Analysis of the methods of management of the domain melt on the <\/strong>basis of information about the form and position of the cohesive zone<\/strong><\/h3>\n

Abstract.<\/strong> The aim of the work is to formulate recommendations on the adoption of control actions on the course of smelting in modern conditions. The ideology of the modern intellectual decision support system for blast smelting management is based on providing the optimal plastic zone in the blast furnace
\n(DP). Blast furnace melting control methods are based on information on the shape and position of the plastic zone in the blast furnace. According to the results of research carried out by various scientists, it was shown that the plastic zone is a hollow cone, the walls of which consist of alternating horizontal coke
\nlayers with high gas permeability and low-permeable for gas layers of iron ore materials that are in a softened, semi-molten state. The work describes the factors that determine the shape and position of the plastic zone in the DP. The analysis carried out showed that the mode of loading of charge materials has
\nthe main influence on the formation of the plastic zone. It was noted that, in addition to various modeling methods, it is advisable to create a criterion for assessing the shape and position of the plastic zone, which would take into account its thickness, profile and position in the DP, to control and control the
\nblast smelting process. Developed recommendations for making management decisions during smelting.
