Abstract

A method of and apparatus for casting steel into a continuous casting mold, wherein the steel is introduced into the casting head to a point beneath the liquid metal pool and the steel, prior to its departure out of a pouring tube, is treated with an inert gas while forming small gas bubbles. The resultant steel-gas mixture during its outflow into the metal pool in the form of a thin, coherent fan or pattern is simultaneously introduced downwardly as well as also laterally. The pouring tube possesses an outlet opening in the form of a downwardly and laterally extending slot and a gas infeed means above such outlet opening.
