Abstract
PURPOSE: To facilitate the next castable refractory filling operation in a short period of time by a method wherein a castable refractory filling hole is drilled in the damaged part of furnace wall and a castable refractory is filled, then, while it is semisolidified, a through-hole is opened, and an inert gas is injected through it.
CONSTITUTION: A desired number of castable refractory filling holes 4a are drilled, at proper positions, into the damaged part of furnace wall. The holes are drilled to the inner surface of refractory bricks 2 or the inner surface of the iron shell 1 so that the castable refractory can be filled smoothly. A castable refractory feeder 11 is connected to the holes 4a and then a castable refractory layer 5 is formed in the furnace. After filling, while the castable refractory is semisolidified, a hole 6 is opened through the castable refractory layer 5 to reach the furnace inside. An inert gas feeder pipe 7 is connected to the holes 4a, and, from the end of the through-hole 6, gas is projected to prevent the hole 6 from being blocked with foreign material. In this manner, the through-hole of the specified dimensions is secured until the next castable refractory filling operation.
