A kind of soluble anode electroplating device and electroplating method thereof

Abstract

The invention provides a soluble anode electroplating device, comprising an electroplating tank, a sinking roller is installed at the bottom of the electroplating tank for steering the steel strip, and a pair of soluble anode strip brackets are respectively installed on both sides of the sinking roller on the upper part of the electroplating tank, A number of soluble anode strips are suspended on the soluble anode strip bracket, and edge covers are installed between the soluble anode strips at both ends of each pair of soluble anode strip brackets, and guide rails are installed inside the electroplating tank, and the edge covers are slidably connected to the guide rails. The hood moves along the width of the strip on guide rails. The present invention also provides the electroplating method of the electroplating device. By introducing the edge cover and making a reasonable production plan, the adaptability of the soluble anode production process to the strip width is improved, the operation of frequently replacing the number of anode strips is reduced, and the work is saved. time, reduce work intensity and improve work efficiency.

Description

technical field [0001] The invention relates to an electroplating device, in particular to a soluble anode electroplating device and an electroplating method, which can adapt to the problem of strip width variation or strip deviation. Background technique [0002] Electroplated tinplate is widely used in metal packaging. At present, the production methods of commodity electroplated tinplate include soluble anode method and insoluble anode method. The use of insoluble anodes to produce electroplated tin can achieve better coating quality, thinner coatings, better production environments and more flexible operating systems. However, the use of soluble anodes to produce electroplated tin has low unit construction costs and low production costs for tinplates. Therefore, in the current tinplate production process, soluble anodic tin plating and insoluble anodic tin plating have their own markets. Among them, most of Japan adopts insoluble anode technology, and most of Europe an...

Problems solved by technology

As a result, the problem of inflexible tinplate production system and the increased labor intensity caused by frequent replacement of the plate width

In addition, although changing the plate width can improve the problem of edge thickening, it cannot fundamentally eliminate the problem of edge thickening

[0005] (2) The change of the plate width is not continuous, and its increase or decrease is limited by the plate width. However, the change of the strip width is continuous. In order to adapt to the change of the strip width, it can be adjusted by adjusting the Spacing to accommodate small changes in strip width, which will increase the non-uniformity of coating thickness in the strip width direction

[0006] (3) The pole plate is fixed during the production process, and the strip steel runs on the center line of the unit as the benchmark; however, during the production process, the strip steel runs at high speed and long distances, and it is inevitable to deviate

In the soluble anode tin plating tank of the transmission, after the strip steel runs off, the thickness uniformity of the electroplating coating will definitely decrease, and there may even be a possibility of missing plating
