Abstract

The microstructure adjustment and degassing process of the electrolytic nickel plate of the present invention includes multiple cold rolling processes, vacuum heat treatment, atmosphere protection heat treatment and other processes. Electrolytic nickel plate structure adjustment and degassing process, the process method is simple, easy to operate, can effectively ensure the purity of electrolytic nickel sheet, improve the comprehensive mechanical properties and physical properties of electrolytic nickel sheet, make electronics, batteries, electric vacuum, electric light source, etc. The cold-rolled processing of high-quality nickel strip required by the industry becomes possible, which can replace the existing production process of hot-rolled electrolytic nickel sheet, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and relates to the structure adjustment and degassing process of an electrolytic nickel plate. Background technique [0002] Metal nickel strips are widely used in electronic products as conductive and structural materials, which require good electrical conductivity and chemical stability. The quality of conductivity and chemical stability is directly related to the purity of nickel strips, that is, the impurity content in nickel strips It is directly related; in order to obtain a certain thickness of nickel strip, it is also required that the microstructure of nickel is suitable for high-strength rolling processing. Nickel strips are generally produced using electrolytic nickel as a raw material. As a smelting product, the purity of electrolytic nickel itself can reach more than 99.9%. If it is directly processed by cold rolling, its composition will not change because the proc...

Problems solved by technology

However, in the process of smelting and thermal processing, the increase of impurity elements such as C, S, P, O, Cu, Fe is often unavoidable, which reduces the purity of the original pure metal, C, S, P, O, Cu, Impurity elements such as Fe are precipitated at the grain boundaries at room temperature, thereby reducing the corrosion resistance and electrical conductivity of nickel alloys

Moreover, in the process of smelting and thermal processing, due to the adhesion and oxidative burning of the metal melt, it will also cause about 6% metal loss, high energy consumption, high labor intensity, and a large amount of CO emissions. 2 and other greenhouse gases, its resource utilization rate and production efficiency are low, and the performance of the produced nickel strip cannot meet the requirements for preparing electronic products
