What are the uses of aluminum ore after crushing and processing

zkj/ Release time : 2023-06-20

Aluminum ore mainly has hard alumina monohydrate, soft alumina monohydrate and alumina trihydrate, all of which are ores for aluminum refining. We often come into contact with aluminum in our lives are generally aluminum pots, aluminum wire, aluminum windows, etc. In fact, metal aluminum is a very important industrial manufacturing raw materials, status and role second only to steel, because metal aluminum has good thermal conductivity, electrical conductivity, easy processing, etc., in addition to the above uses we know,bauxite by crusher processing, in construction, transportation, machinery, packaging, electrical appliances, petroleum, chemical It also has important roles in many fields such as:

(1) Aluminum refining industry. Used in national defense, aviation, automobile, electrical appliances, chemical industry, daily necessities, etc.

(2) Precision casting. Bauxite clinker is processed into fine powder and made into a casting mold for precision casting. Used in military, aerospace, communication, instrumentation, machinery and medical equipment sectors.

(3)Used in refractory products. The refractoriness of high alumina bauxite clinker is up to 1780℃, with strong chemical stability and good physical properties.

(4) Aluminosilicate refractory fiber. With the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and resistance to mechanical shock. Used in a variety of industries such as iron and steel, non-ferrous metallurgy, electronics, petroleum, chemical industry, astronautics, atomic energy and national defense. It is high alumina clinker into the melting temperature of about 2000 ~ 2200 ℃ high temperature electric arc furnace, by high temperature melting, high pressure high-speed air or steam blowing, cooling, it becomes a white "cotton" - aluminosilicate refractory fiber. It can be pressed into fiber blankets, plates or woven into cloth instead of smelting, chemical, glass and other industrial high-temperature furnace lining refractory bricks. Firefighters can use refractory fiber cloth made of clothing.

(5) The manufacture of bauxite cement, grinding materials, ceramic industry and chemical industry can be made of various compounds of aluminum.
