Light Weight Clay Insulation brick is made of fireclay materials and the content of alumina in it is 35%-48%. It is manufactured by grinding and mixing the crushed combined clay and levigated clinker, confecting with particle clinker into medium dry pug, high pressure molding, and firing under the temperature of 1200℃-1400℃.
Performance Characters:
1.high porosity.
2.small volume density.
3.good insulation effect.
4.high mechanical intensity.
5.small thermal conductivity.
Application:
Light Weight Refractory Clay Bricks is of low price, but of good thermal vibration stability and thermal insulation, mainly used in thermal boiler, glass kiln, cement kiln, fertilizer gas furnace, blast furnace, hot-blast stove, coking furnace, electric furnace, casting, etc.
