Summary: | The invention provides an aluminum-lithium alloy melt purification method which comprises the following steps: proportioning alloy raw materials, and carrying out primary smelting to obtain a primary melt; electromagnetic stirring is adopted to stir the primary melt; under the action of a magnetic field, the stirred primary melt is subjected to secondary smelting, and a secondary melt is obtained; the secondary melt is refined, and a third melt is obtained; and the third-time melt is subjected to standing, slagging-off and filtering, and the purified melt is obtained. The invention provides a method for improving the cleanliness of the aluminum-lithium alloy melt by adding trace rare earth elements and combining a multi-configuration electromagnetic field purification and vacuum degassing technology and a tubular filtration technology, and a support is provided for manufacturing a high-quality aluminum-lithium alloy material.
