Abstract
Laboratory studies were carried out at an experimental facility in order to study the behavior of cast iron impurities in ferrocarbon melt during complex processing. 10 treatments were carried out, during which sampling and introduction of the reagent was performed. According to the research results, for the CaO-FeO-Na2CO3 system, maps of the pairwise influence of the components of the mixture on the degree of removal of impurities were constructed, as well as triple diagrams of the state of the influence of the components on the degree of removal of impurities during complex processing, which made it possible to determine the rational composition of the refining mixture for the conditions of laboratory research, namely – FeO – 30%, CaO – 60%, Na2CO3 – 10%. The technical and economic assessment made it possible to draw a conclusion about the expediency and perspective of the development of the option of complex processing of cast iron with a mixture of oxide components and the feasibility of further research.
