Welding fluxes are a small but valuable market for calcined bauxite. Techniques for submerged arc welding require the use of a
granular flux to shield the molten weld pool rom the atmosphere during the weld's application or pacement. Various proprietary
compositions exist and in some cases calcined bauxite is incorportated into these formulations. Calcined bauxite may, in some
instances, make up to 25% of the welding flux.
Typical data of welding grade calcined bauxite:
Normal grain size of welding grade calcined bauxite:
100mesh;200mesh; 325mesh; or as customer's requirement.
