Problems solved by technology

[0006] The present invention aims to solve the problem that the cast aluminum cathode plate used in the existing zinc electrolysis process has brittleness, poor surface finish, difficult peeling of the electrolytic zinc plate, short service life, and the welding stress of the cathode plate of the calendered aluminum plate welded plate girder. Cathode plates are easily deformed, resulting in uneven arrangement of cathode plates in the electrolytic cell, wasting electricity, affecting electrolysis output and quality and other technical problems. An aluminum calendered plate fused cast plate beam-type cathode plate is provided, which includes aluminum calendered plates. The end beam of the calendered plate at one end of the aluminum calendered plate is melted with the plate beam (3) formed by melting the molten aluminum in the mold after melting the surface of the joint part (2) of the aluminum calendered plate end beam by an electric induction method As a whole; by injecting aluminum liquid into the mold to wrap the copper conductive block in the mold, the copper conductive block and the plate beam are melted and cast as one, and after the solidification and unloading of the mold, the copper and aluminum joints of the copper conductive block are locally brazed and strengthened

preparation example Construction

[0016] The preparation method of this cathode plate is realized through the following steps:

[0017] 1) Cut the aluminum calendered plate 1 according to the required size, and the length dimension includes the joint part (2) with the plate beam (3);

[0018] 2) Extend the joint part (2) of the end beam of the calendered plate into the special mold with long holes;

[0019] 3) Use the electric induction method to melt the surface of the joint part (2) of the end beam of the rolled plate in the mold, and the melting depth is ≥ 1mm, and then inject the molten aluminum that has been melted in advance, so that the joint part of the end beam of the rolled plate after the surface is melted ( 2) It is integrated with the plate girder (3) formed by molten aluminum;

[0020] 4) Place the copper conductive block 4 with embedded parts in a fixed position in the mold in advance, pour aluminum liquid into the mold to wrap the copper conductive block, and make the copper conductive block 4...

Embodiment

[0025] For the cathode plate of the calendered aluminum plate welded plate girder, the welding stress makes the cathode plate and the plate girder easy to deform, making the gap between the cathode plates in the electrolytic cell uneven, wasting electricity, and affecting the output and quality of electrolysis. The aluminum calendered plate developed in this paper The solution of cast plate beam type cathode plate is:

[0026] Both the aluminum calendered plate 1 and the plate girder 3 are made of materials with chemical properties resistant to electrolytic zinc liquid and excellent electrical conductivity: 1A97 grade is used for the aluminum calendered plate, and 1A97 grade is also selected for the plate girder material. Specific preparation process:

[0027] First process the aluminum cathode plate 1 according to the required size, and its size length should include the joint part 2 with the plate girder 3; according to the size of the plate girder, the end beam part with th...

Abstract

The invention discloses an aluminum calendering plate and plate beam casting type cathode plate, which is developed to solve the technical problems that the traditional casting molding aluminum cathode plate for zinc electrolysis has the defects of plate crispness, poor surface finish, difficulty in stripping an electrolytic zinc plate and short service life of, the calendering aluminum plate andplate beam welding type cathode plate has the defects of non-uniform arrangement gaps of the cathode plate in an electrolytic bath, waste of electric energy, and influences on the electrolysis yield and quality caused by easiness in deformation of the cathode plate due to welding stress, and the like. The solution provided by the invention comprises the following steps of: making an end beam partof a calendering plate cut according to a required size extend into a mold; making the surface melting depths of both sides of the end beam of the calendering plate more than or equal to 1 millimeterby adopting an electric induction method; injecting molten aluminum liquid; casting and solidifying the surface molten part of the end beam and the aluminum liquid injected into the mold into a whole; integrally coating a copper conducting block with the aluminum liquid injected into the mold; and performing local braze welding on the copper conducting block for reinforcement after solidificationand mold unloading. The cathode plate has the advantages of bonding firmness, no gaps, high electric conductivity, no deformation, high power utilization ratio in the zinc electrolysis process and long service life, and is beneficial to enhancement of the electrolysis yield and the electrolysis quality.

Description

Technical field: [0001] The invention relates to an aluminum cathode plate used in the heavy nonferrous metal zinc electrolysis process, in particular to an aluminum rolled plate fused cast plate beam type cathode plate used in the heavy nonferrous metal zinc electrolysis process. Background technique: [0002] There have been two manufacturing forms of aluminum cathode plates used in the heavy non-ferrous metal zinc electrolysis process at home and abroad: [0003] 1. Cast aluminum cathode plate has disadvantages: low forming rate, brittle and easy to crack, poor surface finish, difficult peeling of electrolytic zinc plate, and short service life. [0004] 2. Use the calendered aluminum plate, and then weld the plate girder by welding. Its disadvantages: there is stress in the welding place, which makes the plate girder prone to lateral and end deformation, and makes the gap between the cathode plates in the electrolytic cell uneven. , causing waste of electric energy in t...
