316L Stainless Hlau Micro- Hlau (5–50μm): Kos duab & Weaving Techniques Rau ± 5% Pore Uniformity
Jan 18, 2026| 1. Vim li cas 316L Micro-Wire Demands Precision?
A. Cov ntawv thov tseem ceeb yuav tsum tau ua kom nruj nruj
Cov lim dej kho mob: Ntshav filtration systems cia siab rau± 5% pore uniformitylos thaiv cov kab mob tsis muaj kev txwv tsis pub khiav.
Aerospace roj lim: Txawm a10% pore sib txawvtuaj yeem ua rau lub cav tsis ua haujlwm vim qhov tsis sib xws ntawm cov roj faib.
Kev ua tshuaj lom neeg: Corrosive kua xav tauzoo ib yam pore lojtiv thaiv kev hnav ntxov ntxov.
Piv txwv: Ib txoj kev tshawb fawb 2025 tau pom 316L micro-wire filters nrog<5% pore variationtxo cov nqi kho mob los ntawm40%nyob rau hauv offshore roj rigs.
B. Cov khoom sib tw
Siab ductility: 316L's 20% elongationua rau nws yooj yim rau caj dab thaum kos duab.
Ua hauj lwm hardening: Txhua qhov dhau los ntawm qhov tuag nce hardness los ntawm15–20 HV, yuav tsum tau intermediate annealing.
Deg tsis xws luag: A 0.1m 0.1 hlituaj yeem loj hlob mus rau hauv ib10 μm tawgthaum xaws.
Kev daws: Sivpob zeb diamond-coated tuagthiabultrasonic tunruab nrab ntawm kev hla mus kom txo tau qhov chaw puas tsuaj.
2. Kev kos duab: Los ntawm Qws mus rau 5-50μm Hlau
A. Ntau-Stage Drawing
Cov duab ntxhib: Txo cov pas nrig txoj kab uas hla ntawm2mm mus rau 0.5mmhauv 8 pass.
Kev kos duab zoo: Ua tiav50–10μmhauv 12 kis nrog5-10% txo rau ib kis.
Ultra- kos duab zoo: Mus txog5μmsiv2-3% txo rau ib kiskom tsis txhob tawg.
Cov ntaub ntawv: Ib qho kev sim 2024 tau pom99.8% tawmthaum kos 316L rau8μmsivmolybdenum tuagvs.85% yieldnrog tungsten carbide tuag.
B. Annealing ntawm theem
Kub: 1050-1100 degreerau1–3 vib nas this(luv luv dua li txheej txheem annealing los tiv thaiv kev loj hlob ntawm nplej).
Txias: Cua- txias kom zamkev tsim cov martensite, uas txo cov ductility.
Kev tshwm sim: Rov kho dua90% ntawm thawj elongationtom qab txhua kis.
Case Study: A 2026 nuclear roj lim chaw tsim khoom txo kev tawg los ntawm70%los ntawm annealing ntawm1080℃rau 2snruab nrab ntawm kev kos duab theem.
3. Cov txheej txheem rau ± 5% Pore Uniformity
A. Plain Weave vs. Dutch Weave
| Weave Hom | Pore raug | Zoo tshaj rau |
|---|---|---|
| Plain Weave | ±8–10% | Cov lim dej ntxhib (xws li kev kho dej) |
| Dutch Weave | ±3–5% | Cov ntxaij lim dej zoo (piv txwv li, tshuaj) |
Vim li cas Dutch Weave ua haujlwm zoo dua:
Tighter warp/weft ratio(eg, 1:1.5) tsimme me, ntau uniform pores.
Cov kab txaijfaib kev ntxhov siab sib npaug, txo deformation.
B. Kev Tswj Kev Nyuaj Siab Thaum Ntxov
Optimal nro: 5-8 N / mm²(siab dhau ua rau xaim elongation; tsawg dhau ua rau slack).
Tiag - saib xyuas lub sijhawm: Sivlaser micrometerskho nro dynamically.
Piv txwv: Ib qho khoom siv kho mob 2025 ua tiav± 4% pore uniformityntawm weaving ntawm6 N/mm²nrog0.5m cev.
4. Kev Tswjhwm Zoo: Yuav Ua Li Cas Txheeb Xyuas ± 5% Uniformity
A. Optical Inspection
Cov cuab yeej: Keyence VHX-7000 microscopenrog1000x magnification.
Txoj kev: Ntsuas20 random poresrau batch; tsis lees paub yog tias>1 pore tshaj ± 5%.
B. Flow Test
Teeb tsa: Pump0.1 MPa dejntawm a10 cm² lim.
Dhau cov txheej txheem: Tus nqi ntws yuav tsum nyob hauv±5%ntawm lub hauv paus.
Case Study: A 2026 aerospace tsum tsis lees paub15% ntawm batchmus txog thaum hloov mus raukev ntsuam xyuas ntws, txo qhov tsis xws luag rau<2%.
