Introduction
NATI Insulating Firebrick own light weight, with mini-pore equally distributed, compared with common firebricks, so NATI IFB keep furnace wall low heat loss and save the cost of fuels, NATI IFB also means lower heat storage, heating and cooling more fast, easy for discontinuous operation. NATI IFB is suitable among the range 900℃~1650℃.
Characteristics
*Low thermal conductivity
*Low impurity content
*High strength
*Excellent resistance to thermal shock
*Resistance to erosion
*High accuracy of dimension
Typical Application
*Lining for hot-surface of industrial furnaces, such as carbon furnace, cracking heater, heating furnace for oil refining, annealing furnace, roller kiln, tunnel kilns etc
*Back-up lining of industrial furnaces, such as glass tank kiln
*Deoxidizing atmosphere furnace
