Purification technology for the melt body of aluminum alloy is the key for improving the quality of aluminum alloy material. The developing situation is reviewed also, such as degassing process by gassing, fixed or revolving gassing and spraying. In order to achieve the new level of purification, We improve the condition of degassing process with melt body of aluminum, adopt complicated purified technology, putting into the gas solvent and a type of technology such as canceling oxidation inclusion.
