Digital Twin of the Vulcanization Process Protective Coating Material Made of Rubber Concrete on the Surface of the Pipe Metal

Statement of the problem. To automate and optimize the technological processes of forming a protective coating of pipe metal, it is advisable to develop a digital twin of the heat treatment process of the protective coating material made of rubber mastic (caouton) on the surface of pipe metal using induction heating. Results. The developed mathematical model of the temperature field distribution in a vulcanized caouton-based coating made it possible to establish optimal modes of heat treatment of rubber mastic on the surface of pipe metal during the structuring of the protective coating material, taking into account the influence of existing external influences on the technological process. Conclusions. The use of a digital twin of the vulcanization process of the protective coating of pipe metal made it possible to retrofit the heat generating unit with a programmable thermostatic device that allows generating optimal temperature conditions for vulcanization of caouton, which made it possible to automate and regulate the technological process of introducing thermal energy into rubber mastic for structuring caouton on the surface of pipe metal. As a result, a protective coating with maximum strength and performance characteristics was obtained.
