Converter inactive lime steelmaking method

The invention provides a converter inactive lime steelmaking method, belongs to the field of steelmaking industry and aims at solving the problem in the existing steelmaking process through improvement of steelmaking production process. The converter inactive lime steelmaking method comprises the steps of selecting required limestone particle size and CaCO3 components according to the quality situation of raw materials, feeding qualified raw materials to a material loading system, obtaining the adding amount according to the temperature and components of molten iron and slag basicity of steel grade and selecting slag reserving operation mode according to the production status and furnace condition. The converter inactive lime steelmaking method is simple in operation, omits the lime kiln calcination technological process required by inactive lime production, and saves the cost of the lime kiln technological process. The limestone serves as an active lime raw material and has a congenital advantage in price. B
