METHOD FOR MELTIN METAL IN AN INDUCTION PLASMA FURNACE |
摘要 |
<p>A method for melting a metal in an induction plasma furnace consists in melting the metal (2) by means of the plasma arc (8) and the magnetic field of the inductor (4) and in effecting an interaction between the plasma arc (8) and the magnetic field of the inductor (4), this interaction being accompanied by fluctuations in the energy parameters of the plasma arc (8) and by the appearance of an acoustic pressure. Then, the values of the energy parameters of the plasma arc (8) are analised and compared with the preset values of the energy parameters of the plasma arc (8). At the same time, the acoustic pressure level is measured at each moment of its appearance during the interaction of the plasma arc (8) with the magnetic field of the inductor (4) while the plasma arc (8) is penetrating into the melted metal (2), and the intensity of the magnetic field of the inductor (4) is reduced until the acoustic pressure is eliminated.</p> |
