Atmosphere control is a critical part of bell annealing. Whether it is hydrogen, nitrogen with propylene, or another combustible atmosphere, the atmosphere control system must assure safety under all conditions. All RAD-CON systems exceed the requirements of USA’s National Fire Protection Association (NFPA) code 86C.

Consistent decarburization and soot prevention during heat treatment of ferrous wire is critical for most product applications. RAD-CON 100% Hydrogen Anneal is a viable solution for new installations but existing nitrogen-based equipment can also produce acceptable product utilizing one of the RAD-CON Atmosphere Control Systems.

RAD-CON has two available Atmosphere Control Systems: APEx (Atmosphere Process Equilibrium) and ACCS (Activity of Carbon Control System), both using proprietary algorithms to accurately control the atmosphere potential during the process. The application of one or both of the systems will depend on the annealing method (sub-critical or super-critical) and atmosphere gas. Contact RAD-CON for advice on the proper system for your shop.
