Embodiment 1
[0013] Magnesium rare earth alloy refining flux composition (mass percentage): 40% calcium chloride (CaCl 2 ), 20% potassium chloride (KCl), 10% sodium chloride (NaCl), 15% barium chloride (BaCl 2 ), 2% calcium fluoride (CaF 2 ), 3% cryolite (Na 3 AlF 6 ), 10% rare earth chloride (RECl 3 ).
[0014] The production method of the magnesium rare earth alloy refining flux is as follows: after the crucible is heated to about 350 ° C, potassium chloride, sodium chloride, calcium chloride, barium chloride and cryolite are added, and after the temperature is partially melted, calcium fluoride is added , heated up to about 770°C, stirred evenly, and poured into blocks. After crushing, put it into a ball mill and grind it into powder, and sieve it with a No. 20 sieve. Then rare earth chloride was added and mixed with a ball mill. Prepared flux should be put into airtight container for standby.

[0017] Magnesium rare earth alloy refining flux composition (mass percentage): 20% calcium chloride (CaCl 2 ), 10% potassium chloride (KCl), 20% sodium chloride (NaCl), 25% barium chloride (BaCl 2 ), 5% calcium fluoride (CaF 2 ), 10% cryolite (Na 3 AlF 6 ), 10% rare earth fluoride (REF 3 ).
[0018] The production method of the magnesium rare earth alloy refining flux is as follows: after the crucible is heated to about 400 ° C, potassium chloride, sodium chloride, calcium chloride, barium chloride and cryolite are added, and after the temperature is partially melted, calcium fluoride is added , heated up to about 760°C, stirred evenly, and poured into blocks. After crushing, put it into a ball mill and grind it into powder, and sieve it with a No. 30 sieve. Then rare earth fluoride is added and mixed with a ball mill. Prepared flux should be put into airtight container for standby.

[0021] Magnesium rare earth alloy refining flux composition (mass percentage): 30% calcium chloride (CaCl 2 ), 25% potassium chloride (KCl), 15% sodium chloride (NaCl), 20% barium chloride (BaCl 2 ), 4% calcium fluoride (CaF 2 ), 3% cryolite (Na 3 AlF 6 ), 3% rare earth carbonate (RE 2 (CO 3 ) 3 ).
[0022] The production method of the magnesium rare earth alloy refining flux is as follows: after the crucible is heated to about 300 °C, potassium chloride, sodium chloride, calcium chloride, barium chloride and cryolite are added, and after the temperature is partially melted, calcium fluoride is added , heated up to about 780°C, stirred evenly, and poured into blocks. After crushing, put it into a ball mill and grind it into powder, and sieve it with a No. 40 sieve. Then rare earth carbonate is added and mixed with a ball mill. Prepared flux should be put into airtight container for standby.
