Tempering or Annealing with a Bogie-hearth Furnace
Heat treatment has to be gentle and powerful at the same time to make processes like tempering, annealing, homogenizing and recrystallization reliable and easy. Bogie-hearth furnaces promise customers the highest quality possible if used accordingly and have a temperature range of up to 1200°C.
Bogie-hearth furnaces are useful when it comes to fine procedures like soft annealing and are delivering the best results when it comes to normalizing or stress relieving.
It’s important to understand, that in order to achieve optimal heating results, the chamber has to be insulated properly in order to keep a constant high temperature. Accuracy is the key when materials have to be annealed or tempered, therefore the sidewalls of the furnace chamber have been equipped with a high-temperature fiber insulation and mineral wool. This makes Bogie-hearth furnaces not only accurate but also easy to maintain.
At its core, so to speak, and the necessity for the entire cooling process, the furnace combines one or many circulation fans and motor-driven dampers. They are situated on the roof.
Anatomy of a Bogie-hearth furnace
In order to assure safety and a long lifetime of the furnace, the motor-driven bottom is not only built up by insulating but also features fire-resistant bricks. Another important feature, which guarantees safety is the pneumatic sealing between the heating chamber and its bottom. Since the door can be lifted and controlled by a pneumatic system, it helps automatize the process and speed up procedures.
Other benefits of the bogie-hearth furnace are the high rate of efficiency and the possibility to save energy, depending on an either fully electrical or gas power mode. The delivered product will always be high in quality and meet even the highest standards.
