Problems solved by technology

[0003] At present, high-concentration nitric acid is generally used for cleaning in the production of anode beams. During cleaning, the acid mist is relatively large, polluting the environment, and cleaning is often not clean; when tinning, the tinning is uneven, and frequent leakage occurs; during casting , there will be problems such as poor molding and low yield

Abstract

The invention relates to a method for manufacturing an anode beam, which comprises the following steps of: cleaning a copper bar by using a prepared cleaning agent, hanging a stainless steel hanging lug, heating, tinning, erecting a mold, casting and shearing to produce a qualified anode beam. The process is simple to operate, clean in cleaning, uniform in tinning, high in yield and capable of manufacturing the anode beam with good quality.

Description

technical field [0001] The application type of the present invention relates to the technical field of anode beam fabrication, in particular to a fabrication method of an anode beam. Background technique [0002] In the production of zinc wet electrowinning, cathode and anode plates are generally used. The anode plate consists of two parts, the anode beam and the anode plate surface. [0003] At present, high-concentration nitric acid is generally used for cleaning in the production of anode beams. During cleaning, the acid mist is large, which pollutes the environment and often causes unclean cleaning. , there will be problems such as poor molding and low yield. SUMMARY OF THE INVENTION [0004] In order to solve or partially solve the problems existing in the related art, the present application provides a method for manufacturing an anode beam, comprising the following steps: [0005] S1. Clean the copper bar with a prepared cleaning agent, and the cleaning agent incl...
