Abstract

PURPOSE:To substantially decrease the S content of molten steel by circulating the molten steel through a ladle, molten steel rising pipe, vacuum refining chamber and molten steel falling pipe in succession; vacuum refining it with covering its surface with refining slag in the refining chamber; and then removing slag with keeping the vacuum state after refining.
