Sensivity enhanced laser analysis (SELA) of steel melts for fast multi-element on-line analysis during ladle processing in secondary metallurgy

Objective

The goal of this research project is the performance evaluation of fast multi- element, on-line laser analysis during ladle processing in steel metallurgy with determination limits of less than 10 ppm, especially for carbon, phosphorus, sulphur and nitrogen, and also for other elements such as titanium, vanadium, niobium, and molybdenum. The novel research approach is sensitivity-enhanced laser analysis (SELA) by combination of increased steel ablation and optimised plasma excitation for higher spectrometric signals.
