Abstract

PURPOSE: To prevent the spalling of refractories due to gas and the local burningout due to the turbulent flow of molten steel, to decrease the cost of equipment for refractories, etc. and to improve the productivity, by blowing-in an inert gas from the bottom of the ladle, at the vacuum degassing of the molten steel.
