Refining refining agent commonly used solid or gas refining agent. Solid refining agent generally chloride mainly, but also for hexachloroethane instead of chlorine salt refining agent. Early use of active chlorine as a strong gas refining agent, purification effect is good aluminum products processing factories, but serious environmental pollution, so the development of nitrogen - chlorine mixed gas, an inert gas, and three gas (N2, Cl2, CO) refining agent, better. To ensure the refining effect, refinery gases oxygen and moisture content should generally be less than 0.03%, respectively (by volume) and 0.3 g / m3. Dynamic vacuum degassing method also has good outgassing and sodium removal effect.
