Magnesium metal smelting device and reduction method
The invention discloses a magnesium metal smelting device and a reduction method. The smelting device comprises a first-stage material bin, a second-stage material bin, a flashboard sealing valve, an upper cover, a reduction tank, a first-stage crucible, a second-stage crucible, a crystallizer and a vacuum pump set. The reduction tank is vertically arranged, and the upper cover is arranged at the top end of the reduction tank. The upper cover is provided with a connecting port A and a connecting port B, and a conical three-way gas collecting hood is arranged between the upper cover and the reduction tank. A small port of the three-way gas collecting hood is connected to the connecting port A of the upper cover through a pipeline, and a side opening of the three-way gas collecting hood is connected to the connecting port B of the upper cover through a steam pipeline. The first-stage crucible and the second-stage crucible are sequentially and vertically arranged in the reduction tank. The device is reasonable in structural design, magnesium oxide and aluminum are used as raw materials, the raw materials are heated in the two stages of material bins and the two stages of crucibles at the same time to generate a reduction reaction, magnesium aluminate spinel is produced while crystal magnesium is produced, the whole production process is continuously circulated, the production capacity and efficiency are improved, energy consumption is reduced, and high economic benefits are created for enterprises.
一种金属镁冶炼装置及还原方法，冶炼装置包括一级、二级料仓、闸板密封阀、上盖、还原罐、一级、二级坩埚、结晶器和真空泵组；所述的还原罐竖直设置，其顶端设置有上盖；所述的上盖设置有连接口A及连接口B，上盖与还原罐之间设有锥形的三通集气罩；所述的三通集气罩小端口通过管道连接到上盖连接口A处，三通集气罩侧方开口通过蒸汽管道连接到上盖连接口B处；所述的一级坩埚和二级坩埚依次竖直设置在还原罐的内部。该装置结构设计合理，利用氧化镁和铝为原料，在两级料仓和两级坩埚内同时加热进行还原反应，生产结晶镁的同时还生产镁铝尖晶石，整个生产过程连续循环，提高了生产能力和效率，降低了能源消耗，为企业创造了较高的经济效益。
