Problems solved by technology

[0008] In view of the fact that a large amount of aluminum slag is generated as waste from the production of aluminum or aluminum recycling, there is a real need for a new and appropriate recycling technology for aluminum slag, but so far, no treatment has been found for aluminum slag. Effective technology, therefore, generally used ones cannot meet the needs of users in actual use

Abstract

The invention relates to a radiofrequency plasma synthetic method for extracting alumina from aluminum residues. The method is characterized in that a thermal plasma technology is used for constructing a radiofrequency plasma synthesis apparatus as a high-temperature heat source, through processing of the thermal plasma and high temperature purifying of the aluminum residues, thereby the alumina is extracted from the aluminum residues to obtain the alumina ceramic powder, at the same time, the aluminum residues can be processed, alumina is produced, and the aluminum residues can be transited to merchantable products. The radiofrequency plasma synthesis apparatus comprises a powder feeder, a radio frequency generator, a thermal plasma source, a reaction chamber, a powder collection unit and a vacuum pump.

Description

technical field [0001] The present invention relates to a radio frequency plasma synthesis method, in particular to a method for extracting alumina from aluminum slag through thermal plasma treatment and high-temperature purification of aluminum slag to obtain alumina ceramic powder, especially referring to simultaneous processing of aluminum slag and production of alumina ceramic powder. Aluminum, a method of converting aluminum dross into a salable product. Background technique [0002] Generally, the process of recycling aluminum from aluminum scrap (Aluminiumscrap), such as Image 6 shown. During aluminum metallurgy (Aluminummetallurgy), molten aluminum (Moltenaluminum) and fine particles (Fineparticles) are generated, the molten aluminum is cast (Cast) in the mold to obtain aluminum ingots (Ingot) or alloys (Alloy), and when the molten metal surface and the furnace When the internal air reacts, dross will be produced; and the fine particles are collected by the air pol...
