The invention relates to a splashing-preventing smelting control method for smelting of molten high-silicon iron in a converter. The method comprises the following successive steps: controlling of a slagging phase of the converter; and controlling of a normal smelting phase of the converter. In the step of controlling of the slagging phase of the converter, the content of iron oxide in slag and the binary basicity of slag are controlled, oxygen supply is stopped in time according to the volume concentration of carbon monoxide in flue gas, and slagging is carried out; and in the step of controlling of the normal smelting phase of the converter, oxygen supply intensity changes and gun position changes are controlled so as to control the binary basicity of final slag, and normal blowing operation is carried until a terminal point is reached. The method provided by the invention takes a series of control measures and can maintain stability of blowing and effectively prevent splashing of the molten high-silicon iron.
