T max. 1300 °C
- 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 consumption, 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
Options:
- 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 ped- al 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
