Silica-Mullite-Red brick
Introduction:
Silica-Mullite-Red brick are developed according to the demanding requirements of cement rotary kiln for refractory materials. Its thermal shock resistance, thermal conductivity and refractoriness under load are better than ordinary silica-mullite bricks. When used in the transition zone and cooling zone of rotary kiln with a capacity of 3000~10000t/d, its excellent performance and service life are more superior than other products. It's an ideal alternative to spinel brick.
Advantages:
1.High refractoriness under load and excellent high temperature resistance;
2. High strength, abrasion resistance, peel off and erosion resistance;
3. Low thermal conductivity and good heat insulation effect;
4. Strong thermal shock resistance;
5. Moderate density, reduce load of the kiln cylinder.
Application:
Transition zone and cooling zone of the rotary kiln in cement industry.
