Design and manufacture method of anode box of electrogalvanizing unit

Abstract

The invention discloses a designing and manufacturing method of an anode box of an electrogalvanizing unit. The designing and manufacturing method of the anode box of the electrogalvanizing unit comprises the following steps that a box body internal flow channel, a liquid inlet pipe internal flow channel, a liquid outlet pipe internal flow channel and a box type ribbed plate are manufactured; the box body internal flow channel, the liquid inlet pipe internal flow channel and the liquid outlet pipe internal flow channel are embedded into the box type ribbed plate; and fibers are wound on the outer surfaces of the box body internal flow channel, the liquid inlet pipe internal flow channel and the liquid outlet pipe internal flow channel layer by layer, and thus the anode box of the electrogalvanizing unit is obtained. The designing and manufacturing method of the anode box of the electrogalvanizing unit has the advantages that the anode box manufactured through the designing and manufacturing method has good compactness and is high in overall strength and not prone to deformation in an alternate cooling and heating environment; the internal flow channels do not peel off when scoured by electroplate liquid; and the designing and manufacturing method is suitable for manufacturing the anode box under the conditions of large cold and heat changes and long-term high-load production.

Description

technical field [0001] The invention relates to a method for designing and manufacturing an anode box of an electrogalvanizing unit, belonging to the technical field of galvanizing equipment. Background technique [0002] In the actual production of cold rolling, the cold rolling strip electroplating unit currently mainly adopts two groove types: horizontal type and vertical type. In the circuit design of the vertical plating tank, the steel strip is the cathode, and the anode is installed on a special device called the anode box. In the vertical plating tank, the anode boxes are used in pairs, and a potential difference is formed between the strip steel and the anode plates on the anode boxes on both sides of the strip steel, and the electroplating on the surface of the strip steel is realized through the movement and adhesion of the metal inside the electroplating bath. The anode box is composed of liquid inlet pipe, plating solution overflow port, multi-layer orifice pla...

Problems solved by technology

[0006] To sum up, the disadvantages of the existing anode box manufacturing process: (1) the inner and outer surfaces of the runners are coated with phenolic resin layer, after long-term work in alternating cold and hot environments, the phenolic resin layer peels off; (2) the box body and other After each component is manufactured separately, the whole anode box is formed by bonding method, which is lacking in mechanical strength and rigidity
