In a vessel for producing or refining molten metal, excessive heat is generated on top of the molten metal, resulting in excessive wear of the refractory lining of the vessel. The invention provides a plurality of channels constructed within the refractory lining and means for circulating gaseous material through each channel to cool the lining to reduce wear induced by heat. Spherical beads of refractory material can be packed in the plurality of channels to evenly distribute the flow of gaseous material throughout the channels. The invention is applicable to any refractory lining wherein heat-induced wear is a problem.
