  Switch off the heating unit after degassing unit heating is completed. Guide inert gas into the rotor and release molten aluminum into the box when the heater temperature is closed to molten aluminum temperature.

  Check the sealing between inlet/outlet and launder.

  Check the cone located in heat protection draining in the bottom.

  Check the molten aluminum temperature (min 720°C). Make the height of molten aluminum be away from the launder bottom at 3cm for observing the molten aluminum going into thebox.

  The operator shall wear protective clothes to close the cover. The slag on the surface can be skimmed through the degassing unit when the molten aluminum flows into the box.

  Start production when the temperature is up to 780°C. Close degassing unit outlet for heating preservation.

  Molten aluminum can be retained in the box with setting temperature during the heat preservation phase but with no molten aluminum handling.

  Guide inert gases into the rotor to prevent air outlet blocking by molten aluminum.

  Switch on the heater as soon as molten aluminum flow into the box is completed and set heat preservation parameters.

  Starting the heating system, control the temperature of the molten aluminum, monitor the gas flow rate, and the speed of the rotor is changed from the heat preservation stage to the processing stage. At the same time, the inert gas flow into the rotor increases, and the gas flow rate is changed from the preservation stage to the processing stage.

  The operator sets the molten aluminum heating temperature and maintains a stable degassing unit working condition.
