Numerical simulation of electromagnetic levitation melting process considering temperature dependence H. Kawaguchi & T. Honma Department of Electrical Engineering, Faculty of Engineering, Hokkaido University, Kita 13, Nishi 8, Kita-ku, Sapporo 060, Japan ABSTRACT This paper discusses determination of a metal shape in electromagnetic levitation melting process considering temperature dependencies. In this process, the surface tension plays a important role for determination of the metal shape. From this point of view, an estimation method of the temperature and the temperature dependence of the surface tension are considered. INTRODUCTION The electromagnetic levitation melting process is a complex system including the electromagnetic force, gravitation, surface tension and fluid motion. The metal shape changes variously depending on these forces. To analyze this process theoretically, numerical calculation is necessary. There exist some numerical methods to analyze this s
