ABSTRACT:
A safety-type gas washing sink for use in introducing gas through a metallurgical vessel and molten metal therein includes a refractory wearable brick portion defining a first sink end to be exposed to the molten metal and becoming worn during use, such wearable brick portion having therethrough gas flow paths for the passage of gas into the molten metal, and a refractory safety brick portion defining a second sink end to be directed away from the molten metal and through which the gas can be delivered to the gas flow paths in the wearable sink portion. The safety brick portion has a higher thermal conductivity than the wearable brick portion, and the gas flow paths continue into the safety brick portion. Thus, any molten metal that breaks through the wearable brick portion to the safety brick portion will be caused to solidify at the safety brick portion due to rapid dissipation of heat thereby.
