The controlled atmosphere carburizing furnace is an advanced heat treatment equipment that can perform carburizing or carbonitriding treatment on metal workpieces under specific atmosphere conditions, thereby improving the surface properties and overall properties of the workpieces. The reason why this furnace can achieve precise control of the carbon and nitrogen content in the atmosphere mainly depends on its unique atmosphere control system and process parameter adjustment.In a controlled atmosphere carburizing (carbonitriding) furnace, precise control of the atmosphere is achieved through a variety of means. First, the preparation of the atmosphere in the furnace is the key. Usually, specific raw gas and air are used to generate the required carburizing atmosphere or carbonitriding atmosphere in the furnace through a certain proportion and reaction conditions. These raw gases can include methanol, natural gas, propane, etc., which can be cracked to generate active gas components such as CO, H2, N2, etc. under different reaction conditions.Secondly, precise control of the atmosphere also depends on real-time monitoring and adjustment of the atmosphere in the furnace. In a controlled atmosphere carburizing (carbonitriding) furnace, advanced sensors and control systems are usually equipped to monitor the composition and concentration of the atmosphere in the furnace in real time. When it is detected that the carbon content or nitrogen content in the atmosphere deviates from the set value, the control system will automatically adjust the feed gas flow rate and reaction conditions to ensure the stability and precise control of the atmosphere.In addition, the controlled atmosphere carburizing furnace also adopts advanced process parameter adjustment technology. By adjusting parameters such as furnace temperature, reaction time, and atmosphere flow rate, the precise control of the carbon content and nitrogen content in the atmosphere can be further achieved. The adjustment of these parameters needs to be carried out according to the specific workpiece material and carburizing (carbonitriding) requirements to ensure the stability of the treatment effect and workpiece quality.It is worth mentioning that the controlled atmosphere carburizing furnace also has high flexibility and adaptability in atmosphere control. It can flexibly adjust the composition and concentration of the atmosphere according to different workpiece materials and carburizing (carbonitriding) requirements to meet various complex heat treatment requirements.In summary, the controlled atmosphere carburizing furnace achieves precise control of the carbon content and nitrogen content in the atmosphere through its unique atmosphere control system and process parameter adjustment technology. This precise control not only improves the effect of heat treatment and the stability of workpiece quality, but also provides strong support for the performance improvement and application expansion of metal materials.
