The invention relates to a method for inhibiting the splashing in a
steelmaking process of a converter, which belongs to the field of converter
steelmaking. The method comprises the following steps: determining an appropriate addition amount of waste steel cold material and an addition amount of first batch materials for blowing according to the temperature, components and
slag content of molten iron entering the converter as well as the
slag residual situation of the previous process, enabling the
alkalinity range of the steel
slag to be 1.4 to 1.9 when an oxidation period of
silicon and
manganese is ended, wherein the content of MgO in the slag is 5 to 7 percent, the content of TFe is 18 to 24 percent, and the temperature of the molten iron is 1390 to 1420 DEG C; at a first carbon /
phosphorus oxidation reaction selection point, adding a slag making material comprising
calcium and
magnesium in different batches for multiple times as well as a cold material comprising the
iron oxide, wherein at the second carbon /
phosphorus oxidation reaction selection point, the
alkalinity range of the steel slag is 2.8 to 3.5, the MgO content in the slag is 7 to 10 percent, and the content of TFe is 15 to 20 percent; and in the later period of the blowing, operating by virtue of a pressure gun. By adopting the method, a slag making process is ensured to be adaptive to a reaction process of themolten iron in the blowing of the converter, so that the air permeability and
viscosity of the furnace slag in the blowing process can be matched with the
reaction rate of carbon removal,
silicon removal and
manganese removal of the
molten steel, and the splashing problem in the
steelmaking process of the converter is solved.
