Influence of the Steel Scrap Classes on the Liquid Steel Output Melt in Electric Arc Furnace

Abstract:

The paper analyses methods, the influence of use of charges of steel scrap of different qualities in the EAF on the index of liquid steel output from a melt using statistical analysing methods. The used research methodology consists of analytical simulation of variations in mass of liquid steel obtained from melts differing in steel scrap content in the metallic charge and of statistical analyses of industrial results acquired from the corresponding process documentation (so called melt cards). The obtained research results 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. The results presented in this paper are directed to the steelmakers employing the Electric Steelmaking process and constitute the authors original study.
