Изобретение относится к области металлургии цветных металлов, в частности к способам очистки от примесей тяжелых металлов алюминия и его сплавов. Цель изобретения - повышение технико-экономических показателей процесса очистки. В способе очистки в расплав алюминия и его сплавов вводят бор с одновременным воздействием на него турбулентных пульсаций электромагнитного поля, которые поддерживают в течение всего периода разливки расплава.The invention relates to the field of metallurgy of non-ferrous metals, in particular to methods for purification from impurities of heavy metals of aluminum and its alloys. The purpose of the invention is to increase the technical and economic indicators of the cleaning process. In the cleaning method, boron is introduced into the melt of aluminum and its alloys with simultaneous exposure to it of turbulent pulsations of the electromagnetic field, which are maintained during the entire period of casting of the melt.
