VERTICAL HIGH TEMPERATURE VACUUM PIT TYPE FURNACE TYPE C / TYPE CE Vertical vacuum pit furnace with round hot zone for high temperature processes like hardening, brazing, sintering, etc. type C: model with hot zone insulation made of graphite type CE: model with hot zone insulation made of molybdenum + stainless steel The vertical vacuum pit furnace is often used for long narrow parts like large centerline components. Loading of the furnace from the top. DETAILED DESCRIPTION The vacuum pit type furnace is designed on the ""cold-wall principle"". The cylindrical outer casing is a vertical construction, double-walled and water-cooled. Thermal strain is hereby excluded as no measurable temperature will be transferred to the outside wall. Inside the casing the following components are located: hot zone, heat exchanger, high capacity radial fan with electric motor and the gas ducts. Outside the casing the vacuum pump station, the transformers and the switchboard are installed. This compact design guarantees an extremely low need of space. The layout will be adapted widely with the local facilities. The maintenance friendly design is leading to an easy access to all elements and components of the furnace. Loading and unloading of the furnace is done from the topt. The swivelling furnace door will be secured with the furnace casing hydraulically / electrically against overpressure after loading. The required time-/temperature cycle is running fully automatically afterwards. SCHMETZ vertical vacuum pit type furnace are operated in inhouse or commercial hardening shops and also for high temperature brazing applications as example.
