Abstract Scope |
Solidification shell deformations of hypo-peritectic steel within the mold during continuous casting have been calculated in order to clarify the influence of mold flux infiltration variability on the cooling rate, the width of the low heat flux region, the height of air gap, the unevenness of solidified shell, and the resulting strain in the solidified shell. A sequentially coupled thermal-mechanical finite element model has been developed and the simulation includes heat transfer and shell deformation of solidified shell during the delta-to-gamma transformation. Further, it takes into account the effects of variability in mold flux infiltration and air gap formation on heat transfer into the mold, as well as the effect of cooling rate on the thermal expansion. The results showed that mild cooling and low variability in mold flux infiltration strongly decrease the height of the air gap, the unevenness and the strain in the solidified shell. |
