technical field [0001] The invention relates to a method for designing a chemical composite plating tank system, belonging to the technical field of chemical composite plating. Background technique [0002] Magnetic abrasive finishing technology is one of the important processing methods for complex surface processing. The quality of magnetic abrasive directly affects the effect of finishing. Using chemical composite plating method can prepare high-quality magnetic abrasive with long service life. According to the preparation process of magnetic abrasives prepared by electroless composite plating and the co-deposition mechanism of the second phase, the abrasive phase needs to be dispersed and suspended in the plating solution and fully contacted with the ferromagnetic phase during the preparation process.

[0004] In the patent application CN201010145263.3, the structure of the chemical composite plating tank was optimized, and the computational fluid dynamics software was used for numerical simulation calculation, and the flow field characteristics of the plating tank before and after adding baffles were obtained. By comparing the overall flow characteristics of the plating solution, the plating The liquid flow line and the average turbulence intensity determine the optimal structure of the baffle; however, the movement and dispersion state of the plating tank after adding particles is measured by a laser particle size analyzer, and the particle size distribution in the plating solution before and after adding the baffle conditions, and then determine the optimal structural parameters of baffles, stirring paddles, etc.; use the combination of finite element simulation and test comparison to design the chemical composite plating tank structure, although it can effectively reduce the design cost and improve the scientific nature of the design, but Since the particles in the plating tank will be agglomerated and shielded during the dispersion movement, it is difficult to accurately obtain the particle distribution at each time by using a laser particle size analyzer. There will be a certain deviation in the structural parameters
