Abstract
A magnetic field device of a molten metal driving device includes iron cores, yokes coupling the iron cores, coils wound around the iron cores so as to sandwich the yoke, coils wound around the iron cores so as to sandwich the yoke, and coils wound around the iron cores so as to sandwich the yoke, the coils being wound so as to generate a magnetic field toward the yoke when a first-phase current flows, the coils being wound so as to generate a magnetic field toward the yoke when a second-phase current flows, the coils being wound so as to generate a magnetic field toward the yoke when a third-phase current flows.
Claims15
A molten metal driving device for driving molten metal, the molten metal driving device comprising:
- a plurality of iron cores;
- a first yoke that couples the plurality of iron cores;
- a second yoke that is adjacent to the first yoke and couples the plurality of iron cores;
- a third yoke that is adjacent to the second yoke and couples the plurality of iron cores;
- a first coil and a second coil wound around at least one of the plurality of iron cores so as to sandwich the first yoke;
- a third coil and a fourth coil wound around at least one of the plurality of iron cores so as to sandwich the second yoke;
- and
- a fifth coil and a sixth coil wound around at least one of the plurality of iron cores so as to sandwich the third yoke, wherein
- both the first coil and the second coil are wound so as to generate a magnetic field toward the first yoke when a first-phase current flows, both the third coil and the fourth coil are wound so as to generate a magnetic field toward the second yoke when a second-phase current flows, and both the fifth coil and the sixth coil are wound so as to generate a magnetic field toward the third yoke when a third-phase current flows.
A molten metal driving method for driving molten metal, the molten metal driving method comprising:
- disposing a molten metal driving device including a magnetic field device so as to be adjacent to a furnace that stores the molten metal, a trough that conveys the molten metal, or a mold;
- the magnetic field device including:
- a plurality of iron cores;
- a first yoke that couples the plurality of iron cores;
- a second yoke that is adjacent to the first yoke and couples the plurality of iron cores;
- a third yoke that is adjacent to the second yoke and couples the plurality of iron cores;
- a first coil and a second coil wound around at least one of the plurality of iron cores so as to sandwich the first yoke;
- a third coil and a fourth coil wound around at least one of the plurality of iron cores so as to sandwich the second yoke;
- and a fifth coil and a sixth coil wound around at least one of the plurality of iron cores so as to sandwich the third yoke, and
- causing a first-phase current to flow through the first coil and the second coil to generate a magnetic field toward the first yoke, causing a second-phase current to flow through the third coil and the fourth coil to generate a magnetic field toward the second yoke, and causing a third-phase current to flow through the fifth coil and the sixth coil to generate a magnetic field toward the third yoke.
