The invention relates to the technical field of preparation of a bimetallic composite plate, in particular to a method for strongly deforming and rolling a bimetallic composite plate, and aims to solve the technical problems of low bonding strength, large residual stress and serious warpage in an existing bimetallic plate rolling method. According to the technical scheme, a manufactured bimetalliccomposite plate blank is subjected to two passes of rolling, a wave plate rolling mill is adopted for the first pass, the upper roller is a crossed corrugated roller, and the lower roller is a flat roller; and a flat roller mill is adopted for the second pass, and the upper roller and the lower roller are all flat rollers. According to the rolling method, the composite plate with good comprehensive performance of the tensile shear strength and tensile strength in the rolling direction and the transverse direction is obtained, and the residual stress distribution inside the bimetallic composite board can be obviously improved; and by adopting the novel process for rolling the bimetallic composite plate, the bonding strength of the two plates can be improved, the residual stress distribution state is improved, and the plate warpage is reduced.
