铁合金埋弧电炉是耗能很大的设备。以16.5MVA炉子为例,日耗电达32万度。铁合金电炉的供电控制是生产中的关键问题。目前国内基本上是用人工根据电流大小升降电极的方法来控制供电的。由于电路中高电
Ferroalloy submerged arc furnace is a great energy consumption equipment. To 16.5MVA stove, for example, daily consumption of 320,000 degrees. Ferroalloy furnace power supply control is a key issue in production. At present, the basic method is to control the power supply by manually raising and lowering the electrodes according to the current size. Due to high power circuit
