Agitator, agitating method, and melting furnace with agitator

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.

Description

technical field [0001] The invention relates to a stirring device and method, and a melting furnace with a stirring device using the stirring device. Background technique [0002] Conventionally, Al, Cu, Zn, or alloys of at least two of them, or scrap metals such as conductors (conductors) such as Mg alloys, etc., are dissolved, formed into billets, and commercialized. At this time, in order to make the quality of the billet uniform, the aluminum etc. in the melting furnace should be fully stirred. Therefore, a stirring rod is put into a melting furnace to artificially stir the molten aluminum or the like, or an electric stirring device is installed at the bottom of the furnace, and the molten aluminum or the like is stirred by the device. [0003] In the case of the above-mentioned artificial stirring in the prior art, it becomes the operation under the severe environment of ultra-high temperature, and the adverse effect on the operator cannot be ignored. Furthermore, in ...

Problems solved by technology

In addition, although a coil is used to form a magnetic field, in order to suppress the oscillation of the coil, it must be cooled reliably. Not only must careful attention be paid to cooling, but the overall complexity of the device will inevitably increase the cost.

As a result, the current situation is that the device as a whole becomes an expensive device, and a large capital investment is required to adopt it, so it cannot be easily adopted.
