Product Description

1.Description

High alumina insulating fire brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. The Al2O3 content is 50-85%.

2.Feature

1.Low levels of iron and other impurities

2.High mechanical intensity

3.High refractoriness, can contact with the flame directly, suitable for various atmosphere

4.High porosity, low volume density, low thermal conductivity

5.Good heat insulating performance and energy-efficient

6.Low creep rare at high temperature,good thermal shock stability

7.Chemical corrosion resistance

8.Long service life
