| titleOfInvention | Hot metal pretreatment method |
| abstract | An object of the present invention is to provide a hot metal pretreatment method capable of reducing the fluorine content of all slag generated by a steel mill and making it harmless by dilution. In the hot metal preliminary treatment in which silicon, phosphorus and sulfur contained in the hot metal are previously removed before charging the hot metal into the steelmaking furnace, the hot metal held in the topped car 6 is scoured without fluorite. After blowing agent 2 with carrier gas 12 through lance 4 and desiliconizing and dephosphorizing, the desiliconized and dephosphorized hot metal is transferred to a ladle, a desulfurizing agent containing fluorite is added and mechanically stirred. In addition to desulfurization, the fluorine-containing slag generated by the desulfurization is used as a part of the raw material charged in the blast furnace, and the fluorine of the fluorine-containing slag is diluted and discharged from the blast furnace as blast furnace slag having a fluorine content of 1000 ppm or less.
