Alumina silicon carbide brick
Alumina silicon carbide brick is made of special grade high alumina bauxite, silicon carbide, mullite, etc. as the main raw material through special sintering process. It has the characteristics of high strength, wear resistance, small thermal conductivity and excellent heat vibration stability. In the process of use, it continuously forms a protective layer to reduce the knotted circle. Aluminous silicon carbide brick is mainly used in cement kiln rotary kiln, the front transition zone, the rear transition zone, but also for the use of temperature, wear resistance and thermal shock temperature comprehensive requirements of the higher kiln. Such as particle steel rotary kiln, magnesite incinerator, sintered mullite rotary kiln, etc.
Alumina silicon carbide andalusite brick
Alumina silicon carbide andalusite brick is based on the special grade bauxite, silicon carbide, mullite and added andalusite.
Main characteristics: high strength, strong erosion resistance, wear resistance, excellent thermal shock stability, and in the process of use and can continuously form a protective layer to reduce the knotted circle. Alumina silicon carbide andalusite brick can cover all process belts except the firing belt. Alumina silicon carbide andalusite brick brick is not only used in cement kilns, but also suitable for kilns with higher requirements on operating temperature, wear resistance and thermal shock temperature, such as particle steel rotary kiln, magnesite incinerator, sintered mullite rotary kiln, etc.
Composite aluminum silicon carbide brick
Composite aluminum silicon carbide brick is directly compounded with both heavy and light materials, and is divided into two parts: working layer and heat insulation layer, with a wavy sawtooth shape at the junction. The working layer is made of aluminum silicon carbide brick, and the heat insulation layer is made of light mullite brick, which ensures the high strength while the shrinkage and expansion rate in the high temperature sintering process is close to that of the working layer. The main feature of this product is low thermal conductivity, verified by users, can reduce the barrel temperature of about 30 ℃, energy saving and consumption reduction effect is very obvious.
