Refining of liquid aluminium by blowing with an inert gas is one of the most effective methods of purifying liquid metal from hydrogen and non-metallic inclusions. In order to improve the efficiency of this process, it is necessary to develop a rotor design. The study compares rotors designed and their usefulness. For this purpose, the theoretical number of nozzles, the amount of gas per nozzle and the gas bubble radius were calculated.
