The separation between vacuum and atmosphere is made on the inside of the coil in our vacuum furnace construction.
There are the following advantages compared to a furnace construction completely in a vacuum:
Like our crucible furnaces, our vacuum furnaces are designed as a solid welded construction. All sizes have generously dimensioned yokes made of transformer sheet metal that guide the magnetic lines outside the coil. As a result, the coil cage, in contrast to yokeless constructions, can be designed as a closed welded steel construction.
The exposure of the furnace operator to the magnetic field is reduced to a minimum.
The furnace coils have a special coating. A special coil profile ensures a secure fit of the inserted seal. Coil, furnace head and furnace bottom are precisely matched to one another in order to achieve a low leak rate over a long period of time.
During the construction, special emphasis was placed on good accessibility for maintenance work.
