ABSTRACT:
A continuous casting apparatus wherein molten metal flows through a die progressively and is solidified in the die and withdrawn from the die including a die and cooling assembly comprising a tubular die having an external tapered surface which is uniformly tapered radially inwardly in the direction of movement of metal to the die, a cooling sleeve having an internal surface complementary to the external surface on the die and in substantial intimate surface contact with the external surface of the die and an annular cooling shell surrounding the cooling sleeve and having portions thereof spaced from the sleeve to define a cooling chamber. The die and cooling assembly includes at least one inlet to the chamber and at least one outlet from the chamber, the inlet and the outlet being spaced axially with the outlet being nearest the inlet end of the die into which the molten metal flows. The cooling sleeve has a plurality of circumferentially spaced integral ribs extending radially outwardly therefrom into close proximity to the inner surface of said cooling shell such the coolant flows in a thin layer along the inner surface of the cooling shell along the outer surface of the cooling sleeve. The cooling sleeve has a plurality of axially extending circumferentially spaced axial openings positioned intermediate the inner and outer surfaces thereof and a first and second set of radial passages extends from the cooling chamber to the axial openings.
