Abstract

The invention provides an aluminum melt purifying, degassing and refining system which comprises a case body, a compressed air source, a motor, a rotor, a flowing channel, an inert gas source and a control system, wherein the case body is used for storing molten aluminum, the compressed air source is connected with the case body, the motor is arranged at the bottom of the case body, the rotor and the flowing channel are arranged in a lower layer of the case body, the inert gas source is connected with the rotor, the motor is connected with the rotor, the control system comprises a main control unit, a preheating control unit, a gas detection unit, a flowing channel liquid level detection unit, a case body solution detection unit and a vacuum negative-pressure control unit, and the motor, the preheating control unit, the gas detection unit, the flowing channel liquid level detection unit, the case body solution detection unit and the vacuum negative-pressure control unit are connected with the main control unit. According to the aluminum melt purifying, degassing and refining system, the full automatic control on on-line degassing during aluminum melting is realized, the dehydrogenation efficiency is effectively improved, the impurity removing effect is good, the molten aluminum can be refined and purified in a complete vacuum state, the dehydrogenation requirements of various alloys can be freely changed, and the metal loss is greatly reduced.

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...
