Abstract

PURPOSE:To normally suck exhaust gas, by preventing the simultaneous suction of air and the dispersion of gas in a converter outside the furnace by forecasting the quantity of gas generated in the furnace in consideration of the quantity remaining in the furnace due to the formation of slag, etc. among fed oxygen in the operation of the converter. CONSTITUTION:Oxygen is blown from the upside to hot metal la in a converter 1 from a run- through 2, and oxidation refined, thus producing steel. In this case, exhaust gas information is obtained from sucked exhaust gas flow rate by an exhaust gas flow meter 13 and the analysed value of exhaust gas by an exhaust gas analysis meter 11. The quantity of blowing-in oxygen is obtained at an oxygen flow meter 10 and by-raw material information at a by-raw material charging transmitter 9, both are fed to an electronic computer 21, and signals from a gas pressure transmitter 12 of a furnace port, a gas pressure transmitter 19 at a skirt location and the opening transmitters 14, 14a of dampers 16, 18 in a duct 4 are input. Exhaust gas is calculated by means of the computer 21 from these signals, a dust collecting damper 16 and a damper 18 of a suction fan are controlled by the value, and a large quantity of air is absorbed at the furnace port of the converter or exhaust gas comtaining CO is adequately sucked so that the gas may not be dispersed outside a hood 3.
