ABSTRACT:
An improved cooling system for continuous casting through means of a hollow cylindrical die through the top of which molten metal is poured and from the bottom of which emerges a continuously cast bar conforming to the internal configuration of the die. The cooling system includes a cooling sleeve surrounding and continuously engaging the external surface of the die to withdraw heat from the die. The external surface of the cooling sleeve is provided with a series of grooves arranged in a continuous spiral or helix to increase the surface contact with a coolant which is circulated from an inlet upwardly along the cooling sleeve, as well as downwardly along the cooling sleeve to also contact the bar which is cast as it emerges from the die. Surrounding the cooling sleeve is a jacket and the space between the cooling sleeve and the jacket is divided by a partition to direct cool water which may be used as the coolant. In addition, a second coolant circuit is provided which may use a coolant other than water if desired and which directs the coolant through the cooling sleeve through apertures in the die through longitudinal grooves formed on the internal surface of the die so as to cool the lower portion of the die as well as the cast bar emerging therefrom.
