ABSTRACT:
A gas-transmitting wall element for a metallurgical vessel having a refractory lining is described which is subject to low wear, is reproducible and makes unnecessary continuous blowing of gas through it. The element has an outer sheet metal box, open at one end, and a refractory filling in the box comprising at least one brick spaced from the closed end of the box, into which a gas inlet opens. The brick contacts the metal sidewalls of the box and has grooves to allow the gas to pass to the open end of the box.
