The recovery method of a high-temperature alloy slag waste heat recovery device according to claim 4, characterized in that: The following steps are involved: S1: high-temperature alloy slag is poured into the inner tube (6) through the feed pipe (3), and the waste heat of the high-temperature alloy slag is discharged through the outlet pipe (5). The outlet pipe (5) is connected to a device that needs to use heat to recycle the waste heat of the high-temperature alloy slag; S2: water flows into the outer tube (1) through the water inlet pipe (8) and the hard pipe (7), and the waste heat of the high-temperature alloy slag heats the water, and the waste heat of the high-temperature alloy slag is recycle; S3: The output shaft of the servo motor (113) drives the spiral conveying plate (114) to rotate, and the spiral conveying plate (114) conveys the high-temperature alloy slag to the right, stirs the high-temperature alloy slag, and disperses the high-temperature alloy slag; S4: The output shaft of the servo motor (113) drives the scrambler (122) to rotate, and the scrambler (122) scrambles the high-temperature alloy slag in the inner tube (6) to make the high-temperature alloy slag more dispersed.
