Study on Influence of Insulating Clapboard in the Process of Electrolytic Cleaning for Cold-rolled Strip

摘要

Two models with and without insulating clapboard were established. The electric potential distribution and the flow of electric current in electrolytic cell under the two models were simulated by Ansoft finite element software. The results show that the distribution of equipotential surface is the most intensive in the area close to the electric plate, and the current in the cell obviously skewed flows to the bottom of the strip under the insulating clapboard model, which is important to improve the current efficiency of the electrolytic cleaning. Finally, the influence of insulating clapboard on current efficiency and under different plate spacing was carried on by experiment and analysis, proved the correctness of the simulation results.
