Abstract
PURPOSE:To effectively execute decarbonized-refining of molten iron by shaking a converter at the time of producing the molten steel by blowing oxygen into the molten iron in the oxygen top blowing converter, to form a fire spot on the whole surface of the molten bath. CONSTITUTION:The molten iron is charged into the oxygen top blowing converter 12 providing tuyere bricks 14, 16, and oxygen gas is blown on the surface of the molten iron from an oxygen top blowing lance 20, and C in the molten iron is oxidized and decarbonized by the oxygen gas while stirring the molten iron by blowing N2 gas from the tuyere bricks 14, 16, to refine into the molten steel. In this case, in order to widely develop the fire spot, at where the decarbonizing reaction is generated by blowing the oxygen on the molten iron surface, the converter is shaked at about 30 deg.C angle A toward the F direction of front and rear of the converter 12. The fire spot is formed in the wide range on the molten iron surface, and the molten iron is refined into the molten steel at good yield of the oxygen for a short time.
