Product Introduction
An oxygen probe serves as an essential component within the metallurgical industry. It is meticulously engineered to deliver precise and rapid measurements of both oxygen content and temperature in molten steel. This instrument is crucial for maintaining quality assurance in steel-making operations, enhancing the efficiency of smelting processes, ensuring accurate deoxidizer additions, and dramatically reducing smelting times. By providing real-time data on oxygen activity, it not only boosts the quality of the steel but also increases product compliance rates and reduces the consumption of raw materials. This adaptable probe finds extensive application across various steel-making scenarios, 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 includes a half-cell combined with a thermocouple, forming an oxygen concentration cell by connecting a reference electrode (with a set oxygen partial pressure) and molten steel (containing oxygen content) through an oxygen-ion solid electrolyte. It precisely measures the oxygen potential and temperature of the molten steel, calculating the oxygen activity according to the Nernst law. With unmatched precision, swift responsiveness, and outstanding stability, this probe guarantees consistent and reliable measurement results, significantly aiding in the optimization and refinement of steel-making procedures.
