FIELD: refining of metals.
SUBSTANCE: proposed method includes blowing gas suspension through lance immersed in melt at simultaneous introduction of high-velocity jet of neutral gas into area of delivery of gas suspension directly in melt of metal. Introduction of high-velocity gas is performed through gas suspension supply lance. Flux or modifying compounds in powder state may be used as gas suspension component. During treatment, pressure of gas is maintained at level no less than 8 atm; supply of gas is carried out through one or several nozzle of lance at diameter of hole not exceeding 1.5 mm. Proposed method enhances assimilability of flux materials in molten aluminum reducing slag formation by 1.6-1.7 times and content of aluminum oxide in slag by 1.2-2.5 times.
EFFECT: enhanced efficiency.
