Nrog lub ntiaj teb nuclear muaj peev xwm ua tau cog 35% los ntawm 2030, thov rauPrecision Zirconium Cheebtsamyog surging. Tsis zoo li cov hlau uas tsis zoo li cov hlau, zirconium tsawg thermal conductivity thiab siab tshuaj lom neeg cov kev sib tw tshuab sib tw.
Txheej txheem
1.Material npaj
ZIRLALOY-4 KHW (ø50 × 300 hli, Astm B353 Qib R60804)
Tshuaj lom neeg cov tshuaj lom piv rau VRF spectroscopy
2.Cnc tsis ntsuas
- Lub tshuab: Okuma mu-5000v 5-axis nrog Argon Plarge System
- Lub tuam txhab:
Pob zeb diamond -} coated nkag (DNMA150608) rau txoj siav
Khoom Carbide Kawg Mills nrog TialCrn Txheej Rau Milling
Cov txheej txheem txias:
- Cryogenic (-196 Degree Kua Nitrogen)
- Yam tsawg kawg nkaus yog lubrication (MQL)
- Dej nyab ib txwm muaj dej nyab
3.Quality Metrics
- Nto Roughness (RA, RZ)
- Subsurface microhardness (vickers ntawm 50μm kev sib pab)
- Alpha {{{}} rooj plaub txheej tuab (metallographic tsom))
Kev sib tham
1.critical txheej txheem tswj hwm
- Argon Shielding: Essential to prevent >400℃oxidation
- Nti Rhuav: Curled daim tawv yuav tsum yog<15mm to avoid re-welding
- Kho: Tsis - ferrous clamps tiv thaiv cov kab mob hlau tsis tiv thaiv kom tsis txhob muaj hlau
2.Txoj kev txiav txim siab 2.Conomic
- Thaum cryogenic system yuav tsum tau $ 120k + kev nqis peev, lawv txo:
- Post - tshuab tshuab etching nqi los ntawm 35%
- Cov nqi scrap los ntawm 8% rau<2%
- Hluav taws xob thaj chaw tshem tawm lub sijhawm
Cov txiaj ntsig & Kev Tshawb Xyuas
1.Surace Zoo sib piv
Nruab nrab saum npoo ua tiav raws li cov xwm txheej sib txawv
| Yam tseem ceeb | Ra (μm) | Alpha -} ntaub ntawv (μm) |
|---|---|---|
| Cryogenic | 0.32 | 2.1 |
| Mql | 0.48 | 3.8 |
| Dej nyab cua txias | 0.61 | 5.3 |
2.tool lub neej
Pob zeb diamond -} coated ntxig tau kav ntev 3.2x ntev dua carbide thaum cryogenic txias tau thov (87 vs {{feeb)
Tag
Rau nuclear -} qib zirconium:
- Cryogenic CNC Machining muab cov khoom siv zoo tshaj qub
- Pob zeb diamond - coated twj carbide carbide hauv txhua qhov kev ntsuas
- Kev siv txheej txheem yuav tsum muaj cov ntawv txheeb xyuas metallical
Kev tshawb nrhiav yav tom ntej yuav tsum tshawb ultrasonic - pab tau tig rau nyias- Phab ntsa Cheebtsam.
