Product Introduction
An oxygen probe is an indispensable instrument in the metallurgical industry, meticulously designed to precisely and swiftly measure both oxygen content and temperature in molten steel. This critical tool plays a vital role in quality control throughout steel-making processes, optimizing smelting operations, ensuring precise addition of deoxidizers, and significantly reducing smelting time. By offering real-time insights into oxygen activity, the probe enhances steel quality, boosts product qualification rates, and curtails raw material usage. Its applications are extensive, finding use in diverse steel-making settings including converters, electric furnaces, and refining stations such as LF and RH.
The oxygen probe is based on advanced solid-electrolyte concentration cell technology. It features a half-cell and a thermocouple, together creating an oxygen concentration cell by linking a reference electrode (with a predetermined oxygen partial pressure) to molten steel (carrying oxygen content) through an oxygen-ion solid electrolyte. By evaluating the oxygen potential and temperature of the molten steel, it computes oxygen activity in accordance with the Nernst law. Renowned for its high precision, rapid response, and exceptional stability, this probe guarantees reliable measurement outcomes, making a significant contribution to the management and enhancement of steel-making processes.
