Product Introduction
In the realm of metallurgy, the oxygen probe emerges as an indispensable tool, esteemed for its precision and speed in gauging both oxygen content and temperature within molten steel. This instrument is vital for quality assurance throughout the steel-making journey, meticulously enhancing the efficiency of smelting operations, guaranteeing the precise integration of deoxidizers, and efficiently reducing smelting time. By delivering real-time insights into oxygen activity, the probe is instrumental in elevating steel quality, bolstering product qualification rates, and curtailing the consumption of raw materials. Its versatility shines across various steel-making environments, including converters, electric furnaces, and refining stations such as LF and RH, making it an essential component in the steel production process.
Powered by cutting-edge solid-electrolyte concentration cell technology, the oxygen probe is a marvel of modern engineering. It elegantly combines a half-cell with a thermocouple to create an oxygen concentration cell, bridging a reference electrode with known oxygen partial pressure and molten steel, rich in oxygen content, through a robust oxygen-ion solid electrolyte. By adeptly measuring the oxygen potential and temperature of molten steel, it leverages the Nernst law to deliver accurate calculations of oxygen activity. Renowned for its remarkable precision, rapid response, and unwavering stability, this probe is a cornerstone of reliable measurements, playing a crucial role in refining and optimizing steel-making processes.
