This article explores the persistent challenge of centerline segregation in continuously cast high-strength low-alloy steels. This phenomenon, characterised by elemental segregation along the billet or slab centerline during casting and cooling, can lead to structural weaknesses such as cracking and breaking in rolled and formed products. Traditional monitoring methods, like etching and optical imaging, are time-consuming and lack quantitative compositional data, making them subjective and difficult to compare across different plants and manufacturers.
To address these limitations, we introduce the IXRF Atlas system, a non-destructive micro X-ray fluorescence (μXRF) technology. This system offers rapid, automated elemental mapping with high spatial resolution, enabling precise identification and quantification of impurities and inclusions within steel samples. The Atlas system’s capabilities allow for efficient monitoring of macrosegregation before rolling and forming processes, potentially reducing production costs and improving material quality.
