Cov Tooj Liab Pure Round Bar Zoo Tshaj Plaws - Kev Siv Tau Zoo Tshaj Plaws

I. Cov Khoom Siv Raw thiab Cov Txheej Txheem Tsim Khoom

Cov Khoom Siv Raw:
Ua los ntawm cov tooj liab electrolytic purity siab ≥99.95% (Qib 1 cathode tooj liab los ntawm Shanghai, Luoyang Copper, lossis Jinchuan), nrog rau tag nrho cov impurities tswj ntawm ≤300 ppm thiab cov pa oxygen ≤10 ppm.

Kev ua hlau:
Nruab nrab-zaus induction cub tawg + kab rov tav txuas ntxiv casting.
Qhov loj ntawm cov nplej billet ≤0.12 hli, ua kom tshem tawm qhov sib cais, porosity, shrinkage cavities, thiab lwm yam tsis zoo uas feem ntau cuam tshuam nrog cov txheej txheem casting txuas ntxiv mus rau sab saud.

Kub Extrusion:
3500T–5000T hydraulic extrusion xovxwm, extrusion piv 25–35: 1, ib-phom tsim.
Txheej oxide nto ≤0.03 hli, qhov ntev kam rau siab tswj tau ruaj khov hauv ±0.10 hli.

Kev Kos Duab Txias Ntau Zaus + Kev Ua Kub Nruab Nrab:
Tag nrho cov kev txo qis ua haujlwm txias ≥95%.
Kev ua kom kub hnyiab ua tiav hauv lub cub tawg ci ntsa iab uas muaj kev tiv thaiv nitrogen tag nrho thoob plaws hauv cov txheej txheem, kom ntseeg tau tias cov khoom tiav lawm tsis muaj kev hloov pauv oxidation thiab kev ntxhov siab sab hauv uas ua rau muaj kev pheej hmoo ntawm kev tawg.

Kev Xaus:
Kev kos duab-ncaj ua ke + kev sim tsis ua puas ob zaug (eddy tam sim no + kev tshuaj xyuas ultrasonic).
Qhov roughness ntawm qhov chaw Ra ≤0.8 μm, qhov ncaj ≤0.5 hli/m.

II. Lub Txheej Txheem Tswj Xyuas Zoo

Kev Tswj Xyuas Tag Nrho Cov Txheej Txheem:
Txij ntawm daim hlau tooj liab cathode → cast billet → extruded rod → cov khoom tiav lawm, cov qauv lub cev raug khaws cia rau txhua theem ntawm cov txheej txheem, nrog rau cov ntawv qhia txog kev kuaj spectroscopic, mechanical, thiab conductivity. Kev taug qab tag nrho tau khaws cia rau ≥5 xyoos.

Kev Muaj Peev Xwm Kuaj:
- Cov spectrometer nyeem ncaj qha (kev tshuaj xyuas tag nrho ntawm 26 lub ntsiab lus, qhov tseeb ntawm ib lub ntsiab lus ± 0.0005%)
- Tsis siv neeg eddy tam sim no + ultrasonic qhov tsis zoo nrhiav kom tau (100% nrhiav tau ntawm cov tsis zoo sib npaug rau ≥Φ0.3 hli)
- Kev ntsuas qhov hluav taws xob tsis siv neeg (MS / m, qhov tseeb ± 0.1% IACS)
- Lub tshuab kuaj khoom siv thoob ntiaj teb (lub zog tawm los, lub zog tensile, elongation, rov ua dua bending)

Cov Qauv Txheem Txais Yuav Los Ntawm Lub Hoobkas (tuaj yeem ua kom nruj dua raws li cov kev cai ntawm daim ntawv cog lus):
- Kev kam rau txoj kab uas hla: ± 0.10 hli (φ8–φ120 hli ntau yam)
- Kev ua hluav taws xob conductivity: ≥58.0 MS/m (≥101% IACS)
- Kev ncua ntev A: ≥40% (mos mos)
- Qhov loj ntawm cov noob: ≤0.025 hli (mos mos)
- Qhov chaw: tsis muaj kev puas tsuaj rau lub cev, tawg, tawv txiv kab ntxwv, lossis oxidation discoloration.
