Analysis of Macroscopic Structure and Prediction of Convection in Sato Mold Using Water Model

To intuitively understand non-uniform solidification and macrosegregation during continuous or ingot casting, the solidification structure of a transparent ammonium chloride aqueous solution was observed using a bridging-inducing Sato mold. First, using a heat-resistant glass cell equipped with a chill plate, the crystal growth of ammonium chloride dendrites near the chill plate was In-situ observed, and also an appropriate cell design was considered. Furthermore, using a constant flow velocity manufacturing device equipped with an electromagnetic stirrer, the relationship between the dendrite growth behavior and the perpendicular liquid flow velocity was investigated, and finally the flow velocity near the dendrite was estimated inside the mold.
