Fused cast alumina bricks are divided into fused cast alumina bricks α- Alumina brick, fused cast β- Alumina brick and fused cast α-β Alumina brick, once applied in glass furnace and electrolytic cell of nonferrous metal smelting furnace, has received excellent application effect. The main reason is that the fused alumina brick has the following excellent characteristics, which reflects the extremely significant service life.
The fused cast alumina brick has few impurities, compact structure, extremely low apparent porosity, very high strength and excellent thermal shock resistance. Therefore, the product has excellent high-temperature resistance, scouring resistance, corrosion resistance and stability under high temperature. In particular, the glass phase content of the product is small, no bubble and other foreign matters are generated, and there is no pollution to the glass liquid. It is more suitable for the application of glass furnace, It has better effect than fused zirconia corundum brick. It is mainly used in the tank wall, bottom laying, flow channel, hanging wall and other parts of glass tank furnace. It also has good effect in crucible furnace and electrolytic cell for non-ferrous metal smelting.
