Horizontal electroplating bath and electroplating zone negative and positive pole gap automatic compensation method

Abstract

The invention provides a horizontal electroplating bath including a conductive roller (2), a conductive supporting roller (3) and a positive pole plate (4), the conductive roller (2) is used for transmission of a strip steel (1) and conduction of cathodic current in the electroplating process, the conductive supporting roller (3) is used for compacting the strip steel (1) and the conductive roller (2), the horizontal electroplating bath is characterized by also including a tilting device, the tilting device comprises a pivot (6) located at the positive pole plate end, under the action of a lifting device (7), the positive pole plate (4) can pivot around the pivot (6) to change the relative position of the positive pole plate (4) and the strip steel (1). The invention provides an electroplating zone negative and positive pole gap automatic compensation method of the horizontal electroplating bath, delta automatic compensation can be realized by regulating the tilting device according to gap compensation amount DELTA (delta) = D-delta. The electroplating zone negative and positive pole gap automatic compensation method realizes the real-time compensation of a negative and positive pole gap so as to avoid the direct contact of negative and positive poles, mechanical damages and electrical short circuit and realize smooth running of the electroplating process.

Description

technical field [0001] The invention belongs to the field of cold-rolled thin strip steel production, and in particular relates to a horizontal electroplating tank adopted for surface electroplating of cold-rolled thin strip steel and a method for automatically compensating the cathode and anode gaps in the electroplating area. Background technique [0002] The continuous electroplating line for the surface of cold-rolled strip steel currently used in the industrial field, such as the continuous electrogalvanizing line for the surface of thin strip steel, can be divided into horizontal electroplating tanks and vertical electroplating tanks according to the orientation of the electroplating area. Among them, the horizontal electroplating tank has a compact structure, and the strip passes through the electroplating area horizontally, which is suitable for electroplating of high-strength and thick-spec strip steel. There are typically two types of horizontal plating tanks that ...

Problems solved by technology

[0007] In summary, the disadvantage of the existing horizontal electroplating tank is that the influence of the sag produced by the cold-rolled thin strip’s self-weight on the distance of the electroplating area is not considered in the design, and there is no corresponding adjustment function, resulting in the cold-rolled thin strip used as the cathode. The distance between the strip steel and the anode plate as the anode will change, and there will be hidden dangers of mechanical abrasion and electrical short circuit

At the same time, the sag produced by the cold-rolled thin strip under the action of its own weight will reduce the electroplating efficiency, increase energy consumption, reduce product quality, and hinder the electroplating process.
