Mpiringidzo Wapamwamba Wa Copper Square Bar - Wokonzeka Kukonza Machining

Kumasulira Kwaukadaulo Kwa Chingerezi: Njira Yopangira (Yodzilamulira Yokha Yonse)

1. Kusankha Zinthu Zosaphika Zamtengo Wapatali wa Cathode wa Giredi 1 (Cu-CATH-2) wochokera ku zomera zotsogola zamkuwa za electrolytic ku Guizhou, Jiangxi, ndi madera ena, ndipo zodetsa zonse zimayendetsedwa mosamala pa ≤ 35 ppm.

2. Njira Yosungunula Kusungunula kwa ng'anjo ziwiri pogwiritsa ntchito mphamvu-frequency + medium-frequency induction furnace, yotetezedwa ndi chophimba cha makala + high-purity graphite, komanso yotetezedwa kwathunthu ndi mpweya wa nayitrogeni/argon kuti muchepetse kutengedwa kwa mpweya. Sungunulani kuchuluka kwa mpweya woipa mokhazikika pa 5–15 ppm.

3. Kuponya Kosalekeza Kopitirira Kukwera Kopitilira (njira yokwezera mmwamba) ndi graphite crystallizer yoyera kwambiri. Magawo ogwirira ntchito amawongoleredwa bwino (liwiro lojambula, nthawi yopuma, ndi nthawi yokankhira kumbuyo yolumikizidwa bwino). Kulemera kwa Ingot: matani 1.5–2.5, kuonetsetsa kuti kapangidwe ka tirigu wamkati ndi koyenera komanso palibe kusiyana kwakukulu.

4. Ndondomeko Yotenthetsera Uvuni wotentha wokhala ndi malo atatu wokhala ndi mpweya, kutentha kofanana pa 800–850 °C, kusunga nthawi ≥ maola 4, kuchotsa bwino ma porosity omwe amapangidwa komanso kusiyanitsa zinthu.

5. Kutulutsa Kotentha kwa 3200–5000 tani hydraulic press, chiŵerengero cha kutulutsa 30–80, kutentha kwa mbiya ya kutulutsa 750–800 °C, liwiro lotuluka 30–80 mm/s, zomwe zimapangitsa kuti pamwamba pake pasakhale mawonekedwe a lalanje komanso mkati mwake mukhale wokhuthala.

6. Kujambula / Kulinganiza kwa Roller Kujambula kozizira kopitilira muyeso wophatikizana ndi kupopera kwapakati (580–620 °C pansi pa mlengalenga woteteza). Kulekerera kwa miyeso kumatha kufika ±0.10 mm, kapena ±0.05 mm pazofunikira zapadera.

7. Kumaliza chowongolera cha mipukutu isanu ndi umodzi + chopanda pakati, chomwe chimakwaniritsa kuuma kwa pamwamba pa Ra ≤ 0.8 μm (Ra 0.4 μm imapezeka ngati kasitomala akufuna).

Zizindikiro Zofunikira za Ubwino Wabwino (2024–2025 Batch Average)

● Kuyera kwa mkuwa: 99.97–99.99%
● Kuchuluka kwa mpweya: ≤ 10 ppm
● Kuyendetsa magetsi: ≥ 101.5% IACS (20 °C)
● Kutalika kwa A50mm: ≥ 38%
● Kukula kwa tirigu: 0.015–0.035 mm (mkhalidwe wa extrusion pambuyo pa kutentha)
● Kuzungulira kwa mlengalenga (kuyesa kwa torsion ya 1 m): ≤ 5 mm
● Kulekerera kwa miyeso: Standard ± 0.15 mm; magulu okokedwa molondola ± 0.08 mm
● Zolakwika pamwamba: Zopanda ming'alu, mapindidwe, zophatikizika, komanso kapangidwe ka khungu la lalanje
● Kuyesa kwa Eddy current: Kugwirizana ndi GB/T 5126 Class B
