Abstract: To meet the increasingly stringent demand for structural integrity of steel for a variety of applications, achieving sound centerline quality in continuously cast slabs plays a significant role. Besides employing good steelmaking practices to achieve good cleanliness, it is widely recognized that certain casting conditions, particularly, the nature of soft reduction, play a significant role with respect to segregation of solute elements during continuous casting. Centerline segregation during continuous casting is caused by the rejection of solute elements from the solidifying shell into the liquid pool due to reduced solubility in the steel. Under this condition, the last liquid that solidifies can be highly enriched with solute elements causing severe microstructural inhomogeneity and throughthickness variation in mechanical properties of the steel. It has been documented that steel with severe segregation under performs with respect to toughness, through-thickness ductility, weldabilty and HIC resistance. SSAB is taking initiatives at its facilities to improve centerline integrity of its slabs through a combination of optimal soft reduction and casting conditions.

 

Speaker: Sunday Abraham earned his M.Sc. and Ph.D. degrees in Metallurgy and Steelmaking from Moscow Institute of Steel and Alloys (1986). In 1999 he moved to Canada and began working as a Research Engineer at the IPSCO R&D center in Regina, Saskatchewan. Sunday advanced to the Manager of the R&D department in 2004 and upheld that position for 4 years before moving to the Director of Technical Services. In August, 2010, Sunday moved to Monpelier, Iowa to work for SSAB as a Principal Research Engineer in the new R&D facility.
