bauxite

Product use

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

⑵ Precision casting. The bauxite clinker is processed into fine powder and made into casting mold. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment sectors.

It is used for refractory products. High bauxite clinker refractoriness up to 1780℃, strong chemical stability, good physical properties.

(4) 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 vibration resistance. Used in iron and steel, non-ferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense and other industries. It is the high aluminum clinker into the melting temperature of about 2000 ~ 2200℃ in the high temperature arc furnace, after high temperature melting, high pressure and high speed air or steam spray, cooling, became 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 clothes out of refractory fabric.

⑸ magnesia and bauxite clinker as raw materials, add appropriate binder, used for pouring the whole barrel lining of the steel drum is very good.

The manufacture of bauxite cement, grinding materials, ceramic industry and chemical industry can make a variety of aluminum compounds.
