In this paper, at first, a simulation of induction furnace model optimized resonant capacitor is designed for a practical induction furnace with parallel resonant inverter. Then rectifier and inverter snubber circuit are designed. And taken voltage, current, THD and power measured. This measured value comparison with actual working industry furnace data. and conclude that when furnace is not operate at full load that time its power factor is very low. And THD is high.

A new two-coil crucible induction furnace with a lateral coil connected to the one-phase electric power supply and a bottom coil connected to a capacitor bank with an appropriate value of the capacity is able to realize a desired balance between the induction heating of the lateral face and of the bottom face of the furnace bath. The evaluation of the optimum value of the capacity, which corresponds to the same mean value of the induced power density on the respective faces, represents an example of simulation-driven optimal design. Finite element models are used to study many variants of the new furnace related the number of turns of the two coils and related the diameter of the furnace bath for imposed bath volume.

Steel is an essential material for sustainable development for people to satisfy their needs and aspirations. It is a part of people’s everyday life, in both the developed and developing world. It is used for various purposes like transportation, enabling healthcare, supplying water, delivering energy etc. Now-a-days demand of steel is increasing due to increased in infrastructure and globalization. And to meet this demand we are looking for such foundry process which will produce high quality steel with minimum time. The aim of this paper is to improve the overall performance of induction furnace and to improve melt rate with optimum use of electricity. This paper mainly put attention on induction furnace as these are main consumer of electricity in foundry. In case of induction furnace efficiency is sensitive to many controllable features lie in operational practices ,coil height, charge mix, furnace utilization etc. So with the help of recommendation ,it is easy to find out the w.

Abstrak Pemanasan induksi merupakan sebuah proses pemanasan yang ramah lingkungan karena proses pemanasannya yang tidak saling bersentuhan antar medianya. Ada banyak jenis pemanasan induksi yang digunakan untuk aplikasi rumah tangga, tapi ini masih merupakan teknologi yang baru di Indonesia. Permasalahan yang menarik dalam mendesain pemanasan induksi yaitu masalah effisiensi dari pemakaian energi dan pemilihan dari material plat. Perangkat lunak COMSOL ® Multiphysics digunakan untuk mensimulasikan dan mempresentasikan dari proses pemanasan induksi ini. Perangkat lunak ini dapat digunakan untuk mendesain pemanasan induksi yang mempunyai effisiensi yang bagus. Dalam makalah ini parameter-parameter yang mempengaruhi dalam desain proses pemanasan induksi akan disimulasikan dan dianalisa seperti pengaruh dari lebar plat induktor, jarak antar induktor, dan jenis dari material plat. Berdasarkan dari simulasikan ini terlihat bahwa sebuah desain yang baik dari pemanasan induksi harus mempunyai lebar dan jarak antar induktor yang pendek dan menggunakan plat material dari silicon carbide dengan menggunakan pengontrolan frekuensi tinggi. Kata kunci: COMSOL, plat penghantar, analisa efisiensi, pemanasan induksi Abstract Induction heating is clean environmental heating process due to a non-contact heating process. There is lots of the induction heating type that be used in the home appliance but it is still new technology in Indonesia. The main interesting area of the induction heating design is the efficiency of the usage of energy and choice of the plate material. COMSOL ® Multiphysics Software can be used to simulate and estimate the induction heating process. Therefore, the software can be used to design the induction heating process that will have a optimum efficiency. The properties of the induction heating design were also simulated and analyzed such as effect of inductor's width, inductor's distance, and conductive plate material. The result was shown that the good design of induction heating must have a short width and distance inductor and used silicon carbide as material plate with high frequency controller.

In this paper, a lumped-parameter model is presented, allowing to calculate the power consumption of a furnace of a given shape. In this model, judicious use was made of a number of approximations, so that it turned out to be analytically solvable, which task was performed by Mathematica. In order to simplify the resulting software package, and make it cheaper and easier to use, a polynomial approximation of the model was then calculated and implemented in Excel. The resulting software seems to fulfill its promises; in particular, an accuracy better than 10% is achieved, which is perfectly acceptable for its intended purpose (assisting in the furnace feasibility study phase, where easiness and rapidity of use tend to be the most important factors).
