The invention belongs to the technical field of double-metal composite material rolling, and in particular, relates to a method for improving forming performances of a double-metal composite plate through adding pulse current in a rolling process. The method comprises main steps of treatment of coating layer metal and base layer metal before rolling, communication of the pulse current on a metal plate and rolling through startup of a rolling mill. The rolling method of the double-metal composite material is to apply the pulse current to double metal in the rolling process; and positive and negative output ends of a pulse power supply are connected with an electric brush to form a closed loop. The method has the following beneficial effects: the plasticity of the double-metal plate is improved; the rolling force is reduced; the edge cracking of the composite plate is inhibited; the element dispersion of the coating layer and base layer metal is promoted; the energy barrier is overcome;the metal atom dispersion efficiency is improved; the bonding strength is improved; and the rolling productivity is improved.
