Ibha yeCopper Round ecocekileyo yePremium – Ubuchule obuphezulu bokusebenza

I. Izinto ezisetyenziswa gwenxa kunye neNkqubo yoMveliso

Iimpahla ezingekasilwa:
Yenziwe nge-electrolytic copper ecocekileyo kakhulu ≥99.95% (i-cathode copper yebanga loku-1 evela eShanghai, eLuoyang Copper, okanye eJinchuan), kunye nokungcola okupheleleyo okulawulwa kwi-≤300 ppm kunye nomxholo we-oxygen ≤10 ppm.

Ukunyibilikisa:
Isithando sokufakelwa esiphakathi-frequency + ukuphoswa okuqhubekekayo okuthe tye.
Ubungakanani bengqolowa yebhilethi ≤0.12 mm, nto leyo ephelisa ngempumelelo ukwahlulwahlulwa, ukuvuleka, ukushwabana kwemingxuma, kunye nezinye iziphene ezinxulunyaniswa neendlela zemveli zokuphosa eziqhubekekayo phezulu.

Ukukhupha Okushushu:
Umatshini wokushicilela we-hydraulic extrusion press oyi-3500T–5000T, umlinganiselo we-extrusion oyi-25–35:1, obumba i-one-shot.
Umaleko we-oxide yomphezulu ≤0.03 mm, ukunyamezelana okunomlinganiselo kulawulwa ngokuzinzileyo ngaphakathi kwe-±0.10 mm.

Umzobo obandayo odlula ngeendlela ezininzi + i-Annealing ephakathi:
Ukuncipha kokusebenza okubandayo okupheleleyo ≥95%.
Ukufakwa kwe-Annealing kwenziwa kwi-bell-type bright annealing furnace phantsi kokhuseleko olupheleleyo lwe-nitrogen kuyo yonke inkqubo, kuqinisekisa ukuba imveliso egqityiweyo ayinayo i-oxidation color kunye nemingcipheko yokuqhekeka kwangaphakathi okubangelwa luxinzelelo.

Ukugqiba:
Uvavanyo oludibeneyo lokuzoba-ukulungisa + uvavanyo oluphindwe kabini olungonakalisiyo (uvavanyo lwe-eddy current + ukuhlolwa kwe-ultrasonic).
Uburhabaxa bomphezulu uRa ≤0.8 μm, ukuthe tye ≤0.5 mm/m.

II. Inkqubo yoLawulo loMgangatho

Ulawulo lweBatch olusebenza ngokupheleleyo:
Ukusuka kwi-cathode copper plate → cast billet → extruded rod → finished product, iisampuli ezibonakalayo ziyagcinwa kwinqanaba ngalinye lenkqubo, kunye neengxelo zovavanyo lwe-spectroscopic, mechanical, kunye ne-conductivity. Ukulandelela okupheleleyo kugcinwa iminyaka eyi-≥5.

Amandla ovavanyo:
- I-spectrometer yokufunda ngqo (uhlalutyo olupheleleyo lwezinto ezingama-26, ukuchaneka kwento enye ±0.0005%)
- Ukufunyanwa kwe-eddy current ngokuzenzekelayo + ukufunyanwa kweziphene ze-ultrasonic (ukufunyanwa kweziphene eziyi-100% ezilingana ne-≥Φ0.3 mm)
- Ukulinganisa ukuhanjiswa kombane ngokuzenzekelayo (MS/m, ukuchaneka ± 0.1% IACS)
- Umatshini wokuvavanya izinto oqhelekileyo (amandla okuvelisa, amandla okutsalwa, ukunwebeka, ukugoba okuphindaphindiweyo)

Iinkcukacha eziQhelekileyo zoKwamkelwa kweFektri (zinokomelezwa ngakumbi ngokweemfuno zekhontrakthi):
- Ukunyamezelana kobubanzi: ± 0.10 mm (uluhlu lwe-φ8–φ120 mm)
- Ukuqhuba kombane: ≥58.0 MS/m (≥101% IACS)
- Ubude A: ≥40% (ubushushu obuthambileyo)
- Ubungakanani beenkozo: ≤0.025 mm (ubushushu obuthambileyo)
- Umphezulu: awunamonakalo konke konke kwi-mechanical, ii-cracks, i-orenji peel, okanye i-oxidation color.
