Abstract:
1. A melting furnace with agitator comprising: a metal furnace for containing a melt, the metal furnace having a metal melting furnace main body and a lateral bypass passage; a side wall of the metal melting furnace main body having a metal melting furnace main body outlet and a metal melting furnace main body inlet; an agitator arranging space formed between an outer side surface of the side wall of the metal melting furnace main body and an inner side surface of the bypass passage, an agitator located in the agitator arranging space, the agitator being opposite to an inner side surface of the bypass passage, and having a casing and a rotating magnet assembly within the casing such that the rotating magnet assembly is rotatable supported by a vertical shaft, the rotating magnet assembly having one or more permanent magnets, wherein magnetic flux from the one or more permanent magnets penetrates the melt in the bypass passage and returns to the one or more permanent magnets, moving the melt in accordance with a rotation of the one or more permanent magnets such that the magnetic flux drives the melt in the bypass passage to flow in the bypass passage, the flow of the melt in the bypass passage flowing into the melt in the metal melting furnace main body to result in flow converging, and causing melt in the metal main body to flow into the bypass passage to flow into the bypass passage, to result in flow dividing, wherein the flow converging and the flow dividing is continuously performed according to the continuous rotation of the magnet assembly.
