Method of producing layer-like clad metal materials |
摘要 |
A method of producing layer-like clad metal materials is disclosed. The layer-like clad metal material is produced by applying an organic substance consisting mainly of carbon and hydrogen to the surface of a metallic core material having at its surface substantially no oxide film to form a coating film having a thickness of 50-3,000 mu m, placing said core material in a casting mold, pouring a molten metal having the same or different composition around said core material into said mold by a bottom pouring process to form a clad metal ingot, subjecting said ingot to slab rolling or forging to form an intermediate product, and then subjecting said intermediate product to a hot working and, if necessary, a cold working.
