Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a large-scale stainless steel-copper alloy composite plate asynchronous hot rolling process to solve the metallurgical problems of easy oxidation of the metal material surface and composite interface existing in the existing stainless steel-copper alloy rolling composite process. The combination rate is not high, the interface is easy to peel off or the peel strength is low, and it needs to be formed after multiple passes of rolling, so it is impossible to prepare large-size long composite plates.
