Product Introduction
Imagine a groundbreaking instrument that is the heartbeat of the metallurgical industry! Our oxygen probe, a marvel of engineering, is crafted to deliver extraordinary precision and speed in measuring both the oxygen content and temperature of molten steel. This indispensable tool is at the core of quality assurance in steel-making, driving efficiency in smelting processes, ensuring precise deoxidizer additions, and dramatically shortening smelting times. By offering real-time insights into oxygen activity, it elevates steel quality, boosts product compliance rates, and slashes raw material consumption. This versatile probe is indispensable across a multitude of steel-making environments, including converters, electric furnaces, and cutting-edge refining stations like LF and RH.
Powered by the cutting-edge technology of solid-electrolyte concentration cells, our oxygen probe revolutionizes measurement accuracy. It integrates a half-cell with a thermocouple, constructing an oxygen concentration cell that links a reference electrode, with its defined oxygen partial pressure, to molten steel via an oxygen-ion solid electrolyte. This sophisticated setup ensures precision in measuring the oxygen potential and temperature of molten steel, meticulously calculating oxygen activity using Nernst's law. With unparalleled precision, rapid responsiveness, and exceptional stability, this probe delivers consistently reliable results, playing a pivotal role in the optimization and refinement of steel-making processes.
