TAPPING METHOD OF CONVERTER FOR REDUCING NITROGEN IN MOLTEN STEEL

摘要

The present invention relates to a steel tapping method for minimizing the amount of remaining nitrogen in a slag flowing into molten steel when the molten steel is discharged from a converter. Provided is a steel tapping method of a converter for reducing nitrogen in molten steel, including the following steps of: tilting a converter to the opposite side of a tapping outlet, after blowing the converter; excluding only the slag which flowed out through an insertion hole of the tilted converter, and which is formed on top of the molten steel; and tilting again the converter to the side of the converter tapping outlet to discharge the molten steel, pure from the slag, through the tapping outlet and into a ladle after. [Reference numerals] (AA) Start; (BB) End; (S10) Moving a converter in a direction to the other side of a converter tapping outlet; (S20) Eliminating slag through a converter charging hole; (S30) Eliminating only molten steel inside the converter to the tapping outlet by moving to the direction of the converter tapping outlet
