Abstract: PURPOSE:To efficiently produce a high purity molten steel reduced in C, N, and P contents by producing a high carbon metal reduced in P and Si contents in a metallurgical furnace, removing this metal to a movable vessel, and successively carrying out primary decarburization and secondary decarburization. CONSTITUTION:In a top and bottom blown metallurgical furnace, first an iron material containing iron oxide, a carbon material, and a flux are thrown into this furnace while top-blowing oxygen, and the temp. of a molten metal is regulated to 1360-1450 deg.C. Subsequently, the amount of blowing of bottom blown gas is regulated so that T.Fe in the slag becomes 3-9%, and further, a carbon material is thrown so that C concentration in the metal becomes >=3%, by which a high C metal reduced in P and Si contents is produced. Then, the metal is moved into a movable vessel (ladle, etc.) and oxygen blowing is exerted under atmospheric pressure to reduce C concentration to <=0.5% and also to perform denitriding, and further, oxygen blowing is carried out in the same vessel while evacuating the atmosphere to reduce C and S contents and to form a steel with very low carbon content. By this method, the high purity steel reduced in respective concentrations of impurities, such as C, N, and P, can be obtained at a low cost of equipment.
