Sažetak
Two-dimensional mathematical model of fusion of cylindrical steel scrap in converter melt was developed. The model was solved using implicit aternating direction method. The obtained algoritham was programmed in ASCII FORTRAN for the computer SPERRY 1100/72. Temperature dependent thermophysical properties of material were incorporated in the model. That gives a nonlinearity to the model. On the basis of the model it was concluded that addition of 1% of low carbon steel scrap decreases the temperature of a middle carbon steel melt for cca 20C. This is in good agreement with experimental data from literature. The mathematical model was tested for one-dimensional solution using Bessel functions. A good agreement was found.
