Refractory material is an important material to ensure the normal operation of cement rotary kiln, its performance and service life has a great influence on the kiln operation rate and the production quality, it is necessary to choose a suitable refractory material. Refractory materials used in cement industry mainly include:
1) Al2O3-SiO2 series products:
In addition to the transition and firing zones, Al2O3-SiO2 series products can be applied to the entire precalciner kiln firing system. Al2O3-SiO2 series refractory bricks mainly include alkali-resistant series bricks, high-aluminum (anti-stripping) series bricks, and silicon mullite series bricks.
2) Alkali Resistant bricks
The fired zone lining of rotary kiln is the most severe part of the lining, only alkali resistant bricks can meet the use requirements under this working condition.
3）Insulation Materials
In general, the mostly used insulation materials for cement kiln is calcium silicon board. At the same time, the usage amount of light weight insulation castables, insulation bricks, ceramic fiber products also increase.
