Insulating Refractory Fire Resistant High Alumina Light Weight Fire Clay Insulation Brick
For various industrial kilns & furnaces,Light weight high alumina brick can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.
Description
In order to improve product quality and economic benefits, technical improvement and innovation must be carried out. After in-depth analysis and research, we decided to apply the new technology to our High Alumina Insulating Brick, Cordierite Mullite Plate, Refractory Bricks. Market competition, in the final analysis, is the competition of talents. How to improve the quality of employees and strengthen their core competitiveness is an urgent problem to be solved. We are your best choice.
| 1.High alumina Insulating brick Description |
Lightweight 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.
