%0 Journal Article %T Influence of the steel scrap classes on the liquid steel output molten in electric steel processes %A K. Janiszewski %A J. Pieprzyca %A Z. Kudli¨½ski %J Journal of Achievements in Materials and Manufacturing Engineering %D 2012 %I World Academy of Materials and Manufacturing Engineering %X Purpose: This is why we have analysed in the paper, using statistical analysing methods, the influence of use in the electric arc furnace charges of steel scrap of different qualities on the index of liquid steel output from a melt.Design/methodology/approach: The used research methodology consists in analytical simulation of variations in mass of liquid steel obtained from melts differing in steel scrap content in the metallic charge and statistical analyses of industrial results acquired from the corresponding process documentation (so called melt cards).Findings: Basing on the analytical and statistical analyses carried out we have determine resulting variations in the liquid steel per melt ratios depending on the content of steel scrap in the metallic charge.Research limitations/implications: The research results obtained can be utilized in each steelmaking facility, which employs the Electric Steelmaking process, in order to ¡°design¡± the metallic charge compositions, having in view the quality and economic aspects.Practical implications: The research results presented in the paper can be used for steel production of high purity steels.Originality/value: The results presented in this paper are directed to the steelmakers employing the Electric Steelmaking process and constitute the authors¡¯ original study. %K Metallurgy %K Liquid steel %K Ferrous scrap %K Electric arc furnace %U http://journalamme.org/papers_vol55_2/58244.pdf
