Technical specifications

  • Very robust chamber furnaces e.g. for annealing, hardening, powder carburizing and powder nitriding, preheating, forging etc.
  • Double-walled housing with rear ventilation for low outside shell temperature
  • Parallel guided swing door opening downwards (KM 10/13 – KM 70/13), with steel tray on the door as charging aid as well as door lintel, both made of stainless steel, loading height approx. 900 mm
  • From KM 110/13 manual parallel guided door up-wards opening, with counterweight, easy to open, from KM 780/13 with hydraulic lift door
  • Base frame already included in the standard scope of delivery (from KM 50/13)
  • Multi-layer insulation (lightweight refractory bricks and insulation) for low heat loss, low energy con-sumption, low electricity costs
  • 3-sided heating (from both sides and bottom) with heating wire for a uniform temperature distribution in the furnace chamber
  • Heating elements mounted on ceramic support tubes, free heat radiation into the furnace chamber, thereby energy saving and long service life of the heating elements
  • Covering of the floor heating elements by heat permeable silicon carbide plates with high mechanical strength, to protect the bottom heating
  • Sufficiently dimensioned power guarantee short heating times

  • Charging plates and grates as additional protection for the furnace bottom
  • Lateral protective cover of the heating elements through silicon carbide boards
  • Lift door with hydraulic drive, operable via foot pedal or 2-hand operation (standard from KM 780/13)
  • Automatic fresh air and exhaust air flaps, controlled via the program controller
  • Fresh air fan for forced cooling of the batch or exhaust gas discharge
  • Semi-gas-tight design with special sealing and gas connection for non-flammable protective gases
  • Gassing and hardening boxes and suitable charging aids
