ABSTRACT:
In repairing a blast furnace wall by injecting and solidifying a refractory material on the inside wall of the furnace from outside the furnace, a line consisting of metallic coaxial lines or metallic parallel lines insulated from each other is embedded in the refractory material and the variation of the length of this line is measured through an electric signal to detect the remaining thickness of the injected and solidified refractory material in the furnace wall part.
By such detection, the damage of the repaired part of the blast furnace can be known with the lapse of time.
