METHOD FOR REPAIRING REFRACTORY WALL FOR MOLTEN METAL CONTAINER

摘要

PROBLEM TO BE SOLVED: To enable the damage position of a refractory wall to be efficiently repaired. SOLUTION: A method for repairing the refractory wall for a molten metal container comprises the steps of relaying the refractory bricks 5 of an upper part than refractory bricks 5A disposed at a boundary to a molten steel part T of the refractory bricks of a slag line S by retaining the bricks 5A by one or more steps when the residual thickness of the bricks 5A is 2/3 or more of an original size in the case of repairing the damaged site of the lined refractory wall of the molten metal container, and spraying a wet spraying 6 material to the residual damaged site by a spraying method to repair the damaged site.
