  • Patent number: 4601327
    Abstract: A horizontal continuous casting installation wherein a body of molten metal stored in a tundish is continuously fed through a tundish nozzle connected to the tundish near its bottom and extending horizontally to a mold connected to the forward end of the tundish nozzle coaxially therewith, to perform casting by the mold to produce a strand continuously withdrawn horizontally from the mold. An electromagnetic field generating device is arranged in the vicinity of the tundish nozzle and mold in a manner to enclose same, to generate an electromagnetic force oriented toward the center of a body of molten metal flowing through the boundary and exerted on the body of molten metal. The electromagnetic field generating device is constructed such that a magnetic flux of higher density is generated in a lower portion of the body of molten metal than in an upper portion thereof.

  • Patent number: 4495982
    Abstract: A horizontal continuous casting method for continuously feeding a molten metal stored in a tundish through a tundish nozzle located in the vicinity of the tundish at its bottom to a mold horizontally connected to the tundish nozzle to produce a strand, wherein an electromagnetic field generating device is arranged in the vicinity of the boundary between the tundish nozzle and the mold for exerting an electromagnetic force directed toward a center of the molten metal flowing through the vicinity of the boundary or in a strand withdrawing direction, to separate the molten metal from the inner surface of the tundish mozzle anterior to the boundary with respect to the strand withdrawing direction, to allow the molten metal to come into contact with the inner surface of the mold posterior to the boundary with respect to the strand withdrawing direction.
