Tus nyias-phab ntsa stainless hlau yeeb nkab tsim yog ua los ntawm 304 (06cr19NI10) Austenitic Stainless Hlau. Tom qab sib sau, lawv tau welded rau hauv ib qho yeeb nkab dawb, thiab tom qab ntawd txo thiab ncab rau ntau tus dhau. Tom qab cov kav dej tau ntxuav thiab qhuav, lawv muaj kev kho mob (daws teeb meem). Annealing tau muab faib ua ob txoj hauv kev: General annaling thiab ci annealing.
Nws yog hais txog qhov kev qhia tawm tsis muaj roj tiv thaiv, xws li kev txuas ntxiv txuas ntxiv hluav taws xob ua kom sov los ntawm cov nplaim taws qhib. Xws li Annealed Stainless Hlau Yeeb Nkab Fittings kuj yuav tsum tau ua pickled kom tshem tawm cov txheej txheem oxide uas tsim nyob rau saum npoo thaum lub anealing txheej txheem. Corrosion, yog li cov gloss yog neeg pluag, qhov chaw zoo li dawb, tsis kaj, thiab cov tawv tsis zoo.
Ci Plig Annealing
Muaj ob hom. Ib qho yog annealing nyob rau hauv kev tiv thaiv ntawm hydrogen tag nrho. Cov hydropen no los ntawm electrolysis lossis cov khoom siv thib peb, siab purity thiab qis lwg taw tes. Lwm tus yog decomposition nrog ammonia. Lub decomposed roj yog qhuav thiab nkag mus rau lub cub tawg. Raws li cov roj tiv thaiv, lub purity thiab lwg point yog cov tsis muaj peev xwm. Txawm li cas los xij, ob txoj hauv kev zoo sib xws nyob rau hauv uas lawv ob leeg siv hydrogen raws li cov roj tiv thaiv. Lub cub hluav taws xob ua kom sov tshwj xeeb. Muaj ib yam hu ua 'muffle ' sab hauv. Cov nplaim taws ua ntej ua kom cua sov yog 'Muffle ', thiab tom qab ntawd tshav kub hloov los ntawm tshav kub. Ua rau stainless hlau yeeb nkab fittings, yog li kom tsis txhob muaj oxidation ntawm stainless hlau yeeb nkab steel hlau fittings thiab muaj kev tiv thaiv corrosion zoo dua.
Tom qab kev ci ntsa iab ci, peb cov khoom tuaj yeem nce kev nruj ntawm cov yeeb nkab thiab tiv thaiv cov yeeb nkab los ntawm cov txheej txheem compression.
Hauv kev tsim cov nyias nyias-walled stainless hlau yeeb nkab yas, muaj teeb meem ntau lawm, uas cuam tshuam rau lub ci ci ntawm cov yeeb nkab fittings.
Yog li, dab tsi yog qhov yog dab tsi yog qhov ci ntawm nyias-walled stainless hlau annealing?
1. Kev Cuam Tshuam Ntawm Kev Tiv Thaiv
Cov Khoom Siv Ua Si Ua Si Ua Si Ua Si Ua Si Zoo Li Qub, thiab Cov Khoom Siv Hluav Taws Xob Ua Kua Dej, thiab Kua Ua Kua Ntawm Welded Yeeb Nkab Dawb Thiab du.
2. Foob ntawm lub zog cua sov
kom ntseeg tau tias cov yeeb nkab nyias uas muaj qhov sib xyaw, muab cov hluav taws xob ci, cais tawm ntawm cov huab cua sab nraud.
3.
Kev daws qhov kub ntawm qhov kub yog ib qho tseem ceeb tshaj plaws ntawm cov txheej txheem ua kua. Siab dhau los yog qis dhau yuav cuam tshuam ncaj qha rau qhov zoo ntawm cov raj xa dej. Yog tias qhov ntsuas kub siab dhau lawm, tus qauv ntawm Welded cov yeeb nkab yuav muab cov yeeb nkab welded yuav muab txo qis, thiab qhov kub yuav qis dhau. Txhawm rau tshem tawm tsis tiav, xaiv 1080 ℃ ± 10 ℃, thiab nqa tawm cov cua sov kom muaj kev txuag dej sov, kom lub carbide yuav ua tiav.
4. Kev tiv thaiv roj siab
kom tiv thaiv kom tsis txhob muaj roj me me, cov roj tiv thaiv hauv cov cua sov yuav tsum muaj qhov siab zoo. Yog tias nws yog cov pa roj pab roj av, nws feem ntau yuav tsum yog siab dua 20kbar.
5. Dej vapor nyob rau hauv lub cub tawg
ntau dhau cov cua sov cov ntsiab lus nyob rau hauv lub cub tawg thiab cuam tshuam rau annealing ci ntawm nyias-walled ci hlau yeeb nkab. Dej vapor los ntawm cov khoom siv hluav taws xob ntawm ib sab, thiab cov dej stain los ntawm cov yeeb nkab steel hlau fittings nkag rau hauv lub cub tawg rau lwm tus.
Yeej cov no yog qhov cuam tshuam uas cuam tshuam rau seb puas muaj nyias-phab ntsa stainless hlau yeeb nkab ci ntsa iab. Nyob rau hauv ib txwm muaj xwm txheej, nyias-walled-walled stainless hlau yeeb nkab uas tau ci ntsa iab yuav ci ntsa iab heev. Yog li ntawd, peb yuav tsum tsom rau cov ntsiab lus no hauv cov qauv khoom lag luam thiab cov txheej txheem ntau lawm. Raws li kev nkag siab tob ntawm cov txheej txheem ntau lawm thiab cov txheej txheem, Seco cov khoom lag luam yog tsim nrog cov ntsiab lus saum toj no hauv siab. Yog li ntawd, Hangao Tech (Seko Machinery) Ntse Ua Ntej Ua Ntej Online Ci Annealing Rauv rau Cov yeeb nkab steel hlau tshuab siv tau lees paub thiab txhawb nqa los ntawm cov neeg siv khoom tau ntau xyoo. Nws qhov zoo yog kev ntseeg siab thiab ntseeg siab.
