Lightweight refractory fire bricks are fired after adding certain special substances in the manufacture of refractory bricks. Its porosity is twice as high as that of ordinary refractory bricks, its bulk density is 0.5 to 7 times smaller than that of refractory bricks, and its thermal conductivity is small, so it can be used as a furnace insulation layer or lining to reduce heat loss; The furnace wall heat storage and heat dissipation loss can be reduced by 80%.
Advantage of light weight refractory fire brick
1. Economy: It can reduce the basic cost, reduce the cross-section of the structure, and save required steel and concrete, which can significantly save the overall cost of the furnace building. The design and use of lightweight bricks can reduce the cost by more than 5% compared with the use of solid clay bricks.
2. Workability: Lightweight refractory fire bricks have excellent machinability and are easy to construct. Because of their large size and light weight, they can reduce labor intensity, improve construction efficiency and shorten construction periods.
