Chrome Corundum Composite Brick
The chrome-corundum composite brick produced by our company combines light and heavy bricks together. When the heavy refractory brick wears 120mm, the whole refractory brick still has 180mm (generally designed according to 300mm), and it can continue to be used for 3-5 months. Greatly improved the service life of refractory bricks. Originally, the inner lining of the hazardous waste rotary kiln was designed as a two-story masonry construction. The inner insulation layer used lightweight clay bricks, and the refractory layer used heavy refractory bricks. When the heavy refractory bricks are worn

Chrome Corundum Composite Brick Details
The chrome-corundum composite brick produced by our company combines light and heavy bricks together. When the heavy refractory brick wears 120mm, the whole refractory brick still has 180mm (generally designed according to 300mm), and it can continue to be used for 3-5 months. Greatly improved the service life of refractory bricks.
Originally, the inner lining of the hazardous waste rotary kiln was designed as a two-story masonry construction. The inner insulation layer used lightweight clay bricks, and the refractory layer used heavy refractory bricks. When the heavy refractory bricks are worn to 120mm, they cannot be used anymore, and the bricks are easy to fall off.
Advantage
The chrome-corundum composite brick has the characteristics of wear resistance, erosion resistance, high temperature resistance, good thermal shock stability and high temperature creep.
At the same time, it also has the properties of anti-iron oxide, sodium oxide and acid corrosion, low thermal conductivity and so on.
Application
The chrome-corundum composite brick widely used in high-temperature thermal equipment such as the high-temperature lining of the rotary kiln in the waste incineration production line.
