Embodiment Construction
[0044] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0045] Coarse magnesium produced by the silicothermal reduction process generally has a loose outer layer of "dust + magnesium particles" and an inner layer of "crystalline magnesium" ( figure 1 ) structural characteristics, the thermal resistance of the surface layer is high and does not infiltrate with the melt, and there is a technical bottleneck of refractory melting, combined below figure 2 The application of the present invention in refining production of crude magnesium is introduced. The implementation device includes the following main components ( figure 2 ): crucible 3, melting chamber 4, flux filter 5, flux circulation purification pump 6, flux slag port 7, feed port 8, refining air pipe 9 and melting-promoting refining pump 10.
[0046] The crude magnesium charge is fed into the melting chamber 4 of the built-in molten flux crucible 3 through...
