Analytical Modeling With Computer Simulation Validation Of An Inductive Heating System For Metals Melting Application
Subject area: Science,Engineering and Technology · Area of research: Electronics Engineering
Abstract
Inductive heating is a fast and environmental friendly heating method that employs eddy current resistance loses in heating of conducting materials. The eddy current being a product of magnetic induction process resulting from the electromagnetic fields generated by an induction coil powered by a high frequency voltage source. Due to the complexity of the system, the design of the induction heating systems often requires the use of mathematical and computer simulation tools which helps in shortening the development time and cost. Both analytical and computer modeling techniques were employed in this study. The analytical modeling was used in computing the electrical parameters of the induction coil that makes for optimal heating of the work-piece for any heating application while the computer modelling was used to investigate thermal dynamic characteristics of the inductively heated work piece. A 2-D axisymmetric computer model of a cylindrical graphite crucible work piece of dimensions (6cm height, 2cm external diameter and 1.5cm internal diameter) was simulated in the study with 60 Amps excitation current at 100 kHz resonant frequency. A heating temperature of about 1386oC was achieved around 600 seconds simulation time. The coil inductance of 0.03mH was obtained for analysis using copper tube coil of radius 0.5cm and coil diameter 7.5cm. The derived parameters will then be used in the fabrication of the induction heating system for experimental validation of aluminum melting process.
