Mpiringidzo Wozungulira Wopanda Mkuwa Wapamwamba - Kugwira Ntchito Kwambiri

I. Zipangizo ndi Njira Yopangira

Zida zogwiritsira ntchito:
Yopangidwa ndi mkuwa wa electrolytic woyeretsedwa kwambiri ≥99.95% (mkuwa wa cathode wa Giredi 1 wochokera ku Shanghai, Luoyang Copper, kapena Jinchuan), ndipo zonyansa zonse zimawongoleredwa pa ≤300 ppm ndi kuchuluka kwa mpweya ≤10 ppm.

Kusungunula:
Ng'anjo yopangira mafupipafupi apakati + kuponyera kosalekeza kopingasa.
Kukula kwa tirigu wa billet ≤0.12 mm, kuthetsa bwino kugawanika, kutseguka kwa ma pores, kufupika kwa maenje, ndi zolakwika zina zomwe zimagwirizanitsidwa ndi njira zachikhalidwe zoponyera zopitilira muyeso.

Kutentha Kwambiri:
Makina osindikizira a hydraulic extrusion a 3500T–5000T, chiŵerengero cha extrusion cha 25–35:1, kupanga kamodzi kokha.
Malo ozungulira oxide ≤0.03 mm, kulekerera kwa miyeso yokhazikika kumayendetsedwa mkati mwa ±0.10 mm.

Chojambula Chozizira Chodutsa Zambiri + Kuphimba Kwapakati:
Kuchepetsa konse kwa ntchito yozizira ≥95%.
Kuphimba zinthu kumachitidwa mu uvuni wowala wa belu pansi pa chitetezo cha nayitrogeni nthawi yonse ya ndondomekoyi, kuonetsetsa kuti chinthu chomalizidwacho chilibe kusintha kwa mtundu wa okosijeni komanso zoopsa zomwe zingachitike chifukwa cha kupsinjika kwa mkati.

Kumaliza:
Kuwongolera zojambula pamodzi + kuyesa kawiri kosawononga (eddy current + ultrasound inspection).
Kukhwima kwa pamwamba Ra ≤0.8 μm, kulunjika ≤0.5 mm/m.

II. Njira Yowongolera Ubwino

Kuyang'anira Gulu Lonse Motsatira Ndondomeko Zonse:
Kuchokera ku cathode copper plate → cast billet → extruded rod → finished product, zitsanzo zakuthupi zimasungidwa pagawo lililonse la ndondomekoyi, pamodzi ndi malipoti oyesera a spectroscopic, mechanical, ndi conductivity. Kutsata kwathunthu kumasungidwa kwa zaka ≥5.

Kuyesa Mphamvu:
- Spektromita yowerengera mwachindunji (kusanthula kwathunthu kwa zinthu 26, kulondola kwa chinthu chimodzi ±0.0005%)
- Kuzindikira kwa eddy current yokha + kuzindikira zolakwika za ultrasound (kuzindikira zolakwika 100% zofanana ndi ≥Φ0.3 mm)
- Kuyeza kwa ma conductivity okha (MS/m, kulondola ± 0.1% IACS)
- Makina oyesera zinthu zonse (mphamvu yopezera mphamvu, mphamvu yokoka, kutalika, kupindika mobwerezabwereza)

Mafotokozedwe Ovomerezeka a Fakitale (akhoza kuwonjezeredwa motsatira zomwe mgwirizano ukufuna):
- Kulekerera kwa m'mimba mwake: ± 0.10 mm (kusiyana kwa φ8–φ120 mm)
- Kuyendetsa magetsi: ≥58.0 MS/m (≥101% IACS)
- Kutalika A: ≥40% (kufatsa)
- Kukula kwa tirigu: ≤0.025 mm (kutentha pang'ono)
- Pamwamba: palibe kuwonongeka kwa makina, ming'alu, khungu la lalanje, kapena kusintha kwa mtundu wa okosijeni.
