bauxite

(1) Aluminum smelting industry. Used in national defense, aviation, automobile, electrical appliances, chemical industry, daily necessities and so on.

Precision casting. Bauxite clinker is processed into fine powder and made into casting mold after precision casting. Used in military, aerospace, communications, instrumentation, machinery and medical equipment departments.

⑶ used for refractory products. High bauxite clinker refractories up to 1780℃, strong chemical stability, good physical properties.

Aluminum silicate refractory fiber. It has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical shock resistance. Used in iron and steel, non-ferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense and other industries. It is to put the high aluminum clinker into the melting temperature of about 2000~2200℃ high temperature arc furnace, after high temperature melting, high pressure high speed air or steam blowing, cooling, become white "cotton "- aluminum silicate refractory fiber. It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical, glass and other industrial high temperature furnace lining firebrick. Firemen can make clothing from fire-resistant fibre cloth.

Using magnesia and bauxite clinker as raw material and adding appropriate binder, it is used for casting shenggang drum with excellent overall lining effect.

⑹ alumina cement manufacturing, grinding materials, ceramic industry and chemical industry can make various compounds aluminum.
