Introduction to bauxite clinker


Bauxite clinker is also named as high aluminum  clinker. Various bauxite high alumina brick is a kind of  refractory or anticorrosive materials, which is widely used in the metallurgical industry and other industries. Especially in the top of electric furnace, blast furnace and hot blast stove, the refractory effect is very remarkable, and the performance is superior to ordinary clay refractory brick.

APPLICATION

Refining aluminum industry

Bauxite clinker is used in national defense, aviation, automobile, electrical appliances, chemical         industry, daily necessities etc.

Precision casting

Bauxite clinker can be processed into fine powder and made into investment casting,which is used in military project,spaceflight, telecommunications, instrumentation, machinery and medical device       department.

Refractory products

The refractoriness of high bauxite clinker is up to 1780℃. It has strong chemical stability and good   physical properties.

Aluminosilicate refractory fiber

1) It has the advantages of light weight, high temperature resistance, good thermal stability,  low        thermal conductivity, small heat capacity and mechanical vibration resistance.

2) It is used in steel, non-ferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic     energy, national defense and other industries.

3) By putting high-alumina clinker into high-temperature electric arc furnace with melting temperature of about 2000-2200 C, and  melting at high temperature, and blowing and cooling by high-pressure   and high-speed air or steam ,white cotton is formed, which is called aluminosilicate refractory fiber.

4) It can be compressed into fiber blanket, board, or woven into cloth instead of the firebrick of high-temperature furnace lining in metallurgy, chemical, glass and other industry.

5) Firefighters can use refractory fiber cloth to make clothes.

Other applications

1) Using magnesia and bauxite clinker as raw materials, and adding appropriate binder, the effect of casting integral barrel lining of ladle is very good.

2) It is used to produce bauxite cement, abrasive materials, ceramic industry, chemical industry, as   well as a variety of aluminum compounds
