Hauv cov lag luam hnyav xws likev tsim kho dej hiav txwv, roj thiab roj av hauv hiav txwv, kev tsim kho, thiab kev thauj mus los, cov tshuab nqa thiab rigging ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb thiab kev ua tau zoo. Kev ua tiav ntawm cov cranes, hoists, winches, thiab cov khoom siv mooring feem ntau nyob ntawm ib qho tseem ceeb - lubhlua hlau.
Kev xaiv cov khoom siv zoo rau cov hlua hlau tuaj yeem txhais tau tias qhov sib txawv ntawm kev ua haujlwm ntev thiab kev saib xyuas kim lossis kev ua tsis tiav. Thaum cov hlau tsis xeb ib txwm zoo li304thiab316tau siv ntev lawm, lawv feem ntau tawm tsam hauv cov chaw muaj kev kub ntxhov nrog cov khoom thauj siab, dej ntsev, thiab cov tshuaj lom neeg corrosive.
Yog vim li ntawd ntau tus engineers thiab cov thawj coj project thiaj tig mus rau2205 Duplex Stainless Hlau xaim hlua, ib yam khoom uas sib xyaw ua kemuaj zog heev, tiv taus corrosion zoo dua, thiab ua haujlwm ntev.
Hauv tsab xov xwm no, peb yuav tshawb nrhiav vim li cas2205 Duplex Stainless Hlau xaim hluayog qhov kev xaiv ntse rau niaj hnubcov haujlwm nqa thiab rigging, nws cov yam ntxwv tshwj xeeb, cov txiaj ntsig kev ua tau zoo, thiab yuav ua li cassakysteel, ib lub tuam txhab muag khoom siv hlau tsis xeb thoob ntiaj teb, muab cov khoom Duplex uas tau ntawv pov thawj rau cov ntawv thov uas xav tau ntau yam.
Nkag Siab Txog 2205 Duplex Stainless Steel
2205 Duplex Stainless Steel (UNS S32205 / S31803)yog ib qhoob-theem hlau, muaj kwv yees li 50% austenite thiab 50% ferrite. Cov qauv microstructure no muab qhov zoo tshaj plaws ntawm ob tsev neeg stainless - lub zog ntawm ferritic hlau thiab lub zog thiab kev tiv thaiv corrosion ntawm austenitic hlau.
Cov Tshuaj Lom Zem (Ib txwm muaj):
-
Chromium (Cr):22%
-
Nickel (Ni):5–6%
-
Molybdenum (Mo): 3%
-
Nitrogen (N):0.15–0.20%
-
Hlau (Fe):Qhov Nyiaj Tshuav
Qhov kev sib xyaw ua ke ntawm cov ntsiab lus alloying no muab 2205 Duplex tshwj xeeb tiv taus raukev xeb los ntawm chloride, kev khawb av, thiabKev ntxhov siab corrosion cracking (SCC)—ua rau nws zoo tagnrho rau kev tsa thiab rigging systems uas raug dej hiav txwv, av noo, lossis cov pa tshuaj lom neeg.
Vim Li Cas Kev Xaiv Khoom Siv Tseem Ceeb Hauv Kev Nqa Thiab Rigging
Cov hlua hlau siv rau hauv kev nqa thiab rigging kav ntevkev ntxhov siab heev ntawm lub cev thiab ib puag ncigLawv yuav tsum txhawb nqa cov khoom hnyav, tiv taus kev khoov thiab torsion, thiab tiv taus xeb los ntawm cov dej noo thiab ntsev.
Cov teeb meem uas feem ntau muaj xws li:
-
Kev xeb hauv dej hiav txwv lossis tshuaj lom neeg ib puag ncig
-
Kev qaug zog ntawm cov hlauua los ntawm kev khoov rov qab
-
Kev tawg ntawm kev ntxhov siab corrosion (SCC)nyob rau hauv kev ntxhov siab
-
Kev poob zogvim yog qhov pitting thiab hnav
Yog tias cov khoom siv tsis tuaj yeem tiv taus cov yam no, nws tuaj yeem ua rau tsis ua haujlwm ua ntej lub sijhawm, muaj kev phom sij rau kev nyab xeeb, thiab lub sijhawm tsis ua haujlwm kim heev.
Qhov no yog vim li cas2205 Duplex Stainless Hlau xaim hluatau dhau los ua qhov kev daws teeb meem nyiam tshaj plaws - nws muab ob qho tib silub zog kho tshuabrau kev nqa thiabkev tiv thaiv xebrau lub neej ntev.
Cov Kev Zoo Tseem Ceeb ntawm 2205 Duplex Stainless Steel Wire Rope
1. Lub Zog Zoo Tshaj Plaws rau Cov Khoom Hnyav
Lub qauv duplex tshwj xeeb muab 2205 txoj hlua hlauyuav luag ob npaug ntawm lub zog tawm losntawm cov hlau tsis xeb 304 thiab 316, uas tso cai rau nws los tswj cov khoom thauj ntau dua nrog lub cheeb me dua.
| Vaj tse | 304 | 316 | 2205 Duplex |
|---|---|---|---|
| Lub zog Tensile (MPa) | 515 | 620 | 750–880 |

-
Cov xwm txheej acidic thiab alkaline, suav nrog sulfuric, acetic, thiab phosphoric acids.
Nrog nwsPREN (Tus lej sib npaug ntawm qhov tsis kam rau qhov poob)nyob ib puag ncig35–40, piv rau 316L's25–27, 2205 Duplex tuaj yeem nyiaj dhau qhov ntsev thiab tshuaj lom neeg uas muaj zog tshaj plaws nrog qhov tsis zoo ntawm qhov chaw.
Qhov no ua kom lub neej ua haujlwm ntev dua hauvkev tsim nkoj, cov cranes dock, thiab cov tshuab nqa khoom hauv hiav txwv.
3. Kev qaug zog thiab kev hnav tsis kam zoo heev
Kev ua haujlwm ntawm kev nqa thiab kev sib txuas cov hlua hlau yog cov yam ntxwv tseem ceebkev thauj khoom cyclic, khoov, thiab kev coCov kev ntxhov siab rov ua dua no tuaj yeem ua rau qaug zog tawg thiab hnav cov xov hlau hauv cov ntaub ntawv qib qis dua.
2205 Duplex hlau hluamuab:
-
Lub neej qaug zog zoo heevnyob rau hauv cov voj voog rov ua dua.
-
Kev tiv thaiv siab rau kev hnav thiab kev puas tsuajvim muaj zog ntxiv.
-
Cov qauv me me ruaj khovuas tiv taus qhov tawg nthuav dav.
Qhov kev tiv thaiv kev qaug zog no yog qhov tseem ceeb hauvcov winches, cov cables rub, cov hoists cawm neeg, thiab cov tshuab nqa khoom, qhov twg kev ua tau zoo sib xws hauv qab kev thauj khoom yog qhov tseem ceeb.
4. Kev Ua Tau Zoo Hauv Qhov Kub Dav Dav
Cov tshuab nqa khoom yuav tsum ua haujlwm tau zoo nyob rau hauv qhov kub thiab txias heev, txij li huab cua txias mus rau qhov av noo hauv huab cua sov.
2205 Duplex Stainless Hlau xaim hluaua tau zoo heev ntawm cov-50 ° C thiab + 300 ° C, tswj ob qho tib si tensile zog thiab yooj.
