Product Introduction
The oxygen probe is an essential asset in the metallurgical industry, expertly crafted to deliver precise and rapid measurements of both the oxygen content and temperature in molten steel. This indispensable instrument plays a crucial role in quality assurance for steel-making operations. It enhances smelting processes, ensures the accurate addition of deoxidizers, and significantly shortens smelting times. By providing real-time insights into oxygen activity, it elevates the quality of steel, boosts compliance rates, and reduces raw material consumption. The versatility of this probe makes it a valuable tool across a wide range of steel-making environments, including converters, electric furnaces, and advanced refining stations such as LF and RH.
The oxygen probe operates on advanced solid-electrolyte concentration cell technology. It comprises a half-cell and a thermocouple, creating an oxygen concentration cell by linking a reference electrode, with a defined oxygen partial pressure, to molten steel containing oxygen content through an oxygen-ion solid electrolyte. It precisely measures the oxygen potential and temperature of molten steel to calculate oxygen activity according to the Nernst law. With unmatched precision, rapid responsiveness, and remarkable stability, this probe delivers consistent and reliable measurement results, significantly contributing to the optimization and enhancement of steel-making processes.
