The invention discloses an aluminum-lithium alloy waste continuous recovery method which comprises the following steps: S1, obtaining aluminum-lithium alloy scraps and scrap waste, and performing pretreatment; s2, aluminum-lithium alloy bulk waste materials are obtained and put into a smelting furnace to be smelted, and metal mother liquor is obtained; s3, adding the aluminum-lithium alloy chippings and fragment waste of preset weight into the metal mother liquor in batches, controlling the heating temperature and the heating time of the metal mother liquor, and stirring the metal mother liquor until the aluminum-lithium alloy chippings and the fragment waste are completely molten to obtain molten metal; and S4, when the weight of the molten metal is larger than or equal to the target weight, scum in the molten metal is removed, part of the molten metal is poured into the casting device, the remaining molten metal is used as metal mother liquor, and the step S3 is repeated. According to the method provided by
