Abstract

PURPOSE:To sufficiently desulfurize molten steel by regulating the ambient press. of a ladle so that the molten steel is fed to a refining chamber kept under an inert gas atmosphere through a molten steel rising and falling pipe and then covering the surface of the molten steel with refining slag so as to perform refining and remove slag.
