Abstract
The invention relates to a strip steel electroplating anode device with a controllable electric field. The strip steel electroplating anode device comprises two rows of anode straps arranged symmetrically, wherein the anode straps located in the middle section are all connected with the positive pole of a power source through buses, two or more pairs of anode straps are located at the two ends and all are connected with a current controller and the positive pole of the power source through wires, and the current controller is connected with a strip steel side detection element. The width of the electroplating area of the anode straps in the middle section corresponds to the width of the narrowest strip steel on a production line, and the widths of the electroplating areas of the anode straps at the two ends are larger than the width of the narrowest strip steel and gradually increased until the electroplate areas of the anode straps at the two ends are wide enough to cover the widest strip steel on the production line. The strip steel electroplating anode device dynamically adjusts the distribution of the electric field of the anode straps through the current controller according to the strip steel side position signals collected by the strip steel side detection element. The problems of the electroplating fringe effect, strip steel width specification changes and deviation of the strip steel can be resolved. An edge cover is not needed. The electroplating efficiency is high.
Description
Technical field
The invention belongs to band steel electroplating device field, be specifically related to the band steel electroplating anode device that a kind of electric field is controlled.
Technical background
Under the electric field action that the plating of band steel is between anode (positive pole) and band steel (negative pole), in electroplate liquid, metal ion reduces at belt steel surface and is deposited as the process of metal.Generally, anode is connected with the positive pole of outside electroplating rectifier by bus (usually adopting copper busbar), be connected with the negative pole of outside electroplating rectifier (conductive rollers also serves the effect drawn and turn to) by conductive rollers with steel, during work, the electroplating region of anode and band steel are all arranged in the electroplate liquid of plating tank.
Generally there is following problem in the plating of band steel: 1) due to the buildup effect of electric current, and band steel edge can produce plating super thick phenomenon, affects electroplating quality; 2) production line needs the band steel of production one fixed width scope, and the change of strip width specification causes steel edge portion change in location in plating tank; 3) being with steel by having certain running deviation value during plating tank, also can causing the dynamic change of steel edge portion position in plating tank.Therefore how improving band steel edge electroplating quality, controlling thickness of coating is evenly the important topic that band steel electroplating assembly line must be considered.
At present, in order to solve the problem, common solution is:
1) according to strip width adjustment anodization sector width---the method to some extent solves the problem of plated edge effect (band steel edge super thick) and strip width specifications vary, but the problem of strip running deviation cannot be solved, the method is only applicable to soluble anode plating (for soluble anode, be difficult to changing anode), and, change the anode operation difficulty of different electroplating region width, workload is large.
2) side cover is added in band steel both sides, according to the signal of steel edge portion measuring element, the position of adjustment side cover makes it servo-actuated with steel edge portion---and the method can solve plated edge effect, the problem of strip width specifications vary and strip running deviation, but certain safe distance must be left between band steel and side cover, also a determining deviation must be stayed between side cover and anode, because this increasing the distance between anode and band steel, reduce electroplating efficiency, and, because of band steel shake or Edge shape bad, wipe the situation of touching side cover with steel to happen occasionally, wipe the bad side cover of clashing and breaking with changing difficulty, must shut down and change, reduce the operating rate of production line.
