Embodiment Construction
[0009] The embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings: a conductive joint structure of a titanium anode plate in the embodiment of the present invention, such as figure 2 As shown, the titanium joint 2 welded on the titanium substrate 1 has a copper plate 3 welded on the outer side of the titanium joint 2 . A manufacturing process of the titanium anode plate conductive joint with the above-mentioned structure is characterized in that: the titanium joint 2 and the copper plate 3 are composited by explosive welding. The embodiment of the present invention is tested on an electroplating tank for continuous electroplating of steel strips. The size of the titanium anode plate in the test tank is 1374*680*20mm, and the working current of each conductive joint is 3375A. The test results show that the two installed on it such as figure 2 The conductive joint of the titanium anode plate shown in the fig...

Abstract
The invention provides a conductive contact structure of a titanium anode plate, which is used on a continuous electrogalvanizing production line. The conductive contact structure is characterized in that a titanium contact is welded on a titanium basal plate, the outer sides of the titanium contact are welded with copper plates, and the copper plates are connected with a copper bar. The invention also provides a manufacturing process of the conductive contact structure of a titanium anode plate, which is characterized in that the titanium contact and the copper plate on the two sides are compounded by using an explosive welding process. The invention has the advantages that the copper-titanium explosive compounding is a mature and feasible technique, therefore, the metallurgical bonding can be formed after the copper-titanium compounding, the intermediate resistance can be reduced and the temperature of the conductive contact is prevented from rising too much; and the conductive contact structure has the advantages of easy manufacture and low manufacture cost.
Description
Technical field: [0001] The invention relates to the technical field of electroplating and electrolysis, in particular to a conductive joint suitable for titanium anode plates. Background technique: [0002] In the existing electroplating, electrolysis technology field, many electroplating, electrolysis equipment all adopt the anode plate that is substrate with titanium material, on titanium anode plate, be equipped with the conductive joint that is connected with power transmission copper row, this conductive joint (such as figure 1 shown) consists of a titanium connection plate welded on the titanium substrate and a copper joint welded on the titanium connection plate. Since the resistivity of titanium is much greater than that of copper, in order to reduce the contact resistance and avoid excessive temperature rise at the conductive joint, the copper joint and the titanium connecting plate are generally connected by vacuum diffusion welding. However, for titanium anode p...
