Product Description

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.
