NITRIDING/NITROCARBURIZING SIMPLIFIED

The Nitrex process control system is a product of extensive R&D in process automation and enables accurate process execution and consistency of results. The entire nitriding /nitrocarburizing process is executed in an automatic, self-adjusting and operator independent manner.

This expert system monitors and responds to changes in nitriding conditions by regulating the following parameters and operating functions:

Furnace heating functions such as process temperature, and overheat control with automatic emergency procedures
Atmosphere composition and flow for a cycle
Nitriding atmosphere ratios
Nitriding Potential KN (dissociation rate, for customer defined cycles)
Temperature for each process stage
Gas pressure inside the retort
Gas recirculation
Execution of the cooling stage and shutdown
Cooling water
Process safety features

ENJOY PEACE OF MIND

With our ‘set & forget’ process, the user selects the desired recipe from a library of researched and tested recipes and initiates a process. From there, all stages of the nitriding cycle (e.g., purge, heat, process control, and cool) are automatically carried out sequentially in one uninterrupted cycle, without further operator intervention. This set-up provides a high degree of accuracy in process execution, contributing to consistency in nitriding / nitrocarburizing results.
