METHOD FOR EFFICIENTLY REFORMING SLAG DURING TAPPING

摘要

PURPOSE: A method for reforming slag of molten steel is provided to promote melting of slag modifier by injecting recarburizer into molten steel during tapping. CONSTITUTION: In a molten steel refining process for reforming molten steel slag by injecting slag making material into molten steel while discharging molten steel into ladle from converter, the method for reforming slag of molten steel comprises the process of injecting recarburizer containing 90% or more of carbon content into ladle in an injection quantity of 5 to 20 kg/250 to 270 ton of molten steel after a time point when 4/5 of the molten steel is discharged.
