Modelling of Technological Parameters of Aluminium Melt Refining in the Ladle by Blowing of Inert Gas through the Rotating Impeller

The presented paper deals with the use of physical modelling to study degassing process aluminium melts in refining ladle by blowing inert gas through a rotating impeller. For purposes modelling, plexiglass model scale 1:1 is used for operating ladle. Part hollow shaft supply that equipped an impeller and two baffles. melt simulated at decrease dissolved oxygen liquid (water). This aimed evaluation laboratory experiments were obtained method modelling. Attention focused on assessment relevant parameters process—rotary speeds, volume flow rate gas, distance from bottom ladle, variant. preliminary results show optimal are achieved using F2A 190
