satafluxes

  Flux is a compound added to the molten aluminum bath to improve the quality of castings. They are mixed for specific processes and application areas. The flux assists in surface protection, scum treatment, furnace wall cleaning, metal cleaning, hydrogenation and crystal refinement.   Aluminum alloy fluxes are added during the smelting of aluminum and aluminum alloys to remove oxide inclusions and alkali metals and other impurities in the aluminum solution, and are mostly solid composite salts.   The advantages of aluminum alloy flux include: 1. Extend furnace life 2. Reduce pollution 3. Improve the quality of aluminum alloy by reducing waste and melt loss 4. Provide aluminum alloy special formula 5. Higher process efficiency 6. Reduce the cost of scum treatment 7. Improve metal recovery rate   JINZHOU SATA FUSED FLUXES AND NEW MATERIALS FACTORY has an independent flux formulation development department, which can provide different formulations according to customer...

In the normal composition in the Aluminium alloy flux, the commonly recipe including fluorides and chlorides, rare earth compounds should be used as preferred additives, including rare earth halides, rare earth carbonates or other rare earth compounds. In addition, K2CO3, Na2CO3, CaCO3, NaF, KNO3, CaCl2, CaSO4 and graphite can be used as auxiliary additives as required. The role of each component: (1) Fluoride: It plays a refining role, it can absorb and dissolve Al2O3, and it also can properly control the melting point of mixed salts to increase the purification effect. As a surfactant, alkali metal fluoride salt can reduce the surface tension between the flux and the melt, and between the flux and the oxide inclusions. The limited solubility of alkali metal salts in oxidized inclusions ensures that the flux can penetrate the oxide film. Common fluoride salts such as Na3AlF6, CaF2 and Na2SiF6 can be added to 20% (mass fraction). CaF2 can also increase the surface tension of the mixed...
