Product Description

RKB 87 86 85 Rotary Kiln Calcined Bauxite

Product Description

Calcined bauxite is produced from non-metallurgical bauxite grades with a high diasporic content through sintering in rotary kilns at 1650-1700 ° C. There are two types of kilns for the calcination process: rotary kiln bauxite and shaft furnace bauxite.
Most important characteristics are high thermal stability, high mechanical strength and good resistance to molten slags.
Application
1. Aluminum industry. Used in national defense, aerospace, automotive, electronics, chemical industry, daily necessities, etc.
2. Precision casting. Alumina clinker manufactured after precision mold of fine powder processed mold. Used in the military, aerospace, communications, instrumentation, machinery and medical equipment department.
3. refractory products. The high refractoriness of bauxite clinker is as high as 1780, strong chemical stability and good physical properties.
4. Refractory fiber of aluminum silicate. Used in iron and steel, non-ferrous metallurgy, electronics, petroleum, chemistry, aerospace, nuclear power, defense, and other industries.
5. Magnesia and bauxite clinker as raw material, add the appropriate binder, used to pour the ladle. The ladle coating has particularly good effects.
6. Alumina cement, abrasive materials, the ceramic industry and the chemical industry can be made of aluminum with various compounds.
