Shape Modelling of Levitated Molten Metal in Axisymmetric Induction Beating System
고주파 유도 가열 장치에서 피가열체의 형상 결정
Abstract
This paper describes the process of levitation melting of metals in an axisymmetric induction heating system. This process has advantages of low heat losses, heating with short times and clean operating conditions. The shape of molten metal is determined using sensitivity analysis and optimization technique. Electromagnetic, gravitational and surface tension energies are considered, and these energies are used as an objective function in optimization process. Electromagnetic field are calculated using the finite element method. The fact that volume is constant in the process is also considered as an equality constraint.
