PROCESS FOR PRODUCING CLAD MATERIAL AND EQUIPMENT THEREFOR

摘要

A process for producing a clad material, which excels in productivity, facilitating control of the surface condition and flatness of side material member, and which suppresses bonding failure; and equipment therefor. There is provided a process for producing a clad material composed of a core material and, superimposed on one surface or both surfaces thereof, one or two or more side materials, comprising the clad material preparation step of preparing a core material ingot through melting and casting of a metal for core material in the core material preparation step and preparing a side material ingot through melting and casting of a metal for side material with a component formulation different from that of the metal for core material in the side material preparation step; the laminating step of laminating one surface or both surfaces of the core material ingot at given position with the side material ingot as a side material to thereby obtain a laminate; and the cladding hot rolling step of carrying out hot rolling of the laminate to thereby obtain a clad material.
