Chaotic stirring device and method combining plasma arc smelting and permanent magnet

A chaotic stirring method combining plasma arc smelting and permanent magnet, applied to a chaotic stirring device comprising a furnace body, wherein the furnace body comprises a water-cooled copper crucible;

• the center of an upper surface of the water-cooled copper crucible comprises a groove for placing raw metals;
• the water-cooled copper crucible comprises an internal hollow cavity, wherein a return pipe is disposed directly below the groove in the hollow cavity;
• an upper end of the return pipe is vertically upward, and is horizontally provided with a filter screen;
• a spherical magnet is placed between the filter screen and the groove;
• one side of the water-cooled copper crucible is provided with a first water inlet pipe and a first water outlet pipe, wherein the first water inlet pipe is connected to the hollow cavity, and the first water outlet pipe is connected to the bottom of the return pipe, to form a water flow passage in the water-cooled copper crucible;
• wherein the stirring method comprises:
• placing raw metals in the groove of the water-cooled copper crucible;
• starting a tungsten electrode, and conducting plasma arc smelting of the raw metal in the water-cooled copper crucible;
• and
• opening a water inlet valve and a water outlet valve, to continuously inject cooling water into the water-cooled copper crucible and a nozzle, and continuously discharge water in the water-cooled copper crucible and the nozzle.
