Abstract

PURPOSE: To enable the reuse of metallic chips having no moisture and no oil content without oxidizing them by heating from the inner part with high-frequency induction current after press-forming the metallic chips and vaporizing the stuck moisture and oil contents. CONSTITUTION: The metallic powdery chips 1 easily oxidized is charged into a hopper 13 with a transporting means 12 and press-formed to make the briquettes 2 and the briquettes are charged into a vessel provided with a high-frequency induction coil 20 at the outside while shifting with a conveyor 15. Electric current is conducted to the coil 20 and the briquettes 2 are heated from the inner part with the induction current, and the moisture and the oil contents stuck to the chips are heated and vaporized to be left from the briquettes 2. The moisture becomes steam and the oil content becomes C and H by vaporization and decomposition, and C and H are reacted with O2 in the air and removed as CO2 and H2 O. The O2 in the air at the outer periphery of the chip briquettes 2 are reduced by this reaction, and the chip briquettes 2 having no moisture and oil contents without being oxidized are recovered into a shipping cart 16 as non-oxidized chip briquettes 2.

2. Description of the Related Art It is strongly desired to reuse cutting dust (Dari powder) generated when cutting a metal material from the viewpoint of resource saving. In the case of aluminum alloy-based chips, since the specific gravity of the chips is small, the oxidation reaction on the surface of the chips suspended when the chips are added to the molten metal is strong, and a large amount of slag such as aluminum oxide is generated. . Therefore, it is necessary to lump the chips and put them in the molten metal. Further, since water and oil are attached to the cutting chips, if the cutting chips are lumped and redissolved, black smoke is generated and the factory environment is deteriorated.

[0003] Therefore, a technique proposed by the present applicant has previously proposed a technique in which the cutting dust in the form of chips is put under reduced pressure to vaporize water and oil adhering to the cutting dust and to make the cutting dust into a lump. (Japanese Patent Laid-Open No. 6-287648). In this method of producing a cutting waste mass, the cutting waste is placed under a reduced pressure, so that the oxidation of the cutting waste at the time of removing water and oil is suppressed, and the quality deterioration due to the oxidation of the cutting waste is prevented.

When the swarf 2 is carried into the furnace wall 22, the lower part of the furnace wall 22 is closed by the lower door 23. When the lower door 23 is completely closed, the high-frequency coil 20 is energized to start the high-frequency heating of the cutting waste mass 2. Since the cutting waste mass 2 is heated from the inside by high-frequency heating, water and oil vaporized inside the cutting waste mass 2 are jetted to the outer peripheral surface of the cutting waste mass 2. Here, C, H generated by vaporization of oil
Is combined with O 2 existing on the outer periphery of the cutting waste mass 2 to form CO 2
And H 2 O, the O 2 on the outer periphery of the cutting waste mass 2 is deficient, and the cutting waste mass 2 is prevented from being oxidized.

Further, by heating the cutting waste mass 2 from the inside, the surface temperature of the cutting waste mass 2 rises more slowly than in the case where it is simply heated from the outside by a heater or the like. The antioxidant effect of the surface of the is enhanced. Oxidation of the swarf 2 progresses even in the presence of a slight amount of oxygen.
As shown in FIG.
By covering it with 2 or the like, it is possible to suppress the entrapment of air into the furnace wall 22, and the effect of preventing the cutting waste mass 2 from being oxidized is further enhanced.

Moisture and oil vaporized from the cutting waste mass 2 by high frequency heating rises as it is and is captured by the dust collector 26. The cutting waste mass 2 from which the water content and the oil content have been removed is transferred to the conveyor 15 again and conveyed to the delivery yard 16. The cutting waste mass 2 conveyed to the shipping yard 16 is reused when manufacturing a product made of an aluminum alloy.
Since the water and oil are almost completely removed from the cutting waste mass 2, black smoke is not generated even when the cutting waste mass 2 is redissolved.
