for the design of shape model, the lack of systematic shape theory restricts the high accuracy of strip shape. In this paper, the procedure of SSM will be generally introduced and practically demonstrated with a real HSMP producing …
