Product Introduction
The oxygen probe is a cornerstone in the metallurgical industry, masterfully designed for delivering precise and instantaneous assessments of oxygen content and temperature within molten steel. It plays a pivotal role in upholding quality assurance in steel-making ventures by streamlining smelting processes, ensuring precise deoxidizer applications, and markedly shortening smelting durations. By offering instantaneous insight into oxygen activity, it elevates steel quality, amplifies product compliance, and curtails raw material usage. This versatile probe is extensively employed across diverse steel-making settings such as converters, electric furnaces, and sophisticated refining stations including LF and RH.
The oxygen probe is powered by cutting-edge solid-electrolyte concentration cell technology, integrating a half-cell with a thermocouple to create an oxygen concentration cell. By linking a reference electrode with a fixed oxygen partial pressure to molten steel containing oxygen through an oxygen-ion solid electrolyte, it precisely assesses the oxygen potential and temperature of molten steel. Using the Nernst law, it calculates oxygen activity with unparalleled precision, rapid response, and exceptional stability, ensuring consistent, reliable measurement outcomes. This probe is instrumental in optimizing and refining steel-making processes, delivering significant improvements and advancements.
