Bhawa rePremium Pure Copper Square - Yakagadzirira Kugadzira Machining Zvakakodzera

Shanduro yeChirungu yehunyanzvi: Nzira yekugadzira (Kudzora Maitiro Akazara Otomatiki)

1. Mhangura yemhando yepamusoro ye cathode yemhando yepamusoro (Cu-CATH-2) inotorwa kubva kumakambani makuru emhangura muGuizhou, Jiangxi, nedzimwe nzvimbo, ine tsvina yakachengetedzwa zvakanyanya pa ≤ 35 ppm.

2. Maitiro Ekunyungudutsa Furnace inonyunguduka kaviri uchishandisa maovheni emagetsi anoputika nefrequency + medium-frequency induction, anodzivirirwa nechinhu chinofukidza chakaita sechasha + high-purity graphite, uye akachengetedzwa zvizere nenitrogen/argon atmosphere kuderedza oxygen pickup. Nyungudutsa oxygen inodzorwa zvakadzikama pa5–15 ppm.

3. Kukanda Kunoenderera Mberi Kukwira Kukanda Kunoenderera Mberi (nzira yekudhonza kumusoro) ne graphite crystallizer ine hutsanana hwakanyanya. Maparamita ekubata anodzorwa nemazvo (kumhanya kwekudhonza, nguva yekumbomira, uye nguva yekusundidzira shure inopindirana zvakanaka). Kurema kweIngot: matani 1.5–2.5, zvichiita kuti chimiro chemukati chegorosi chive chakanyatsonaka uye hapana kupatsanurwa kwakakosha.

4. Hurongwa hweKudziisa Furnace ine gasi ine zvikamu zvitatu, ichidziisa zvakafanana pa800–850 °C, ichibata nguva ≥ maawa mana, zvichibvisa zvinobudirira porosity yakakandwa uye kupatsanurwa kwezvikamu.

5. Kupisa Kunodzvanya 3200–5000 tani hydraulic press, chiyero chekuburitsa 30–80, tembiricha yekuburitsa 750–800 °C, kumhanya kwekubuda 30–80 mm/s, zvichikonzera kuti pamusoro payo pasave neganda reorenji uye mukati mayo matete.

6. Kudhirowa / Kuenzanisa neRoller Drawing inotonhorera inopfuudzwa nemhepo yakawanda pamwe chete ne medium-frequency annealing (580–620 °C pasi pemhepo inodzivirira). Kushivirira kwedimensional kunogona kusvika ±0.10 mm, kana ±0.05 mm kune zvinodiwa zvakakosha.

7. Kupedzisa kururamisa simbi ine mipumburu mitanhatu + kukuya kusina pakati, zvichiita kuti ganda rive rakakombama Ra ≤ 0.8 μm (Ra 0.4 μm inowanikwa kana mutengi akumbira).

Zviratidzo zveKushanda Kwemhando Yepamusoro (2024–2025 Batch Average)

● Kuchena kwemhangura: 99.97–99.99%
● Kuwanda kweokisijeni: ≤ 10 ppm
● Kufambiswa kwemagetsi: ≥ 101.5% IACS (20 °C)
● Kureba kweA50mm: ≥ 38%
● Saizi yetsanga: 0.015–0.035 mm (mamiriro ekunze mushure mekupisa)
● Kutenderera kwemupendero (kuyedzwa kwekutenderera kwe1 m): ≤ 5 mm
● Kushivirira kwehukuru: Standard ± 0.15 mm; mabheti akadhirowewa nemazvo ± 0.08 mm
● Zvikanganiso pamusoro: Hazvina mitswe, mapete, zvinosanganisirwa, uye magadzirirwo emaganda eorenji
● Kuedzwa kweEddy kwazvino: Kunoenderana neGB/T 5126 Class B
