Product Introduction
Introducing our state-of-the-art oxygen probe – an essential instrument in the metallurgical industry designed for the precise and swift measurement of oxygen levels and temperature within molten steel. This indispensable tool plays a crucial role in maintaining quality control during steel-making processes. It optimizes smelting operations, assures the appropriate addition of deoxidizers, and significantly reduces smelting time. By delivering instantaneous data on oxygen activity, the probe enhances steel quality, boosts product qualification rates, and curtails raw material usage. Its versatility allows it to be employed across various steel-making environments, including converters, electric furnaces, and refining stations like LF and RH.
The oxygen probe employs advanced solid-electrolyte concentration cell technology. Constructed with a half-cell and thermocouple, it establishes an oxygen concentration cell by linking a reference electrode (with a predetermined oxygen partial pressure) and molten steel (containing oxygen) through an oxygen-ion solid electrolyte. By gauging the oxygen potential and temperature of molten steel, the probe calculates oxygen activity as per the Nernst law. Offering unmatched precision, swift responsiveness, and exceptional stability, this probe guarantees dependable measurement results, playing a vital role in the seamless control and enhancement of steel-making processes.
