Annotation. Mathematical models of the firing process presented in the literature are mainly divided into two directions: the study of physico-chemical processes of clinker formation with a significant chemical bias, and the study of thermal processes occurring in firing furnaces. To build a process control system, a mathematical model is required that contains measured values and control actions in the form of model variables, and reflects the relationship between these variables in dynamics. The available mathematical models of the firing process reflect a large number of physical parameters that are difficult to measure or calculate based on the measured data. In the proposed article, as models of the dynamics of the clinker calcination process during the preparation of cement in a rotary kiln, the heat balance equation describing the change in the physicochemical properties of the mixture of starting materials during calcination is used. A study of a mathematical model of the clinker firing process using modern information technologies, namely the MATLAB 9 program and the Simulink dynamic systems modeling package, has been carried out.
