Background
The rolling mill deforms the metal material by strong pressure to obtain the machine with the shape of the required material, and can be used for manufacturing various sectional materials and blanks. Most of the traditional rolling mills are provided with two working rolls and a plurality of supporting rolls, the plate enters a rolling area under the friction force of the two working rolls, the two working rolls apply rolling force to a rolled piece, and the rolled piece is deformed in the rolling area to obtain a shape required by production.
The shear stress of the plate during deformation is increased by utilizing the difference of linear speeds when the upper surface and the lower surface of the plate are in contact with the roller during asynchronous rolling, so that the rolling of difficult-deformation metals and thin strips is facilitated; meanwhile, the asynchronous rolling can obviously reduce rolling pressure and rolling torque; in addition, in clad plate rolling, asynchronous rolling can greatly improve the degree of warping of the clad plate by "rubbing rolling". Therefore, the accuracy of the speed ratio of the upper roller and the lower roller in the asynchronous rolling process directly determines the accuracy and the shape quality of the product.
Currently, an asynchronous rolling mill generally directly controls two three-phase motors by a controller to achieve a target speed ratio. From the mechanical characteristic of the motor, it can be seen that the rotational speed changes when the load changes. When the asynchronous rolling mill works, the friction force between the upper roller and the lower roller is inconsistent with the friction force between the upper surface and the lower surface of the plate, so that the load of the upper roller and the lower roller is different, the rotating speed is changed, and the whole asynchronous rolling process cannot be completed under a constant different speed ratio.
