A Simulink and mathematical models have been proposed in this study in order to control the thickness in a rolling mill process. The simulation results show that the thickness oscillation can be manipulated with high accuracy by using NARMAL2, since it can remove the nonlinearity of servo system and other disturbances complexities. The proposed NARMAL2 controller model has been compared ...

The material must stay flat during and after the cutting process. The temper mill cannot get the material as flat as a corrective leveler can, and the leveler cannot get the material as stable or provide as fine a hotrolled surface as the mill can. But the two together can produce some superb product.
