Baking of Thin Electrically Non-conductive Layers by Indirect Induction Heating

摘要

A model of baking electrically non-conductive thin layers (paints, lacquers and other covering material) is presented. The process of baking, whose purpose is to protect the metal substrate from unfavourable influences of environmental medium, is realized by indirect induction heating of the metal substrate that transfers heat to the thin layer by conduction. The electromagnetic and temperature fields in the system are described by two partial differential equations for the magnetic vector potential and temperature. Some important results of the process are verified experimentally with a very good accordance.
