Product Introduction
The oxygen probe stands as an essential tool in the metallurgical industry, renowned for its precision in swiftly determining both the oxygen content and temperature of molten steel. This pivotal instrument is integral to the quality assurance within steel-making, streamlining smelting processes to perfection, ensuring deoxidizers are added accurately, and significantly shortening smelting durations. By delivering real-time insights into oxygen activity, it not only elevates the quality of steel but also boosts the rates of product qualification and curtails the consumption of raw materials. This versatile probe finds extensive applications across diverse steel-making environments such as converters, electric furnaces, and refining stations including LF and RH.
The functioning of the oxygen probe is rooted in solid-electrolyte concentration cell technology. It ingeniously comprises a half-cell and a thermocouple, forming an oxygen concentration cell by linking a reference electrode, known for its oxygen partial pressure, with molten steel containing oxygen, through an oxygen-ion solid electrolyte. By accurately measuring both the oxygen potential and the temperature of molten steel, it calculates oxygen activity following the principles of Nernst's law. With its exceptional precision, rapid responsiveness, and remarkable stability, this probe guarantees reliable measurement outcomes, playing a vital role in enhancing control and efficiency in steel-making operations.
