REFINING METHOD OF TITANIUM ADDITION AUSTENITIC STAINLESS STEEL, WHICH PREVENTS THE CLOGGING OF A SUBMERGED NOZZLE IN THE CASTING

摘要

PURPOSE: A refining method of titanium addition austenitic stainless steel is provided to prevent the deformity generating in the surface of product by removing oxide by improving slag property from a group.;CONSTITUTION: A titanium addition austenitic stainless steel method of refining comprises: a step of forming a slag by inserting a flux; a step of bubbling by inert gas in the bottom of a redactor; a step of controlling the weight ratio of CaO/Al2O3 in 1.5~2.0; a step of removing the aluminum oxide produced from the deoxidizing aluminum process step; and a step of using a quicklime(CaO) for the weight ratio adjustment of the CaO/Al2O3.;COPYRIGHT KIPO 2010
