ABSTRACT:
A continuous cast method comprises continuously supplying molten metal from a tundish through a break ring to a cooled mold having an inlet and an outlet. A cast section is formed by continuously cooling the molten metal in the mold and starting the solidification of the molten metal below its surface and intermittently withdrawing the cast section with respect to the mold through its outlet. During continuous casting, a sealing gas having a pressure higher than atmospheric and soluble in the molten metal is constantly supplied to the entirety of the contact area of the mold and the break ring.
