Ceramic Factory Kiln Gas Furnace Steel Factory Furnace Alumina Hollow Ball Insulating Refractory Brick

DESCRIPTIONS
The One alumina hollow ballinsulating refractory brick is made of alumina hollow balls,fused white corundum and composite fine powder, which are formed by hydraulic vibration and sintered at high temperature. possess large quantity of closed pore,have the characters of light weight & high temperature resistance,low thermal conductivity,high strength,tiny reheating linear change,good thermal shock resistance, etc.Alumina hollow ball insulating refractory brick can greatly improved the furnace heat efficiency, shorten production circle,lighten furnace weight and realize
energy saving.

APPLICATIONS
Shuttle kiln,tunnel kin,pushed slab kiln,carbon black reactor,reformer,brighten stainless steel annealing furnace, powder metallurgy furnaces, battery material sinter furnace,etc.
