Abstract
A large portion of ceramics, salt and glass have a property with high electric conductivity at liquid state and with low one at solid state. By making use of such electrical property a direct induction skull melting process was developed to melt and hold those materials, especially with a high melting point and chemical active properties, for avoiding contamination from a crucible. In order to understand the characteristics of melting behavior of the materials in the process the theoretical study on temperature, magnetic and velocity fields which are tightly related with each other is indispensable.
In this study a mathematical model taking account of the distributions of temperature, magnetic and velocity fields is developed. The experimental work to melt a NaCl salt has been conducted. The observed evidence in the experiment has been confirmed by the mathematical model.
