Product Introduction
An oxygen probe is an indispensable tool in the metallurgical industry, designed for highly accurate and swift measurement of oxygen content and temperature in molten steel. This device is crucial for quality control throughout steel-making processes, streamlining smelting operations by ensuring the precise addition of deoxidizers and reducing smelting duration. By delivering real-time insights into oxygen activity, the probe significantly enhances steel quality, elevates product qualification rates, and curtails raw material usage. This versatile probe finds extensive application across various steel-making environments, including converters, electric furnaces, and refining stations like LF and RH.
The oxygen probe leverages solid-electrolyte concentration cell technology for its operation. It consists of a half-cell and a thermocouple, creating an oxygen concentration cell through the connection of a reference electrode (featuring known oxygen partial pressure) and molten steel (containing oxygen content) via an oxygen-ion solid electrolyte. By assessing the molten steel's oxygen potential and temperature, it calculates oxygen activity in accordance with the Nernst law. This probe is distinguished by its high precision, rapid response, and exceptional stability, delivering dependable measurement results and playing a vital role in the enhancement and control of steel-making processes.
Brief |
Oxygen probe is an essential means for the control of carbon potential of the controlled atmosphere heat treatment. It is suitable for the heat treatment processes of carburizing, carbonitriding, annealing, protection atmosphere heating and bright quenching. Can be used in all kinds of industrial furnace, such as pit type furnace, mesh belt furnace, rotary hearth furnace and heat-absorbing gas generator. |
