Ibha yesikwere seCopper ecocekileyo yePremium - Ilungele ukuLungiselela ukuSebenza ngokuchanekileyo

Inguqulelo yesiNgesi yobungcali: Indlela yeNkqubo yeMveliso (Ulawulo olupheleleyo lweNkqubo oluzenzekelayo)

1. Ukukhethwa kwezinto eziluhlaza zePremium Grade 1 cathode copper (Cu-CATH-2) ephuma kwizityalo eziphambili ze-electrolytic copper eGuizhou, eJiangxi, nakwezinye iindawo, kunye nokungcola okupheleleyo okulawulwa ngokungqongqo kwi-≤ 35 ppm.

2. Inkqubo yokunyibilikisa Ukunyibilikisa isithando somlilo esiphindwe kabini kusetyenziswa ii-power-frequency + medium-frequency induction furnace, ezikhuselweyo kuyo yonke indawo yi-composite egubungelayo ye-charcoal + high-purity graphite, kwaye zikhuselwe ngokupheleleyo nge-nitrogen/argon atmosphere ukunciphisa i-oxygen pickup. Ukunyibilikisa umxholo we-oxygen kulawulwa ngokuzinzileyo kwi-5–15 ppm.

3. Ukuphosa Okuqhubekayo Okuncinci Ukuphosa Okuphezulu Okuqhubekayo (indlela yokutsala phezulu) nge-graphite crystallizer ecocekileyo kakhulu. Iiparamitha zokutsala zilawulwa ngokuchanekileyo (isantya sokutsala, ixesha lokumisa, kunye nexesha lokutyhala elibuyela umva elihambelanayo ngokungqongqo). Ubunzima be-Ingot: iitoni eziyi-1.5–2.5, ukuqinisekisa ulwakhiwo lwangaphakathi lwengqolowa olucociweyo kwaye akukho mahluko abalulekileyo.

4. Inkqubo yokuFudumeza Isithando somlilo esineendawo ezintathu esifudunyezwa ngegesi, esifudunyezwa ngokufanayo kwi-800–850 °C, ixesha lokubamba eliyi-≥ iiyure ezi-4, sisusa ngempumelelo ukubola okufana nokwahlulwahlulwa kwezinto.

5. I-Hot Extrusion 3200–5000 ton hydraulic press, umlinganiselo we-extrusion 30–80, ubushushu be-extrusion barrel 750–800 °C, isantya sokuphuma 30–80 mm/s, okubangela ukuba umphezulu ungabi nabume be-orenji-ixolo kunye nesakhiwo sangaphakathi esixineneyo.

6. Umzobo/Ukulinganisa iRoller Umzobo obandayo odlula ngeendlela ezininzi odityaniswe nokufakelwa kwe-medium-frequency (580–620 °C phantsi komoya okhuselayo). Ukunyamezelana kobukhulu obunokufikelelwa kwi-±0.10 mm, okanye ±0.05 mm kwiimfuno ezikhethekileyo.

7. Ukugqiba i-straightener ye-six-roll + ukugaya ngaphandle kwesiseko, ukufikelela kwi-surface roughness Ra ≤ 0.8 μm (Ra 0.4 μm iyafumaneka xa umthengi ecela).

Izalathisi Zokusebenza Eziphambili Zomgangatho (2024–2025 I-Batch Averages)
