Salt-Bath Furnaces for Heat Treatment of Steel or Light Metals Electrically Heated or Gas-Fired

Salt-bath furnace TS 40/30, electrically heated Salt-bath furnace TSB 30/30, gas-fired

Salt-bath furnace TS 30/18 with preheating chamber above the salt bath and charging aid for immersion of the charge

Salt-bath furnaces offer remarkably high temperature uniformity and excellent heat transfer to the work piece. Our salt-bath furnaces TS 20/15 - TSB 90/80 are especially useful for heat-treating of metals in neutral or active salt baths. Processes such as carbonitriding (e.g. Tenifer) up to 600 °C, carburizing up to 950 °C, or bright annealing up to 1000 °C can be realized. In their standard version these salt-bath furnaces are equipped with safety technology for heat treatment of steel. As addional feature they can be equipped with extended safety technology for heat treatment of light metals.

  • Tmax 750  °C or 1000  °C in the salt bath
  • Safety technology according to EN 60519-2
  • Useful for heat treatment of steel
  • Salt bath temperature control
  • Electric (TS) all-round heating or gas heating (TSB)
  • Removable collar plate made of solid steel
  • Insulated swing-a-way lid
  • Temperature uniformity up to +/- 2 °C according to DIN 17052-1 in the salt bath
  • Over-temperature limiter with manual reset in the furnace chamber to prevent dangerous conditions for the furnace or personnel
  • Salt bath control of salt bath and furnace chamber
  • Defined application within the constraints of the operating instructions

Crucibles

  • Type P: low carbon steel and CrNi plated for carburizing, neutral salt and annealing baths up to 850  °C
  • Type C: high alloy CrNi steel for neutral salt and annealing baths up to 1000  °C and for dip brazing of Aluminium

Additional equipment

  • Exhaust gas collection at rim for connection to an exhaust system
  • Enhanced safety systems for heat treatment of aluminium and magnesium in the salt bath with second over-temperature limiter with manual reset and PLC-bath control with thermocouples in the salt bath and in the furnace chamber
  • Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control
