High alumina fireclay Brick for Heating Furnace is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
This series of High Alumina fireclay Brick for Heating Furnace are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature.
Fireclay brick is shaped refractory product.It is made from flint clay clinker and binder , Through high heat sintering. The Al2O3 content range from 28% to 48%.The refractoriness range from 1580°C to 1750°C(SK-30.SK-32.SK-34.SK-35).
