Hauv cov tuam txhab niaj hnub no, qhov kub kub super kub tuaj yeem muab cov ntaub ntawv tso tau rau kev sim mus kuaj. Xav txog cov khoom zoo li cov cub hluav taws xob hauv cov roj ua kom zoo, cov cav tov cov tshuab uas cua sov-} Cov ntaub ntawv kho, fais fab xwm. Cov hlau siv muaj muaj zog, tiv thaiv xeb, thiab nyob hauv ib thooj, txawm tias nws dhau 800 degree.
Tias yog vim li cas peb muaj cua sov - Tsis tshua muaj cov hlau. Lawv tau ua haujlwm kom zoo txawm tias thaum nws yog qhov kub thiab cov xwm txheej nyuaj.
1. Dab tsi yog cua sov - Tsis kam siv Stainless hlau?
Thaum tshav kub kub - Tsis kam ntawm cov hlau sib xyaw ua ke yog cov khoom siv hlau tshwj xeeb ua rau muaj kev kub ntxhov, xeb, thiab maj mam ncab thaum yam kub.
Lawv feem ntau muaj ntau cov chromium thiab npib tsib xee nyob hauv lawv. Qee zaum, lawv kuj muaj Molybdenum, titanium, lossis aluminium sib xyaw ua ke pab lawv ntev dua thiab nyob ruaj khov.
Vim tias cov kev sib xyaw no muaj zog thiab tsis xeb lossis corrode yooj yim, lawv tau txais txiaj ntsig zoo rau cua sov {{0} {kho cov khoom thiab ua kom muaj zog uas tsis nkim ntau lub zog.
2. Pom zoo cov qib kom muaj siab-} qhov kev thov kub
310s (uns tsis yog s31008)
Ib qho classic anustenitic chromium -}}}}} muaj kev tawm tsam zoo thiab tshuab ruaj khov (2100℃(2100℃f).
Nws yog dav siv nyob rau hauv rhuab feataces, kev sib txuas, thiab kev hloov cua sov.
Cov ntsiab lus tseem ceeb:
Zoo heev - lub zog kub
Kuj mus rau thermal rog thiab indoling
Cov Firjility Zoo Thiab Veldability
253ma (tsis muaj S30815)
Cov qib siab Austenic qib nrog tsawg - lub ntiaj teb micro ... 1}}}} ineloy} alloying alloying kev pabcuam ntawm 850℃thiab 1100 degree.
Nws tau muab kev pab oxidation tsis kam thiab tswj nws lub zog txawm nyob hauv cua sov hauv cua.
Cov ntsiab lus tseem ceeb:
Superien oxidation thiab creep tsis kam
High Txhua yam muaj zog ntawm kev nce siab kub
Ntau yam nyob rau hauv cua sov hais, burner Cheebtsam, thiab cov siv cov menyuam
Alloy 800H / 800HT (UN tsis muaj N08810 / N08811)
Ib npib tsib xee - hlau {}} chromium alloy ua kom ruaj khov ntawm cov qauv hluav taws xob ruaj khov ntawm huab cua sov heev.
Nws muaj lub zog tensile thiab creep zog nyob rau hauv lub sij hawm ntev raug saum 850 degree, ua rau nws nyiam hauv refinery thiab petrochemical kev ua haujlwm.
Cov ntsiab lus tseem ceeb:
Zoo heev creep rupupture lub zog
Cov qauv txheej txheem ruaj khov khov kho
Tiv taus carburization thiab thermal poob siab
310H / 321h Stainless Hlau
Siab - Cov xim carbon version ntawm cov qib unleustenic qib, ua kom zoo rauNtev - lus muaj zog khawsthiabintergranular corrosion tsis kam.
Qhov zoo tagnrho rau boiles cov leeg, pa ncho, thiab ua kom sov li cua sov.
3. Vim li cas xaiv tshav kub-} tiv taus stainless hlau?
- Superior oxidation tsis kam - cov ntaub ntawv ruaj khov chromium oxide zaj duab xis txawm nyob rau hauv huab cua lossis kev kub ntxhov.
- Lub zog sib luag ntawm cov kub thiab txias - tiv taus muag muag thiab deformation saum 800 degree.
- Microstrationation ruaj khov - tswj cov noob qoob loo ncaj raws li cua sov.
- Tus txij nkawm qis dua - txo qis qis vim kev tawg lossis ua kom sov.
4. Cov ntawv thov tseem ceeb
Thaum tshav kub kub - Tsis tshua muaj cov hlau tiv thaiv? Nws yog qhov txhia chaw: muaj cov chaw ua hluav taws xob thiab cov khoom siv cua sov. Tsis tas li ntawd, cov hwj huam hluav taws xob siv nws los tsim cov rwj thiab tso pa tawm. Nws kuj tseem tuaj yeem pom hauv Caas li kib, cov cuab yeej siv hlau, nrog rau cov cua nab kuab thiab cov roj cua sov.
Fundamentally, cov chaw no muaj cov chaw hnyav uas muaj qhov hnyav heev uas muaj kub heev, oxidation, kev ntxhov siab, thiab xeb. Zoo tib yam stainless hlau tsuas tsis tuaj yeem tiv thaiv lawv - tiag} tiag cov siab kub!
5. Xaus
Xaiv cov khoom raug rau cov mob hnyav tsis tsuas yog nws kav ntev li cas; Nws kuj tseem hais txog tej yam ua haujlwm tau zoo, thiab muaj kev nyab xeeb.
Hom nyiam 310s, 253mA, thiab Alloy 800H yog qhov zoo vim tias lawv ua haujlwm txawm tias nws dhau 800 degree. Qhov no ua rau koj muaj kev ruaj khov zoo ib yam thaum muaj tej yam tiag tiag.
Yog tias koj yog tus engineer lossis tsim khoom, khaws cov hlau tsis muaj peev xwm nqa tau tshav kub zoo li tau txais kev thaj yeeb ntawm lub siab thaum tshav kub.
