在皮江法炼镁中,真空度对结晶镁的产量、质量影响至关重要。真空度越高,相应的剩余压力越低,还原时硅的利用率越高,得到的金属镁越致密,并有平滑的表面和金属光泽。真空度低,相应的剩余压力就高,得到的是树枝状、网状、粉状等呈疏松、分散而脆的镁,且无金属光泽,并在出镁和精炼时易氧化烧损,直接影响镁的实收率和质量。 In Pidgeon magnesium, the degree of vacuum on the production of crystalline magnesium, the quality of the impact is crucial. The higher the degree of vacuum, the lower the corresponding residual pressure, the higher the utilization of silicon during reduction, the more dense the resulting metallic magnesium is, with a smooth surface and metallic luster. The degree of vacuum is low, the corresponding residual pressure is high, resulting in dendritic, reticular, powder and other loose, scattered and crisp magnesium, and no metallic luster, and in the magnesium and refining easy oxidative burning directly Affect the actual yield and quality of magnesium.
