Embodiment 1

[0019] A special braided copper alloy wire rod for marine enclosure fishing nets, which adopts the following technological process:

[0020] Batching—melting—casting—extrusion—stretching—annealing and pickling—drying—stretching—inspection—packing—storage

[0021] 1. Batching: it is the core technology of the present invention, the most critical process for the success of the invention. Its chemical composition is as follows:

[0022] Table 1 Chemical composition (%) of braided copper alloy wires for marine fishnets

[0023]

[0024] 2. Melting: In a power frequency induction copper melting furnace, melt the prepared charge into a qualified copper liquid (chemical composition meets the requirements in Table 1, and the temperature is 1030°C).

[0025] 3. Casting: The casting slab is pulled by a horizontal continuous casting machine, coiled to a weight of about one ton, and removed from the shelf.

[0026] 4. Extrusion: 300-type continuous extrusion machine is used to proce...

Abstract

The invention provides a special braided copper alloy wire for fishing nets for marine enclosure culture and a preparation method thereof. The wire comprises the following chemical components by mass percent: 58-75% of Cu, 0.4-1.8% of Sn, 0.2-0.5% of Si, 0.2-0.5% of Bi, not more than 0.004% of Pb, not more than 0.003% of Fe, not more than 0.0005% of Cd and the balance of Zn. The wire and the preparation method have the obvious advantages that the material is resistant to long-term seawater corrosion, is easy to braid and withstands force 25 hurricane blast; by adopting the process of replacing pulling with extruding, the blanks with high piece weights are obtained and the yield is increased; in addition, the production cycle is shortened, so that the wire is beneficial for popularization and application.

Description

technical field [0001] The invention belongs to the field of anti-corrosion metal material preparation, and in particular relates to a braided copper alloy wire material specially used for marine enclosure fishing nets and a preparation method thereof. Background technique [0002] The traditional production method of general brass wire is: use general electrolytic copper, zinc and tin to configure the alloy of "Navy Brass" series. However, the "deadly" impurity elements iron and lead will make the processed materials exceed the allowable limit required by fishing nets. Among these two impurity elements, iron is very easy to form Fe 3 0 4 And it is corroded and peeled off by seawater; lead will bring health hazards to fish and humans. Therefore, special ingredients should be used. [0003] As for the resistance to strong storms, because there are often 25 storms, there will be a strong impact on the fishing net every 7 to 12 seconds, which means that there will be about ...
