Abstract

A gas-permeable block for metallurgical vessels consists of a shaped refractory body (1) penetrated by flow channels (7). To facilitate purging by melting or blowing of metallic infiltrations following an interruption in blasting, the channels (7) are steeply inclined to the longitudinal axis of the block, at least in the region adjacent to the gas outlet orifices. The angle ( alpha ) between the channels and the face (8) of the block provided with said orifices can vary between 15 DEG and 60 DEG , preferably between 20 DEG and 50 DEG . The flow channels (7) are preferably of spiral, undulating or zigzag construction.
