Abstract

PURPOSE:To improve dephosphorization reaction by slagging-off acceleration, prevent slopping phenomena and improve yield by controlling the height of a lance and the amount of O2 to be blown based on the periods of one or more of fluctuations in the pressure and flow rate of the exhaust gas from a converter as well as concns. of CO and CO2. CONSTITUTION:For example, in a converter 2 with which the pressure in the furnace is not controlled, the number of peaks of the waste gaseous pressure is detected with a detector 14, and is converted to an electric signal by a converter 16. This signal is inputted to an arithmetic circuit 18. The period of the pressure fluctuations thereof corresponds to the period of blow-out times of the waste gas; hence, if the pressure fluctuations increase too much, the height of a blowing lance 8 or the amount of the blowing lance is controlled to soften the blow. Namely, in this case, a lance elevator 20 is inputted with the analog signal for the results of the operation of the lance elevating rate of the circuit 18 and moves the lance 8 upward or downward by the required rate.
