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.

Abstract: This invention relates to a process for preventing the rephosphorization phenomenon in which, during the production of killed steel in a basic electric furnace, a part of the phosphorus oxide formed and removed in the oxidizing period is reduced in the subsequent deoxidizing period to increase the phosphorus content of the melt again. This process comprises subjecting the melt to oxidizing refinement in the electric furnace, pouring the resulting undeoxidized melt and slag into a ladle, removing the slag of the oxidizing period completely from the melt either by skimming it off or by pouring only the melt into another ladle, and then deoxidizing the melt in the ladle. According to this process, the rephosphorization phenomenon attributable to the residual slag of the oxidizing period adhering to the wall surfaces of the furnace and/or the phosphorus pentoxide (P.sub.2 O.sub.
