真空渗碳的渗碳气体控制方法和系统
By detecting the concentration of carburizing gas outside the carburizing chamber and setting an initial concentration, and using the concentration difference to control the flow rate of carburizing gas, the problem of inaccurate control of acetylene gas usage during vacuum carburizing was solved, achieving both precise carburizing effect and reduced gas usage.

AI Technical Summary
In existing technologies, it is difficult to accurately control the amount of acetylene gas introduced during vacuum carburizing, resulting in poor carburizing effect. This is mainly because the measurement of hydrogen concentration is affected by the shape of the processed product and the furnace structure, leading to inaccurate measurements.
By detecting the concentration of carburizing gas outside the carburizing chamber and setting an initial concentration, the flow rate of carburizing gas, especially the flow rate of acetylene gas, is controlled using the concentration difference, thereby reducing the amount of carburizing gas introduced before and after reaching the carbon solid solution limit point.
This achieves a reliable and safe reduction in the amount of carburizing gas used, improves the accuracy and efficiency of the carburizing effect, and avoids gas waste.
