几年来,我厂电炉自焙电极,无论是开炉、炉烘,还是电极发生事故再重新焙烧,都是用重油焙烧,为国家节约了大量木材和电。我们把这方面经验介绍一下,供各兄弟厂参考。我厂101~#、102~#炉是密封式粗炼电炉,变压器功率为8000KVA,电极直径为800m/m(原来是870m/m),原为援阿试验时冶炼镍铁和生铁用的。在援阿试验时,由于生产工艺等种种原因,造成电极软断、硬断的次数很多,尤其是102炉。从68～70年电极硬断100多次,软断也达几十次之多。这样,烘电极次数也很多。按照过去老
Over the past few years, our factory self-baking electrode furnace, whether it is open furnace, oven drying, or the electrode accident and then re-roasting, are roasted with heavy oil, for the country to save a lot of wood and electricity. We introduce this experience to the brothers for reference. Our factory 101 ~ #, 102 ~ # furnace is a sealed smelting furnace, the transformer power is 8000KVA, the electrode diameter is 800m / m (originally 870m / m), originally used for smelting ferronickel and pig iron. Aid in aid test, due to various reasons such as the production process, resulting in the electrode soft off, a lot of hard off, especially 102 furnaces. Electrodes from 68 to 70 years hard off more than 100 times, soft off up to dozens of times. In this way, the number of baking electrodes are also many. According to the past old
