Product Description:
In-Line Degassing Launder Type In-line Degassing in-line rotary degassing equipment for Liquid aluminium degassing fluxing
The LDU Launder Type In-line Rotory Degassing Unit is installed
between the furnace and the casting machine along with the length
of the launder. The degassing area is divided into several stages
by using baffles to realize multi-stage online degassing and
improve degassing efficiency. The number of installed rotors is
determined by the flow rate and quality of the molten aluminium.
Features:
◆ High degassing efficiency, up to 40%. By using multi-zone
continuous degassing increases the contact area and time between
bubbles and molten aluminium. The box body is sealed as a whole to
ensure that on the top there will be an inert space over the molten
aluminium surface during casting, to prevent the oxidation of the
molten aluminium from producing more oxide slags, to prevent
secondary pollution, and to improve the degassing efficiency
◆ Using the launder to degas, the residual molten aluminium is
less, and reducing the loss of metal. The maintenance cost is low,
and the launder replacement is convenient and fast.
◆ Convenient for the quick changeover of alloys. There is no
heating device and no deep box, so at the end of each casting, most
of the degassed molten aluminium is made into products. And the
leaving molten aluminium in the degassing tank can be easily
cleaned up, which is convenient for the quick changeover of alloys
◆ Especially suitable for semi-continuous casting lines such as
cast bar and recycled aluminium ingot production. Alloys are
changed frequently in this casting process and high levels of
hydrogen removal are not required.
