Use of a heavy clay, refractory product, in the form of ceramically fired or unfired shaped and / or pressed monolithic products manufactured in a ceramic factory or manufactured by the user, used in industrial firing or smelting or other fired industrial aggregates, e.g. B. be used in a large-volume industrial furnace for fireproof lining thereof, - From a granular refractory material or a mixture of refractory granular materials, gekennzeich net by an open porosity of the product between 23 and 45% by volume, and - A grain structure of the granular refractory material or the mixture of refractory granular materials, the average grain content with particle sizes between 0.1 and 0.5 mm 15 to 55 wt .-%, with the remainder of the grain structure flour grain fraction with particle sizes up to 0.1 mm and / or coarse grain fraction with grain sizes over 0.5 mm, in industrial firing or melting or in other fired industrial aggregates, eg. B. in a large-volume industrial furnace, the refractory, fire-side lining thereof. |
