Abstract
An agitator for agitating a melt includes a heat-resistive container having a blast opening through which cooling air is blown and an exhaust opening for exhausting air having been subjected to heat exchange, and a rotating magnet assembly composed of a permanent magnet housed in the heat-resistive container in a rotatable manner, magnetic lines of force emitted from the permanent magnet penetrating through the heat-resistive container to exit outside, and then penetrating the heat-resistive container again to return to the permanent magnet.

An agitator for agitating a melt, comprising:
- a heat-resistive container having a blast opening through which cooling air is blown and an exhaust opening for exhausting air having been subjected to heat exchange;
- and a rotating magnet assembly composed of a permanent magnet housed in the heat-resistive container in a rotatable manner, magnetic lines of force emitted from the permanent magnet penetrating through the heat-resistive container to exit outside, and then penetrating the heat-resistive container again to return to the permanent magnet.
A method of agitating a melt in a melting furnace main body, in which
- an agitator is provided inside or outside the melting furnace main body, the agitator including:
- a heat-resistive container having a blast opening through which cooling air is blown and an exhaust opening for exhausting air having been subjected to heat exchange;
- and
- a rotating magnet assembly composed of permanent magnets housed in the heat-resistive container in a rotatable manner, magnetic lines of force emitted from the permanent magnets penetrating through the heat-resistive container to exit outside, and then penetrating the heat-resistive container again to return to the permanent magnet, and
- the rotating magnet assembly of the agitator is rotated to agitate the melt in the melting furnace main body.
An agitator for agitating a melt comprising:
- a casing including a casing body of a nonmagnetic material, and a top cover covering the casing body, the top cover having a first opening for blowing air, which connects an inside and an outside of the casing, and a second opening for discharging air;
- and
- a rotating magnet assembly housed in the casing and supported so as to be rotatable around a substantially vertical axis, the rotating magnet assembly having an upper rotation axis and a lower rotation axis, at least the upper rotation axis being a hollow body, the upper rotation axis connecting to the outside of the casing through the first opening so that it is possible to send air from the outside to the inside of the casing, the rotating magnet assembly being magnetized so that different magnetic poles are alternately arranged along the outer periphery thereof.
An agitator for agitating a melt comprising:
- a heat-resistive container;
- and
- a rotating magnet assembly rotatably housed in the heat-resistive container,
- wherein:
- a hollow rotation axis penetrating the rotating magnet assembly is fixed to the rotating magnet assembly, the rotation axis rotatably mounting the rotating magnet assembly to the heat-resistive container;
- one end of the hollow rotation axis penetrates the heat-resistive container to exit outside so that cooling air can be introduced from outside, another end has an opening in the heat-resistive container, and the heat-resistive container has an opening for discharging the introduced air to the outside;
- and
- the rotating magnet assembly is magnetized so that different magnetic poles are alternately arranged around the rotation axis along an outer periphery thereof.
