Databases and Models to Support the Acceptance of Technological Decisions in the Proofing of Steel at the Ladle Furnace Installation

The need to develop the databases of the «Metallurgy» industry data bank in order to preserve unique industrial and laboratory experimental data, which can be the basis of licensed profile computer programs, is substantiated. Emphasis is placed on the importance of the development of calculation methods for determining the primary properties of ferroalloys, which will ensure that industrial metallurgists receive adequate data for further operational decision-making in the production of competitive and high-quality steel and their introduction into automated technological process control systems. Based on the concept of directional chemical bonding, models have been developed that allow predicting important physicochemical and thermophysical properties that are the limiting factors in the efficiency of interphase interaction processes, in particular, of manganese-containing ferroalloys with sufficient accuracy for industrial use.
