Product description
CH Refractories manufactured rotary kiln calcined bauxite is made from selected bauxite ore and calcined by tunnel kiln. The content is from 60% Al2O3 to 88% Al2O3. Size is customized according to customers requirements, generally including 325 mesh, 200 mesh, 0-1/1-3/3-5mm.
Application:
Refractory materials. rotary kiln calcined bauxite is often used to make refractory castables, refractory bricks, refractory bricks, etc. due to its more stable physical properties and chemical stability. It is suitable for lining high-temperature industrial equipment, such as electrolytic cells, steel furnaces, etc.
2. Casting. rotary kiln calcined bauxite can be used to make casting coatings and precision castings, and is suitable for military, aerospace, communications, instrumentation, machinery and medical device sectors.
