| 摘 要： | 采用铁棒溶蚀法在工况条件下分别对300 kA和400 kA系列电流阴极炭块普通组合、高低组合以及端头槽和非端头的6台电解槽的铝液流场进行了工业测试.根据铁棒出现的正常溶蚀、"细腰"特征、溶蚀面扭转、溶蚀坑较多等现象详细地分析了槽内铝液的水平运动状态及垂直方向上的局部运动特征,并对不同结构电解槽的流速场进行了比较,沿槽大面方向,400 kA阴极炭块普通组合槽呈现大—小—小—大4个漩涡,阴极炭块高低组合槽呈现大小均匀的2个漩涡,而300 kA电解槽则呈现大小均匀的5个漩涡.

| Abstract: | Iron rod method was adopted for industrial metal flow measurement of six aluminum reduction cells.300 kA and 400 kA cells with same and different height of cathode blocks,end cell and middle cells were analyzed.The characteristics of whole horizontal flow and regional vertical flow in liquid aluminum were investigated by analyzing the phenomenon of different measured iron rods,which show normal erosion,thick-thin-thick character,turned eroded surface,numerous eroded holes.The flow velocity of the cells with... |
