Hot Roller Type Vacuum Heat Treatment Furnace FHHn series

Hot Roller Type Vacuum Heat Treatment Furnace

fhhn Series

FHH series are used for various purposes, such as tempering, sintering, brazing of various types of metal.

 

features

  • Adopting hot roller carry system, chamber configuration can be multiplied by combining each unitized chambers.
  • System configuration is selectable depending on process and throughput, such as preparation chamber(vacuum/atmosphere),preheating chamber(operation 500ºC),heating chamber(operation 1150ºC), cooling chamber.
  • Adopting double gate valve, each chamber is completely isolated. A vacuum/atmosphere is completely isolated.
  • Units can be added depending on process and throughput.
  • Inline process is possible, as below.“Loading→Heating 1→Cooling 1→Heating 2→Cooling 2→Unloading”.
  • Adopting six sectional temperature control system heater(option), temperature uniformity can be 1150ºC±3ºC.

Applications

  • Vacuum heat treatment : Heat treatment of various metals, brazing.
  • Sintering : Magnet.
