The invention discloses a working roller matching method and device, equipment and a medium. The working roller matching method comprises the steps that a roller matching instruction triggered by a user is received; in response to the roller matching instruction, the actual on-machine frequency, the actual abrasion loss and the actual abrasion width upper limit corresponding to each set of working roller in the available roller pool are determined; the corresponding maximum target width in all the to-be-rolled strip steel in the current plan list and surface quality demand parameters for the to-be-rolled strip steel are obtained; according to the actual loading times, the actual abrasion loss and the actual abrasion width upper limit corresponding to each set of working roller and the maximum target width corresponding to the current plan list, the loading priority corresponding to each set of working roller is determined; and according to the maximum target width, the surface quality demand parameters and the on-machine priority corresponding to each set of working rollers, the working rollers used for rolling the to-be-rolled strip steel corresponding to the current plan list are screened out from the available roller pool. The roller matching precision and efficiency are improved, the production efficiency is improved, and the quality and rolling stability of hot-rolled products are guaranteed.

The invention discloses a preparation method of an aluminum foil blank for a high-strength 8021 battery soft package, and belongs to the technical field of aluminum alloy processing. According to the method, an 8021 alloy cast ingot serves as a raw material, hot rolling, segmented cold rolling, medium and low temperature intermediate annealing, finish rolling and other procedures are carried out, and the high-strength aluminum foil blank is prepared by optimizing rolling reduction distribution and roll surface roughness. The tensile strength of the obtained blank is larger than or equal to 170 MPa, the plasticity and the surface quality are excellent, the process energy consumption is lower, equipment does not need to be newly added, and the method is suitable for industrial production of the aluminum foil blank for the high-end soft package lithium battery aluminum-plastic film.
