Fast and Accurate Quantification of Elemental Macrosegregation in Continuously Cast Slabs using the Micro-XRF Technique
Abstract
Macro-segregation adversely affects the mechanical performance of continuously cast steel slabs. Micro X-ray fluorescence (micro-XRF) with a 20 µm spot size enables rapid elemental analysis. This study investigates the spatial distribution of manganese, silicon, and aluminum in thin slab caster samples using a Bruker M4 Tornado system. The combination of Fundamental Parameter (FP) calibration and Quantification of Pixels within the Map (QMAP) processing enabled accurate quantification of elemental variations. The results were further validated through multi-scale analyses using Confocal Laser Scanning Microscopy (CLSM) and Scanning Electron Microscopy (SEM-EDS). The optimized methodology provides an efficient and reliable approach for quantitative segregation assessment.
