Sažetak
In this paper we investigate the solidification simulation of a steel rail-wheel casting in a sand mould. The mathematical model is solved numerically using the finite difference implicit - alternating - direction method and the program is written in the FORTRAN 77 computer language for a DX-4S personal computer. On the basis of the simulation it is possible to study computer-aided design, which involved changing the width of the web that connects the flanged rim to the hub of the wheel. It is also possible to determine the optimum height of the classical riser attached to the top of the wheel hub to avoid casting defects and, with the high degree of confidance, produce a sound casting.
