Abstract
There are provided a shaft adapted for introduction into a tubular member made of refractory material and an expander provided on a leading edge of the shaft. The expander has both ends provided with a repairing material container and a seat plate. With the repairing material container having monolithic refractory material loaded therein confronted to a damaged portion in an inner wall of the tubular member, the expander is expanded by a driving motor to push the repairing material container toward the damaged portion while pushing the seat plate in contact with a wall surface opposite to the damaged portion in behind. Thus, the monolithic refractory material is filled and deposited in the damaged portion under remote control.
