Vertical bottom loading annealing vacuum furnace
Appointment
The bottom loading vacuum annealing furnace is designed for light annealing of tool steel, stamped steel, high speed steel, heavy duty steel, magnetic materials, stainless steel, non-ferrous metal materials and so on. In particular, for hardening under vacuum of rods, panels, long shafts and similar dimensional parts that easily deform in heat treatment.
Technical features of a vertical bottom loading vacuum annealing furnace
The furnace is vertical, single-chamber, with loading from the bottom. You can choose the mixing mechanism of the furnace hearth according to customer requirements.
Modular optimized furnace chamber, with good temperature uniformity and cooling uniformity.
The drive, lifting and lifting mechanism for the furnace hearth is made depending on the situation at the installation site.
The mechanism for raising and removing the hearth of the furnace has an automatic function to minimize errors, mixes stably and without vibration.
Heating under vacuum, Ar or H2.
