Cov yam ntxwv tseem ceeb thiab txhais ntawm E309 Vuam Qws
Stainless Hlau Vuam Erdotrode E309 (Aws E {{1} {%) yog}} {} {%), thiab molybdenum (xws li e309mol -17 Qauv) yuav muab ntxiv rau txhim kho corrosion tsis kam. Nws thawj tsim yog los daws cov teeb meem vuam ntawm stainless hlau nrog cov hlau tsis sib xws xws li vuam hlau, thiab nws yog li 304 thiab 309 series).
Raws li kev faib tawm ntawm Asmeskas Vuam Society (AWS), E309 series suav nrog ntau hom qauv ua qauv:
- E3 {{0 9}} 9l: Tsawg cov pa roj hmab tsawg dua los yog sib npaug ntawm cov kev pheej hmoo ntawm kev txhim kho ntawm thaj chaw nuclear siab.
- E3 {{0 9h: high carbon version (Carbon Cov Ntsiab Lus 0.2% {3} {}. Siv cov khoom siv cua sov thiab siv tshuaj lom neeg. E309MOL: Ntxiv Molybdenum (2% {{}}}}}%) Txhim kho cov pitting thiab yog haum rau cov marine engineering thiab petrochemical kev lag luam.
Qhov zoo thiab muaj feem cuam tshuam ntawm E309 Vuam Rods
- Thawj qhov kev xaiv rau dissimilar hlau vuam
Lub alloy muaj pes tsawg leeg ntawm E309 Vuam Rods tuaj yeem sib piv qhov sib txawv ntawm cov hlau uas muaj steel tsis muaj tseeb ntawm cov hlau uas tsis muaj zog ntawm cov hlau los ntawm kev ntxhov siab. Piv txwv li, hauv nkoj nkoj, thaum txuas rau cov hlau A36 carbon hlau thiab 304 stainless hlau thiab 304 stainless hlau thiab 304 tuaj yeem tsim lub zog mel-theem qauv, noj rau hauv tus account lub zog thiab kev sib zog.
- Zoo heev corrosion
Lub siab chromium thiab cov ntsiab lus tsib xee ua rau cov weld ua tau zoo hauv cov acidic thiab chloride ib puag ncig. Piv txwv li, cov vuam ntawm cov khoom siv ua zaub mov noj yuav tsum tau tiv thaiv organic acidority ntawm e -16 tuaj yeem zam kev txhim kho corrosion.
- Ruaj khov kev ua tau zoo
E309H VUAM RODS tseem tswj lub zog siab ntawm qhov kub siab (xws li muaj cov cua sov muaj kev lag luam), thiab haum rau cov cua sov nquag siv.
- Tus neeg teb xov tooj-phooj ywg
Cov hluav taws xob hluav taws xob muaj cov hom titanium dioxide (hom rutile), Arc yog qhov ruaj khov, thiab nws, ntsug, kab rov tav, thiab txheej txheem txheej txheem).
Cov Kev Ua Haujlwm Tshwj Xeeb thiab Kev Ceev Faj Rau E309 Electrodes
- Vuam Parameter Chaw
- Tam sim no thiab voltage: kho raws li cov hluav taws xob lub taub (piv txwv):}}}} ib (raine vuam / overhehead vuam).
- Inch 1/8 nti (3.2mm): {{{{4 4}} A (pav vuam),} ib lub vuam / remehead vuam).
- Polarity: DC Rov Qab Polarity (DCEP) lossis lwm txoj haujlwm tam sim no (AC).
- Ua ntej-vuam kev npaj
- Ntxuav cov khoom siv hauv paus: tshem tawm cov roj, xeb, thiab zam kom tsis txhob muaj thiab ua kom tawg.
- Preheating thiab txheej kub tswj: thaum vuam tuab cov hlau lossis siab carbon hlau, preheat rau} kub degree dua lossis sib npaug los tiv thaiv kev tawg ua hluav taws xob.
- Kev Kho Mob Tom Qab Weld
- Kev kho cua sov: rau cov cuab yeej siv hluav taws xob siab txhaj tshuaj, annealing yog yuav tsum tau ntawm 1038 degree -1149 optim degree kom tshem tawm cov kev ntxhov siab ntau dua thiab ua kom zoo dua cov khoom siv neeg kho tshuab.
- Pickling Passive: Siv nitric acid-hydrofluoric acid tov los ntxuav cov yeeb yaj kiab weld thiab restore cov yeeb yaj kiab oxide rau sab nraud ntawm corrosion tsis kam.
- Cia thiab Kev Tiv Thaiv
- Lub vuam pas nrig yuav tsum tau muab ntim thiab khaws cia. Tom qab qhib, nws yuav tsum tau siv lossis qhuav dua nyob rau hauv 4 teev (ziab kub {{} degree, rwb thaiv tsev rau 1 teev).
- Hnav lub npog ntsej muag thaum lub sij hawm vuam kom tsis txhob nqus roj chomium thiab npib tsib xee uas muaj pa taws.
- Kev Lag Luam Daim Ntawv Thov Kev Ua Haujlwm
- Cov khoom siv tshuaj lom neeg: E309Mol -17 yog siv rau vuam reactor) thiab cov pa roj carbon hlau, thiab cov pa roj carbon monoment rau cov sulfuric acid thiab cov organic solvent corrosion.
- Lub Zog Ua Si: E309L -16 yog siv rau cladding txheej cog kev hloov pauv ntawm lub nroog tsis muaj kev cuam tshuam cov chaw nyob thiab muaj kev nyab xeeb ntev.
- Tsheb thauj mus los: hauv cov tsheb ciav hlau ceev ceev, E309 txuas 301 Stainless hlau ncej ntawm lub tsheb lub tsheb kom tau raws li kev xav tau ntawm lub teeb yuag thiab lub zog.
Lub ntsiab
E309 series vuam rods tau dhau los ua ib qho "ntawm txhua qhov kev lag luam" hauv thaj teb ntawm stainless hlau vuam vim lawv muaj kev sib dhos thiab cov txheej txheem hloov kho tau. Los ntawm cov zaub mov Machinery rau cov khoom siv fais fab nuclear, nws cov tseem ceeb ntawm cov khoom siv dag zog hauv lub zog, corrosion tsis kam thiab ua haujlwm. Yav tom ntej, raws li qhov kev thov rau cov khoom siv sib txuas ntawm kev tsim khoom lag luam loj hlob, cov ntawv thov kev cia siab ntawm E309 thiab nws cov kev ua haujlwm ntawm E309 thiab nws cov kev ua haujlwm yuav dav. Cov neeg siv yuav tsum xaiv cov qauv raws li cov kev ua haujlwm tshwj xeeb thiab nruj me ntsis ua raws cov kev ua haujlwm kom muab kev ua si tag nrho rau lawv cov txiaj ntsig kev ua tau zoo.
