摘　　要：针对传统阴极炭块和钢棒采用炭糊扎固组装,存在水平电流大、阴极组压降高等缺陷,采用了生铁浇铸形式实现石墨化阴极炭块与钢棒组装的新式节能阴极结构技术,可有效降低水平电流及阴极压降,采用新技术后,阴极压降相比扎糊组装和高石墨质扎糊组装可分别降低50~80 mV和100~130 mV;可节电分别为200 kW·h/t·Al和350 kW·h/t·Al。Using carbon mixes compaction assembly for the traditional cathode carbon block and steel bar,it has the following defects that high horizontal current,the high-pressure drop of the cathodic unit,adopting pig iron casting to realize the new type energy saving cathode structure technology assembled by graphitized cathode carbon block and steel bar,then comparing to the carbon mixes compaction assembly and high graphite compaction assembly,the cathodic pressure drop was decreased by 50~80 mV and 100~130 mV separately;it can save electricity 200 kW·h/t·Al and 350 kW·h/t·Al separately.
