The function and working principle of hydrogen probe
Jan 31,2026
The fixed hydrogen probe is mainly used to measure the hydrogen content in molten steel to prevent hydrogen embrittlement and improve the quality and qualification rate of steel products.
Main functions：
1.Hydrogen content measurement: The fixed hydrogen probe can measure the hydrogen content in molten steel in real-time online, ensuring that the hydrogen content during the smelting process is within a controllable range and avoiding the occurrence of hydrogen embrittlement, which is crucial for the production of high-quality steel.
2.Improving product quality: By accurately measuring hydrogen content, the hydrogen probe provides effective data support for smelting control, helping steel mills improve product qualification and quality.
3.Quick response: The fixed hydrogen probe has the characteristic of quick response, which can complete the measurement of hydrogen content in a short time, meeting the demand for rapid detection in steel production.
4.Easy to operate: The operating interface of this probe is usually designed to be simple and easy to operate, reducing the workload and difficulty of operators.
Application scenarios：
· Metallurgical industry: Hydrogen probes are widely used for hydrogen content detection in the steel smelting process, especially in the production of high-quality steel and special steel grades, becoming an essential detection tool.
· Liquid Steel Hydrogen Determination System: The hydrogen determination probe is usually used in conjunction with the liquid steel hydrogen determination system to automatically detect the hydrogen content by measuring the hydrogen partial pressure, ensuring the accuracy and reliability of the measurement results。
