Abstract
An apparatus for supplying gas through the wall of a metallurgical container includes a fireproof refractory brick having a free inner end adapted to be exposed to the interior of the metallurgical container, an outer end opposite the inner end and a peripheral area extending between the outer and inner ends. A metal cover surrounds the peripheral area. A gas connection supplies gas to the outer end of the brick. Gas passages extend from the outer end of the brick to the inner end of the brick to supply gas to the interior of the metallurgical container. These gas passages are in the form of at least one arrangement of a fireproof ceramic fiber material extending between the outer and inner ends of the brick.
