Principle

The oxygen probe operates based on the principle of electrochemical measurement. The key components and their functions are as follows:

• Electrolyte: The probe contains a solid electrolyte that conducts oxygen ions. When the probe is immersed in molten steel, oxygen ions migrate through the electrolyte, creating a potential difference.
• Reference Electrode: A reference electrode is used to provide a stable reference potential. This allows for the accurate measurement of the oxygen potential in the molten steel.
• Measurement Electrode: The measurement electrode detects the potential difference created by the migration of oxygen ions. This potential difference is directly related to the oxygen content in the molten steel.
• Temperature Measurement: The probe also includes a thermocouple or other temperature-sensing element to measure the temperature of the molten steel. This temperature data is crucial for interpreting the oxygen potential measurements.

By combining these elements, the oxygen probe can accurately measure both the temperature and the active oxygen content in molten steel. The electrochemical principle ensures that the measurements are both precise and reliable, providing essential data for process control and quality assurance.
