Product Introduction
In the realm of metallurgical excellence, the oxygen probe emerges as a pivotal instrument, meticulously designed for the precise and swift measurement of oxygen content and temperature in molten steel. This indispensable device is a cornerstone of quality control within steel-making processes, playing a central role in optimizing smelting operations. It ensures the judicious addition of deoxidizers, thereby significantly reducing smelting time. By delivering real-time data on oxygen activity, it not only elevates the quality of the steel but also enhances product qualification rates and minimizes raw material consumption. Its versatility spans various steel-making environments, including converters, electric furnaces, and refining stations such as LF and RH, making it an essential tool in the industry.
Harnessing the power of solid-electrolyte concentration cell technology, the oxygen probe stands as a beacon of innovation. It constitutes a half-cell and a thermocouple, ingeniously creating an oxygen concentration cell by linking a reference electrode, with a known oxygen partial pressure, to molten steel, containing oxygen, through an oxygen-ion solid electrolyte. This sophisticated mechanism measures the oxygen potential and temperature of the molten steel, calculating the oxygen activity with precision, using the Nernst law. With attributes of high accuracy, rapid response, and remarkable stability, this probe delivers dependable measurement results, making a profound impact on the control and enhancement of steel-making processes.
