直流电弧炉有三个主要优点: 1、能降低电极消耗达50％,这就意味着在一年内可以收回改造费用的全部投资; 2、能大大降低噪声水准,比交流电流所能达到的最低噪声水准还要小15dBA; 3、能源消耗较少。降低电极消耗 石墨电极消耗通常为尖部消耗,表层消耗和电极破损。尖部消耗为45％,表层消耗为45％,电极破损10％。 电极的尖部消耗与电极电流的平方成正比。直流电弧炉的电极电流比交流电弧炉高30％,用一根电极代替交流电弧炉的三根电极,故理论上直
DC electric arc furnace has three main advantages: 1, can reduce the electrode consumption up to 50%, which means that within one year can recover the full cost of renovation investment; 2, can greatly reduce the noise level, than the AC current can achieve the lowest noise The standard is even smaller 15dBA; 3, less energy consumption. Reduce the electrode consumption Graphite electrode consumption is usually tip consumption, surface consumption and electrode damage. The tip consumes 45%, the surface consumes 45% and the electrode breaks 10%. The tip consumption of the electrode is proportional to the square of the electrode current. DC EAF electrode current 30% higher than the AC electric arc furnace, with an electrode instead of three AC electric arc furnace, so theoretically straight
