中文摘要: 采用熔盐电解法一步合金化直接制取铝锶合金,同时采用了复合电极,阳极析出的氯气得以顺利逸出,而且阴阳极引线得到很好的保护,从而使电解过程能够顺利进行。电解条件:750 ℃、阴极电流密度1.0 A/cm2、电解质配比(SrCl2 70%、KCl 25%、SrF2 5%)、极距4.0 cm,阴极产品Al-Sr合金含Sr 10%、Ca、Fe均小于0.1%,电流效率82.6%,直流电耗998 kWh/t,成本25 022元/t。
Abstract:Al-Sr alloy was directly prepared by fused salt electrolysis process applying combined electrodes. Chlorine gas separated from anode smoothly escaped, and cathode and anode leading wires were well protected, so that electrolysis process could proceed smoothly. Electrolysis is carried out at 750 ℃, DK=1.0 A/cm2, electrolyte ratio (SrCl2 70%, KCl 25%, SrF2 5%), and polar distance of 4.0 cm. The cathode product Al-Sr alloy contains Sr 10% and both Ca and Fe of 0.1% below. The current efficiency is 82.6 %, DC power consumption is 998 kWh/t, and production cost is 25 022 RMB/t.
