Abstract The manufacture of bimetallic composite band includes surface pre-treatment, rolling for composite, heat treatment of composite band and other steps. After the surface pre-treatment, an initial surface adsorption step is adopted to blow nitrogen towards the clean surface of metal and form an adsorbed nitrogen film on the surface of metal. The rolling step for composite is a fast variable-temperature electrically heated one. The manufacture of the present invention has the advantages of simple process, easy operation, low cost, high composite strength, good machinability of the composite band, etc.
