[0125] use figure 1 The shown converter-type refining furnace with a capacity of 330 tons has implemented the molten iron pretreatment of the present invention (Examples 1 to 3 of the present invention) and the molten iron of the conventional method of measuring the slag height through the slag level of the microwave oven but not controlling the slag height Pretreatment (Comparative Example 1, Comparative Example 2) was performed 20 times each. The target value of phosphorus concentration in molten iron at the end of the pretreatment was all set to 0.030% by mass.
[0126] In Example 1 of the present invention, a microwave oven slag level gauge is used to measure the slag height in oxygen blowing in the desiliconization treatment, and at least one of the oxygen feeding speed from the top blowing lance, the height of the lance, and the gas flow rate for stirring is measured. Adjust the ratio of the measured slag height to the height of the melting chamber in the furnace so tha...
