TEMPERING AND PRE-OXIDATION OF TRANSMISSION GEARS
The lone batch-type application of high speed high precision Pyro tempering is gears for an all-wheel drive power take-off unit. These vacuum carburized and high pressure gas quenched gears, utilized a consistent loading arrangement with ample spacing for repeatable convective heating performance. Four systems performing both pre-oxidation and tempering were delivered utilizing a 40-minute cycle for a 1400 lbs gross load. The conventional process called for a 120-minute cycle time and would have involved multi-tray continuous ovens. The high speed in/out batch solution delivered maximized process flexibility, reduced floor space, reduced in-process inventory, and fewer alloy fixtures.
Conventional: 120 minutes
Pyro: 40 minutes
Why settle for less - Add the Dragon to vacuum carburizing!
