Description

Technical Field

[0001] This utility model relates to the field of copper sheet technology, specifically to a copper sheet for high-efficiency copper melting. Background Technology

[0002] The main purpose of using a crystallizer to extract molten copper is to transform liquid copper into solid copper products with a certain shape and size, such as plates or columns.

[0003] Copper products need to be placed in a copper dissolving tank for copper dissolution. This is done by immersing or spraying the copper products with copper sulfate solution. The purpose of dissolving copper is to increase the concentration of copper ions in the copper sulfate solution to a certain value, so as to meet the requirements of the foil production machine. In order to increase the dissolution rate of copper products in copper sulfate solution, the structure of the copper products needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a high-efficiency copper sheet for copper melting, so as to solve the problems mentioned in the background section above.

[0005] This utility model is achieved through the following technical solution:

[0006] A high-efficiency copper sheet for copper melting includes copper wire drawn from a crystallizer, the copper wire being formed into a copper sheet through a rolling process, and the surface of the copper sheet having a plurality of recesses and protrusions.

[0007] Furthermore, the recesses and protrusions located on the same end face are arranged alternately.

[0008] Furthermore, the recesses are arranged in a W-shape, and the protrusions are located in the vacant positions of the recesses.

[0009] Furthermore, the cross-sections of the recessed portion and the protruding portion are semi-circular.

[0010] Furthermore, the diameter of the recessed portion and the protruding portion is 1mm ± 0.2mm.

[0011] Furthermore, the cross-section of the copper sheet is rectangular.

[0012] The beneficial effects of this utility model are as follows: A high-efficiency copper sheet for copper melting includes copper wire drawn from a crystallizer. The copper wire is formed into a copper sheet through a rolling process. The surface of the copper sheet is provided with several recesses and protrusions. When the copper wire just extends out of the crystallizer, it is relatively soft. The copper wire is formed into a copper sheet through a rolling process, and the recesses and protrusions are formed simultaneously through rolling. Both the recesses and protrusions can increase the surface area of ​​the copper material. By increasing the contact area, the copper melting rate can be accelerated, ensuring that the copper melting rate meets the requirements of the subsequent foil production machine. In addition, the copper sheet needs to be rolled up before it can be placed into the copper melting tank. The setting of the recesses and protrusions can prevent the surfaces of adjacent copper sheets from completely adhering after the copper sheet is rolled up, leaving a gap. This allows the electrolyte in the copper melting tank to enter through the gap and react chemically with the surface of the copper sheet, increasing the contact area and accelerating the copper melting rate.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Reference Figures 1 to 2 As shown, a high-efficiency copper sheet for copper melting includes copper wires drawn from a crystallizer. The copper wires are formed into a copper sheet 1 by a rolling process. The surface of the copper sheet 1 is provided with a plurality of recesses 11 and protrusions 12.

[0019] The pressing operation is performed when the copper wire is still relatively soft and has just emerged from the crystallizer. At this stage, the copper wire has good plasticity and is prone to plastic deformation, thus requiring less force during the pressing process and making the process relatively easier to implement. Furthermore, the pressing process does not require complex equipment and tools; ordinary pressing devices can process the copper wire. This not only reduces equipment and maintenance costs but also improves the flexibility and adaptability of the production process.

[0020] By pressing copper wire into copper sheet 1, and simultaneously pressing indentation 11 and protrusion 12, both indentation 11 and protrusion 12 can increase the surface area of ​​copper material. By increasing the contact area, the copper dissolution rate can be accelerated, ensuring that the copper dissolution rate meets the requirements of subsequent foil production. In addition, the copper sheet needs to be rolled up to facilitate its placement in the copper melting tank. The indentation 11 and protrusion 12 allow the copper sheet 1 to be rolled up, especially the protrusion 12, so that the surfaces of adjacent copper sheets 1 cannot be completely adhered, leaving a gap. This allows the electrolyte in the copper melting tank to enter through the gap and react chemically with the surface of the copper sheet 1, increasing the contact area and accelerating the copper dissolution rate.

[0021] By accelerating the copper dissolution rate, the time required for the entire copper dissolution process is shortened, allowing more copper to be processed per unit time, thus improving production efficiency. For large-scale industrial production, this significantly increases capacity and productivity. Simultaneously, a higher dissolution rate and production efficiency mean more copper foil can be produced per unit time, thereby reducing production costs. Furthermore, the simpler processing method and relatively lower equipment and labor costs further reduce overall production costs.

[0022] The recesses 11 and protrusions 12 located on the same end face are arranged alternately. This alternating arrangement of recesses 11 and protrusions 12 creates a uniform distribution on the surface of the copper sheet 1, preventing localized over-density or sparseness of the recesses 11 and protrusions 12. This ensures more equal contact between different parts of the copper sheet 1 and the solution during dissolution, improving the uniformity of copper dissolution and preventing localized dissolution that is too fast or too slow, thus guaranteeing the consistency of the copper foil quality. Furthermore, the alternating arrangement of recesses 11 and protrusions 12 reduces stress concentration, thereby lowering the risk of fatigue cracks and improving the fatigue resistance of the copper sheet 1.

[0023] The recesses 11 are arranged in a W-shape, and the protrusions 12 are positioned in the empty spaces of the recesses 11. This arrangement maximizes the number of recesses 11 and protrusions 12, thereby significantly increasing the surface area of ​​the copper sheet 1. Measurements show that this design increases the copper surface area by approximately 10%, providing a larger contact area between the copper and the solution and accelerating the copper dissolution process.

[0024] The recessed portion 11 and the protruding portion 12 have semi-circular cross-sections. According to the surface area formula, the semi-circular shape of the recessed portion 11 and the protruding portion 12 can maximize the surface area of ​​the copper sheet 1, and the semi-circular shape is relatively smooth in processing, without sharp edges, which can reduce stress concentration. During the use and processing of the copper sheet 1, stress concentration may lead to material fatigue and fracture; therefore, this design helps to improve the mechanical strength and service life of the copper sheet 1.

[0025] The diameters of the recessed portion 11 and the protruding portion 12 are 1 mm ± 0.2 mm. By satisfying the above parameters, the surface area of ​​the copper sheet 1 can be maximized while ensuring the overall structural strength of the copper sheet 1, thereby increasing the contact area between the copper and the solution and accelerating the dissolution rate of the copper.

[0026] The copper sheet 1 has a rectangular cross-section. By pressing the copper wire into a rectangular cross-section copper sheet 1 with a thickness of approximately 0.8 mm, the ease of processing and manufacturing is improved, and when the copper sheet 1 is a thin plate, refer to... Figure 2 As shown, when using the pressing process, a recess 11 is formed on one end face of the copper sheet 1, and simultaneously, a protrusion 12 is formed on the other end, thereby maximizing the surface area of ​​the copper sheet 1.
