Chrome Corundum Brick

Chrome Corundum Brick Introduce
 
Chrome Corundum Bricks is produced with high quality of sintered corundum, synthetic mullite and chromium oxide as raw refractory material and processed under high temperature and high pressure. Firebricks chrome corundum have high bulk density, high compressive strength, good thermal shock resistance, good corrosion resistance to acid and alkali. Chrome corundum refractory bricks are not affected by H2, CO gase.

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.
 
Features of Chrome Corundum Bricks
 
1. High bulk density.

2. High softenning temperature under load.

3. Good wear resistance.

4. Good thermal shock resistance.
