Abstract (en)
[origin: EP0458040A2] In a gas-bubbling assembly on a metallurgical vessel, a perforated brick (2) receiving a bubble brick (4) is inserted into a brick-lining (1) of the vessel bottom. To simplify the structure and to delay wear, the perforated brick (2) protrudes beyond the bubble brick (4) and the brick-lining (1). On the gas outlet side (15) of the bubble brick (4), the perforated brick (2) is gas-permeable. <IMAGE>
