Study of cleanliness and castability in Ti-stabilized ultra low carbon steels using automated SEM inclusion analysis
S.-R. Story, G.-E. Goldsmith and G.-L. KlepzigPublished online: 5 June 2008
Abstract
Titanium-stabilized ultra-low carbon steels are often used in surfacequality
critical applications and also susceptible to clogging
problems in the casting process. The Automated Steel Cleanliness
Analysis Tool (ASCATTM), based on computer-controlled scanning
electron microscopy, was used to quantify the content and
compositions of inclusions present in the steel. The effects of alloy
addition timing at the RH degasser and of tundish slag composition
on cleanliness in these grades are discussed.
