Simulation of shrinkage and stress in solidifying steel shells of different grades

Solidification Processes and Microstructures: A symposium in honor of Wilfried Kurz Edited by M. Rappaz IMS (The Minerals, Metals & Materials Society), Charlotte, NC, March 15-18, 2004, pp. 33-39This paper summarizes recent work with computational models to predict these phenomena for
steel, during the continuous casting process. The model is first validated by comparison with
measurements of a "Submerged Split Chill Tensile" (SSCT) test. This important measurement
tool was pioneered by Kurz [1] to study mechanical behavior and failure phenomena during solidification. The model is then applied to predict shrinkage during continuous casting of steel, investigating the effect of grade. Finally, simplified models to predict shrinkage are evaluated.
