Character:
Light heat insulation refractory is of high purity, good mechanical performance, low conductivity factor, direct contact with flame, good scaling and ht resistances, can be used both as heat insulating lining of ht industrial kilns and as working liner of other ht industrial kilns so as to decrease weight of lining up block and to save energy.
Application:
Petrochemical Trade: Carbon black furnace , gasification furnace, gas-making furnace , ethene pyrolyzer , one stage converter, hydrogen furnace , etc.
Ceramics Trade: Tunnel kiln, bucket kiln, roll kiln, shuttle kiln, top-hat kiln, mesh-belt tunnel kiln , etc.

Strong Corundum-mullite Serial Products are of high purity, high content of principal crystalline phase (corundum or mullite) , HT-, washing-and corrosion-resistances, hence good application effect in HT kilns in petrochemical, building material, etc. trades.
