1. Tus cim tseem ceeb: "1.4901"
Tus lej1.4901yog aTus lej KhoomLos ntawm European txheemDIN EN 10216-5Cov. Tus txheej txheem no npog "Seamless cov hlau txiav rau lub siab lub hom phiaj- process} part 5: stainless hlau leeg."
Xws li qib steel:X7crtialnb15-2
Kev tsim qauv tsis zoo: S47200
Lub Npe:Cov hlau no feem ntau hu ua a15-2 ti stidilized ferritic steel.
2. Cov khoom siv muaj pes tsawg leeg thiab cov khoom
Cov hlau no yog aFerritic Stainless HlauTshwj xeeb yog tsim rau high - kev pab kub.
Key Alloy Ntsiab & Lawv lub luag haujlwm:
Chromium (~ 15%):Muab kev tiv thaiv zoo rau oxidation (scaling) thiab corrosion ntawm qhov kub. Qhov no yog nws thawj qhov tshwj xeeb.
Titanium (TI) & Niobium (NB):Cov no yog "stabilizing" cov ntsiab lus. Lawv tiv thaiv ib qho tshwm sim "rhiab" (qhov tsim ntawm chromium carbides uas tuaj yeem ua rau kev corrosion uas tsim nyog rau vuam thiab siab- kub siv.
Aluminium (Al):Ntxiv txhim kho oxidation tsis kam.
Cov pa roj carbon tsawg:Pab nrog weldability thiab kev ruaj khov.
Cov yam ntxwv tseem ceeb:
Zoo heev - kub lub zog:Saib xyuas cov kev siv lub zog zoo ntawm qhov kub ntawm kev kwv yees li800℃(1472 Qib F).
Oxidation zoo tshaj:Ua ib qho kev tiv thaiv, ruaj khov chromium - oxide txheej uas tiv thaiv kev ntsuas thiab degradation nyob rau hauv cov huab cua lossis kev sib xyaw ua ke.
Zoo tsis kam mus rau cov tub rog rog:Ua tau zoo nyob rau hauv ib puag ncig muaj cov leej txiv leej, xws li kev sib xyaw ua pa roj.
Tsawg thermal nthuav dav:Piv nrog ustenitic stainless hlau (zoo li 304, 321), nws muaj qis coefficient ntawm kev nthuav dav thermal, uas tuaj yeem txo cov kev ntxhov siab ntawm thermal hauv kev siv.
3. Vim li cas "seamless"?
A Seamless Yeeb Nkabyog tsim los ntawm tho ib lub nplua nuj ntawm cov hlau los tsim lub raj hollow tsis muaj welds lossis nqaws.
Cov txiaj ntsig zoo rau cov khoom siv no:
Ntau dua siab ncaj ncees:Tsis muaj weld leeg txhais tau tias yog cov qauv coj ua ke, ua kom muaj zog thiab txhim khu kev qha rau cov kev siv siab.
Zoo dua rau qhov kub siab:Tshem tawm qhov kev pheej hmoo ntawm Weld tsis ua haujlwm nyob rau hauv thermal cycling.
Zoo li phab ntsa tuab:Qhov zoo tshaj plaws rau cov ntawv thov enginessing.
4. Cov Ntawv Thov Tib Neeg
1.4901 Seamless kav yog feem ntau siv nyob rau hauv high - kub, kev xeb ib puag ncig. Cov ntawv thov raug muaj xws li:
Txoj kev tso pa hluav taws xob:Tshwj xeeb rau high -} Ua haujlwm zoo li manifolds, cov vaj tse, thiab turbocharger cov tsev uas muaj kev kub ntxhov heev.
Muaj Cov Ntuab Furnaces & Boilers:Raws li cov cua sov ua kom muaj zog, radiant tub, thiab cov leeg superheater.
Petrochemical Kev Lag Luam:Hauv kev nqus dej sov thiab kho hluav taws xob.
Lub zog tiam:Hauv cov khoom siv rau cov roj thiab thee -}} raug rho tawm haujlwm fais fab nroj tsuag.
5. Cov Qauv thiab Cov Lus Qhia Tshwj Xeeb
Thaum xaj lossis tshwj xeeb 1.4901 seamless yeeb, nws yuav raug tswj hwm los ntawm cov qauv uas txhais tau nws qhov ntev, kev ua kom muaj kev thev taus, thiab kuaj. Feem ntau cov qauv yog:
DIN EN 10216-5:Seamless cov hlau tubes rau siab lub hom phiaj - prote} part 5: stainless hlau drooj.
Cov qauv no ua kom cov yeeb nkab ua kom tau raws li nruj ua tau zoo thiab kev nyab xeeb kev nyab xeeb rau cov kab ke nias.
