Study on Polarization of the Cold-rolled Steel Strip in the Process of Electrolytic Cleaning
The electrochemical behaviors of the cold-rolled steel strip were investigated at the range of ordinary current density (10A/dm2-30A/dm2).The power consumption,which is caused by overpotential of the cold-rolled steel strip per unit area (PCOC),was used to evaluate the energy consumption which is caused by polarization effectively.The effects of electrolysis time,current density,temperature and the concentration of electrolyte on the PCOC were examined.The PCOC increased with time,but the growth rate of the PCOC decreased with time.After about 8 seconds,the increasing rate of the PCOC closed to zero.The value of the PCOC was in direct proportion to current density,and there was a significant increase when the current density is beyond 25A/dm2.Both raising temperature and increasing the concentration of electrolyte are effective ways of decreasing the PCOC.
