Low Bulk Density Insulation Refractory Alumina Brick For Thermal
The most competitive price,good quality,safty packing,prompt
delivery time,and excellent after-sales services.
Lighter weight,Low thermal conductivity,low impurities,high
insulating properties,high CCS and exact tolerance.
Characterized by low bulk density, maximum service temperature is
1350C., high cold crushing strength, size precision and hold the
most stable and lowest thermal conductivity of all insulating
refractory bricks at present.
The total weight of the furnace body and walls thickness can be
reduced effectively, thermal efficiency and working condition can
be improved, energy consumption can be lowered, and productivity
and significant economic results can be achieved.
High alumina lightweight insulating refractory brick 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.
By using the products widely in insulating layers of various
thermal equipments for example blast furnace, hot blast furnace,
coke oven and linings where no high temperatures melt corrosion
