A numerical algorithm for the two-dimensional solidification problem in the twin-roll-type continuous casting system was presented in this paper. Attention was focused on the elucidation of heat transfer and flow characteristics in both the liquid and solid phases. The bounday fixing method (BFM) was adopted to handle the moving boundary and the resultant transformed governing equations for the solid and liquid regions were solved separately by using the usual explicit-type finite difference scheme. The mathematical model presented covers a wide range of casting parameters since the two-dimensional transport in both phases was taken into account. Another objective was to provide design parameters for maintaining a continuous casting process, such as the roll speed, the roll spacing, the initial temperature of molten material, and the solidification profile with special attention given to the end point of solidification.
