Melt Treatment Fluxes

For more than half a century, HOESCH has been developing melt treatment agents in the Dursalit ® product range. The cleaning and treatment of the molten aluminum is a decisive step towards the optimum quality of the melt. Thereby can non-metallic inclusions and interfering elements are removed, which can otherwise lead to casting defects and high scrap rates in production.

Each smelting process produces a slag with a high metal content. Special salt formulations are used to recover the valuable metal from the slag and separate it cleanly from the liquid metal. Thus, from a commercial as well as environmental point of view, the treatment of aluminum slag is a necessary step to improve production performance.

HOESCH Melt Treatment Fluxes are used worldwide in smelters, semi-finished product and remelting plants as well as mold foundries for light metal casting for covering, cleaning, degassing, gassing, grain refining , refining and slag treatment. HOESCH offers a special product range for heavy metal casting.
