Selection of furnace for NH₃・nitriding atmosphere sintering | Corresponding to nitriding treatment and generated gas evaluation
Organize the furnace configuration suitable for NH₃ supply, gas generation, and nitriding treatment.
Are you considering firing in an NH₃ and nitriding atmosphere, nitriding treatment, and evaluation of generated gases? In treatments in an NH₃ atmosphere, the appropriate furnace configuration and safety measures vary depending on whether NH₃ is supplied externally, whether gases such as NH₃ are generated during treatment, or whether you want to nitrify the material. In evaluating NH₃ supply and generated gases, it is important to consider specifications that include gas flow control, exhaust dilution, decontamination, leak management, purging, and backflow prevention. On the other hand, for nitriding treatment, multi-atmosphere furnaces or carbon furnaces are selected based on temperature range, atmosphere, sample quantity, and reactivity. This document organizes the objectives of NH₃ and nitriding atmosphere firing, furnace type selection, gas conditions, safety measures, and points for reflecting in equipment specifications. ■ For firing and reaction evaluation in an NH₃ atmosphere ■ For confirming nitriding treatment and compositional changes ■ For evaluating NH₃ generated gases and considering exhaust safety measures ■ For confirming the differentiation between multi-atmosphere furnaces and carbon furnaces ■ For firing tests and condition exploration before equipment installation
