ELTERMA S.A. Roller hearth furnaces can be designed to transport large loads directly on the furnace rollers or for smaller loads can be carried in heat resistant work baskets or trays.
The rollers are driven via a system of roller chains linked to an inverter driven motorized gearbox, which gives a smooth constant drive to the rollers.

Roller hearth furnaces systems guarantee minimal surface distortion after quenching, particularly important to the bearing industry where ELTERMA S.A. have supplied a number of these lines.

Main advantages of ELTERMA S.A. Roller Hearth furnaces are:

  • Multi-zones heating system in order to provide the required temperature gradient through the furnace
  • Close control of roller hearth drive system in the furnace ensures smooth even transport of the load or basket through the furnace
  • Full control de-carbonization level of the load via close atmosphere control
  • Efficient work loading and unloading systems.
