Matter cause crude magnesium (Crystalline Magnesium) volume it is big, it is loose, be not easy keeping, storage, transport, and these metal impurities can with magnesium formed merchant's method
Electrochemical corrosion occurs for Buddhist nun's battery, and magnesium plays anode, and the metal impurities such as iron and nickel play cathodic process, accelerate the corrosion of magnesium.Cause
This crude magnesium, which must refine, can be only achieved the requirement that industry directly uses.
Vacuum breaker (air vacuum breaker) takes out crystallizer after production of magnesium by pidgeonprocess obtains Crystalline Magnesium, by Crystalline Magnesium from crystallizer
Refining plant is sent into abjection.Refining solvent is added in refining process first in crucible, Crystalline Magnesium is reloaded into, in 750 DEG C of temperature
Lower heating and melting is slowly added into Crystalline Magnesium and melting solvent, when the magnesium in crucible reaches the height of crucible dischargeable capacity, makes earthenware
Magnesium liquid temperature is maintained at 710 DEG C in crucible, refining solvent is then added, while being stirred (stirring while adding), mixing time is about
10 minutes, then temperature is risen to 740 DEG C (or 720 DEG C), and stand 5 ~ 10 minutes, protected after being cooled to 710 DEG C to magnesium liquid
Temperature completes the refining of crude magnesium.Magnesium burns in refining process, need to spread the burning that covering flux prevents magnesium, prevent the oxidation of magnesium
Loss.
