抄録

Experimental and theoretical studies were carried out to understand the mechanism of deoxidation with soluble gas in molten steel in an RH degasser.<BR>A large quantity of soluble gas was dissolved in molten steel, after decreasing the pressure rapidly during degassing, inclusions were trapped by fine bubbles and are then floated and removed. Experiments demonstrated the deoxidation rate was larger than that of conventional argon gas bubbling. A kinetic model for deoxidation in the RH degasser was developed to estimate the deoxidation rates in a vacuum vessel and in a ladle, and to predict the behavior of oxygen content.
