Low-conductive mullite refractory brick is a new type of cement kiln product. It is a composite structure composed of thermal insulation layer, thermal insulation layer and wear-resistant layer, achieving the effect of energy conservation and wear-resistance. The thermal insulation layer is made of high-grade refractory fiber material, the thermal insulation layer is made of lightweight refractory material, and the wear-resistant layer is made of mullite refractory material. The application of low thermal conductivity mullite refractory brick has replaced high alumina brick and silica mullite brick, improved the masonry structure of heavy refractory brick and light refractory brick, reduced the load of kiln body, reduced fuel consumption, shortened the masonry time, and effectively achieved the energy-saving effect
The low thermal conductivity mullite refractory brick has the properties of heat insulation, wear resistance, scouring resistance, corrosion resistance and peeling resistance. It is a composite structure product, achieving the effect of three product structures. Users have received good results in terms of construction strength, refractory consumption, energy conservation and environmental protection, kiln load, etc. Therefore, the products are favored by customers
