Ibha Eyindilinga Yethusi Emsulwa Ephezulu – Ubuchwepheshe Bokusebenza Obuphezulu

I. Izinto Zokusetshenziswa kanye Nenqubo Yokukhiqiza

Ama-Raw material:
Kwenziwe ngethusi le-electrolytic elihlanzekile kakhulu ≥99.95% (ithusi le-cathode lebanga 1 elivela eShanghai, eLuoyang Copper, noma eJinchuan), kanti ukungcola okuphelele kulawulwa ku-≤300 ppm kanye nokuqukethwe komoya-mpilo ≤10 ppm.

Ukuncibilikisa:
Isithando sokungenisa esimaphakathi + ukuphonswa okuqhubekayo okuvundlile.
Usayizi wezinhlamvu ze-billet ≤0.12 mm, okuqeda ngempumelelo ukuhlukaniswa, ukubhoboka, imigodi yokuncibilika, kanye nezinye iziphambeko ezivame ukuhlotshaniswa nezindlela zendabuko zokuphonsa eziqhubekayo ezikhuphukayo.

Ukukhishwa Okushisayo:
Umshini wokucindezela we-hydraulic extrusion ongu-3500T–5000T, isilinganiso se-extrusion esingu-25–35:1, okwakha i-shot eyodwa.
Isendlalelo se-oxide engaphezulu ≤0.03 mm, ukubekezelelana kobukhulu kulawulwa ngokuzinzile ngaphakathi kuka-±0.10 mm.

Umdwebo Obandayo Odlula Kaningi + Ukufakwa Okuphakathi:
Ukwehla kokusebenza okubandayo okuphelele ≥95%.
Ukufakwa kwe-Annealing kwenziwa esithandweni somlilo esikhanyayo se-bell-type ngaphansi kokuvikelwa okugcwele kwe-nitrogen kuyo yonke inqubo, kuqinisekisa ukuthi umkhiqizo oqediwe awunawo umbala we-oxidation kanye nezingozi zokuqhekeka ezibangelwa ukucindezeleka kwangaphakathi.

Ukuqeda:
Ukuqondisa okuhlanganisiwe kokudweba + ukuhlolwa okubili okungabhubhisi (umshini wamanje we-eddy + ukuhlolwa kwe-ultrasonic).
Ubulukhuni bomphezulu uRa ≤0.8 μm, ukunemba ≤0.5 mm/m.

II. Uhlelo Lokulawula Ikhwalithi

Ukuphathwa Kweqoqo Lenqubo Egcwele:
Kusukela kupuleti lethusi le-cathode → i-cast billet → induku ekhishwe → umkhiqizo oqediwe, amasampula angokwenyama ayagcinwa kuzo zonke izigaba zenqubo, kanye nemibiko yokuhlola ye-spectroscopic, mechanical, kanye ne-conductivity. Ukulandelela okugcwele kugcinwa iminyaka engu-≥5.

Amakhono Okuhlola:
- I-spectrometer yokufunda ngqo (ukuhlaziywa okugcwele kwezinto ezingu-26, ukunemba kwento eyodwa ±0.0005%)
- Ukutholwa kwamanje kwe-eddy okuzenzakalelayo + amaphutha e-ultrasonic (ukutholwa kwamaphutha angu-100% okulingana no-≥Φ0.3 mm)
- Ukulinganisa ukuguquguquka okuzenzakalelayo (MS/m, ukunemba ± 0.1% IACS)
- Umshini wokuhlola izinto ojwayelekile (amandla okukhiqiza, amandla okudonsa, ukunwebeka, ukugoba okuphindaphindiwe)

Imininingwane Ejwayelekile Yokwamukelwa Kwefektri (ingaqiniswa ngokwezidingo zenkontileka):
- Ukubekezelelana kobubanzi: ± 0.10 mm (ububanzi be-φ8–φ120 mm)
- Ukuqhuba kukagesi: ≥58.0 MS/m (≥101% IACS)
- Ukwelulwa A: ≥40% (umoya ophansi)
- Usayizi wezinhlamvu: ≤0.025 mm (umoya ophansi)
- Ubuso: abunawo nhlobo umonakalo womshini, imifantu, ikhasi eliwolintshi, noma ukushintsha kombala we-oxidation.
