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 NARMA-L2, since it can remove the non-linearity of servo system and other disturbances complexities. The …

Hot lubrication rolling is the technology that brings lubricant into the rolling deformation zone in a specific way. By using lubrication rolling, a layer of rolling lubricating oil film can be formed between the roll and the rolled piece, which changes the traditional "metal to metal" direct contact mode between the roll and the rolled piece.
