Abstract

PURPOSE:To continuously cast a casting which is easily press-contacted by rolling by blowing gaseous He depending upon various purposes into the molten steel under casting around a tundish or a mold. CONSTITUTION:In continuous casting of steel, blowing of a gas into molten steel around a tundish or a mold is usually practiced for preventing clogging of an immersion nozzle, flotation of the nonmetallic inclusions in the molten steel or various other purposes. In this case, gaseous He is used for the gas. Thence, the gas captured in an ingot will diffuse into the steel during solidifying and rolling because the radii of He atoms are small. Hence, despite the presence of gas bubbles as black spots 2 in an ingot 1, no gaseous He remains in said bubbles and therefore they are easily press-contacted by rolling, and are entirely harmless as a product.
