Application of ultrasonic and rotary electromagnetic field in aluminium melting refining

Abstract

The invention discloses a physical synthesis field method of an ultrasonic and rotary electromagnetic field, which is used for smelting, purifying and dehydrogenating metal, removing metal impurities and non-metallic inclusions and improving metal crystal refinement so as to produce high-purity metal. In an impurity removing process, dielectric is not added, chlorine which is used for dehydrogenation is not communicated or fluorine-containing substances are added. In an aluminium melting refining purification experiment, the efficiency of the method is confirmed, and the device of the method is the ultrasonic and rotary electromagnetic field. The method is a synthetic physical field technology of a micro-explosion technology and a multidimensional layered continuous spiral line transient reversing vortex technology and is characterized in that the controllable layered large dispersity, the strong potential energy, the small-diameter bubble compression field and the gas explosion body trapping are used in metal (aluminum) liquid, and the functional effects of molecular collision, resonance, autorotation, glomeration, and the like are used. The method has high impurity removing speed, good effect and no pollution, saves energy and does not have an external publication report in the metal melting refining purification experiment.

Description

technical field [0001] The invention belongs to the category of metal refining and purification in high-temperature metallurgical smelting. [0002] Pyrometallurgical technology, including the refining and purification process of non-ferrous metals and steel, can also be called {slagging} technology, the common purpose of which is to remove harmful metal impurities, gases and non-metallic inclusions melted in the liquid metal melt etc. to precipitate or transfer to the slag to achieve the required purity, purity and the best shape of its microstructure (crystal). Background technique [0003] At present, in the non-ferrous metal aluminum smelting industry, the production processes such as impurity removal, purification, refining and grain refinement of high-quality aluminum and high-purity aluminum have not changed much over the years. Although there are many kinds of technical methods adopted at home and abroad, they have affected aluminum smelting enterprises to varying d...
