ABSTRACT:
For use in a continuous casting apparatus wherein molten metal flows through a die progressively and is solidified in the die and withdrawn from the die, a die and cooling assembly comprising a tubular die having an external tapered surface which is uniformly tapered radially inwardly in the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 of the die and in substantial contact with the external surface of the die and an annular cooling jacket wall surrounding the cooling sleeve and having portions thereof spaced from the sleeve to define a cooling chamber. At least one coolant inlet is provided to the chamber and at least one coolant outlet is provided from the chamber. The inlet and outlet are spaced axially with the outlet being nearest the upper end of the die where the molten metal enters the die and the inlet being nearest the lower end of the die where the solidified metal leaves the die. The cooling sleeve has a plurality of circumferentially spaced integral ribs extending radially outwardly therefrom into close proximity to the inner surface of the cooling jacket wall such that coolant flows in a thin layer along the inner surface of the cooling jacket and in a plurality of axial paths along the surfaces of the ribs. The ribs are of progressively increasing height circumferentially about the cooling sleeve from the area of the coolant inlet to the area of the coolant outlet.
