  • Refinement Of Pig-Iron, Manufacture Of Cast Iron, And Steel Manufacture Other Than In Revolving Furnaces (AREA)

Abstract

PURPOSE: To stably manufacture a low N steel by carrying out oxidation refining of molten pig iron for steel-making with alkali metal cpds. , and at the same time, to decrease the P and S contents of the molten pig iron, thereby resulting in operation of a converter with a minimized amt. of slat.
