CONDUCTIVE METAL MELTING FURNACE AND CONDUCTIVE METAL MELTING FURNACE SYSTEM WITH THE SAME AS WELL AS CONDUCTIVE METAL MELTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technique that melts a conductive metal reliably and quickly.;SOLUTION: A conductive metal melting furnace includes a magnetic field device made of a permanent magnet, the device that has an entrance for making electrically conductive molten metal flow in from the outside and an exit for discharging the molten metal to the outside, and has a permanent magnet in the vicinity of a drive flow path in a flow path having a vortex chamber provided between the drive flow path of the upstream side and the outflow path of the downstream side. The magnetic field device is rotated around a vertical axis and the magnetic field line of the permanent magnet is moved while being penetrated in the molten metal in the drive flow path. The molten metal is made to flow in the vortex chamber by electro-magnetic force generated with the movement, and the vortex of the molten metal is generated in the vortex chamber to be charged of the raw material. Then, the molten metal is discharged from the exit to the outside, and furthermore as needed, the molten metal in the outflow path is driven toward the exit with the electro-magnetic force by the movement of the magnetic field line.;SELECTED DRAWING: Figure 8;COPYRIGHT: (C)2017,JPO&INPIT
