Vacuum furnace Cieffe Forni Industriali

The NCV furnaces have been constructed to satisfy the request of treating charges horizontally in alternative to the traditional pit furnaces, combining the advantages of the pit furnaces (see the containing retort in steel) with the operativeness of the chamber furnaces.

The most important innovations of the last ten years have been applied and the strongest points are:

- temperature and consequently treatment uniformity;
- the possibility to use gas heating alternatively to the electric heating which provides considerable advantages for both production and quality;
- the easiness with which the vacuum can be applied in various points of the cycle according to needs;
- the simple and maintenance-friendly sealing system;
- the process control which includes the automatic gas adjustment by means of mass-meters, with constant control of the internal pressure;
- the prearrangement for the insertion of various probes or analysers that the market offers at present.

Moreover, a high efficiency can be attributed to the rapid charge-cooling system, which works by making warm gas circulate in an external heat exchanger.
The door can be opened both sideways and vertically, thus facilitating the integration in automatic loading/unloading systems.
In the following, we will see some interesting applications.
