Abstract

PURPOSE:To prolong the life of the repaired layer, by forming the repaired layer at the damaged part with the refractory repairing material in a state at which a part of slag is remaining in the converter, then coating the repaired layer with the slag and solidifying the slag, at the repairs of the locally damaged parts on the furnace wall of the converfer.
