  • Patent number: 3934638
    Abstract: A process of continuous casting a ferrous metal bloom or billet free of axial looseness and voids and having good chemical homogeneity in the central axial zone in which a molten ferrous metal is maintained in a tundish which supplys the molten metal to a continuous casting mold through a mold feeding nozzle at a superheated temperature above the liquidus temperature of the ferrous metal sufficiently high to avoid objectionable freezing or skulling in both the tundish and the mold feeding nozzle but not at such an elevated temperature that the molten metal cannot be cooled in the continuous casting mold to at least the liquidus temperature of the ferrous metal before the metal descends into the deep liquid core zone of the continuous casting.
