Abstract
A two-dimensional mathematical model has been undertaken to describe coupled liquid steel’s turbulent flow and heat transfer with solidification in the crystallizer of inverse casting. The solid-liquid phase change phenomena have been modeled by using the continuum formulations and considering the mush zone as porous media. The turbulence flow has been accounted for, using a modified version of the low-Reynolds-number k - ɛ turbulence model. A well-known numerical procedure, SIMPLE, has been used to solve the control equations. The effects of some main parameters on the solidification behavior have been studied, such as the casting speed, the thickness and the initial temperature of mother sheet, the superheat degree of liquid steel.
