Pit Type Nitriding Furnace for Gas Nitriding, Nitrocarburizing, Pre-Oxidation, Post-Oxidation and Oxynitriding

We integrate a high-precision Partial Pressure Control System. By introducing ultra-high purity Argon or Nitrogen gas during the heating cycle, we suppress the vapor pressure of volatile alloying elements, preventing element depletion and preserving material chemistry.

For sintering applications (MIM/PM), we utilize directional gas flow paired with a multi-stage wax/binder collection trap. Binders are cleanly swept away before they can condense on the graphite insulation or heating elements, significantly extending element lifespan and reducing maintenance downtime.

Yes. Our Vacuum Oil Quenching systems feature a high-speed, heavy-duty automated internal elevator and transfer mechanism. The complete transition from the heating chamber to total oil immersion takes less than 10 seconds, ensuring maximum hardness and precise microstructure transformation for critical steels.

Our standard pumping configurations (Roots Pumps, and Diffusion Pumps) achieve an ultimate clean vacuum of 10^-3 Pa to 10^-4 Pa. The system logic is programmed with intelligent vacuum interlocking to automatically manage outgassing phases without crashing the main pumps.

The furnace reaches a maximum temperature of 1300 degrees and achieves an ultimate vacuum of 5.0 * 10^-1 Pa.
