Production process:

Raw material mixing, molding, sintering, selection, packing, delivery.

1) Generally, High Alumina brick was molded by dry pressing.

2) By means of mixing the material uniformity in proportion and ageing mixture some time. Then, pour some powders into the mold and dry pressing.

3) After dry pressing, the adobe needs to be pushed in the drying kiln to stove or stay in the air to dry. This progress will need about 3-5 days.

4) After this progress, then push the adobe into the tunnel furnace or shuttle kiln to burn around 1300C. This progress will be need about 5-7 days.

5) After burning, the finished high alumina brick will be packed on pallet.
