KR950018685A - Radial Electroplating Apparatus and Plating Method - Google Patents

Abstract

The present invention relates to an electroplating apparatus for a metal strip and a plating method thereof, and more particularly, to a radial plating apparatus for electroplating zinc or another metal on one surface of a metal strip and a method for manufacturing an electrogalvanized steel sheet using the same. It is about. According to the present invention a disadvantage of the known method for radial cells using a conductor ring wound on a drum is the deterioration of the mechanical properties of the strip and the step of the conductor ring and elastomer due to the large traction force on the strip. It is possible to prevent defects such as band marks and arc spots. In addition, the present invention can prevent surface contamination of the strip on the deflector roll by removing the plating liquid from the plating cell that rises on the strip surface as the strip progresses from the plating cell by disposing the conductor roll and the backup roll between the drum and the deflector roll. The plating apparatus according to the present invention can use both a soluble anode-chloride bath system and an insoluble anode-sulphate jade system, and can increase productivity by increasing the circulation speed of the strip by arranging a plurality of cells.
