Description

Refractory lightweight high alumina thermal insulating fire brick

Product Description

High alumina lightweight insulating refractory 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 30% ~ 46% 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.
