Welding Grade Calcined Bauxite For Welding Flux

Welding Grade Bauxite   Welding grade bauxite has tight regulation on presence of sulfur and phosphorus which are detrimental to the weld. When present at high concentrations, they induce porosity and cracking, and at lower concentrations, they adversely affect the impact strength of the weld. And moisture for welding grade bauxite should not exceed 0.5% because the potential for any moisture present withthin the flux to reduce to hydrogent, if exposed to a welding arc, the molten weld pool absorbs the hydrogen and will induce brittleness into the weld.     Application   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.     SINOCEAN Available Welding Grade Bauxite   Item  SNW85  SNW83  Al2O3(%)  85.0min  83.0min  SiO2(%)  8.0max  9.0max  Fe2O3(%)  1.8max  2.0max  K2O(%)  0.5max  0.3max S(%)  0.02max  0.02max P(%)  0.05max  0.05max Specification        Available powder size  80mesh; 100mesh; 200mesh; 325mesh; or as customer's requirement.    Package 1MT Jumbo bag Standard exporting package for sea transportation or air delivery Special packing requirement is acceptable   Company information: Sinocean Industrial Limited is an investor, producer and supplier of calcined bauxite & related products to a wide variety of industries throughout the world.
