Application note

Small spot mapping - XRF as a process control tool for chemical chracterization of macro-segregation occuring during continuous casting in steel

The continuous casting of slabs is aimed to produce a product with a certain chemical composition, geometry and surface quality, without any or a minimum acceptable level of external and internal defects. One of the most unpredictable defects of the slabs is centerline segregation, which has undesired effects on further processing of the slabs and hence on the possible uses of the final product.

This application note demonstrates the capability of practical, fast elemental distribution mapping of two steel samples showing chemical segregation, analyzed for quality control purposes.
