Problems solved by technology

[0002] In the traditional pure nickel tube manufacturing process, when the raw materials are smelted, the original smelting technology and equipment are used to produce and manufacture pure nickel tubes, resulting in low yield, poor tube forming quality, difficult processing, low purity, and many inclusions After the pipe is formed, it is easy to be brittle due to too high strength, which seriously affects the service life of the production equipment

Abstract

The invention relates to the technical field of tubular material manufacture and particularly relates to a manufacturing technique of a pure nickel tube. The manufacturing technique of the pure nickel tube comprises the following production steps: (1) baking a nickel plate; (2) performing vacuum refining; (3) performing electroslag remelting; (4) forging; (5) performing ultrasonic flaw detection; (6) processing a round bar; (7) performing dye penetrant inspection; (8) perforating to tube blank; (9) cropping tube blank and coping; (10) performing cold rolling, deoiling and annealing; (11) performing surface treatment; (12) performing finish rolling to obtain the product; (13) annealing; (14) shaping. By adopting the technical solution, the low finished product rate of the traditional manufacture process is solved, the finished product rate is increased, the production cost is reduced, the shaped product is easy to process, the intensity and the elongation property are greatly increased, the impurities are reduced, the degree of purity is increased and the service life of the processing device is prolonged.

Description

technical field [0001] The invention relates to the technical field of pipe material manufacturing, in particular to a production process of a pure nickel pipe. Background technique [0002] In the traditional pure nickel tube manufacturing process, when the raw materials are smelted, the original smelting technology and equipment are used to produce and manufacture pure nickel tubes, resulting in low yield, poor tube forming quality, difficult processing, low purity, and many inclusions After the pipe is formed, it is easy to be brittle due to too high strength, which seriously affects the service life of the production equipment Contents of the invention [0003] The purpose of the present invention is to provide a production process for pure nickel tubes to solve the above technical problems. [0004] The technical problem solved by the present invention can adopt following technical scheme to realize: [0005] A kind of production technology of pure nickel pipe is ch...
