Modelsko istraživanje desorpcije vodika iz rastaljenog aluminija i njegovih legura

The refining process is essential for the removing undesirable hydrogen and harmful impurities from liquid aluminium and its alloys. Physical modelling allows to observe the level of refining gas dispersion in the liquid aluminium. Test stand for physical modelling of the barbotage process of aluminum for the bath reactor (URO-200) and continuous reactor (URC-7000) were built. Measurements of the oxygen removal from water were carried out as analogy of the hydrogen desorption process from liquid aluminium. In the research the distilled water saturated with the compressed oxygen was used. The level of water saturation with oxygen and then oxygen desorption from water was reached by means of the dissolved oxygen meter Elmetron CO-401.Proces rafiniranja je vrlo značajan zbog odstranjivanja nepoželjnog vodika i drugih štetnih nečistoća iz rastaljenog aluminija. Fizikalno modeliranje dopušta da se uoči razina disperzije rafiniranog plina u tekućem aluminiju. Izrađen je pristup za fizikalno modeliranje procesa rafiniranja aluminija. Mjerenja odstranjivanja kisika iz vode su provedena po analogiji procesa desorpcije vodika iz tekućeg aluminija. U istraživanju je korištena destilirana voda zasićena komprimiranim kisikom. Razina zasićenosti kisikom i desorpcija kisika iz vode je postignuta pomoću okigenometra Elmetron CO-401
