摘　　要：研究了不同温度、电解残渣含量以及电解质成分下流水线镁电解槽电解质电导率的变化规律。结果表明,在MgCl2-NaCl-KCl三元体系中,温度升高、电解残渣量增加会导致电导率升高;MgO含量增加、MgCl2浓度增加会引起电导率降低;KCl含量增加、保持MgCl2浓度不变的条件下NaCl浓度增加时电导率先降低后升高。Variation laws of conductivity of flow line magnesium cell electrolyte under different temperature, different content of electrolysis residue, and electrolyte component were investigated. The results show that in MgC12-NaCI-KC1 ternary system, rising of temperature and amount of electrolytic residue will cause increase of conductivity while rising of MgO content and MgC12 concentration will cause drop of conductivity. The conductivity drops first and then rises when KC1 content increases with constant MgC12 concentration.
