Physical and technical basics of induction melting processes

Teacher Egbert Baake, Hans De Keulenaer

Description

In this course the physical and technical basics of induction melting processes and technologies will be explained. During the introduction the author will demonstrate along typical features of induction melting, why today induction melting is used in many industrial processes.

In the first part of this course the physical basics will be discussed by explaining the fundamental equations. The most important features of induction melting like, Joule heat effect, induced current and power density distribution in the melt, electromagnet forces, free melt surface deformation, turbulent melt flow and stirring will be explained.In the following the physical principle of the industrial most important induction melting furnaces, the induction crucible furnace and the induction channel furnace, will be shown.

In the second part of this course the author will explain, how the heat and mass transfer processes in the melt of induction furnaces are caused and influenced by the turbulent melt flow. Along industrial oriented examples it will be shown how numerical simulation based on sophisticated turbulent models can be used today for improved process understanding and design of the melting processes and devices.

The recapitulation of the most important features of induction melting processes and technologies will conclude this course.
