Application:
Pre-vacuum nitriding pit furnace is widely used in heat treatment processes such as nitriding, nitrocarburizing (soft nitriding), annealingunder protective atmosphere, tempering, etc.
Description:
The equipment is composed of furnace shell, lining, heating element, furnace tank, lid, air distribution, pre-vacuum system, electrical control system, etc.
Equipment Features:
1. The advanced heat treatment and atmosphere circulation technologies ensure ideal furnace temperature and homogeneous atmosphere.
The pre-vacuum technique reduces the time of atmosphere replacement and pre-oxidation of workpiece surface, increases production efficiency, reduces nitrogen consumption, improves surface quality and nitriding quality of the workpiece.
2. Direct and indirect cooling systems can meet the cooling requirements of different workpieces.
Cooling under protective atmosphere with adjustable cooling speed effectively prevents oxidation and deformation of workpiece.
3. A nitriding expert systemmonitors furnace atmosphere, ammonia, hydrogen and oxygen indexes, provides reliable Kn value, and ensures consistent product quality.
The pre- and post-oxidation technique of the expert system effectively improves nitriding speed and quality.
4. Under emergency, the expert system automatically opens nitrogen safety valve to release inflammable and explosive gases released during nitriding, and ensures safe operation.
5. Reliable electrical system enables automation of furnace heating, operation control, heat treatment process control; extended functions can be achieved with optional function modules.
