Abstract
Transfer of chemicals between phases is an extremely important indicator for metallurgical systems. At the same time, for high-quality modeling, it is necessary to ensure the similarity of the models, that is, a certain criterion of chemical similarity, which will ensure the adequacy of the modeling, becomes relevant. Different criteria can be used to achieve chemical similarity, the choice of which depends on the importance of one or another aspect that affects the actual chemical reaction. The possibility of using the similarity of Gibbs energies as an indicator of the possibility of the reaction at the temperatures of metallurgical processes and the similarity of the initial concentrations was proposed and studied in the work during high-temperature modeling of the oxidation of silicon from hot metal. It was also mandatory to use the modified Froude criterion. Due to the proposed method of similitude modeling, brass with a mass fraction of zinc of 1%, which has a lower melting point than cast iron, was chosen as a model environment, that is, it requires less modeling costs. Comparison of the obtained results with the results of purging in similar conditions of hot metal showed the closeness of the data, which indicates the feasibility of the proposed method.
