Abstract

PURPOSE:To directly and quantitatively predict slopping in a converter without any delay by observing brightness of a steel tapping hole in the converter with a furnace condition displaying device, further finding brightness value, etc., of the steel tapping hole from an image pickup device and predicting development of the slopping by this value. CONSTITUTION:The picture at the steel tapping hole 3 and the neighborhood in the converter wit the image pickup device 10 is shown in the furnace condition displaying device 13. On the other hand, the arithmetic unit 12 analyzes the signal from a picture processor 11 and finds the brightness value of the steel tapping hole 3 or its variation at the lapse of time, and they are quantitatively displayed with the alarming device 14. Then, when their values come in the range which development of the slopping is possible, the device 14 gives the alarm on the display or sound. Further, the above range can be statistically found beforehand with an observing device 20 for furnace condition in the converter at each blowing condition.
