Continuous production equipment and continuous production method for magnesium metal

Abstract

The invention discloses continuous production equipment and a continuous production method for a magnesium metal. The continuous production equipment comprises a charging device, a reduction room, a crystallizer and a deslagging room. The charging device, the reduction room, the crystallizer and the deslagging room are provided with vacuum detectors and communicate to a vacuum device. The chargingdevice is located above the reduction room and communicates to the reduction room, a material isolating valve is arranged between the charging device and the reduction room, the deslagging room is arranged right below the reduction room, the reduction room communicates to the deslagging room and a deslagging isolating valve is arranged between the reduction room and the deslagging room, and the crystallizer communicates to the upper side of the reduction room; the inner wall of the reduction room is a graphite crucible, titanium boride is plasma sprayed to the surface of the graphite crucible, and an electromagnetic induction heating device is arranged in the reduction room, so that no other heating devices are available in the reduction room, and therefore, the equipment is large in space and quick and uniform to head, the reaction time can be saved obviously and a slag adhesion phenomenon can be also avoided.

Description

technical field [0001] The invention relates to the technical field of metal magnesium production equipment, in particular to continuous production equipment and a continuous production method of metal magnesium. Background technique [0002] In the prior art, metal magnesium production equipment is equipped with a reduction chamber, which adopts resistance heating, and the diameter of the reduction chamber is slightly larger, resulting in uneven heating. In addition, multi-layer heating plates are used in the reduction chamber, and electrode heating is also used. Due to the existence of these heating plates and electrodes in the reduction chamber, the actual application space is reduced. More importantly, the temperature near the heating plate and electrodes will be higher than other areas, and the slag will become molten and sticky slag will appear. This is also a common and difficult problem in continuous magnesium smelting in shaft furnaces. Contents of the invention ...
