The results of investigations of the mathematical model of the process of firing ceramic tiles in a slot furnace are given, taking into account the dynamics of the thermal process for determining the parameters of the equipment and the rational temperature control law. The implementation of the model in the MATLAB Simulink environment made it possible to optimize the system. Purpose. Develop and conduct a study of the mathematical model, taking into account the dynamics of the thermal process for determining the parameters of equipment and the rational law of temperature control, which will improve the quality of ceramic tiles and reduce energy intensity. Methodology. As an object for the study, a slot furnace for baking ceramic tiles was adopted. The influence of controlling and disturbing factors on the temperature in the furnace was investigated. On the basis of the obtained data, the equation of the object dynamics and the transfer function of the slit furnace with the control action are determined. To perform optimization of the firing process control system, a block diagram of the process model implemented in the Simulink environment of the MATLAB 6.5 software package was developed. Findings. As a result of the mathematical modeling of the ceramic tile firing process in the slot furnace, the equations of the object dynamics, the transfer function of the furnace with the control action are determined, the dynamic parameters of the system are calculated and then modeled using the Simulink simulation package of the MATLAB 6.5. Optimization of the system was carried out. Originality. An imitation model of a roasting kiln was created, taking into account external factors and rational rational parameters of the elements of the system, equipment and rational temperature control law were determined. Practical value. The block diagram of the mathematical model of the ceramic tile firing process and its simulation model developed and implemented with the help of MATLAB 6.5 software allows to determine the rational and desired time of the transient process at the design and debug stage, optimize the system, improve the quality of the firing process, and reduce the coolant flow.
