Abstract (en)

[origin: EP0325709A2] In a gas-bubble brick of refractory ceramic material, the visual detectability of a worn state is improved. The detectability should be independent of the material of the gas-bubble brick. For this purpose, a gas-permeable distance space 3, which has a different geometrical shape in the direction of wear, extends in the gas-bubble brick. As a result, a different pattern corresponding to the state of wear is visible on the surface of the gas-bubble brick when gas flows through the distance space 3. <IMAGE>
