Abstract
The build-up formation (clogging) is one of the processes which reduces the life- time of the inductors of the high-power induction channel furnaces (ICF). There is no generally accepted theory describing properly the mechanisms of the clogging. The theoretical basis for the build-up formation via the molecular crystallization is developed in the present paper showing the role of temperature and hydrodynamical fields in the build-up formation. The excellent qualitative agreement with this theory has been demonstrated by a comparison of the typical deposit formation rules in the industrial ICF and the theoretical predictions.
