Insulating Fire Furnace Bricks , Burned Micro porous Alumina carbon Bricks Al2O3 55%
Alumina-carbon brick used superfine calcined bauxite and sintered or fused corundum sand as main raw material and added composite graphite powder has received very good use effect of iron powder erosion resistance, carbon powder erosion resistance and atmosphere scour erosion resistance.
Feature:
1.High hardness,high mechanical strength,
2.High temperature of refractoriness under load,
3.Good thermal shock resistance and slag resistance,
4.Strong corrosion resistance,
5.Strong resistance against alkaline substances,
6.High thermal conductivity,low thermal expansion,
7.Good thermal shock resistance.
Application:
Alumina-carbon brick is widely used in blast furnace,hot metal ladle,sliding gate brick,steel ladle,tundish,ladle shroud,submerged nozzle,monoblock stopper for continuous casting of blooms.
