In this paper, our findings regarding the heat properties of exothermal isolation materials are presented. These materials are used as accessory materials in the process of casting steel and other metals. To properly gauge the right amount of exothermal or isolation coatings, which allow a controlled solidification process, the amount of heat released during the exothermal reaction as well as the isolating effect of the material need to be specified. To achieve certain heat properties during the process, introducing procedural control is necessary. The industrial process control method Exoprobe, used for measuring the heat properties in the company EXOTERM-IT LLC, an example of such a machine, was optimised and calibrated for the duration of our project. For the purposes of finding the heat properties of the material, a DTA apparatus was made and calibrated. The results of the analyses of the exothermal isolating material were compared with the results of the DTA measurements, performed on the STA 449 Jupiter apparatus. Based on our findings, the new apparatus accurately shows the temperature areas of the reactions, but not the surface of the peaks, through which the energy value of a single reaction could be measured. Exothermal isolation materials were also analysed by an industrial process control method Exoprobe, which is an efficient method for measuring the heat properties and the behaviour of the material in practice. Its advantage is a large sample size, providing more representative results compared to most other methods, as well as enabling the visual analysis of a sample during the activity. The Exoprobe method is therefore suitable for use as an industrial control method with the final testing of materials and can also be used when developing exothermal isolation materials.
