Abstract:
[Problem] The present invention provides a method and an apparatus for melting aluminum cutting chips, in which the cutting chips that are dusts produced by cutting metal aluminum or an aluminum alloy are melted to produce an aluminum melt. [Solution] The method comprises: a preheating step for removing an oily water component from a cutting oil adhered to aluminum cutting chips by evaporation or decomposition; and a melting step for charging and diffusing the preheated cutting chips in an aluminum melt to melt the cutting chips. A melting apparatus is provided, which is configured such that the preheated aluminum cutting chips that are pushed and charged with a ceramic-made rotary cylindrical body arranged in the aluminum melt are diffused through a tip part while heating and melting the preheated aluminum cutting chips to melt the aluminum cutting chips.
