NXH Horizontal Series

The heavy-duty NXH front-loading gas nitriding/nitrocarburizing furnaces provide flexibility for a wide range of applications. The specially-designed retort furnace and heating elements guarantee many years of reliable service. Other product innovations provide a faster load heating rate, excellent temperature, and nitriding uniformity.

Deploying multiple controlled heating zones ensures optimal temperature uniformity inside the retort, typically +/-5°C (9°F) or better. NXH furnaces are designed for fast heating rates and uniform temperature throughout the load.

FEATURES & BENEFITS

  • Inconel 600 (refractory steel) retort and racking for long service life and non-reactive interaction with nitriding atmosphere
  • Uniform temperature distribution obtained through independently controlled heating zones
  • Intensive atmosphere circulation ensures full control of nitriding potential throughout all stages of the process
  • Light ceramic fiber insulation reduces heat loss and thus energy consumption
  • Kanthal long-lasting heating elements
  • Integrated cooling system
  • Possibility of outfitting larger size furnaces with ‘Turbo’ cooler to significantly reduce the load cooling time. This option is ideal when productivity is a major issue.
  • Minimal maintenance
  • Preconfigured and factory-tested
  • Pretested for metallurgical results
  • Fully automated operation guarantees repeatable and consistent results
  • True Nitriding/Nitrocarburizing Process Control – Compliant with AMS 2759/10 and AMS 2759/12 standards
  • Superior case properties per customer specifications
  • Various case configurations possible
  • Repetition of results
  • System for data archiving and reporting as well as remote diagnostics
  • SCADA connectivity
  • Clean, environmentally-friendly processes powered by Nitrex effluent neutralizers

PROCESS CAPABILITIES

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 automatic, self-adjusting and operator-independent.

 

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 cycle flow
  • 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 and 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, cool) are automatically sequenced in one uninterrupted cycle, without further operator intervention. This setup provides a high degree of accuracy in process execution, contributing to consistent nitriding/nitrocarburizing results.
