Abstract
A process and apparatus for producing a metallic laminar composite material utilizes a pressure tank, a ladle, and a dip tube for transferring molten metal into a mold which has a metallic plate suspended within it. The molten metal is supplied by the ladle and the dip tube in such a way that slag and scum existing on the surface of the molten metal are not introduced into the mold. Prior to introducing the molten metal into the mold, the mold is purged with an inert gas to prevent oxidation of the surface of the metallic plate. The mold is made of freely movable carbon segments which permit easy assembly and disassembly of the mold for varying the size of the molding chamber.
