Strip correction device for electroplating process

Abstract

The invention relates to an electroplating procedure strip steel deviation correction device which comprises a strip steel position detection mechanism, an interconnected control mechanism and two magnet mechanisms. The two magnet mechanisms are arranged on the two sides of the center line of a unit respectively. Each magnet mechanism comprises at least one magnet. The magnetic field directions of all the magnets are all perpendicular to the surface of strip steel, and the magnets on the two sides are opposite in magnetic field direction. All the magnets are connected with drive mechanisms driving the magnets to get close to or away from the surface of the strip steel. The strip steel position detection mechanism and all the drive mechanisms are connected with the interconnected control mechanism. The magnets are arranged to apply a magnetic field to the powered strip steel so as to obtain Ampere force opposite to the deviation direction, and therefore deviation correction is carried out on the steel strip under the condition that the magnets are not in contact with the strip steel, strip steel deviation correction control in an electroplating tank is achieved, and the product quality of an electroplating unit can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a deviation correcting device for strip steel in an electroplating process. Background technique [0002] In the strip continuous production unit, the strip often deviates from the center line of the unit during operation, that is, the strip runs off-track, which brings difficulties to production. Therefore, the unit will set up a set of deviation correction system at intervals. By changing the position of the deviation correction roller, the deviation strip will return to the center position under the action of friction, so as to ensure the stable operation of the strip. [0003] Electroplating is currently the most widely used metal protection process. Electroplating is an electrochemical process, that is, the process of depositing a desired metal or alloy layer on a metal or non-metal substrate by electrolysis. Electroplating can change the appear...

AI Technical Summary

Problems solved by technology

Since the electroplating tank is usually very long and there are many roll systems, the strip is easy to run off during operation

However, if a conventional correction roller is installed in the tank, the surface of the correction roller needs to be in contact with the strip steel when the strip runs off, which will directly affect the surface quality of the coating. Therefore, the correction system is usually only installed at the entrance and exit of the electroplating tank.

This is the bottleneck of the process control of the strip steel electroplating section, which seriously affects the quality of the finished product of the electroplating unit
