Description

 

The impeller is used for the finaltreatment of a container filled with liquid aluminium, to bring impurities and inclusions in the melt to the surface by adding argon,nitrogen or a chlorine-gas-mixture and toreduce the dissolved hydrogen at the same time.

According to the customer’s needs the machine can be designed for rotation or forlongitudinal or cross-wise transport of one or several crucibles.
