一、现状与差距 1.自焙电解槽。我国早期建设的铝厂都采用侧部导电自焙阳极铝电解槽。此种槽型是我国50年代初由前苏联引进的,通过多年的改造和发展,机械化水平和技术经济指标都有较大提高。槽容量在60～80KA(电流强度),直流电耗14800～16500度/吨铝,电流效率在86～90%。阳极采用中温沥青糊,但环保问题突出。与国外相比其差距是:机械化水平低,没有专用的拔棒、钉棒、母线转接等
First, the status quo and the gap 1. Self-baking electrolyzer. China’s early construction of aluminum smelters have adopted the side of the self-baking anode aluminum electrolytic cell. This type of trough was introduced by the former Soviet Union in early 1950s. After years of reform and development, the mechanization level and technical and economic indicators have greatly increased. Slot capacity of 60 ~ 80KA (current strength), DC power consumption 14800 ~ 16500 degrees / ton of aluminum, the current efficiency of 86 to 90%. Anodic use of temperature asphalt paste, but outstanding environmental problems. Compared with foreign disparity is: low level of mechanization, there is no special pull bar, nail bar, bus adapter, etc.
