Sažetak
Three-dimensional mathematical model of the solidification of steel ingot in a chilled mould has been formulated and investigated in the paper. The model is based a priori on knowledge and it is supplemented with expirience data. In the mathematical model the thermophysical data are incorporated which are temperature dependent, what gives nonlinearity to the model. The model is solved by means of explicit finite difference method - the method of enthalpy. The solidification algorithm has been solved with computer SPERRY 1106 in program language ASCII FORTRAN. The time of solidification, the optimum stripping time, the thickness of the solid skin in any direction, and the potentional points of possible defects in ingot may be obtained on the basis of the model.
