Cooling fan for shorter process cycles

W 1000/G - W 10000

For annealing and hardening of large parts, like heavy cast parts or tool steel dies to temperatures between 800 °C and 1200 °C, we recommend our bogie hearth furnaces with radiation heating. The bogie can be conveniently loaded outside the furnace. With a second door or bogie-transfer system, one bogie can be charged outside the furnace while the other bogie is in the furnace. This way, turnaround time between process cycles will be reduced substantially.

Maximum temperatures of 900 °C or 1280 °C
Double-walled housing with rear ventilation, provides low shell temperatures
Swing door hinged on the right side
Heating from five sides (four sides and bogie) provides for a uniform temperature distribution
Automatic power connection to the bogie when moved into the furnace
Heating elements mounted on support tubes provide for free radiation and long service life
Floor heating protected by SiC tiles on the bogie providing level stacking surface
Multi-layer insulation consisting of lightweight refractory bricks backed by microporus silica insulation
Self-supporting roof arch
Bogie on rails incl. rails in front of the furnace for charging
Adjustable air inlet damper
Manual vapor vent on the furnace roof

Additional Equipment

Powerful direct gas heating
Support grid made of heat-resistant cast steel for optimum weight distribution on the bogie for use up to 1100 °C
Second door in rear wall for use of second bogie
Lift-door instead of swing door including heat shield for opening while hot
Heat shield ”filler bogie” when the bogie is removed at high temperatures
Second bogie
Electrical bogie drive
Freely maneuverable bogie on Pevolon casters when using light charge weights
Cooling fan for shorter process times
Automatic control of exhaust air dampers
Multiple zone control for optimum temperature uniformity according to DIN 17052-1 up to ΔT 10 K
Alternative connected power
Special sizes up to 20,000 liters
Fixed hearth and movable furnace (envelope concept) for heavy charges up to 100 tons
