The Effect of Slab Thickness on the Solidification of Low Carbon Steel in Continuous Casting Process: A Simulation Case Study

One of the most important and effective factors in the solidification of the steel continuous casting process is the geometry of the strand. to study the effect of this geometry, the influence of slab thickness will be investigated. to this end, a thermal model is first proposed, and its reliability is verified by simulating another paper in the literature and comparing the results with that research. in the model of the present work, thermophysical properties are calculated based on the computational thermodynamics model, calphad technique. then three different thicknesses are chosen subject to the same cooling conditions and technological parameters. afterward, the metallurgical length and shell thickness for these thicknesses are compared. as the shell thickness is approximated by a square root function of time, holding the coefficient k, finally, the k factor of the mentioned thicknesses is extracted and compared with one another such that the higher the thickness, the higher the k coefficient.
