Silica mullite brick

Silica-mullite brick is made of high quality mullite and silicon carbide, with appropriate amount of grinding aid and zircon sand as auxiliary materials.

Advantages

Excellent resistance to erosion and wear, excellent resistance to erosion and wear resistance to stripping and alkali erosion, excellent cost performance.

Application

The brick surface temperature of the cement rotary kiln transition zone is about 1400°C, and the temperature of the pre-zone and cooling zone is lower than that of the transition zone. Even if the firing zone is protected by the kiln skin, the brick surface temperature is not high. The load softening temperature of the silicon Mo brick is above 1500°C, especially the product structure is dense, composed of high hardness minerals, corundum, silicon carbide and mullite. Excellent wear resistance, it is the ideal brick for the transition zone. The compressive strength and softening temperature of load are obviously higher than those of high-alumina brick resisting spalling, and its thermal shock stability, corrosion resistance, good wear resistance and low thermal conductivity are just the requirements of the post-transition zone process characteristics, and its service life is 1.5~2 times that of anti-spalling brick. Good wear resistance is more suitable for cooling belt, the service life can reach more than two years, is 3~5 times of high aluminum brick life. Now according to the use conditions of different sections of rotary kiln, different grades of silicon Mo brick with different properties have been applied.
