Product description of chrome corundum brick
The main mineral composition of chrome corundum brick is α- Al2O3-Cr2O3 solid solution. The secondary mineral composition is a small amount of composite spinel (or without composite spinel), and the refractory bricks with chromium oxide content of 1%~30%.
Features of chrome corundum brick
- Wear-resisting
- High strength
- High temperature resistance
- Erosion resistance
- Good thermal shock
- High temperature creep resistance
Applications of chrome corundum brick
At present, the application of chrome corundum brick has been more widely used. One is made of metal chrome slag as the main raw material. This product is widely used in zinc smelting electric furnaces and volatile kilns. The chrome corundum brick has excellent thermal vibration stability and high temperature creep performance.
