Abstract
A continuous casting apparatus comprises continuously supplying molten metal from a tundish to a cooled mold having an inlet and an outlet at least through a break ring, forming a cast section 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 being soluble in the molten metal is invariable supplied to the entirety of the contact area of the mold and the break ring.
