Electrode for cold-rolling strip steel electrolytic cleaning

Abstract

The invention relates to an electrode for cold-rolling strip steel electrolytic cleaning. The electrode for cold-rolling strip steel electrolytic cleaning is characterized by comprising a fixed power pin, a movable power pin, a polar plate and a copper bar, wherein the outer layer of the copper bar is provided with line with rubber; the copper bar is in a U shape and penetrates through the fixed power pin; the fixed power pin is connected with the upper part of the movable power pin through a corrosion-resistant bolt; and the lower end of the movable power pin is welded on the polar plate. The polar plate can be easily detached, and the polar plate is convenient to replace and maintain.

Description

technical field [0001] The invention relates to an electrode for electrolytic cleaning of cold-rolled strip steel. Background technique [0002] The surface of the cold-rolled steel strip has a lot of residues, mainly rolling oil, iron powder, etc. The existence of these residues will have an adverse effect on the subsequent process, so the surface of the cold-rolled steel strip must be cleaned . The cleaning process is generally a combined multi-stage intensive cleaning including alkaline cleaning, alkaline scrubbing, electrolytic cleaning, water scrubbing, and water rinsing. In order to improve the cleanliness of the cold-rolled strip surface, most of the modern cold-rolled strip cleaning processes will incorporate electrolytic cleaning technology, in order to effectively remove the residual dirt that is difficult to remove by other cleaning methods and still remain in the tiny pits on the strip surface , so as to obtain high-quality cold-rolled strip steel.

AI Technical Summary

Problems solved by technology

Due to the narrow space in the tank and the harsh operating environment, it is not conducive to the replacement operation; at the same time, it is easy to damage the rubber lining in the tank due to inadvertent welding, thus reducing the life of the tank.

[0005] In addition, in the previous design of the electrolytic cell, the power pins generally use L-shaped steel, and the welding with the angle steel is a single-point contact. During use, corrosion may easily lead to poor contact between some plates and power pins, and the current cannot be conducted well. to the plate, so that the electrolytic effect cannot occur, and accordingly the average current density on the plate is too large, which affects the distribution of current
