Nickel strip manufacturing process method capable of reducing generation of internal bubbles

Abstract

The invention discloses a nickel strip manufacturing process method capable of reducing generation of internal bubbles, and belongs to the technical field of non-ferrous metal material processing. Thenickel strip manufacturing process method comprises the following process flows: S1, firstly, an electrolytic nickel plate which is not smelted is baked, and then cooling is conducted in an atmosphere of inert gas to obtain a pure blank; S2, the obtained pure blank is put into a smelting furnace to be smelted, and a pure nickel ingot is obtained; and S3, primary hot rolling is conducted on the obtained pure nickel ingot by using microwave rolling equipment. According to the method, through the designed microwave rolling equipment, hot rolling equipment, primary hot rolling, secondary hot rolling, warm rolling and annealing processes, on the basis that the compactness of a nickel plate can be improved and the number of micropores and bubbles in the nickel plate and on the surface of the nickel plate can be effectively controlled, a large number of bubbles can be further eliminated, the micropore number can be reduced, and new microscopic cracks and bubbles cannot be generated, so thata metal nickel strip is more compact in structure, high in rolling precision and good in effect.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal material processing, and in particular relates to a nickel strip manufacturing process method for reducing the generation of internal air bubbles. Background technique [0002] Metal nickel sheet (ie, 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, a large number of nickel strips are required. The thickness, purity and ductility of nickel strips Physical parameters such as nickel strips are the key factors affecting the quality of electronic products using them as raw materials. With the development trend of miniaturization and high performance of electronic products, more and more physical parameters such as thickness, purity and ductility of nickel strips have been proposed. Higher requirements...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the electrolytic nickel raw material plate provided by the vast majority of electrolytic nickel plate manufacturers, the production process and products are prone to defects such as delamination, peeling, and brittleness, resulting in the existence of Obvious defects such as micropores and bubbles not only weaken the process quality of the nickel strip, but also reduce the yield of the nickel strip. A nickel strip manufacturing process method that reduces the generation of internal bubbles is proposed
