Product Introduction
The oxygen probe is an indispensable tool in the metallurgical industry, specifically engineered to deliver precise and swift measurements of oxygen content and temperature in molten steel. It holds a crucial position in quality control during steel-making processes. This enhances the efficiency of smelting operations by ensuring accurate deoxidizer addition and reducing smelting durations. By offering real-time insights into oxygen activity, the probe significantly elevates steel quality, boosts product qualification rates, and minimizes raw material usage. This versatile instrument is extensively utilized in various steel-making environments, including converters, electric furnaces, and refining stations such as LF and RH.
At the heart of the oxygen probe's functionality is the solid-electrolyte concentration cell technology. It comprises a half-cell and a thermocouple that form an oxygen concentration cell. This is achieved by linking a reference electrode (with a predetermined oxygen partial pressure) and molten steel (with its inherent oxygen content) through an oxygen-ion solid electrolyte. By gauging the oxygen potential and temperature of the molten steel, it proficiently computes the oxygen activity based on the Nernst law. Renowned for its high precision, rapid response, and robust stability, this probe guarantees dependable measurement results, substantially contributing to the evolution and refinement of steel-making procedures.
