Bhawa rePremium Pure Copper Round - Kugona Kugadzira Zvinhu Zvakanaka

I. Zvishandiso uye Maitiro Ekugadzira

Zvishandiso:
Yakagadzirwa nemhangura yemagetsi yakachena kwazvo ≥99.95% (mhangura yeGiredhi 1 cathode kubva kuShanghai, Luoyang Copper, kana Jinchuan), ine tsvina yese inodzorwa pa ≤300 ppm uye huwandu hweokisijeni ≤10 ppm.

Kunyungudutsa:
Chitofu chepakati-frequency induction + chakatenderera chinoenderera mberi.
Saizi yebhiri rebhiri ≤0.12 mm, zvichibvisa kupatsanurwa, maburi, maburi ekupwanyika, nezvimwe zvikanganiso zvinowanzobatanidzwa nenzira dzechinyakare dzekukanda dzinokwira dzichienda kumusoro.

Kupisa Kunobuda:
3500T–5000T hydraulic extrusion press, chiyero cheextrusion 25–35:1, kugadzira kamwe chete.
Rutivi rwe oxide yepamusoro ≤0.03 mm, kutsungirira kwezvikamu kunodzorwa zvakadzikama mukati me ±0.10 mm.

Kudhirowa kweCold-pass yakawanda + Kubatanidza kwepakati:
Kuderedzwa kwese kwekushanda kunotonhora ≥95%.
Kunyungudutsa kunoitwa muchoto chemhando yebell-type bright annealing pasi pekuchengetedzwa kwakazara kwenitrogen mukati mekuita uku, zvichiita kuti chigadzirwa chapera chisave nekuchinja kweruvara rweoxidation uye njodzi dzekutsemuka dzinokonzereswa nekushushikana mukati.

Kupedzisa:
Kukweva-kutwasanudza kwakabatana + kuyedzwa kuviri kusingaparadze (eddy current + ultrasonic inspection).
Kuomarara kwepamusoro Ra ≤0.8 μm, kutwasuka ≤0.5 mm/m.

II. Sisitimu Yekudzora Hunhu

Kutarisira Batch Yakazara:
Kubva pa cathode copper plate → cast billet → extruded rod → finished product, physical samples dzinochengetwa padanho rega rega rekuita, pamwe chete nemishumo yekuongorora spectroscopic, mechanical, uye conductivity. Kutevedza kwakazara kunochengetwa kwemakore anopfuura mashanu.

Kugona Kuedza:
- Spektrometa yekuverenga zvakananga (kuongorora kwakazara kwezvinhu makumi maviri nematanhatu, kururama kwechinhu chimwe chete ±0.0005%)
- Kuona otomatiki eddy current + ultrasonic flaw detection (100% defects detection yakaenzana ne ≥Φ0.3 mm)
- Kuyerwa kwe conductivity otomatiki (MS/m, kururama ± 0.1% IACS)
- Muchina wekuyedza zvinhu zvepasi rose (simba rekugadzira, simba rekudhonza, kureba, kukotama kakawanda)

Magadzirirwo Ekugamuchirwa Kwefekitori Akajairika (anogona kusimbiswa zvakanyanya zvichienderana nezvinodiwa nechibvumirano):
- Kushivirira dhayamita: ± 0.10 mm (nzvimbo yeφ8–φ120 mm)
- Kufambiswa kwemagetsi: ≥58.0 MS/m (≥101% IACS)
- Kureba A: ≥40% (hasha dzakapfava)
- Saizi yetsanga: ≤0.025 mm (hasha dzakapfava)
- Pamusoro: hapana zvachose kukuvara kwemuchina, maburi, ganda reorenji, kana kuchinja ruvara rweokisijeni.
