Embodiment Construction

[0016] Considering the excellent cold working performance and poor hot working performance of the zinc-nickel-nickel copper strip, the small output and the existing production equipment, the long strip billets are casted horizontally, and then face milling, cold blanking, intermediate annealing, and cold finish rolling are carried out. , Annealing of finished products and cutting of finished products.

[0017] Its technological process is as follows:

[0018] Raw material acceptance---→Batching---→Melting---→Sampling analysis (adjustment composition)---→Transfer to holding furnace---→Sampling analysis (adjustment composition)---→Horizontal continuous casting--- →Coiling---→Face milling---→Cold billet rolling---→Edge trimming---→Intermediate annealing---→Cold intermediate rolling---→Intermediate annealing---→Finish rolling- --→annealing of finished product---→slitting---→quality inspection of finished product---→packing and storage.

Abstract

A packfong belt applying to the shell of piezoelectric crystal oscillator, the material of the copper alloy is prepared by adding nickel and zinc element, and the main chemical constituent is as following: Cu: 62.0 to 66.0 percent; Ni: 16.5 to 19.5 percent; Zn: residual. The workflow is: material checking and accepting - batching - melting - sampling and analyzing (adjusting constituent) - rolling in holding furnace - sampling and analyzing (adjusting constituent) - horizontal continuous casting - batching on - milling - cool cogging rolling - end shearing - intermediate annealing - cold rolling - intermediate annealing - fine rolling - end item annealing - cutting - end item quality inspection - packaging and warehouse-in. The invention settles many technical problems, such as the low tensile strength, the high dimensional tolerance and the poor surface finish quality of the present packfong belt, and it also improves the the shielding property and corrosion resistance.

Description

【Technical field】 [0001] The invention relates to a zinc-nickel-nickel material, in particular to a zinc-nickel-nickel strip for a piezoelectric crystal oscillator shell and a manufacturing method thereof. 【Background technique】 [0002] Zinc-nickel copper is a copper alloy material containing nickel and zinc. The alloy has a beautiful silvery white color and excellent material performance. Zinc cupronickel strips are commonly used in connectors, optical instruments, camera parts, clothing, silver plated substrates, etched bases, tableware, nameplates, radio dials, metal components, rivets, screws, truss wires, zippers, hollow parts and mandrels boilerplate etc. [0003] chemical composition Cu: 62.0-65.0% Ni: 13.5-16.0% Zn: Margin Mechanical behavior tensile strength ≥340MP Dimensional tolerance 0.23±0.015 surface finish ≤Ra0.4μm [0004] Because the tensile strength of the zinc-nickel-n...
