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.

Semi-silica brick refers to an aluminum-silicon refractory product with a SiO2 content of greater than 65% and an Al2O3 content of 15% to 30%. They generally use clay containing quartz impurities or native kaolin refractory clay or tailings and pyroph...
The Al2O3 content of anchor bricks is above 55%, and some users require that the alumina content reach 75%, and the load softening temperature of 75% bricks reaches 1550C. However, in actual use, anchor bricks with high aluminum content cannot be enough. The key is Flexibility is the most important t...
