3-D numerical simulation and analysis of heat transfer, fluid flow and solidification inside the mould during continuous casting of steel

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.

A Three Dimensional simulation of mould in continuous casting process with consideration of standard k-& model has been presented and corroborated. The main difference between this work and previous ones is that the phase change process (solidification) and turbulent flow distribution have been coupled and solved jointly instead of dividing it into ''transient heat conduction process" and "steady fluid flow" that can lead to more realistic simulation. The main objective in this work is to have better understanding of the fluid flow pattern, heat transfer and solidification in the continuous casting mould Investigating the influence of superheating degree, nozzle port angle, casting speed, comparing the temperature distribution and analyzing other parameters, can lead us to a better design in the way of optimistic working condition.
