Using Physical Modeling to Optimize the Aluminium Refining Process

Original language description

Concern for the environment and rational management of resources requires the devel-opment of recoverable methods of obtaining metallic materials. This also applies to the productionof aluminium and its alloys. The quality requirements of the market drive aluminium producersto use effective refining methods, and one of the most commonly used is blowing an inert gas intoliquid aluminium via a rotating impeller. The efficiency and cost of this treatment depends largelyon the application of the correct ratios between the basic parameters of the process, which are theflow rate of the inert gas, the speed of the rotor and the duration of the process. Determining theseratios in production conditions is expensive and difficult. This article presents the results of researchaimed at determining the optimal ratio of the inert gas flow rate to the rotary impeller speed, usingphysical modeling techniques for the rotor as used in industrial conditions. The tests were carriedout for rotary impeller speeds from 150 to 550 rpm and gas flow rates of 12, 17 and 22 dm3/min. Theresearch was carried out on a 1:1 scale physical model, and the results, in the form of visualization ofthe degree of gas-bubble dispersion, were assessed on the basis of the five typical dispersion patterns.The removal of oxygen from water was carried out analogously to the process of removing hydrogenfrom aluminium. The curves of the rate of oxygen removal from the model liquid were determined,showing the course of oxygen reduction during refining with the same inert gas flows and rotorspeeds mentioned above.
