Product Introduction
The oxygen and temperature measurement probe by Tangshan Jinyi Instrument Co., Ltd. is an indispensable tool in the metallurgical sector, designed to deliver precise and swift evaluations of oxygen content and temperature in molten steel. This innovative device is essential for maintaining high standards of quality control during the steel-making journey. It optimizes smelting efficiency, ensures the correct incorporation of deoxidizers, and significantly reduces the time required for smelting. By offering instantaneous data on oxygen activity, this probe is instrumental in elevating the quality of steel, boosting product approval rates, and minimizing the use of raw materials. Its versatility is evident as it is effectively utilized in a myriad of steel-making contexts, including converters, electric furnaces, and sophisticated refining stations like LF and RH.
The technologically advanced oxygen probe from Tangshan Jinyi relies on the cutting-edge solid-electrolyte concentration cell technique. It is constructed using a half-cell alongside a thermocouple to create an oxygen concentration cell. This is achieved by connecting a reference electrode, which has a pre-determined oxygen partial pressure, to molten steel containing oxygen via an oxygen-ion solid electrolyte. By gauging the oxygen potential and the temperature of the molten steel, the probe calculates the oxygen activity based on the Nernst law. It stands out for its exceptional precision, rapid response time, and remarkable stability, ensuring dependable measurement outcomes. These features make it a vital asset in the regulation and enhancement of steel-making processes.
