PURPOSE:To control the yield of converter operations according to the state of slopping by detecting the slopping in the converter and the fluctuations in the temps. on the surfaces in the upper and lower parts of the converter according to the drop of slopping slag. CONSTITUTION:The surface temp. in an upper part A including the converter port 16 of a converter body 10 is detected with a radiation thermometer 12 for the upper part, and from the rise of said surface temp. and the detection signal V indicating the curve for the temp. drop by the radiation of the sensible heat of slopping slag, the generation of slopping is detected by a detector 14. A radiation thermometer 18 for the lower part is further provided for the lower part B of the body 10, and the generation of slopping and the amt. of the slopping are detected in the detector 14 from the rise of the surface temp. in the part A, the peak value thereof, the presence or absence of the cooling curve in succession to said peak value by the cooling of the slopping slag, the presence or absence of the rise of the surface temp. in the part B by the fall of the slopping slag and the peak value thereof. |
