| titleOfInvention | Flux for refining aluminum and its alloys in melting furnace |
| abstract | The invention relates to non-ferrous metallurgy, specifically to the flux treatment of aluminum and its alloys. The invention makes it possible to produce aluminum or its alloy treated with the proposed flux with a low content of sodium impurities, as well as to ensure the possibility of processing slag formed during smelting in aluminum electrolytic cells due to reduction into magnesium flux containing magnesium chloride, additionally barium chloride and or calcium and aluminum sulphate in the following ratio, wt.%: barium and / or calcium chlorides 35-45; aluminum sulfate 5-15, magnesium chloride else. A decrease in the content of sodium impurities in the alloy is achieved by increasing the refining properties of the flux, which is ensured by the decomposition of aluminum sulfate with the release of the active oxidant sodium sulfuric anhydride. Barium and / or calcium chlorides mixed with magnesium chloride allow maintaining a low melting point of the flux, which does not require an increase in the potassium-containing components, thus preventing the latter from saturation of the slags formed during smelting, thereby eliminating their harmful effect on the bottom hearth. aluminum electrolysis cells. The processing of slags in the latter becomes possible and expedient. 2 tab. 2 (L |
