1.High alumina Insulating brick Description

Light weight High alumina Insulating brick is made by clay clinker or light clinker and plastic clay as the main raw material, usually fuel production, but also can send or chemical foaming method porous structure. Common light chamotte bulk density of 0.75 ~ 1.2g / cm3. It refers to containing AL2O3 more than 48%  of lightweight refractory products, mainly for industrial kilns does not melt and no erosion of the contact action of gas insulation layer material, the using temperature is 1200 ~ 1400 ° C.

 

  1. High alumina Insulating brick Feature

1.Excellent strength at ambient and elevated temperatures.

2.High compressive strength.

3.Very low levels of iron and other impurities.

4.Lightweight and energy-efficient.

5.Lower heat storage than denser refractory.

6.Heats quickly and economically to operating temperature.
