MATHEMATICAL MODEL FOR HEAT TRANSFER IN SOLIDIFICATION OF CONTINUOUSLY CAST SLABS

A mathematical model for the heat transfer in the solidification of continuously cast slabs is proposed. A finite difference equation considering the viewpoint of the thermal equilibrium both within the unit and between the neighbour ones is derived and used in computer simulation of the solidification process of the continuously cast mould. The influence of operating parameter variations including casting speed and temperature, liquid convection in pool, mould length, etc. upon the solidification process of mould is discussed.
