Introduction of high alumina brick:
The high alumina bricks comprise of a blend of alumina and ferrous content and their apparent porosity is 15 to 23%. High alumina brick has the feature of high refractoriness and can sustain themselves easily even in high temperature.
High alumina brick is widely used for widely used in blast furnaces, hot bast stove,steel ladle lining, reheating furnace, cement kiln, tunnel kiln,boiler, coke oven, carbon furnace,glass kiln , steel smelting furnace and various kiln lining and thermotechnical equipment, etc.

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.
