Kev xaiv kom zoo rau cov khoom siv ntawm High-temperature centrifugal ntxuam
Cov khoom tseem ceeb ntawm cov kiv cua kub centrifugal yog nyob ntawm qhov kub thiab txias. Cov kub sib txawv sib txawv ntawm cov khoom sib txawv, cov qauv, thiab cov kev daws teeb meem sib khi. Hauv qab no yog cov kev xaiv ncaj qha tshaj plaws rau txhua qhov kub thiab txias, thiab koj tuaj yeem xa ncaj qha rau lawv siv.
1. Qhov kub thiab txias rau 80 ℃
Cov khoom siv rau cov kiv cua kub centrifugal: Q235, Q355 (A3 steel, 16Mn)
Daim ntawv thov: dav dav cua, boiler blower G4-73, cua txias mov
Nta: Tus nqi qis, muaj zog txaus, tsis xav tau kev kho cua sov
2.80 ℃ to 200 ℃
Cov khoom siv: Q355 (16Mn), 15CrMo
Daim ntawv thov: cua kub ncig, kab kom qhuav, dav dav boiler cua ntsawj ntshab
Nta: Cov cua sov ua haujlwm zoo creep kev ua tau zoo, tsis tshua muaj deformation
3. 200 ℃ to 350 ℃
Cov khoom siv rau cov kiv cua kub centrifugal: 15CrMo, 12Cr1MoV
Daim ntawv thov: Boiler cua ntsawj ntshab Y4-73, kiln tso pa, kub-kub flue roj
Nta: Tshwj xeeb kub-resistant steel, ruaj khov-kub lub zog
4.350 ℃ to 600 ℃
Cov khoom siv rau cov kiv cua kub centrifugal: 304 (0Cr18Ni9), 321, 316L
Daim ntawv thov: Tshuaj lom neeg kub-kub tso pa roj, incinerator, cua kub kub
Nta: Stainless hlau nrog zoo heev oxidation kuj thiab corrosion kuj
5.600 ℃ to 900 ℃
Cov khoom siv: 310S (2520), GH3030 / GH3044 high-temperature alloys
Daim ntawv thov: Metallurgical furnaces, rotary kilns, high-temperature incineration devices
Nta: Ultra-siab kub oxidation kuj, tus nqi siab
2. Kev xaiv cov khoom sib txawv 'cov ntaub ntawv rau cov kiv cua kub centrifugal (tag nrho cov tshuab txuam)
Hniav: Qhov kub siab dua, qhov tsim nyog ntau dua los xaiv cov hlau tsis muaj cua sov / stainless hlau, thiab ua kom muaj zog sib npaug + kev kho cua sov
Casing: Ib yam li cov hniav kub qib, tuaj yeem qis dua ib qib
Ncej: Rau qhov kub thiab txias, 40Cr, 42CrMo, 15CrMo yuav tsum tau ua ntej
Lub thawv kabmob: Qhov kub ib txwm, Q235 txaus, cov kiv cua kub yuav tsum tau nruab nrog lub tsho dej txias
Sealing qhov chaw:
≤250 ℃: asbestos packing, fluororubber
> 250 ℃: hlau labyrinth foob, carbon nplhaib foob
3. Ntxiv kev xaiv rau corrosion ib puag ncig ntawm high-temperature centrifugal kiv cua
Acid thiab alkali-muaj flue gas: 316L> 304> carbon steel
Muaj chloride ions: nruj me ntsis txwv tsis pub 304, yuav tsum yog 316L / 2205 duplex steel
High plua plav abrasion: ntxiv hnav-resistant hauv ob sab phlu, hnav-resistant ceramics
4. Cov ntsiab lus tseem ceeb los txiav txim siab rau kev xaiv cov kiv cua centrifugal siab
Qhov kub thiab txias> 200 ℃: yuav tsum siv lub thawv dej txias
Kub> 300 ℃: ntxiv tshav kub rwb thaiv tsev ncej tes tsho, expansion sib koom ua ke
Stainless hlau hniav: yuav tsum tau kho cov tshuaj kho kom tsis txhob deformation thiab tawg
