Method for manufacturing clad material and equipment for manufacturing the same

A method for manufacturing a clad material composed of a core material and one or more skin materials that are superposed on either one or both faces of the core material, the method for manufacturing the clad material comprising:

• a core material preparation process where an ingot for core material is manufactured by melting, mixing and casting a metal for core material in a core material preparation process;
• a skin material preparation process where an ingot for skin material is manufactured by melting, mixing and casting a metal for skin material different from the core material in their component compositions;
• a superposition process where the ingot for skin material is superposed as a skin material at a predetermined position of either one or both faces of the ingot for core material to manufacture a superposed material;
• and
• a clad hot-rolling process where the superposed material is hot-rolled to manufacture a clad material,
• wherein, in the skin material preparation process, at least one of the skin materials is manufactured by a slice process where an ingot for skin material manufactured by being melted, mixed and cast is sliced into a predetermined thickness,
• wherein equipment for manufacturing the skin material comprises a casting apparatus which melts and mixes a metal for the skin material different from the core material in their component compositions, and casts the skin material;
• an ingot-cutting apparatus which cuts an ingot for skin material which is cast by the casting apparatus;
• and a conveying apparatus which conveys the ingot for skin material among each apparatus, wherein the ingot-cutting apparatus is a slicing apparatus which slices the ingot for skin material into a predetermined thickness.
