The Extrusion of Metals

Abstract

An apparatus and method are described for the extrusion of metal using an apparatus of the "Conform" type. A furnace (1) is used to heat metal to a molten state, and-an electromagnetic pump (4) transfers molten metal from below the level of the surface of the molten metal in the furnace. A transfer tube (3,6) from the electromagnetic pump (4) extends to adjacent an inlet (3a) to the apparatus (3) of the "Conform" type, and a tube (7) of restricted diameter extends from the transfer tube (5, 6) to the inlet (3a), to supply the molten metal from the transfer tube (5, 6) to the inlet (3a).An apparatus and method are described for the extrusion of metal using an apparatus of the "Conform" type.
