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.

La présente invention concerne un procédé destiné à produire un matériau plaqué, qui permet une excellente productivité, facilite le contrôle de l'état de surface et de la planéité d'un élément de matériau latéral, et élimine un défaut de liaison, ainsi qu'un dispositif correspondant. Le procédé destiné à produire un matériau plaqué composé d'un matériau noyau et, superposés sur une de ses surfaces ou les deux, d'un ou de plusieurs matériaux latéraux, consiste à préparer un lingot de matériau noyau par fusion et moulage d'un métal de matériau noyau et à préparer un lingot de matériau latéral par fusion et moulage d'un métal de matériau latéral ayant une formule de composition différente de celle du métal de matériau noyau ; à stratifier une ou les deux surfaces du lingot de matériau noyau à une position donnée avec le lingot de matériau latéral en tant que matériau latéral pour obtenir ainsi un plaqué ; et à réaliser un laminage à chaud du plaqué pour obtenir ainsi un matériau plaqué.
