The refractory materials used in cement industry mainly include refractory brick, refractory board, refractory fiber, refractory coating and refractory cement. These refractory materials have good high temperature resistance, erosion resistance and wear resistance, can be used for cement kiln, furnace tube, heating furnace, cooling machine, blast furnace and other equipment lining and heat insulation. They play an important role in cement production, ensuring the normal operation and long-term stability of production equipment. The following is a detailed introduction to the cement industry commonly used refractory materials.
1. Fire brick
The fire brick used in the cement industry is a kind of high temperature material with high fire resistance. It is mainly used in cement kilns, coolers, blast furnaces and other equipment lining, to protect the equipment from high temperature and corrosion damage. According to different use conditions and requirements, the types of firebrick are also different, common including high aluminum brick, magnesia aluminum spinel brick, magnesia chrome brick, magnesia iron spinel brick, silicon Mo wear-resistant brick, aluminum silicate brick, silicon carbide brick. These refractory bricks have excellent high temperature resistance, corrosion resistance and wear resistance, can operate stably in harsh environment for a long time, to ensure the normal operation of cement production equipment.
2, refractory board
refractory board is often used in cement kiln, clinker warehouse and other occasions, has good insulation and corrosion resistance.
3, refractory fiber
refractory fiber can be divided into ceramic fiber and glass fiber two kinds, mainly used for high temperature equipment heat insulation, such as cement kiln, furnace tube, heating furnace, etc.
4, refractory coating
refractory coating for refractory surface protection and repair, improve its wear resistance and corrosion resistance.
5, refractory cement
refractory cement is a special cement, mainly used for the production of cement kiln, blast furnace and other equipment lining, can withstand high temperature and chemical erosion.
These are commonly used refractory materials in the cement industry. These refractory materials are used to ensure the stable operation of production equipment under high temperature and harsh environment such as corrosion.
