Product Introduction
An oxygen probe is an indispensable tool in the metallurgical industry, meticulously designed to deliver exacting and swift measurements of oxygen content and temperature in molten steel. This device is integral to maintaining superior quality control throughout the steel-making process, facilitating the optimization of smelting operations, ensuring the precise addition of deoxidizers, and significantly reducing smelting durations. By providing real-time oxygen activity data, it plays a crucial role in elevating steel quality, boosting product qualification rates, and minimizing raw material usage. This probe finds extensive application in diverse steel-making environments, such as converters, electric furnaces, and refining stations like LF and RH.
The oxygen probe operates on the sophisticated principle of solid-electrolyte concentration cell technology. It comprises a half-cell and a thermocouple, forming an oxygen concentration cell by linking a reference electrode (with a known oxygen partial pressure) to molten steel (with oxygen content) via an oxygen-ion solid electrolyte. By measuring the oxygen potential and temperature of the molten steel, it computes the oxygen activity in accordance with the Nernst law. Boasting high precision, rapid response, and excellent stability, this probe provides trustworthy measurement results, contributing profoundly to the management and enhancement of steel-making processes.
