Description

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

Application of Chrome Corundum Bricks
 
Corundum Bricks are mainly used in the linings in decomposing furnaces for petroleum and chemical industry, as well as the chemical fertilizer industry. They are also used as high temperature kiln linings and furnitures in metallurgical industry.
 
Chrome corundum bricks have been widely used. Mainly used for carbon black furnace, steel rolling furnace sliding table, steel platform. It has good thermal stability and high temperature creep properties.
 
One is chrome corundum brick made of metal chromium slag as the main raw material. This product is widely used in zinc smelting electric furnaces and volatilization kilns. Chrome corundum bricks have excellent thermal vibration stability and high temperature creep properties. At the same time, it meets the requirements of the country's circular economy.
 
Another type of refractory brick called aluminum chromium spinel bricks. It is widely used in copper smelting, breaking the monopoly of magnesia-chrome bricks in one fell swoop.
 
Features of Chrome Corundum Bricks
 
1. High Bulk Density
2. High softenning temperature under load
3. Good wear resistance
4. Good thermal shock resistance
