Product Description
Bauxite
Bauxite ore (powder) is a kind of fine powder processed by Raymond mill after calcining bauxite ore. Its particle size is usually 100-325 mesh. It is a new type of silicon-aluminum high-grade refractory material. Surface coating and sanding material suitable for investment casting and also used as refractory aggregate for other casting coatings. Bauxite ore is widely used in the refractory industry because of its small expansion coefficient, high refractoriness and good chemical stability. It is a commonly used refractory material for lost foam cast steel and cast iron coating. The bauxite powder used in the foundry industry mainly produces various casting coatings, such as lost foam coatings, refractory aggregates for various sand casting coatings, and powder for investment casting surfaces, which require low impurity content and high alumina content.

Aluminum Industry Precision Casting
application
(1) Aluminum industry. Applied in national defense, aviation, automobile, electrical appliance, chemical industry, daily use
necessities etc.
(2) Precision casting. The bauxite clinker is processed into a fine powder to make molds for precision casting. For the military,
sectors such as aerospace, communications, instrumentation, machinery and medical equipment.
(3) For refractory products. High alumina clinker has a refractoriness of 1780°C, strong chemical stability and good physical properties
characteristic.
(4) Aluminum silicate refractory fiber. It has the advantages of light weight, high temperature resistance and good heat dissipation
Good stability, low thermal conductivity, small heat capacity, and mechanical vibration resistance. It is used in many industries such as
Such as iron and steel, nonferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense,
It is to put the high-alumina clinker into a high-temperature electric arc furnace, and the melting temperature is about
2000-2200℃, melted at high temperature, blown into high-pressure and high-speed air or steam to cool, and become white
"Cotton" - aluminum silicate refractory fiber. Can be pressed into fiber blankets, boards or woven into cloth instead
Refractory brick lining for smelting, chemical, glass and other industrial high-temperature kilns. firefighters can use
Refractory fiber cloth is used to make clothes.
(5) Using magnesia and bauxite clinker as raw materials, adding an appropriate binder, the overall lining effect of the ladle is
very good.
(6) It can be used in the manufacture of high alumina cement, abrasive materials, ceramic industry and chemical industry
