Galvanizing is to evenly coat the surface of some active metals with zinc layer, so as to reduce the oxidation speed of the metal itself. We will introduce a galvanizing method - roll plating method, so that you can better understand the knowledge of galvanized steel strip.
Roll plating is to put the strip steel to be galvanized into a special drum. When the drum is put into a tank filled with zinc plating solution, the zinc plating solution can enter the drum through the hole on the inner wall of the drum. At the beginning of transmission, the zinc plating solution will flow in and out between the inside and outside of the drum, and the position of the strip steel can be changed constantly during operation. When the holes on the drum turn from the inside to the outside, the current passing through will also reach the maximum value to realize the uniformity of galvanizing. The disadvantage of this method is that it can be applied to small galvanized strip without any decoration point.
Roll plating is a new method used in galvanizing. The disadvantage is that it is easy to miss plating for thin sheet parts. The advantage is that it greatly improves the production efficiency and makes the galvanizing more uniform.
