Fluidheat Fluidised Bed Furnaces

Principle

Fluidisation is the technique of making a bed of small, dry particles (e.g. Aluminium Oxide) behave like a liquid.  This is achieved by feeding a supporting gas up through the bed of particles.  The supporting gas provides the protective atmosphere for heat treatment of the work immersed in the bed.  The heating is by gas or electricity.

Fluidheat Furnace - The Alternative to Vacuum

In some applications, such as high quality plastic components, an extremely good surface finish is required.  Then, nothing can beat a good vacuum heat treatment, provided that both hardening and tempering are done in vacuum.

However, in most cases the surface finish obtained by a Fluidheat treatment meets the requirement of the application.  Compared to vacuum hardening the Fluidheat method offers the following advantages:

• Considerably lower investment cost
• Shorter cycle time - higher productivity
• Equal or lower distortion
• Tools can be individually treated since they can be reached and manipulated at any time during the heat treatment cycle
• Better hardened structure due to more rapid quenching
• Lower maintenance costs
• Versatility - a large number of different thermochemical treatments such as nitrocarburising, carbonitriding, carburising and nitriding can be done in the same unit on the same day!
