The role of mathematical models in improving the technology of blast furnace smelting is shown [1]. Examples of new developments of the Institute of Metallurgy of the Ural Branch of the Russian Academy of Sciences in the field of digital models of blast furnace production are given, in particular, two-dimensional and three-dimensional mathematical models of the thermal state of various zones of the blast furnace, the condition of the refractory lining and filling of the furnace, the forecast of the silicon content in cast iron [2, 3].

New developments in the field of analysis and control of various thermophysical and physico-chemical phenomena occurring in various zones of the blast furnace allow us to raise the technology and methods of conducting blast furnace melting to a fundamentally new level, allowing us to save fuel and energy resources.

The possibility of using a digital model at a keeping up with the process when using sensor readings through the database management system of the blast furnace shop of the metallurgical enterprise is shown.

The work was performed within the framework of the State Assignment of Institute of Metallurgy UB RAS.
