Description
Technical Field
[0001] The utility model relates to the technical field of electrogalvanizing, in particular to automatic dehydrogenation equipment for electrogalvanizing. Background Art
[0002] Galvanizing is a commonly used anti-corrosion method. It achieves the anti-corrosion effect by coating a layer of zinc on the steel surface to form an alloy layer between zinc and steel. However, during the galvanizing process, hydrogen will be generated on the steel surface. If the hydrogen cannot be discharged or treated in time, it will cause hydrogen embrittlement on the steel surface, thus affecting the quality and performance of the product. In order to prevent hydrogen embrittlement on the steel surface, galvanizing dehydrogenation treatment is required. Therefore, after electroplating, heat treatment at a certain temperature for several hours is required to drive out hydrogen that has penetrated into the coating or the base metal.
