Heat insulation fire proof refractory brick Lightweight clay brick is made of high purity fire clay, by adding combustible, gas evolution method, or foam method.Lightweight clay brick is a kind of porous material with Al2O3 content 30-46%. Its refractoriness is 1580-1750 °C, refractoriness under load is 1250-1450 °C, 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°C)
Feature:
1.Low levels of iron and other impurities
2.High refractoriness,but can not contact with the flame directly
3.High porosity, low volume density, low thermal conductivity
4.Good heat insulating effect and energy-efficient
5.Good thermal shock stability.
6.Corrosion and erosion resistance
7.Long service life
