HOT METAL DECARBURIZATION METHOD FOR STAINLESS STEEL

摘要

The present invention relates to a method for manufacturing a stainless steel using a hot metal produced from a shaft furnace. The method includes: a preliminary treatment step in which a hot metal is dephosphorized, a converter decarburizing step for decarburizing the hot metal in a converter. A ferroalloy is inserted when carbon content of the hot metal is 0.8-1.2 weight% during the converter decarburizing step.
