Abstract
An electromagnetic levitation type continuous metal casting apparatus includes a molten metal storing furnace for holding and storing a molten metal, a casting vessel for upwardly receiving and holding the molten metal in the form of an upwardly moving molten metal column, a displacer block for controlling supply of molten metal from the storing furnace to the casting vessel cooling means unified with the casting vessel and disposed around the outer periphery of the casting vessel for cooling and solidifying the upwardly moving molten metal column, alternating electromagnetic levitation and containment field generation means surrounding the casting vessel and cooling means disposed around the outer periphery thereof for generating an alternating electromagnetic field for electromagnetically levitating and containing the upwardly moving molten metal column while it is in the casting vessel, a molten metal supply path for supplying the molten metal to be cast from an inlet relatively high upon the side wall of the molten metal storing furnace vessel, a heat exchange (cooling) means wherein the direction of flow of the coolant in the cooling means is reversed in the area adjoining the…
