The production process of high temperature calcined brown fused alumina differs from that of ordinary brown fused alumina in that the latter undergoes a secondary high-temperature calcination at a temperature of approximately 1400 ℃. The calcined brown fused alumina exhibits superior characteristics compared to ordinary brown fused alumina.
The production of high temperature calcined brown fused alumina is an emerging industry with strong growth momentum and broad market prospects.
Compared with ordinary abrasives, the performance advantages of high temperature calcined brown fused alumina are mainly reflected in the following five aspects:
Increased magnetic induction
Weak magnetism is converted into strong magnetism, allowing for the effective removal of magnetic materials.
Improved hydrophilicity
Hydrophilicity is increased by 2-3 times.
Improved recovery
High temperatures can effectively repair cracks generated in abrasive materials during heavy-duty crushing, facilitating the healing of crystal fractures.
Increased bonding strength
The high-temperature sintering process vaporizes impurities on the abrasive surface, significantly increasing the specific surface area of the particles, resulting in a stronger bond between the high temperature calcined brown fused alumina and the fabric backing.
Improved durability
High temperature calcined brown fused alumina has a durability increase of over 40% compared to ordinary brown fused alumina.
