Product Introduction
Within the dynamic realm of metallurgy, our oxygen probe emerges as an essential instrument, distinguished by its meticulous design and unparalleled precision. This remarkable tool offers swift and precise evaluations of oxygen content and temperature within molten steel, serving as a cornerstone in quality control. Its sophisticated capabilities enhance smelting efficiency, optimize the use of deoxidizers, and notably compress smelting durations. By delivering real-time intelligence on oxygen activity, it not only raises the caliber of steel but also ensures superior compliance rates while reducing raw material usage. This adaptable probe finds widespread application across diverse steel-making environments, including converters, electric furnaces, and cutting-edge refining stations such as LF and RH.
Our oxygen probe leverages state-of-the-art solid-electrolyte concentration cell technology. This intricate system integrates a half-cell with a thermocouple to form an oxygen concentration cell by linking a reference electrode (possessing a defined oxygen partial pressure) with molten steel (containing oxygen) through an oxygen-ion solid electrolyte. This assembly accurately determines the oxygen potential and temperature of the molten steel, employing Nernst's equation to calculate oxygen activity. With unmatched precision, rapid response, and exceptional stability, this probe ensures consistent and reliable measurements, profoundly assisting in the fine-tuning and advancement of steel-making methodologies.
