设计了一台3000A液态下阴极电解槽,阴极为轧制钨板设置在槽底部,电解过程中阴极表面形成一层金属液面充当液态阴极作用,继续析出的金属流入坩埚中,阳极为方块状石墨块,由导杆悬挂于可升降的水平导电母线上,阴极处于阳极投影下方,阴阳极之间水平平行布置。在此设计的电解槽上进行金属钕的电解试验,电解槽稳定运行,电解槽电压与传统上插阴阳极式电解槽相比,槽电压大幅降低至6 V以内,电流效率达到80%以上,本文还考察了该电解槽的电压分布情况、电流电压曲线、电解槽的热场分布情况。
A 3000A cathode cathodic cell was designed. The cathodes were rolled tungsten plates at the bottom of the cell. During the electrolysis process, a layer of metal was formed on the cathode surface to act as a liquid cathode. The precipitated metal flowed into the crucible. The anode was a square Graphite block, by the guide rod hanging on the horizontal conductive bus can be raised and lowered, the cathode is located below the anode projection, between the anode and cathode horizontal parallel arrangement. In this design of the electrolytic cell electrolysis of neodymium metal electrolysis test, stable operation of the cell, the cell voltage and insertion of the traditional anode and cathode electrolysis cell compared to significantly reduce the tank voltage to less than 6 V, the current efficiency of 80% or more, The paper also examines the voltage distribution of the cell, the current and voltage curves, and the thermal field distribution of the cell.
