PROCEDURE FOR REFINING ALUMINIUM ALLOYS Russian patent published in 2010 - IPC C22B9/10 C22C1/06 C22B21/06

Abstract RU 2396365 C1

FIELD: metallurgy.

SUBSTANCE: procedure for refining aluminium alloys consists in treating melt at temperature 750-760°C with briquette flux containing organic or non-organic binding, chlorides, fluorides and refractory fillers in form of dispersed particles of high melting aluminium and silicon oxides. When organic binding is used, flux has the following chemical composition, wt %: KCl 2.0-10.0; NaCl 2.0-10.0; organic binding 2.0-3.0; SiO₂ or Al₂O₃·2SiO₂ - the rest. 20-30 % water solution of salt constituent of flux is used as non-organic binding.

EFFECT: increased refining property and efficiency of process.
