Problems solved by technology
At present, the corrugation rolling force is mainly obtained by finite element method, but the finite element method takes a long time to calculate, and each calculation can only display the results of a specific process, the calculation speed is slow, and the post-processing is cumbersome, which leads to the roll gap in the existing technology. There is a problem with the adjustment

The invention provides a setting method for a sine roll type corrugated roll gap of a metal composite plate. The setting method for the sine roll type corrugated roll gap of the metal composite plate comprises the steps of correspondingly determining the inlet thickness, the outlet thickness, the width and the rolling temperature of a difficult-to-deform metal plate blank and an easy-to-deform metal plate blank according to technological procedure data of a certain pass; detecting the rotating speed of rollers and the inlet speed of the metal composite plate blank to obtain the nominal radius of a corrugated roller, the radius of a flat roller, the friction factor between the corrugated roller and the difficult-to-deform metal plate blank and the friction factor between the flat roller and the easy-to-deform metal plate blank; determining the amplitude of the sine roll type corrugated roller and the number of complete sine waves on the roller, and calculating the time required for rolling a complete waveform; calculating the rolling force at any moment in the sine roll type corrugated rolling process of the metal composite plate by utilizing the functional minimization of the total power of a rolling deformation area; and calculating the roll gap S of the corrugated roll at any moment t according to the rolling force F, according to the actual rolling procedure, the roll gap of a rolling mill is set to be S, and normal production is conducted.
