[0002] In the production of flat steel-aluminum induction plates, compared to the traditional explosive welding method, the rolling composite method offers advantages such as stable product performance, uniform component thickness, and easy control of residual stress, and has gradually become the mainstream trend in the preparation of layered metal composite materials. In the rolling composite method, the composite ratio of the metal composite plate not only directly reflects the dimensions of the composite plate but also affects the material's processing properties, mechanical properties, and final overall service performance. When using rolling composite technology to produce steel-aluminum induction plates, rapid and high-precision prediction of the rolling force and the thickness of each layer during the rolling process is crucial for rationally formulating the rolling process, controlling the thickness of each layer, and improving product quality.

[0056] In this invention, the method works by regressing the rolling force of the steel and aluminum plates during the rolling process from the estimated target exit thickness, and then determining whether the estimated target exit thickness is reasonable from the perspective of whether the rolling force meets the conditions. Therefore, after determining the target exit thickness of the steel plate and the target exit thickness of the aluminum plate based on the initial thickness of the steel plate, the initial thickness of the aluminum plate, and the target exit thickness of the steel-aluminum induction plate, it is also necessary to determine the rolling force of the steel and aluminum plates during the rolling process.

This information can be obtained based on specific requirements.

[0058] Further explanation is needed to determine the rolling force required for the steel plate during the rolling process:

[0075] The deformation resistance of the aluminum plate is determined based on the initial thickness of the aluminum plate, the target exit thickness of the aluminum plate, the average deformation rate of the aluminum plate, and the rolling temperature of the aluminum plate.

[0097] According to the required rolling force of the steel plate The rolling force required for aluminum sheets Calculate the difference between the two. Determine the difference and The relationship does not meet the judgment criteria. Then, the target exit thickness of the steel-aluminum induction plate is updated again, and the process of determining the rolling force required for the steel plate and the rolling force required for the aluminum plate during the rolling process continues. The process of determining whether the rolling force required for the steel plate and the rolling force required for the aluminum plate during the rolling process meet the preset conditions continues until the judgment conditions are met.

[0098] In addition, the flattening effect on the rolls during metal deformation must be considered, and the flattening radius of the rolls on the steel plate side must be calculated. Because the hardness of steel plate is much greater than that of aluminum plate during heterothermal rolling, the deformation resistance of aluminum plate is insufficient to cause the rolls to flatten. Therefore, the radius of the rolls on the aluminum plate side remains unchanged. In other words, the process of determining the rolling force required for the steel plate and the rolling force required for the aluminum plate during the rolling process is repeated according to a preset number of times. From the second execution to the preset number of times, the required roll radius for the steel plate and the roll radius for the aluminum plate are updated based on the preset strategy for each execution.

[0099] After the preset number of cycles is completed, when it is determined that the rolling force required for the steel plate and the rolling force required for the aluminum plate during the rolling process meet the preset conditions, the predicted target exit thickness of the steel plate and the target exit thickness of the aluminum plate are determined based on the preset number of cycles and the target exit thickness of the steel plate and the target exit thickness of the aluminum plate determined for the first time.
