Chrome corundum fire brick introduction
Chrome corundum fire brick for furnace is a refractory product containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form continuous solid solution, so the high temperature performance of chrome corundum fire brick products is better than that of pure corundum products.
Chrome corundum fire brick for furnace feature
- Wear resistance
- High strength
- High temperature resistance
- Erosion resistance
- Good thermal shock
- Resistance to high temperature creep

Chrome corundum fire brick application
At present, the application of chrome corundum fire brick has been more widely. One kind of chrome corundum fire brick is made of chromium slag as the main raw material, which is widely used in zinc smelting electric furnace and evaporation kiln. Chrome corundum fire brick has excellent thermal vibration stability and high temperature creep performance.
