Three-Dimensional Mathematical Model of the Solidification of Large Steel Ingots
V. Grozdanić
Abstract
Three-dimensional mathematical model of the solidification of low-carbon steel ingot in a chilled mould has been formulated and invest-igated in the paper. The model is based on theoretical knowledge and it is supplemented with experience data. In the mathematical model the thermo physical data are incorporated which are temperature dependent, what gives nonlinearity to the model. The model is solved by means of the 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 prints of possible defects in ingot may be obtained on the basis of the model.
