Product Introduction
Oxygen Lance, also known is a specialized tool used in steelmaking to measure dissolved oxygen content in molten steel while simultaneously monitoring temperature, enabling precise process control during refining. Equipped with advanced zirconia-based oxygen sensors and precision thermocouples, it directly immerses into the steel bath to deliver real-time data on oxygen activity (±2mV accuracy) and temperature (±2°C precision) within 2-5 seconds.
Primarily used in basic oxygen furnaces (BOFs), electric arc furnaces (EAFs), and ladle refining stations, the Oxygen Lance plays a critical role in optimizing decarburization, adjusting alloying additions, and achieving targeted endpoint compositions. By providing immediate feedback on oxygen levels, it allows operators to fine-tune blowing strategies, reduce reblows, and minimize energy consumption. For example, in BOFs, it helps maintain the carbon-oxygen equilibrium during the blow, ensuring efficient removal of impurities while controlling heat generation.
