High-Quality VKN Pre-Vacuum Nitriding Furnace from China Suppliers and Factory for Enhanced Metal Treatment
Characteristic
01Muffle tank + pre-vacuum system double isolation of oxygen and impurities, to ensure the surface finish of the workpiece, to achieve zero oxidation tempering.
Equipped with hydrogen probe and mass flow meter (MFC) to accurately control the proportion of NH₃, N₂, CO₂ and other gases, combined with nitrogen potential (KN value) closed-loop feedback system, to realize the precise control of the permeation layer thickness and phase structure.
High quality heat-resistant alloy Muffle tank (Inconel 600), can quickly adapt to gas nitriding, nitrogen carburizing (soft nitriding), post-oxidation, tempering and other process switching, theoretical life of more than 8 years.
Built-in high-speed turbine fan and baffle, forced air flow multi-direction circulation, to ensure the same nitriding rate of each part of the processed parts.
Exhaust gas is discharged after treatment by the combustion device, which meets the requirements of environmental protection; The equipment is also equipped with multiple pressure relief protection (pressure sensor, safety valve, manual pressure relief valve) to ensure safe operation.
Integrated PLC, with program controller or computer interface, touch screen, recorder, real-time monitoring furnace vacuum, temperature, nitrogen potential, pressure, support remote fault diagnosis and process tracing.
The furnace door can be opened vertically, which not only saves space, opens and closes efficiently, but also fits perfectly with the automatic production line, and can be seamlessly integrated into the automatic production process, effectively improving the overall production efficiency.
The equipment provides two types of horizontal type and well type for you to choose flexibly to meet the diversified production needs.

Frequently Asked Questions
FAQZero oxidation tempering is achieved through the double isolation of oxygen and impurities using a high-performance Muffle tank combined with a pre-vacuum system, ensuring a high-quality surface finish on the workpiece.
The Muffle tank is constructed from a high-quality heat-resistant alloy (Inconel 600). It is designed to adapt quickly to process switching (such as gas nitriding, soft nitriding, post-oxidation, and tempering) and has a theoretical service life of more than 8 years.
Uniformity is maintained by a built-in high-speed turbine fan and baffle system that forces multi-direction air circulation, ensuring a consistent nitriding rate throughout the entire chamber.
Yes. While standard models range from VKN-200 to VKN-4000, we fully support the customization of the effective working area size, shape, and other operational parameters to meet your specific production requirements.
The system treats exhaust gas using an integrated combustion device before discharge to meet environmental regulations. For safety, it features multiple pressure relief protections, including pressure sensors, safety valves, and manual pressure relief valves.
