FLUX FOR MODIFYING ALUMINUM ALLOYS Russian patent published in 2023 - IPC C22C1/06 C22C21/00 

FIELD: metallurgy.

SUBSTANCE: fluxes for melting cast aluminum-based alloys, used to modify the grain of aluminum alloys when producing shaped castings using various casting methods, including low-pressure casting. The flux contains, wt.%: potassium hexafluorotitanate 15-25, potassium tetrafluoroborate 7-15, potassium chloride and inevitable impurities - the rest.

EFFECT: providing possibility to grind the grain to a size of no more than 500 microns at a flux consumption of no more than 1 kg per ton of melt.
