Accelerating Slag Analysis in Ladle Furnace Operations: An OES Approach for Improved Process Control

This paper discusses the implementation of a laser optical emission spectroscopy (OES) analyzer for accelerated slag analysis in ladle furnace operations. Traditional slag analysis methods are slow, taking up to 15 minutes, which impacts process efficiency and precise deoxidation. The Laser OES analyzer provides rapid, direct analysis without requiring sample homogenization, which is essential for real-time adjustments. Challenges arise from using nonprepared samples and the lack of certified reference materials for calibration, necessitating secondary sample use. This approach enables precise, faster slag composition monitoring, optimizing operational control and reducing time delays.
