Development of the structure of a cyberphysical control system for the process of tailored induction heating of a steel billet

The article is devoted to the development of the structure of a cyberphysical control system for the process of zone induction heating, widely used in modern industrial production during the heat treatment of metal products for various purposes. An analysis of the range of products manufactured using induction heat treatment and the advantages of using induction heating systems has shown a wide range of applications of this method of heat treatment in modern production and great opportunities for automation and optimization of processes associated with induction heating of products. This fact indicates the relevance of the development of various kinds of intelligent control systems in relation to the processes of industrial induction heating of metal blanks and semi-finished products. The article describes the induction method of zone heat treatment of metals, its advantages over flame heat treatment methods and the range of products manufactured using it. A description of the billet-inductor system is presented, for which the structure of a cyberphysical control system for the process of zone induction heating has been developed. The technological requirement for the final temperature distribution on the surface of the workpiece and the factors influencing the deviation of the temperature distribution from that required in the process of zone induction heating are considered. A list of possible disturbing influences is given, requirements for the technological process are formulated, control principles are described and, based on this, the structure of the zone induction heating process control system, which belongs to the class of cyberphysical process control systems, is developed.
