The low thermal conductivity mullite brick is a new type of energy-saving refractory brick, which is composed of three layers of composite structure, working layer, thermal insulation layer and thermal insulation layer. It meets the requirements of wear resistance, corrosion resistance, peeling resistance and other properties, and also achieves the good effect of thermal insulation and energy conservation. It reduces the load of the furnace, reduces the heat load, reduces the heat energy loss, saves fuel consumption, and replaces the traditional masonry structure of heavy refractory bricks, This product is often used as the working lining of cement rotary kilns, lime kilns and other industrial kilns. The long-term service temperature is lower than 1400 ℃.
