The functional capabilities, methodological foundations and information software of a modernized computer system for controlling the slag regime of blast furnace smelting, developed at the Institute of Ferrous Metallurgy on the basis of fundamental principles in the physicochemical and mathematical modeling of metallurgical melts and systems based on the concept of directional chemical bonding, are considered. The system provides a predictive calculation of the complex of technological properties of the final blast furnace slag: viscosity, melting points, enthalpy, and desorption capacity. Operational assessment of the slag regime using the Slag system as part of the process control system allows efficiently and up-to-date solving the problems of optimizing the slag regime and pig iron quality under unstable blast furnace conditions
