Product Introduction
An oxygen probe is an indispensable tool in the metallurgical industry, designed to precisely and swiftly measure the oxygen content and temperature within molten steel. This device is essential for quality control in steel-making processes, optimizing smelting operations, ensuring the accurate addition of deoxidizers, and reducing smelting time. By delivering real-time insights into oxygen activity, the probe significantly aids in enhancing steel quality, boosting product qualification rates, and minimizing raw material usage. It finds extensive application across various steel-making operations, including converters, electric furnaces, and refining stations like LF and RH, making it a versatile choice for industry professionals.
The oxygen probe functions on the principle of solid-electrolyte concentration cell technology. It consists of a half-cell and a thermocouple, creating an oxygen concentration cell by connecting a reference electrode, which has a known oxygen partial pressure, to molten steel with its oxygen content through an oxygen-ion solid electrolyte. By measuring the oxygen potential and temperature of the molten steel, the probe calculates oxygen activity in accordance with Nernst's law. With attributes of high precision, rapid response, and excellent stability, this probe ensures dependable measurement outcomes, playing a crucial role in the control and enhancement of steel-making procedures.
