Embodiment 1

[0043] Such as figure 2 As shown, this embodiment includes the following steps:

[0044] a. Slitting the high-purity electrolytic nickel plate;

[0045] b. Heat the slit electrolytic nickel plate to 300°C, keep it warm for 10 hours, and perform raw material annealing treatment to fully analyze harmful substances such as hydrogen and sulfur in the electrolytic nickel plate, improve material properties, reduce brittleness, and increase toughness; resistance can be used Furnace (including well-type or horizontal inert gas atmosphere protection furnace, inert gas can use argon, nitrogen, etc., the following semi-finished products, finished annealing well-type inert gas atmosphere protection furnace is the same), or diesel combustion box-type heating furnace for annealing treatment ;

[0046] c. Rolling the pretreated electrolytic nickel plate; rolling includes repeated rolling, so that the thickness of the nickel plate is gradually rolled to the semi-finished product thickness ...

Embodiment 2

[0060] Such as figure 2 As shown, the steps of this embodiment are the same as that of Embodiment 1, the only difference is that the heating temperature is 410° C. and the temperature is kept constant for 7 hours.

Embodiment 3

[0062] Such as figure 2 As shown, the steps of this embodiment are the same as those of Embodiment 1, except that the heating temperature is 450° C. and the temperature is kept constant for 5 hours.

[0063] In the above three embodiments, the tolerance of the annealing heating temperature of the finished product is controlled within ±5° C., which can obtain a better processing effect.

Abstract

The nickel belt producing process includes rolling, annealing the semi-finished product, re-rolling, annealing the product and other steps. The said production process can ensure the high purity and low internal resistance of the nickel belt for meeting the requirement of producing battery. At the same time, the said production process is simple, low in production cost, low in power consumption, short production period and high in production efficiency.

Description

technical field [0001] The present invention relates to a kind of manufacturing method of metal nickel strip, more specifically, relates to a kind of method of directly using electrolytic nickel plate to manufacture nickel strip. Background technique [0002] Metallic nickel sheet (that is, nickel strip) is widely used in the electronic product manufacturing industry as a raw material. For example, in the production and manufacture of electronic products such as mobile phone batteries, electronic circuit boards, and light bulbs, nickel strips are widely used. Physical parameters such as thickness, purity and ductility of nickel strip are key factors affecting the quality of electronic products based on it. With the development trend of miniaturization and high performance of electronic products, higher and higher requirements are put forward for physical parameters such as thickness, purity and ductility of nickel strips, requiring thinner thickness, higher purity and better...
