Study Of Multi-physical Fields Numerical Simulation Of Copper Electrolysis

As the increasing number demand of the electrolytic copper, there is an urgent problem to solve that how to produce high quality of refined copper in high efficiency. There are a variety of physical fields such as electric field, magnetic field and flow field produce different degree effect on the cathode copper starting sheet deformation in the process of copper electrolytic refining. And this kind of deformation mainly exist on the first cycle of copper electrolysis, it is important for the unit reshaping and the staff straighten deformation if we could master the extents of the copper starting sheet deformation that all kinds of physical fields acts and develop the deformation position of the cathode copper starting sheet.Therefore, The cathode copper in conventional electrolysis way in some large-sized smelting factory has been researched subject. On the foundation of the domestic and international studies, A study has been conducted the electrolysis anaplastic facilities and the varieties of physical field during the electrolysis process. Firstly, to be specific, the research approaches consist of calculation and analysis of current intensity, flow models, flow rate of electrolyte and so on. Secondly, the mechanical property tests and measurement thickness of the cathode copper are designed for obtaining the parameters of simulation experiments such as the Elastic Modulus, Poisson’s ratio and the average thickness of the copper. Lastly, the finite element software COMSOL is used to establish the simplified simulation model of cathode and anode plate and electrolyte. Moreover, the author utilizes the simplified simulation model to calculate the size and distribution of stress filed, flow filed and magnetic field after the first electrolysis cycle.Through the groove surface observation experiment, the results of the deformation position and the size of the simulation strain field are verified. The simulating strain results can instruct the copper starting sheet shaping equipment and the staff to straighten the plastic deformation. The foregoing research finds out that after the first cycle of electrolysis, the cathode copper in the corner position has the maximum deformation and the deformation amount is 15mm.This paper proposes to add a horizontal vibration flat shaping equipment to plastic copper starting plate, and to instruct the staffs of the electrolytic groove and considerably increase the production efficiency.
