Description

Edge over-plating removal device and steel plate plating equipment {APPARATUS FOR REMOVING DENDRITE FROM EDGE PART AND STEEL SHEET PLATING INSTALLATION}

The present invention relates to an edge overplating removal device, and more particularly to an edge overplating removal device that can remove the overplating by contacting the steel band in the edge portion of the plated steel sheet.

In general, in the steel plate process of the steelmaking process, the slab finished in the steelmaking process is rolled and annealed to manufacture a plated plate, and according to the demand of the steel plate, steel plate plating, for example, electroplating, to produce plated steel plate finished products. , Shipment. However, in the electroplating process of electroplating the surface of the steel sheet according to the order of the demand price, high current and density are generated before and after the steel sheet. In the process of over-plating occurs that the plating is more attached to the steel sheet edge than the center (center) portion of the steel sheet.

For example, in the case of performing electroplating using a carousel type plating bath, a plating bath is used. In this case, the plating bath performs the rear plating of the steel plate, and the plating bath plate the entire surface of the steel plate. Therefore, overplating at the edge of the plated steel sheet causes more thickness variation in the front and rear plating of the steel sheet, and it is necessary to remove the edge overplating of the steel sheet to prevent work delay or deterioration in the processing of the product of the electroplated steel sheet. Can be. In addition, such an edge overplating of the coated steel sheet causes a joule mark on the steel sheet, and when it is sold to the consumer in an edge overplated state, the edge overplating (powder) is dropped from the steel sheet during the painting work at the manufacturer. On the way out, it can cause various problems such as poor paint coating.
