Fused cast alumina block is produced by special electric melting furnace which in the temperature is nearlly
2000°C, the major raw materials is high purity alumina.
Fused cast alumina block also name fused α-β corundum block, α-β corundum is formed when α corundum & β corundum inter-combine in the srystallization stage, the compact structure is forme also.fused cast alumina block has excellet endurance to strong alkali.Characters for the free contamination to the glass furnace, fused cast alumina block is widely used for sideway of the working end, bottom paving, forehearths and crowns in the special glass furnace.
Fused cast alumina α-corundum block is another type of fused cast alumina block, whcih the major crystal phase is α-corundum, the percent is more than 90%. Fused cast alumina α-corundum block widely used for cooling pool and superstructure of glass furnace, you also can find it in the non-ferrous matel melting fuirnace high temperature tunnel kiln.
Fused cast alumina β corundum block is another type of the fused cast alumina block, the major crystal phase is β corundum, the percent is more than 95%. Fused cast alumina β corundum block is widely use for upper part of the structure where less scattered glass powder exists.
