Method for Preventing Slag Inclusion in Converter Steel Tapping

摘要

The present invention prevents the outflow of slag into the molten steel during take-ray after the steelmaking process of tapping, the converter refining relates to a method of, using the additives that are added to the converter slag created in the liquid phase with a solid phase which is cured by Kim in the slag at the time of taking discrete ray converter tapping operation without having an outlet for the refining equipment or materials to to provide a method capable of preventing, has its purpose. ; The present invention is a low melting point of the slag in the slag to be added to the converter after blowing end carbon [C] in the reaction with the iron oxide slag and a step of modification of the melting point of the slag; ; to make the slag phase of the total was added to the dolomite in gyeongso modified as shown in the slag to a high body; And ; by blowing an inert gas rinsing (Rinsing) which when tapped converter comprises a method for preventing and slag inclusions to step into that subject matter.
