Offline Digital Twin for ArcelorMittal Dofasco’s No. 2CC using 3D THERCAST® modelling to predict macrosegregation & cracking

During the metallurgical production process of steel, such as continuous casting, the defects forming during solidification process greatly impair the final properties of steel products which can only be modified to a limited extent in the subsequent processing. The common casting defects such as macrosegregation and cracking in continuously cast steel slabs have plagued the industry for decades as they are multi-physics and multi-scale problem and extremely hard to solve. In this project, a macroscale process modelling work combined with experimental investigation is proposed to study the solidification and deformation behavior of casting steel. This research will help metallurgists to have a better idea of the range of alloys compositions that can be industrially produced and alleviate the long-term severe problems during casting, which allows for the increase of productivity and optimization of casting procedures.
