The characteristics and application of light weight refractory fire bricks

Users of refractory materials and the refractory industry itself belong to high-energy-consuming industries and are key targets for energy conservation and emission reduction. Energy-saving refractories are a kind of green refractories with great development prospect. The application of lightweight heat-insulating refractory bricks is an effective measure to realize energy saving in industrial kilns.
Lightweight refractory insulation bricks are commonly used in industrial kilns. Insulation bricks are mainly used in conjunction with heavy refractory bricks. High alumina bricks and heavy refractory bricks can directly contact the flame, but the load softening rate is in constant changes, the temperature of heavy refractory bricks will increase to 1300°C or higher as the temperature rises. If such a temperature directly touches the steel frame mechanism of the kiln, it will endanger the entire kiln, so In the process of building the kiln, the cooperation of light insulation bricks and heavy refractory bricks is essential. Laying a layer of light insulation bricks behind the heavy refractory bricks will not only effectively prevent the heat transfer but also reduce heat loss and save energy consumption.
Lightweight insulation bricks are selected mainly according to the using environment of the kiln, the temperature of the kiln, and the characteristics of kiln.Therefore, the construction of the kiln can not only be completed by using one type of refractory product, but requires multiple types. Only with the use of multiple refractory products can a high-efficiency, energy-saving, high-quality kiln be constructed.
