Bogie hearth
furnaces

For heating very large parts

The bogie furnace is made up of a main structure base for heating very large parts (such as: metal structures, heavy mechanical parts, connectors, flanges and curves, etc) or pieces in bulk that cannot be treated with other types of furnaces.

The bogie furnace is constituted of an insulated stationary structure, electrically heated or gas fired by a mobile base (bogie), which carries the material to be treated.  The bogie moves into the furnace by means of rails, racks or metal cables controlled by a gear motor.

Double bogie furnaces with double doors are usually used to reduce the loading and unloading downtimes.

The bogie furnaces normally use self heat recovery burners and recuperators on combustion fumes capable of compensating, in part, energy losses that are typical of discontinuous furnaces.
