Abstract

Pada penelitian ini dilakukan optimasi pengaruh hubungan frekuensi dengan jumlah lilitan dan diameter koil pada proses pemanasan logam. Optimasi dilakukan untuk menghasilkan sistem pemanasan logam ferromagnetik yang cepat dan efisien. Metodologi percobaan dengan menghubungkan power supply DC 24 V 20 A ke inverter berfrekuensi tinggi. Kemudian output inverter dihubungkan dengan koil tembaga yang didalamnya terdapat spesimen logam sebagai media yang dipanaskan. Prinsip pemanasan pada logam yaitu dengan merubah arus DC power supply menjadi arus AC berfrekuensi tinggi pada koil sehingga terjadi induksi elektromagnet. Jika didalam koil ditempatkan logam ferromagnetik maka akan terjadi arus eddy didalam logam yang menimbulkan panas. Dari data yang diperoleh didapatkan temperatur tertinggi mencapai 589 0C dengan frekuensi awal 103.674 KHz pada variasi panjang koil 7 cm 10 lilitan. Sedangkan frekuensi tertinggi yang diperoleh mencapai 161.686 KHz pada variasi jumlah lilitan 6 dengan diameter 5 cm. Dari data tersebut dapat disimpulkan bahwa semakin pendek koil dan jumlah lilitan semakin banyak maka didapatkan tempeatur yang tinggi karena menghasilkan fluks magnet yang lebih banyak dan rapat. Sedangkan semakin sedikit jumlah lilitan dan diameter koil semakin kecil maka didapatkan frekuensi yang tinggi karena perbedaan panjang dari kawat tembaga.

In this research the effect of the relationship of frequency with the number of turns and diameter of coil on the metal heating process was optimized. Optimization is carried out to produce a fast and efficient ferromagnetic metal heating system. Experimental methodology by connecting DC 24 V 20 A power supply to high frequency inverters. Then the inverter output is connected with a copper coil in which there are metal specimens as heated media. The principle of heating in metals is by changing the DC current from the power supply into a high frequency AC current in the coil so that electromagnetic induction occurs. If the ferromagnetic metal is placed inside the coil there will be an eddy current in the metal which causes heat. From the data obtained obtained the highest temperature reaches 589 0C with an initial frequency of 103,674 KHz in the variation of coil length 7 cm 10 turns. While the highest frequency obtained reached 161,686 KHz in the variation of the number of turns 6 with a diameter of 5 cm. From these data it can be concluded that the shorter the coil and the greater the number of turns, the higher tempeature is obtained because it produces more magnetic flux and density. While the fewer the number of turns and the smaller the diameter of the coil, the higher frequency is obtained because of the difference in length of copper wire.
