The paper reveals the ultrahigh-frequency (UHF) method of measuring the moisture content of bulk materials in the form of charge in complex metallurgical processes, which is part of the non-destructive method of control. Theoretical and experimental studies of physical properties of materials in the form of blend containing enriched ore raw materials in metallurgical processes are presented. The mechanism of microwave electromagnetic wave action to study the optimum moisture content in the charge, in which the electromagnetic wave emitted by the directional transmitting antenna falls on the controlled non-conducting material with a thickness of d, is considered. It is substantiated that as the mass ratio of moisture increases, the active component σ and grows, increasing microwave energy losses. An analytical expression to estimate this perturbing factor of the dielectric properties of the dispersed medium is given. The implementation of simulation modeling of information-measuring signals (IMS), allowing to build models in complex metallurgical processes, is presented.
