METHOD FOR CONTROLLING THE ELECTRODES IN A FURNACE WITH FREELY BURNING ELECTRIC ARCS |
摘要 |
<p>A method for the optimum regulation of the electrodes of a three-phase electric arc furnace wherein each electrode has an associated arc voltage regulator which receives the associated arc voltage as its actual value and a desired arc voltage value as its reference value; and wherein, to form the desired arc voltage value, during each halfwave, a voltage porportional to the actual arc current and a limit value, which corresponds to the desired arc length, are provided, and the smaller momentary value, with respect to magnitude, of the current proportional voltage and of the limit value is always fed to the arc voltage regulator as the desired arc voltage value.</p> |
