Purpose: The basic purpose of this publication is to demonstrate the influence of variations in composition of the metallic charge in the Basic Oxygen Steelmaking process on the converter performance. One of the methods considered is in increase of the content of steel scrap. The preliminary results of the researches carried out demonstrate such a possibility and improvement of the liquid steel per melt ratio. 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 Basic Oxygen 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 Basic Oxygen Steelmaking process and constitute the authors’ original study
