| titleOfInvention | Continuous production method of high-quality multi-element rare earth magnesium alloy with controllable end point component |
| abstract | The invention discloses a continuous production method of high-quality multi-element rare earth magnesium alloy with controllable end point components, which comprises the following steps: s1, adding a metal magnesium block into a high-temperature melt containing rare earth chloride, and heating to melt to obtain a two-phase system consisting of liquid metal magnesium and the high-temperature melt; s2, heating the two-phase system obtained in the step S1 to realize simultaneous in-situ reduction alloying and refining high-quality of the magnesium metal liquid; s3, when the reaction in the step S2 reaches the balance, magnesium chloride or metal fluoride is added into the melt to regulate and control the end point composition of the alloy; s4, after the alloy prepared in the step S3 is taken out, magnesium chloride removal and rare earth chloride addition treatment are carried out on the high-temperature melt, and the steps S1-S3 are repeated to realize continuous production. The invention can prepare high-quality multi-element rare earth magnesium alloy by using rare earth chloride and metal magnesium as raw materials under relatively simple process conditions, and realizes accurate control of alloy end-point components. |
