Product Introduction
In the heart of the metallurgical industry, the oxygen probe stands as an indispensable tool. Masterfully crafted, it offers precise and speedy measurements of both oxygen content and temperature within molten steel. This device plays a pivotal role in ensuring quality assurance across steel-making operations, soaring the efficiency of smelting processes, streamlining deoxidizer additions, and dramatically shortening smelting durations. By delivering real-time insights on oxygen activity, it not only elevates steel quality but also boosts product compliance rates and optimizes raw material consumption. With its adaptability, this probe is extensively utilized in diverse steel-making environments, including converters, electric furnaces, and cutting-edge refining stations such as LF and RH.
The oxygen probe is powered by cutting-edge solid-electrolyte concentration cell technology. It ingeniously integrates a half-cell with a thermocouple, forming an oxygen concentration cell by linking a reference electrode (with a standard oxygen partial pressure) to molten steel (with inherent oxygen content) through an oxygen-ion solid electrolyte. This allows for precise measurement of the oxygen potential and temperature of the molten steel, determining the oxygen activity according to Nernst law. With unparalleled precision, immediate responsiveness, and exceptional stability, this probe assures consistent and dependable measurement results, critically aiding in the enhancement and refinement of steel-making processes.
