Method for refining Molten Steel for controlling phosphorus content in Converter

摘要

that the present invention is directed to a converter refining method, to 2.0 the basicity (CaO / SiO ₂ ) of the slag by maintaining 3.0 to control the phosphorus (P) component in the molten steel to 200 to 300ppm provide a converter refining method which is characterized. ; The invention has the advantage to increase the molten steel of the phosphorus (P) component decreases by controlling the composition of the slag in a converter refining process of the slag basicity (CaO / SiO ₂ ).
