What is bauxite used for?


Bauxite is a kind of bauxite which is made of bauxite as raw material, sintered at 1500 ℃ to form a block, ground, bagged and processed by a crusher. The sieve fineness of bauxite is about 325 mesh. It is usually used in precision casting. Yyrefractory is a professional manufacturer of all kinds of refractory grade bauxite.


1. Aluminum industry. It is used in the fields of national defense, aviation, automobile, electrical appliance, chemical industry, daily necessities and so on. Precision casting. The bauxite clinker is processed into fine powder and made into a precision casting mold. Suitable for military, aerospace, communications, instrumentation, machinery and medical equipment and other sectors.


3. Refractory products. The refractoriness of bauxite clinker is as high as 1780℃, with strong chemical stability and 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 resistance to mechanical vibration. Used in steel, non-ferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, national defense and other industries. The high-alumina clinker is put into a high-temperature electric arc furnace with a melting temperature of about 2000-2200 °C. After high temperature melting, high pressure and high speed air or steam jet cooling, it becomes a white "cotton"-like aluminum silicate refractory fiber. It can be pressed into fiber felt, cardboard or woven cloth, instead of refractory brick, used for high temperature furnace lining in smelting, chemical, glass and other industries. Firefighters can use fire-resistant fiber cloth for clothing.


5. Using magnesia and bauxite clinker as raw materials, adding an appropriate amount of binder, pouring the inner lining of the overall cylinder, the effect is good.


6. Manufacture of bauxite cement, abrasives, ceramics industry and chemical industry can prepare a variety of aluminum compounds.

What is refractory ?

  What is refractory ? Refractory refers to the temperature in degrees Celsius at which a conical specimen of refractory material can withstand the action of high temperatures without softening and melting under no load. However, refractories cannot be completely described by the definition of refractoriness, and 1580°C is not absolute. Yyrefractory refractory raw materials are a class of inorganic non-metallic materials whose refractoriness is not lower than 1580℃. Materials now defined whose physical and chemical properties allow their use in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, electric power and other industrial fields. They are used the most in the metallurgical industry, accounting for 50%-60% of total production. The workability of refractory materials includes consistency, slump, fluidity, plasticity, cohesion, resilience, co...
