Therefore, the crude magnesium must be refined to meet the requirements of direct industrial use.
And (3) after the magnesium is smelted by the Pidgeon process to obtain crystalline magnesium, breaking vacuum (breaking vacuum by air), taking out the crystallizer, removing the crystalline magnesium from the crystallizer, and sending the crystalline magnesium into a refining workshop. In the refining process, firstly adding a refining solvent into a crucible, then adding crystalline magnesium, heating and melting at 750 ℃, slowly adding crystalline magnesium and a smelting solvent, keeping the temperature of magnesium liquid in the crucible at 710 ℃ when the magnesium in the crucible reaches the effective volume of the crucible, then adding the refining solvent, stirring (stirring while adding) for about 10 minutes, then raising the temperature to 740 ℃ (or 720 ℃), standing for 5-10 minutes, cooling the magnesium liquid to 710 ℃, and then preserving the heat to finish refining of crude magnesium. The magnesium burns during refining, and the solvent needs to be spread to prevent the burning of the magnesium and prevent the oxidation loss of the magnesium.
