Definitions

the contact electrode and the graphite electrode can easily be removed from the vessel and used for another interchangeable vessel.
the process of the metallurgical process can thus be accelerated without increasing costs.
the radiation exposure of the ff material is significantly reduced by the arrangement of the electrodes according to the invention. Operating costs are reduced due to smaller electrode consumption.
the device is also suitable for vacuum processes and processes with protective gas cover.
