insulation firebrick

Short Description:

The density of insulation firebrick is 0.60~1.25g/cm3, and the working temperature is 900°C to 1600°C. Insulation firebrick can reduce the cost of the foundation, reduce the cross-section of the frame, and save reinforced concrete can significantly save the comprehensive cost of the building. Compared with solid clay bricks, the overall cost of using lightweight bricks can be reduced by more than 5%. Lightweight bricks have good work ability and are easy to construct.

Features

Lower thermal conductivity / Lower bulk density

Light weight / Lower creep rate in high temp

Good thermal shock resistance performance

Application

Insulation firebrick can be used for the back insulation of hot surface refractory lining or other refractory materials; it can also be used as refractory lining or insulation material for petroleum and chemical kilns
