High Temperature Fire Resistant Refractory Bauxite Powder
?
Introduction:
?
They?have high refractoriness; resistant to deterioration and to influences of melted metal, slag and other melts.
They can be used in ferrous and non-ferrous metallurgy, cement industry, ceramic industry, glass industry, etc. The standard size is 230x114x64mm, also we can do as your request.
?
We have been exporting to Asia, Europe and Middle east etc. with stable quality and good reputation in the past fifteen years.and we have been running ISO9001-2000?and own?our own brand of DFL,?D-FB.?The stable quality, competitive price makes us win a large market in aboard, and we sincerely hope to serve you in this products, and we can do all as your request.

Main?Application:
?
1) aluminium industry.Used for defense, aerospace, automotive, electrical, chemical industry, daily necessities, etc.
(2) the precision casting.Alumina clinker made after mold precision casting processed into fine powder.Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.(3) for refractory products.High bauxite clinker as high as 1780 ℃ refractoriness, chemical stability strong, and good physical properties.
(4) aluminum silicate refractory fiber.With light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock.Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries.It is the high alumina clinker in the melting temperature of about 2000 ~ 2200 ℃ high temperature electric arc furnace, via high pressure of high temperature melting, high-speed air or steam injection, cooling, became a white cotton - silicate aluminum refractory fiber.It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical industry, glass and other industrial furnace lining brick.Firefighters available refractory fiber cloth to make clothes.
(5) with magnesia and bauxite clinker as raw material, adding proper binder, used for pouring ladle whole ladle lining has particularly good effects.
(6) manufacture alumina cement, abrasive materials, ceramic industry and chemical industry of aluminum compounds.
