Description of High-Temp Slag Erosion Resistance Chrome Corundum Brick
Chrome corundum brick uses a-Al2O3 as raw material, adding appropriate amount of chromium oxide powder, chrome corundum powder and additives, etc.,after molding, it is fired at a high temperature of 1700 ℃ to form chrome corundum bricks.
Fearures of Chrome Corundum Refractory Brick
1.Excellent thermal shock stability
2.Small high temperature creep value
3.Good wear-resistance,slag-resistance and alkali corrosion resistance.
4.High-purity raw material, barely no pollution.
5.High Bulk Density
Shapes and sizes: there are great variety of formats and shapes which are available for different forming and special machine processes.
Application of Chrome Corundum Bricks:
Chrome corundum refractory bricks are mainly used in the refractory material linings in decomposing furnaces for petroleum and chemical industry, as well as the chemical fertilizer industry. Fireproof chrome corundum bricks are also used as high temperature kiln linings and furnitures in metallurgical industry.
