The manufacturing process of high alumina bricks:
1. Raw Material Selection: High-alumina bauxite (Al2O3 content ≥48%) is selected as the main material, combined with clay, silica, and other auxiliary materials, and crushed to a uniform particle size.
2. Batching and Mixing: Materials are batched according to the specified ratio, water or binder is added, and mechanically stirred until the material is uniformly plastic.
3. Molding: Brick blanks are made by pressing (manual/hydraulic press) or extrusion molding (controlling density and dimensional accuracy).
3. Molding: Brick blanks are made by pressing (manual/hydraulic press) or extrusion molding (controlling density and dimensional accuracy).
4. Drying: Natural drying or oven drying (temperature 80-120℃) is used to remove moisture from the brick blanks (to prevent cracking during firing).
5. Firing: The bricks are pushed into a tunnel kiln/downdraft kiln and sintered at a high temperature of 1500-1700℃ to complete crystal transformation and densification .
6. Cooling and Inspection: After natural cooling, the dimensions, strength, high-temperature resistance, and other indicators are tested. Qualified bricks are then stored in the warehouse.
Where are high alumina bricks generally used?
1. Iron and Steel Industry 2. Non-Ferrous Metallurgy Industry
3. Building Materials Industry (Cement, Glass, Ceramics)
4. Chemical and Petrochemical Industry
