Research on Water Simulation Experiment of Spinning Rotor Degassing Process of Al-alloy
The practical purification process of the Al-alloy was simulated based on CO2-NaOH system. The gas flow rate and rotational speed were determined as the main influencing factors of the rotating impeller degassing using primary orthogonal water simulation test. The quadric regression equation of the gas flow rate, rotational speed and blowing time were obtained by means of orthogonal test. Furthermore, the optimal processing parameters of rotating impeller degassing process were defined,namely rotational speed v=374 r/min, the gas flow rate q=1.8 L/min.
