Product Introduction
The oxygen probe is an indispensable tool in the metallurgical industry, engineered for the precise and swift measurement of oxygen content and temperature in molten steel. Serving as a cornerstone of quality control in steel-making processes, it is instrumental in optimizing smelting operations, ensuring the accurate application of deoxidizers, and reducing smelting duration. By delivering instantaneous data on oxygen activity, this probe significantly enhances steel quality, boosts product qualification rates, and lowers raw material usage. Its versatile application across diverse steel-making environments, including converters, electric furnaces, and refining stations such as LF and RH, makes it an essential component of modern steel production.
Harnessing the power of solid-electrolyte concentration cell technology, the oxygen probe is constructed with a half-cell and a thermocouple, forming 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, it calculates oxygen activity via Nernst's law. This probe stands out with its high precision, rapid response, and excellent stability, ensuring dependable measurements that are crucial to controlling and enhancing steel-making processes.
