Sažetak
In the paper there is presented a statistical analysis of the influence of various quality classes and the amount of scrap in steel charges on the rate of liquid steel yield from the electric arc furnace (EAF). The research methodology involved the analytical simulation of changes in the liquid mass of steel acquired from melts with different scrap content and statistical analysis of data obtained from the correlating process documentation (so-called melting sheets) under industrial conditions. The attained results may be employed in any steel mill that uses electrical steelmaking processes, to design the composition of a metal charge while bearing in mind the qualitative and economic aspects.
