High Alumina Advantages:High temperature resistance (1700℃+), strong thermal stability

High density, compression and wear resistant

Excellent thermal insulation performance

Good chemical stability, corrosion resistant Long service life, high cost performance

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).

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.
