PREDICTION OF THE PROPERTIES OF ALLOYING ADDITIVES IS AN IMPORTANT COMPONENT OF RECEIVING QUALITY METAL

Abstract

The main goal of the work is to predict the complex of physicochemical and thermophysical properties of additives from the standpoint of their contribution to the directed formation of the quality of steels. As a scientific basis for the development of analytical dependencies, the work uses the original concept of directional chemical bonding, the core of which is the consideration of metal melts as chemically unified systems, and not a mechanical mixture of constituent elements, and taking into account the contribution of all components, even in small concentrations, as well as the accumulated experience of creating information and analytical systems for forecasting and management of iron and steel smelting processes at the Iron and Steel Institute of Z.I. Nekrasov National Academy of Sciences of Ukraine. The information component is a database on the properties of metallurgical melts, namely the "Ferroalloys" database chosen as the starting point for modeling, which is continuously updated with modern data. A successful combination of information and scientific resources ensured the development of stable models with high forecast accuracy (R2 ≥ 0.95) for domestic brands of ferroalloys (ferromanganese, ferrosilicomanganese, metallic manganese). The findings presented in this work are recommended for integration into the automated technological process management systems of steelmaking with the aim of further forming a competitive final product.
