Light Weight Clay Insulating Brick is made of high purity fire clay, by adding combustible, gas evolution method, or foam method.Lightweight fire brick is a kind of porous material with Al2O3 content 30-46%. Its refractoriness is 1580-1750 ℃, refractoriness under load is 1250-1450 ℃, with good thermal resistance and strong ability to resistant acid slag.The bulk density is 0.75-1.2g/cm3, crushing strength is 2.0-5.9MPa, thermal conductivity is 0.221-0.442W/(m.K) (1350℃)

► Application:
The light weight insulation brick can be in direct contact with the flame, to apply to the cracking furnace, hot stove, furnace, tunnel kiln, push board kiln, crucible furnace and electric furnace, electric kilns lined widely used in metallurgy, refractories, light industry, chemical industry, ceramics, glass, electronics and other industries. Dimensions of the product, the physical and chemical indicators, service life have reached or exceeded the level of similar products at domestic and abroad

► Characteristic:
♦ Low levels of iron and other impurities
♦High refractoriness,but can not contact with the flame directly
♦High porosity, low volume density, low thermal conductivity
♦Good heat insulating effect and energy-efficient
♦Good thermal shock stability.
♦Corrosion and erosion resistance
♦Long service life
