AdTech is dedicated to research and development, production, and market of covering flux for preventing the molten metal from oxidizing and absorbing during the aluminum alloy casting process. Aluminum alloy is easy to absorb hydrogen and oxidize, sprinkling covering flux so that a dense protecting cover is formed to keep the purity of the molten metal. All the covering flux is with appropriate heat treatment, removed absorbed water and crystal water, and screened to uniform size. Molten covering flux will form a dense protecting cover on the surface in a short time, with less viscosity and good flow ability, so as to prevent molten aluminum from oxidizing and absorbing. Covering flux applies to the casting process of multi-series aluminum alloy products, such as micron-sized aluminum foil raw material, PS baseboard for printing, canning material, elastic packaging material, railway transportation, aerospace products, cable& wire, and other molten aluminum degassing, deslaging, purifying.

Applications for Covering Flux
AdTech’scovering flux is white powdery fine particles. The main ingredients are chloride and villiaumite, together with other compounds. Spray it with gas from a refining jar as a carrier, and sprinkling it directly to the surface of molten metal manually is permitted. Stir molten metal with covering flux to achieve inclusion removing purpose. It is used for aluminum, non-high magnesium-aluminum alloy, and strontium modifying aluminum alloy covering in the furnace, highly decreases metal loss caused by liquid oxidizing, and reduces oxidizing burning loss. The covering process also forms a physical barrier between molten aluminum and oxidizing gas in the furnace, reducing oxide inclusion forming in molten aluminum, creating a separating effect and good for casting quality. Covering flux helps to meet the requirement of high value-added & high-tech performance aviation, transportation, and another aluminum alloy precise casting.
