8、 实现权利要求 1 的隧道式双循环真空冶炼炉的镁还原方法， 其特征是包括下列 步骤：
将融化的硅液倒入熔硅炉 A或熔硅炉 B内；
熔硅炉 A或熔硅炉 B内的硅液经保温管 A或保温管 B流进隧道式真空反应室； 向喷吹管吹入锻白粉与惰性气体，锻白粉与惰性气体与硅液一起进入隧道式真空反 应室；
加热隧道式真空反应室至温度 1260— 1900度并抽真空， 锻白粉与硅液反应生成金 属镁气体；
金属镁气体附着在锥形结晶套上， 经冷却形成镁结晶体；
当熔硅炉 A和熔硅炉 B内的硅液达到平衡时，硅液不再流动，这时通过交替升高顶 缸 A和顶缸 B， 熔硅炉 A和熔硅炉 B内的硅液就交替循环流动， 同时连续吹入锻白粉与 惰性气体， 就可实现连续反应、 连续生成镁结晶体。
