Embodiment 1
[0031] The preparation method of the rare earth magnesium alloy product of the present invention comprises the following steps successively:
[0032] (1) Rare earth chloride salt pretreatment: After the rare earth chloride salt is subjected to dehydration and separation pretreatment, it is used as a raw material for the next step of molten electrolysis; the rare earth chloride salt is cerium chloride. The pretreatment of the dehydration separation adopts the chloride salt melting-dehydration coupling process, and the chlorine gas generated by the anode during the electrolysis of the rare earth chloride salt is used for gas-liquid contact with the molten rare earth chloride salt to realize dehydration and separation, so that the hydrolyzate produced during dehydration is Chlorination becomes RECl3 Add rare earth chloride salt melt.
[0033] (2) Molten electrolysis: Put the dehydrated rare earth chloride salt obtained in step (1) in a molten electrolysis equipment, use graphite ...
