Abstract：To describe the solidification in caster mold, a twodimensional fully thermomechanical coupled finite element model was established. The model is solved with MSC Marc software. The solidification of slab in the molds with longitudinal parallel grooves separated by different intervals on the inner surface was simulated.The influence of grooves on the solidification of slab was studied. The results show that heat transfer between mold and initial solidified shell is improved by grooves. So grooving is beneficial to the uniform shell growth, and reduction of stress concentration and cracking.
