Abstract

PURPOSE:To minimize the fluctuation of the furnace pressure, and to improve the heat at value of recovered gas per unit product, in the noncombustion recovery apparatus for the converter gas, by adjusting the oxygen feed rate correspondingly to the timing of charge of the temperature adjusting coolant for generating the oxygen gas within the molten steel like as the iron ore, the lime stone, etc. CONSTITUTION:At smelting the steel by the converter, the oxygen feed rate is adjusted corresponndingly to the amount and charging velocity of subsidiary material like as the iron ore, mill scale, lime stone, etc., to generate the oxygen etc., within the molten steel. Hereby, the amount of gas generated in the furnace is kept constant, the fluctuation of the furnace pressure is restricted to a small value, the leak of gas or sucking of outside air through the gap between the skirt and the furnace port is prevented, and the useless combustion of the generated gas is prevented; hereby, the heat value of the recovered gas per unit product can be improved.
