ABSTRACT:
An apparatus repairs a perforated brick employed in a wall of a metallurgical vessel and having an opening into which is to be fit a gas washing sink for introducing gas into molten metal within the metallurgical vessel, during which gas introduction the inner end of the gas washing sink and the perforated brick around such area become worn. The apparatus includes a casing having an outer contour corresponding to the outer contour of the gas washing sink and to be inserted into the worn opening of the perforated brick upon removal therefrom of the worn gas washing sink. The casing thus forms a template defining the contour of the opening to be repaired in the worn portion of the perforated brick. A repair material feed pipe extends through and is guided by the casing for supplying therethrough repair material for repairing the worn portion of the perforated brick. A spray head is attached to the inner end of the feed pipe for directing the repair material toward the worn portion of the perforated brick.
