| abstract | (57) [Summary] [Object] The present invention relates to hot metal dephosphorization treatment and decarburization treatment in a converter, and enables hot metal dephosphorization and desulfurization refining in a state where heat loss is the smallest and scrap consumption is the largest. The present invention provides a converter steelmaking method. [Configuration] In the upper bottom blown converter refining apparatus, molten iron受銑step (step 1), the ratio L / L 0 of the top-blown gas the molten iron surface recess depth L and Yokufuka L 0 by 0.3 to 0.7 Hereinafter, hot metal dephosphorization desulfurization step (step 2), slag discharge step (step 3), step for refining under the condition that the oxygen supply rate F (Nm 3 / (min · ton)) is 0.3 or more and 0.9 or less The same process as in No. 2 for decarburizing by supplying oxygen from the upper blowing lance at an L / L 0 of 0.5 or more and 0.8 or less and an oxygen supply rate of 2 × F or more and 10 × F or less (step 4). And carry out. here, The upper blowing lance is a porous lance composed of two types of nozzles having different diameters, and in step 2, oxygen is supplied from a small diameter nozzle. Nitrogen is supplied from a large-diameter nozzle, and oxygen is supplied from all nozzles in step 4. |
