Product Introduction
Our state-of-the-art oxygen probe plays a pivotal role in the metallurgical industry. Expertly crafted, it delivers precise, swift measurements of both oxygen content and temperature in molten steel—vital for safeguarding quality in steel-making. This indispensable tool enhances the efficiency of smelting processes, assures accurate deoxidizer dosing, and significantly reduces smelting durations. By offering real-time insights into oxygen activity, it not only elevates steel quality but also boosts product compliance rates and minimizes raw material usage. This versatile probe is extensively employed in various steel-making environments, including converters, electric furnaces, and sophisticated refining stations like LF and RH.
The oxygen probe harnesses cutting-edge solid-electrolyte concentration cell technology. It features a half-cell paired with a thermocouple, creating an oxygen concentration cell by linking a reference electrode (with a predetermined oxygen partial pressure) to the molten steel (containing oxygen content) through an oxygen-ion solid electrolyte. This setup precisely measures the oxygen potential and temperature of the molten steel, calculating the oxygen activity as per the Nernst equation. With exceptional precision, rapid response, and remarkable stability, this probe ensures consistent, dependable measurement results, significantly contributing to the enhancement and refinement of steel-making processes.
