ICBP® Duo Innovation to replace integral quench & sealed quench furnaces

Vacuum Oil Quenching Furnace advantages :

DUO furnaces are a great alternative to sealed quench furnaces and have singificant advantages. Indeed, heat treatments are done at higher temperatures and lead to a better treatment quality as well as shorter cycles, which results in an increased productivity.

These installations are also very convenient to integrate in production and / or machining lines. Their design limits heat losses, reduces CO2 emissions and cancels the risk of fire hazard since no flames are generated thanks to the use of vacuum. Moreover, DUO furnaces are electrically heated.

Electric heating has several other advantages such as the elimination of endo gas generators, which eases maintenance and avoids additional costs. Also, this heating method significantly ereduces gas consumption and emissions since gas injections are stricly limited to the process according to the kind of treatment needed. As an example, in the case of a carburizing process, gas injections only occur in the enrichment phase as “boosts” and during the quenching phase if gas queching is relevant.

Finally, the carbon footprint of these furnaces is considerably reduced compared to sealed quench furnaces and hence allows cleaner, more efficient and more sustainable heat treatments.
