Furnaces of this type have a movable bottom (car). The car goes out of the furnace and may be loaded or unloaded with treated parts.
The heating method may be either electric resistance or fuel/gas.
Car bottom furnaces are suitable for various heat treatment operations of large and heavy parts.
Furnaces of this type have a movable vertically heating bell and a stationary bottom with the treated parts.
The heating method may be either electric resistance or fuel/gas.
Bell type furnaces are suitable for coiled strip annealing and other heat treatments including operations in controllable atmosphere.
Furnaces of this type are used for heat treatment of shaft like parts (generator rotors, steam turbine rotors) which are loaded vertically through the top of the furnace.
The heating method may be either electric resistance or fuel/gas.

Furnaces of this type have a mesh belt conveyor moving through a long tube like furnace.
The heating method may be either electric (resistance or induction) or fuel/gas.
Belt furnaces are suitable for heat treatment of relatively small parts.
Furnaces of this type have heat resistant steel rollers moving the parts through a long tube like furnace.
The heating method may be either electric or fuel/gas.
Roller furnaces are suitable for heat treatment of sheets, tubes and other long parts.
Furnaces of this type have a pusher located at the furnace end and moving the parts through the furnace.
The heating method may be either electric or fuel/gas.
Pusher furnaces are generally used for heating parts before hot deformation.
Coled rolled strip in uncoiled state passes through the long tube like or looped furnace with controlled reducing atmospere (commonly a mixture of Hydrogen and Nitrogen) preventing oxidation of the steel surface..
The heating method may be either electric or fuel/gas.
