在苏联第九个五年计划期间,诺里尔斯克联合企业由于增加了新的生产能力,同时强化了电解过程,电解镍产量得以增长。在1971年以前,电解槽的生产能力主要靠增加槽中电极数量(缩小电极间距)来提高。其后用提高电流密度来提高电解槽生产能力(表1,2)。生产槽的平均电流密度由233安/米~2提高到285～289安/米~2,在个别周期内电解在电流密度300～310安/米~2下进行,电解槽的生产能力提高28.2%。
During the Ninth Five-Year Plan of the Soviet Union Norilsk conglomerates increased electrolytic nickel production due to the addition of new production capacity and the strengthening of the electrolysis process. Before 1971, the capacity of the cell increased mainly by increasing the number of electrodes in the cell (reducing electrode spacing). Subsequent increases in current density to improve cell productivity (Table 1, 2). The average current density of the production tank was increased from 233A / m ~ 2 to 285 ~ 289A / m ~ 2. The electrolysis was carried out at a current density of 300 ~ 310A / m ~ 2 in a few cycles and the production capacity of the electrolytic cell increased by 28.2 %.
