Abstract

PURPOSE: To remove an adhering matter of a converter tapping hole in the course of blowing, and to repair it safely and automatically, by installing a head member having both an excavating part and a finishing part, to the tip of a repairing material discharge pipe which is capable of rotating and moving back and forth freely.
CONSTITUTION: A repairing material discharge pipe 1 is installed to a truck 13 moving on a guide frame 11 through a sprocket 16 and chains 15, 16 by a motor 14, moves back and forth, and also rotates through a chain 24 by a motor 23. To the tip of said pipe 1, a head member 2 having an excavating part 3 and a finishing part 4 is tightly stuck by a supporting member 6. When repairing a tapping hole 5 of a converter 25, the head member 2 is positioned in almost the center of the steel feeding hole 5, and an adhering matter is removed by the excavating work. Subsequently, a repairing material and water are fed in through pipes 20, 22, respectively, at a position where a part of the finishing part 4 coincides with the inside surface of a furnace 25, and are rolled and applied on the inside wall of the tapping hole 5 by the finishing part 4.
