Product Description

 Bauxite is mainly composed of alumina, it is a hydrated alumina with impurities, which is a kind of earthy mineral, it is White or off-white. It is brownish yellow or reddish due to include iron . Its density is 3.45g/cm3, hardness 1 ~ 3 . It is opacity and brittle. It is very hard to dissolve in water, but it is soluble in sulfuric acid and sodium hydroxide solution. It is mainly be used for aluminum smelting and refractory .

 

Our company mainly supply bauxite clinker.   Bauxite clinker is also named as high aluminum clinker. The Various high alumina brick is produced by bauxite clinker and it is the refractory or anticorrosive materials in metallurgical industry and other industries, especially in the top of electric furnace, and blast furnace and hot blast stove, its refractory effect is very remarkable, and its performance is superior to ordinary clay refractory brick.

Product Uses

 

(1) Refining aluminum industry.

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

2) 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.

3) Refractory products.

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

4) Aluminosilicate refractory fiber.

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

Used in steel, non-ferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, national defense and other industries.

5)Using magnesia and bauxite clinker as raw materials, and adding appropriate binder, It have the good effect used for casting integral barrel lining of ladle

6) It can be used for producing bauxite cement, abrasive materials, a variety of aluminum compounds in  ceramic industry, chemical industry.
