| abstract | The present invention efficiently can carry out dephosphorization refining when providing the refining of Decarburising and refining and dephosphorization, the manufacture molten steel for carrying out molten iron simultaneously in converter, the converter steel making method that the method that proposes than ever is favourable.The present invention is a kind of converter steel making method, in the method, the supply gas oxygen in converter, carry out adding the powder dephosphorization refining agent containing CaO while the Decarburising and refining of molten iron, make the dephosphorization refining agent scorification, form slag, and dephosphorization is carried out while to above-mentioned molten steel decarburization, by above-mentioned cast iron melting molten steel, wherein, above-mentioned dephosphorization refining agent is set to be supplied to molten iron level together with least more than one gas jet from above-mentioned top-blown spray gun, and dynamic pressure when impacting above-mentioned molten iron level from the gas jet of above-mentioned top-blown spray gun is controlled below appropriate value on the basis of the dynamic pressure that the kinetic energy of the adjoint above-mentioned dephosphorization refining agent of quantitative assessment causes rises. |
