传统型电解槽采用石墨化阴极炭块在生产周期内技术指标较石墨质炭块优势不明显,强化电流后的强保温节能型电解槽采用石墨化阴极炭块在生产周期内技术指标较石墨质炭块有明显优势;基于青铜峡铝业350 k A电解槽设计,石墨化阴极电解槽寿命较短,按2015年度供货价格计算,在生产周期内石墨化阴极电解槽比全石墨质阴极电解槽原铝液吨铝完全成本增加45.06元,比50%石墨质阴极电解槽铝液吨铝完全成本增加87.31元。
The traditional electrolytic cell using graphitized cathode carbon block in the production cycle technical indicators than the graphite carbon block has no obvious advantage, after strengthening the current strong thermal insulation energy-saving electrolytic cell using graphitized cathode carbon block in the production cycle technical indicators than graphite Carbon block has obvious advantages; based on the design of Qingtongxia Aluminum 350 kA electrolytic cell, the graphitized cathode electrolyzer has a short life expectancy. According to the supply price in 2015, the graphitized cathode electrolyzer has a higher capacity than the whole graphite cathode electrolyzer The original cost of tantalum aluminum tantalum increased by 45.06 yuan, which was 87.31 yuan more than that of 50% graphite cathode electrolyzer.
