Abstract in another language

In the non-ferrous metals industry, particularly in copper and lead smelting furnaces, the working lining frequently comprising magnesia-chromite bricks is exposed to several stresses. These can be classified as chemical, thermal, and mechanical stresses occurring as a single wear factor or in combination. The chemical factors include corrosion caused by slag and/or gaseous SO2 diffusion, redox effects, and hydration. In most of the non-ferrous metallurgical processes the chemothermal load resulting from Fe-silicatic slags of a fayalithic type is a common wear mechanism of magnesia-chromite bricks. Nevertheless, atypical massive SiO2-supply caused by changes in the processing and/or the uncontrolled addition of silica sand results in the substantial formation of forsterite, which due to the associated volume expansion causes “forsterite bursting”. Whilst such a wear phenomenon is seldom experienced in non-ferrous applications, it is quite typical for regenerator chambers in the glass industry in the case of extreme SiO2 supply (“carry-over”).
