At present, when electrolytic copper foil is produced in China, lead-antimony alloy, lead-silver alloy or titanium-coated iridium is mostly adopted as an anode plate. Under the influence of long-time, large-current and high-corrosion environment, the alloy anode plate is corroded more and more, so that the electrode distance is continuously increased, the cell voltage is increased, the power consumption is increased, the surface density uniformity of the copper foil is poor, and the alloy anode plate is basically eliminated; DSA coating service life of the titanium-coated iridium anode plate: the corrosion resistance is more than or equal to 40000KAh, the corrosion resistance is several times of that of the alloy anode plate, the replacement period is 1-2 times per year, and the anode plate is assembled on the inner arc surface of the anode groove in an embedded manner, namely 600 plus 800M 8 titanium screws are fixed on the inner arc of the anode groove (the screws are densely distributed). The service life of the anode tank is at least 15 years, and the periodical replacement of the anode plate easily causes the wire holes in the anode tank to generate sliding wires, so that the fixing precision of the anode plate is influenced, and the anode tank (the anode tank is made of titanium and is expensive) is scrapped in advance; the electrolyte in the anode tank is very corrosive and has a certain temperature, if the anode tank is externally fixed, the anode tank needs very high sealing performance, and once the sealing effect is poor, the electrolyte leaks and crystallizes, so that the environment is seriously polluted.
