Product Introduction
An oxygen probe is an indispensable tool in the metallurgical industry, expertly designed to precisely and swiftly measure both oxygen content and temperature in molten steel. This essential device serves as a cornerstone in quality control during steel-making processes. It optimizes smelting operations, ensures the precise addition of deoxidizers, and significantly reduces the smelting duration. By delivering real-time data on oxygen activity, it elevates steel quality, boosts product qualification rates, and minimizes raw material use. This probe is extensively utilized across diverse steel-making environments, including converters, electric furnaces, and refining stations like LF and RH.
The oxygen probe functions based on advanced solid-electrolyte concentration cell technology. It consists of a half-cell and a thermocouple, forming an oxygen concentration cell by linking a reference electrode with known oxygen partial pressure to the molten steel's oxygen content through an oxygen-ion solid electrolyte. By assessing the oxygen potential and temperature of the molten steel, it accurately calculates oxygen activity using the Nernst law. With its high precision, rapid responsiveness, and exceptional stability, this probe guarantees reliable measurement outcomes, playing a crucial role in the enhancement and control of steel-making processes.
