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.
