Description

Technical Field

[0001] The utility model belongs to the field of electroplating and relates to an anode basket device for continuous electroplating. Background Art

[0002] In the current high-speed continuous electroplating production line for steel strips, the working tank structure of the electroplating section usually adopts a vertical tank structure. The titanium basket, as an anode component, is a flat rectangular container for holding anode balls / blocks, and also plays the role of introducing power into the anode balls / blocks. The titanium basket (anode) is installed parallel to the steel strip (cathode). The anode balls / blocks are dissolved into the electroplating solution through the anode power supply, and the metal cations are deposited on the steel strip (cathode), and the steel strip completes the electroplating process.

[0003] The electroplating production line has a high speed and high output, which requires the use of high current density for electroplating operations. However, traditional equipment and processes cannot meet the requirements of high current electroplating, which will cause the anode material to passivate and the titanium basket to oxidize, thus terminating production. Conventional titanium baskets use conductive rods to increase the conductivity of the titanium basket and the electrochemical dissolution of the anode material. However, due to the concentration effect of the current in the conductive rod, the electric field in the titanium basket is uneven, and the uniformity of the coating will also be affected.

[0004] In the prior art, there is an invention of a platinum-plated anode titanium basket, which solves the conductivity and electric field uniformity of the titanium basket, so that the titanium basket can meet the requirements of high current density work and finally obtain a coating with uniform thickness. In addition, the platinum coating has good corrosion resistance and can effectively guarantee the corrosion resistance of the titanium basket. However, this solution has high cost, complex process and complex maintenance. Utility Model Content

While enhancing the conductivity of the titanium basket, the titanium-coated copper side plate and bottom plate are used to enable the titanium basket to provide a uniform and stable electric field during the electroplating process. At the same time, the entire titanium basket (anode) and the strip steel (cathode) are positioned by upper and lower guides to ensure parallelism, so that the speed of metal deposition on the steel strip is uniform, the coating thickness is consistent, and the coating thickness uniformity can be controlled within 5%;

[0018] The entire titanium basket conductive joint of this scheme is closely connected, the maximum current can reach 10000A, and the current density can be increased to 30A / dm 2 The above greatly improves the current density, thereby increasing the unit speed of the strip steel continuous electroplating line.
