Boogie hearth furnaces with radiation heating for annealing and hardening of larger parts, for example heavy cast parts or tool steel dies to temperatures between 500 °C and 1100 °C.
The boogie can be loaded outside the furnace.
When the design includes an electro-hydraulic lift door and a motorized boogie, the furnace can be opened while hot and the load can be removed or cooling or quenching.
When several boogies are used together with a second door or boogie transfer system, one boogie can be loaded outside the furnace while the other boogie is in the furnace.
This shortens process times and the residual energy of the furnace can be used when the new charge is heated.
For ceramic annealing temperature range is up to 1500 °C.

BOOGIE HEARTH FURNACES FROM 600°C TO 1200 °C

For annealing and hardening of large parts, for example, heavy cast parts or tool steel, at temperatures between 800 ° C and 1100 ° C

• The bogie can be loaded outside the furnace. Oven can also be opened hot and moved out the goods for cooling or quenching.
• Tmax 600 ° C, 900 ° C or 1180 ° C
• Double-walled housing with rear ventilation, provides low shell temperature
• Three-sided or four-sided heating on sidewalls and boogie provide optimum temperature uniformity
• Free radiation heating elements on support tubes or groves provide long service life of the heating wire
