P & L Heat Treating, Inc. has purchased a pit nitriding furnace equipped with ZeroFlow technology for their Youngstown, Ohio commercial heat treat facility.
The pit nitriding furnace will accommodate a fixtured load of up to 5500 pounds (2500 kg) with a retort 1000 mm in diameter x 2000mm deep, and a clear load area of 39 inches X 78 inches. The furnace will be equipped with an Inconel retort, internal recirculation fan, sinuous loop heating elements and PLC control system.
ZeroFlow Technology
The nitriding of steel using the ZeroFlow method allows precise forming of nitrided layers with respect to the required phase structure, zone thicknesses, and hardness distribution. In controlled tests, this furnace design reduced process gas consumption using a simplified, inexpensive process adjustment and control system producing consistent, repeatable heat treatment results.
