Fizikalni model procesa rafinacije aluminija u reaktoru URC-7000

The paper presents short characteristics of the most frequently used reactors for the continuous refining of aluminium and its alloys. Refining depends on the flow rate of refining gas. It influences the shape and size of gas bubbles. So the physical model was created to determine the level of gas bubble dispersion in liquids. Schemes of gas dispersion in liquid metal were presented taking into consideration that the gas flow rate is changing from 2 to 30 dm3/min. The range selection of the flow rate of refining gas value for five patterns of the dispersion (no dispersion, minimum, intimate, uniform and overdispersion) was also done.
Članak daje kratke karakteristike najčešće rabljenih reaktora za kontinuiranu rafinaciju aluminija i njihovih legura. Rafinacija ovisi o brzini struje plina za rafinaciju. Utjecajni su oblik i dimenzije plinskih mjehura. Fizikalni model je utemeljen za određivanje razine disperzije plinskih mjehura u tekućinama. Shema disperzije plina u tekućem metalu predstavljena je uzimajući u obzir promjene brzina struje plina za rafinaciju vrijedeće za pet stupnjeva disperzije (bez disperzije, minimalna, očekivana, ujednačena i pojačana disperzija).
