Bauxite rotary kiln kiln calcination wear-resistant coating Industrial ceramic smelting
Product name:bauxite
Specification: 320#
1. Product use
( 1 ) Aluminum industry. It is used for national defense, aviation, automobile, electrical appliances, chemical industry, daily necessities and so on.
( 2 ) Precision casting. The bauxite clinker is processed into fine powder for precision casting after casting mold. For military, aerospace, communications, instrumentation, machinery and medical equipment sector.
( 3 ) Used for refractory products.
( 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. It is used in 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 °C high temperature electric arc furnace, through high temperature melting, high pressure and high speed air or steam injection, cooling, became white ' cotton ' - aluminum silicate refractory fiber. It can be pressed into fiber blankets, plates or woven fabrics to replace refractory bricks lining industrial high-temperature furnaces such as smelting, chemical, and glass. Firefighters can use fire-resistant fiber cloth to make clothes.
( 5 ) Using magnesia and bauxite clinker as raw materials and adding appropriate binder, the effect of pouring the whole barrel lining of steel drum is very good.
( 6 ) The manufacture of bauxite cement, grinding materials, ceramic industry and chemical industry aluminum compounds.
