Filed: 2020-01-14
Abstract: To accurately estimate phosphorus concentration in molten steel by operation of an MURC method.SOLUTION: An estimation apparatus of phosphorus concentration in molten steel includes a dephosphorization rate constant calculation part and a phosphorus concentration estimation part. The dephosphorization rate constant calculation part calculates an estimated value of the dephosphorization rate constant of the molten steel by using a statistical model using molten steel data relating to the molten steel to be blown in a converter and data extracted from operation data acquired during blowing treatment as explanatory variables. The phosphorus concentration estimation part estimates the phosphorus concentration in the molten steel during the blowing treatment based on the estimated value of the phosphorus concentration and the dephosphorization rate constant before the blowing treatment of the molten steel. The blowing treatment includes a preliminary treatment step including dephosphorization treatment of molten iron, an intermediate slag discharge step performed after the preliminary treatment step, and a decarburization treatment step performed after the intermediate slag discharge step. The explanatory variable includes at least one data representing the amount of slag discharged from the converter in the intermediate slag discharge step.SELECTED DRAWING: Figure 1
