Problems solved by technology

[0003] In the existing copper melting production, the efficiency of copper melting is too low, and it is required to manually adjust the feeding speed according to the current copper melting speed, so that the space of the copper melting device can be fully utilized, but the manual operation error is large, and the operation is not timely. Moreover, the workload is heavy, the production cost is increased, and the function of improving production efficiency cannot be achieved. Therefore, we propose a material process for electrolytic copper foil melting copper that reduces energy consumption to solve the above-mentioned problems.

Embodiment 1

[0035] refer to Figure 1-6 , an electrolytic copper foil dissolving copper material process for reducing energy consumption, comprising the following steps:

[0036] S1. Copper wire selection: Dissolved copper is a corrosion and dissolution reaction on the surface of metal copper. The larger the surface area of ​​the metal copper participating in the reaction, the more oxygen and solution it is exposed to. The larger the surface area of ​​the metal copper, the faster the corrosion rate per unit time. , the faster the reaction generates copper ions; the purpose of changing the φ3mm copper wire used for dissolving copper to φ1.5mm copper wire is to increase the surface area of ​​metal copper, and the surface area of ​​the same weight of metal copper when feeding is equal to increase. doubled;

Abstract

The invention belongs to the field of electrolytic copper foil production, in particular to a process for dissolving copper in electrolytic copper foil for reducing energy consumption. In the case of the existing copper dissolving production, the efficiency of dissolving copper is too low, and it is required to manually adjust the copper dissolving speed according to the current copper dissolving speed. The speed of feeding is adjusted, so that the space of the copper melter can be fully utilized, but the manual operation error is large, the operation is not timely, and the workload is large, which increases the production cost. The following scheme is now proposed, which includes the following steps: copper wire Selection: Dissolving copper is a corrosion and dissolution reaction on the surface of metal copper. The larger the surface area of ​​metal copper participating in the reaction, the more oxygen and solution it is exposed to. In the present invention, by selecting finer copper coils, the use of copper coils can be reduced The coil is placed horizontally to improve the utilization rate of air, and the amount of feed is automatically adjusted according to the current copper melting speed. While making full use of the copper melting vessel space, it can also improve the copper melting efficiency and greatly reduce the workload of workers.
