| 摘要 |
An electromagnetic levitation type continuous metal casting apparatus is disclosed, which comprises 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, 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 unified with the casting vessel and disposed around the outer periphery thereof for generating an alternating electromagnetic levitation and containment field, the alternating electromagnetic field electro-magnetically levitation and containment the upwardly moving molten metal column while it is in the casting vessel, a tube shaped molten metal supply path for supplying the molten metal to be cast from the molten metal storing furnace to the casting vessel, and high frequency heating means disposed on the outer periphery of the tube shaped molten metal supply path, means are provided in the coolant path wherein the direction of flow of the coolant in the cooling means is inverted at the area where the second coil from the lower end of a plurality of coils comprising the generating means for generating the alternating electromagnetic levitating and containment field, is disposed, the tube shaped molten metal supply path having at a bend section upwardly to the casting vessel and an appendix section secured to the casting vessel on the side thereof opposed to the molten metal storing furnace.
