3. Transfer Learning. Transfer learning is a kind of learning process that uses the similarity of data, tasks or models to apply a model learned in an old field to a new field. Transfer learning has emerged to solve the contradiction in the current state between big data and less annotation and weak computing.

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 ...

1 Introduction. Aluminium cold rolling is a rolling process to reduce the thickness with a further objective of improving the strength, surface finish and formability of the stock by conducting the process of rolling at the room temperature [].Aluminium alloys can be cold rolled down to thickness of around mm. Pure (lowalloy) aluminium can be cold rolled into foil as thin as mm ...

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.
