1、 Production process
Raw material preparation: Using high-purity industrial alumina as the main raw material, adding a small amount of additives (such as silicon micro powder, calcium oxide) to enhance performance.
High temperature melting: Melting raw materials in an electric arc furnace or resistance furnace at a temperature above 2000 ℃ to form white corundum melt blocks.
Cooling crystallization: The melt is slowly cooled and crystallized in the furnace, and the cooling rate and temperature gradient are controlled to optimize the crystallization quality.
Crushing and Grinding: After the crystal is initially crushed by a crusher, it is further ground into fine powder of different particle sizes through a ball mill or air flow mill.
Screening and packaging: After screening, obtain fine powder with target particle size (such as 180-0 mesh, 220-0 mesh, 240-0 mesh, 325-0 mesh, etc.), and package according to demand.
2、 Performance characteristics
High hardness and wear resistance: The Mohs hardness is close to 9, second only to diamond, making it suitable for processing high hardness materials.
Good self sharpening: New cutting edges are automatically formed during the grinding process, maintaining efficient grinding.
Strong chemical stability: resistant to acid and alkali corrosion, suitable for complex chemical environments.
High temperature resistance: Excellent thermal stability, able to maintain stable performance at high temperatures.
Uniform particle size: The particle distribution is concentrated, and the grinding surface quality is high.
Environmental friendliness: There are no harmful substance emissions during the production process, and the products are free from radioactive pollution.
