For annealing and hardening of larger parts, for example heavy cast parts or tool steel dies to temperatures between 800 °C and 1100 °C, we recommend our bogie hearth furnaces with radiation heating. The bogie can be loaded outside the furnace. When the design includes an electro-mechanical lift door and a motorized bogie, the furnace can be opened while hot and the load can be removed for cooling or quenching. When several bogies are used together with a second door or bogie transfer system, one bogie can be loaded outside the furnace while the other bogie is in the furnace. This shortens process times and the residual energy of the furnace can be used when the new charge is heated.
Tmax 900 °C or 1200 °C
Dual shell 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 optimum temperature uniformity
Bogie heating receives power via blade contacts when driven in
