Изобретение относится к области металлургии и может быть использовано при приготовлении алюминиево-литиевых сплавов. Способ включает обработку расплава флюсом, основой которого является хлористый литий, присадку лития в расплав, рафинирование расплава. Новым в способе является то, что расплав обрабатывают обезвоженным хлористым литием, а в печное пространство подают инертный газ влажностью не более 20 ррт. Инертный газ в пространстве печи периодически, в том числе после рафинирования расплава, обновляют. Давление инертного газа в пространстве печи поддерживают ниже атмосферного.The invention relates to the field of metallurgy and can be used in the preparation of aluminum-lithium alloys. The method includes treating the melt with flux, which is based on lithium chloride, lithium additive in the melt, melt refining. A new method is that the melt is treated with dehydrated lithium chloride, and an inert gas with a moisture content of not more than 20 ppm is fed into the furnace space. The inert gas in the furnace space is periodically updated, including after the refining of the melt. The inert gas pressure in the furnace space is maintained below atmospheric.
