DEGUSSA Heat Plant
DEGUSSA Type VSgr 150/150 High Vacuum Brazing and Heat Treatment Plant
The JAT Tenika Engine Workshop includes a Heat Treatment Shop which is equipped for both types of heat treating - localized and furnace heat treating.
JAT Tehnika Vacuum Plant "DEGUSSA Type VSgr 150/150 for High-temperature Brazing and Heat Treatment", with possibility of overpressure inert gas (N2,Ar) cooling, accommodate following airplane engine and exhaust parts heat treatments:
- gas quenching,
- stress-relief after welding,
- solution treating,
- aging-full and short cycles,
- stabilization and
- precipitation to maximum temperature of 1300 degrees C.
CFMI recommends vacuum brazing and heat treatments which, combined, have proved very satisfactory in bringing damaged power plant parts back into serviceable condition, because of advantages of vacuum as 'protective atmosphere':
- Parts free of surface oxidation
- Parts are automatically cleaned during heat treatment
- No surface decarburization
- Bright, metallic, shiny parts, i.e. parts require no further cleaning.
Today the most important application of vacuum heat treatment and brazing is used in aircraft industry and engine overhaul shops as well in nuclear industry. Materials which respond well to vacuum heat treatment include the super-alloys (heat resistant materials based on nickel, iron-nickel, and cobalt-nickel), reactive and refractory materials ( titanium), and various grades of stainless steel.
Jat Tehnika vacuum furnace is acclaimed as largest in region and one of the most modern, i.e. achieves guaranteed high temperature uniformity ±5K due all around heating with separately controllable circuits; controlled alternatively by hand or in a fully automatic manner.
