Description

【Technical field】 [0001] The invention relates to the technical field of industrial smelting furnaces, in particular to the technical field of high-efficiency steelmaking converter systems. 【Background technique】 [0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloy as the main raw materials. The steelmaking process is completed in the converter by the physical heat of the molten iron itself and the heat generated by the chemical reaction between the components of the molten iron without the aid of external energy. According to the refractory material, the converter is divided into acidic and alkaline; according to the position where the gas is blown into the furnace, there are top blowing, bottom blowing and side blowing; according to the type of gas, it is divided into air converter and oxygen converter. Basic oxygen top-blown and top-bottom compound-blown converters are currently the most commonly used steelmaking equipment due to their fast product...
