Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to a tubular crystallizer fluid type electroplating equipment. Background Art

[0002] At present, the traditional electroplating method of continuous casting crystallizer copper tube adopts tank electroplating (immersion electroplating), which is fixed by the hanger and connected to the support structure. Figure 8 The anodes shown are combined and hung as a whole in the plating tank for electroplating. Since the outer surface of the copper tube of the crystallizer is a non-electroplating surface, the outer surface needs to be sealed with insulating tape. Its main advantage is that the electroplating equipment is simple. The main body of the equipment is a DC power supply and a plating tank. The production line investment is low and easy to build, so this electroplating method is widely used. However, the disadvantage is that the plating solution corrodes the stainless steel hanger, and the impurities of the stainless steel hanger are integrated into the plating solution. The amount of impurities formed in the plating solution increases, which reduces the conductive efficiency and thus reduces the utilization rate of the main material. This electroplating method belongs to open electroplating, and the chromium mist volatilization is large, which has a greater impact on the environment. There are many mechanical connection points, which not only affects the conductive efficiency, but also requires a large amount of assembly work. Utility Model Content
