Abstract

A process for manufacturing a reclaimed alloy material includes the steps of crushing a magnetic core including an amorphous alloy ribbon; putting a prepared organic solvent and crushed pieces obtained in the step of crushing into a container and putting the crushed pieces into contact with the organic solvent in the container; selectively discharging the organic solvent from the container after putting the crushed pieces into contact with the organic solvent; and evaporating, after discharging the organic solvent, the organic solvent remaining in the container. The crushed pieces, removed from the container after the organic solvent is evaporated, is reused as a reclaimed alloy material.

First claim

The invention claimed is:

1. A process for manufacturing a reclaimed alloy material, comprising the steps of:
crushing a magnetic core including an amorphous alloy ribbon into crushed pieces;
putting a prepared organic solvent and the crushed pieces into a container, wherein the container includes a cylindrical shape and is rotatably supported around a central axis of the cylindrical shape as a rotation shaft;
putting the crushed pieces into contact with the organic solvent in the container;
sealing the container with an airtight lid;
cleaning the crushed pieces, and rotating the container at a rotation rate of 1 to 3 rotations per minute;
selectively discharging the organic solvent from the container after putting the crushed pieces into contact with the organic solvent and cleaning the crushed pieces; and
evaporating, after discharging the organic solvent, the organic solvent remaining in the container;
removing the crushed pieces after the organic solvent is evaporated, and reusing the crushed pieces as a reclaimed alloy material,
wherein the container includes a plurality of fins positioned to protrude to an inner position of the container from an inner circumferential surface thereof,
wherein each fin of the plurality of fins protrudes a length of 20 to 50% of an inner radius of the container.

2. The process according to claim 1 , wherein evaporating the organic solvent remaining in the container comprises decreasing a pressure inside the container and heating an outer circumferential portion of the container to evaporate the organic solvent remaining in the container after the organic solvent is discharged.

3. The process according to claim 1 , wherein putting the crushed pieces into contact with the organic solvent comprises putting the crushed pieces into contact with the organic solvent in a flow of the organic solvent generated by moving the container.

4. The process according to claim 1 , further comprising magnetically adsorbing and thus separating the crushed pieces by a magnetic separation device.

5. The process according to claim 1 , wherein the magnetic core crushed by a biaxial shearing crusher.

6. The process according to claim 1 , wherein the organic solvent is put into the container at a temperature between 40° C. and 100° C.

7. The process according to claim 1 , wherein the outer circumferential portion is heated using steam.
