AFinite Element Model for 2-Dimensional Slice of Cast Strand

A two-dimensional thermo-elasto-plastic finite element model for the analysis of thermo-mechanical behavior of strand in the continuous casting process has been developed. The model incorporates the effect of microsegregation of solute elements on hot tears using a thermo-mechanical model of mushy zone and solid phases. A finite element technique for the liquid region of the slice of strand, which can take into account the ferrostatic pressure due to gravity force, was proposed. The model successfully analyzed the thermo-mechanical behavior of the solidifying shell of slab in the mold during solidification. The calculated results, including deformed geometries, temperature history, stress distribution, and the formation of air gaps between the solidifying shell and the mold in the continuous casting process of slabs, were obtained and compared with reported observations.
