Flexibility of Fluidised
Bed Furnaces
Any temperature (ambient to 1200°C) + Any heat treatment atmosphere = All heat
treatment processes in single furnace
Rapid Atmosphere Exchange
Quick Startup and Shutdown
Hardening & Tempering of Components & Tooling |
low distortion due to uniform heat transfer
high quality surface finish
consistent hardness
short cycle time, high productivity
|



 |
Carburising and Carbonitriding
higher rate of carbon penetration
classic boost/diffuse carburising
consistent hardness & case depth
high temperature carburising upto 1080ºC
precise control of shallow case depths
absence of sub-surface oxidation
improved fatigue strength
good case uniformity in holes & gearteeth roots
precise control over hardness profile
|
Nitrocarburising and Nitriding
shallow case Nitrocarburising as in proprietary salt bath processes.
also deep case Nitrocarburising without surface chemical attack likely in salt baths.
clean & non toxic process
deep case Nitriding, shorter cycle time
easy control of the Nitriding potential
processing from 450ºC to 700ºC
"NIL TO FULL" surface porosity control
mid cycle steam injection for adherent oxide layer for corrosion resistance
Oxynitriding capability
components are taken out after Nitriding or Nitrocarburising is over. No long cooling cycle as in retort furnaces
for Nitriding steels, other alloy steels, low carbon steels, tool steels, stainless steels, irons & sintered parts.
