NXH Horizontal Series

Furnaces & Technologies Nitriding / Nitrocarburizing Turnkey Installations

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.

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.
