Ibha Yesikwele Yethusi Ehlanzekile Ephezulu Ye-Premium – Ukulungele Umshini Wokukhanda Oqondile

Ukuhumusha KwesiNgisi Kobungcweti: Umzila Wenqubo Yokukhiqiza (Ukulawula Inqubo Egcwele Okuzenzakalelayo Ngokugcwele)

1. Ukukhethwa Kwezinto Ezingavuthiwe I-Premium Grade 1 cathode copper (Cu-CATH-2) etholakala ezitshalweni ze-electrolytic copper ezihamba phambili eGuizhou, eJiangxi, nakwezinye izifunda, kanye nokungcola okuphelele okulawulwa ngokuqinile ku-≤ 35 ppm.

2. Inqubo Yokuncibilikisa Ukuncibilikisa kwesithando somlilo esiphindwe kabili kusetshenziswa izitofu zokungenisa amandla-imvamisa + imvamisa ephakathi nendawo, ezivikelwe kuyo yonke indawo yi-ejenti yokumboza ehlanganisiwe yamalahle + i-graphite ehlanzekile kakhulu, futhi zivikelwe ngokuphelele ngomoya we-nitrogen/argon ukuze kuncishiswe ukuthathwa komoya-mpilo. Ukuncibilikisa okuqukethwe komoya-mpilo kulawulwa ngokuqinile ku-5–15 ppm.

3. Ukuphonsa Okuqhubekayo Okungashintshi Ukuphonsa Okuphezulu Okuqhubekayo (indlela yokudweba phezulu) nge-graphite crystallizer ehlanzekile kakhulu. Amapharamitha okudonsa alawulwa ngokunembile (isivinini sokudweba, isikhathi sokuma, kanye nesikhathi sokucindezela emuva esivumelaniswe ngokuqinile). Isisindo se-Ingot: amathani angu-1.5–2.5, okuqinisekisa isakhiwo sangaphakathi sokusanhlamvu esicwengekile futhi akukho ukuhlukaniswa okuphawulekayo.

4. Umkhuba Wokushisa Isithando somlilo esinezindawo ezintathu esiqhutshwa ngegesi, ukushisa okufanayo ku-800–850 °C, isikhathi sokubamba ≥ amahora ama-4, okuqeda ngempumelelo ukugoba okusanhlamvu kanye nokuhlukaniswa kwezakhi.

5. Ukucindezela kwe-hydraulic okushisayo okungu-3200–5000 ton, isilinganiso se-extrusion esingu-30–80, izinga lokushisa le-extrusion bar 750–800 °C, isivinini sokuphuma esingu-30–80 mm/s, okuholela ekutheni indawo ingabi nokuthungwa kwe-orange-peel kanye nesakhiwo sangaphakathi esiminyene.

6. Ukudweba/Ukulinganisa Amarola Ukudweba okubandayo okudlula izikhathi eziningi kuhlanganiswe nokunamathisela okuphakathi (580–620 °C ngaphansi komoya ovikelayo). Ukubekezelelana kobukhulu kungafinyelelwa ku-±0.10 mm, noma ku-±0.05 mm ngezidingo ezikhethekile.

7. Ukuqeda i-straightener enemigqa eyisithupha + ukugaya okungenasisekelo, kufinyelela ubulukhuni bomphezulu i-Ra ≤ 0.8 μm (i-Ra 0.4 μm iyatholakala uma ikhasimende licela).

Izinkomba Zokusebenza Zekhwalithi Eyinhloko (Isilinganiso Seqembu sika-2024–2025)

● Ubumsulwa bethusi: 99.97–99.99%
● Okuqukethwe kwe-oksijini: ≤ 10 ppm
● Ukuqhuba kukagesi: ≥ 101.5% IACS (20 °C)
● Ukwelulwa kwe-A50mm: ≥ 38%
● Usayizi wezinhlamvu: 0.015–0.035 mm (isimo sokukhipha ngemuva kokushisa)
● Ukuthambekela kokujikeleza (ukuhlolwa kokugoba okungu-1 m): ≤ 5 mm
● Ukubekezelelana kobukhulu: Okujwayelekile ± 0.15 mm; amaqoqo adwetshwe ngokunemba ± 0.08 mm
● Amaphutha ebusweni: Ayinazo izimfa, imigoqo, izinto ezifakiwe, kanye nokuthungwa kwesikhumba esinombala o-orenji
● Ukuhlolwa kwamanje kwe-Eddy: Kuhambisana ne-GB/T 5126 Class B
