Modelling and measuring of temperature distribution in explosive cladded materials under induction heating

Abstract

The work focuses on the modelling and experimental verification of induction heating systems with multilayered loads made of paramagnetic materials obtained through explosive cladding. The research is driven by the industry’s increasing interest in multilayered materials in electrical engineering and electronics. In this case, two- and three-layered configurations, as well as a cylindrical-shaped work coil, were considered. The main parameter subjected to verification was the surface temperature of the batch and its distribution. Due to relatively high temperatures, three measurement methods were used for temperature verification and effectiveness comparison: thermal imaging camera, pyrometer, and thermocouple. Additionally, the developed numerical models will provide a better understanding of the phenomena occurring in multilayered materials under the influence of rapidly changing electromagnetic fields and their impact on the heating process of the entire load. The article also addresses the issue of constructing models with a high discretisation level.
