Description

technical field [0001] The invention relates to the technical field of aluminum melting and casting, in particular to an aluminum melt purification and degassing refining system. Background technique [0002] In order to obtain good aluminum melt quality and produce high-quality aluminum processed products, the basic impurities (hydrogen, slag or alkali metal) in the melt must be extracted during the aluminum smelting process. At present, the most direct technology in this field is to inject an inert gas source into the bottom of the aluminum liquid, mix and contact with the aluminum liquid through stirring and refining, and remove these harmful impurities during the floating process of the inert gas. [0003] Traditional on-line dehydrogenation equipment, such as SNIF in the United States, Alpur in France, Pyrotek in the United States and other major on-line dehydrogenation processing devices, are currently widely used in various fields of aluminum melts. Insert one or two...
