Cholinga cha pa intaneti yowala kutentha mankhwala a zitsulo zosapanga dzimbiri welded mapaipi: mmodzi ndi kuthetsa nkhawa yotsalira kwaiye pa ozizira ntchito ndondomeko akugubuduza zosapanga dzimbiri Mzere mu mawonekedwe tubular ndi pa ndondomeko kuwotcherera;Ndi njira yofunika kuonetsetsa ntchito ya zitsulo zosapanga dzimbiri welded mapaipi kuti olimba njira mu austenite ndiyeno mwamsanga kuziziritsa kuteteza austenite ku mphepo kapena gawo kusintha pa ndondomeko yozizira.
Zomwe Zimakhudza Chithandizo cha Kutentha Kwambiri Pa intaneti
1. Chikoka cha kutentha mankhwala kutentha
Njira yothetsera vutoli ndiyo njira yabwino kwambiri yochepetsera chitsulo chosapanga dzimbiri cha austenitic.The welded chitoliro pambuyo njira mankhwala angapeze bwino dzimbiri kukana, mphamvu m'munsi ndi pulasitiki bwino.Ndi njira iyi yokha yomwe ingakwaniritse zofunikira za mapaipi a mafakitale monga mapaipi a condenser ndi mapaipi a mankhwala.
Malinga ndi zofunikira muyezo wa mipope zosapanga dzimbiri zitsulo condensers, kutentha mankhwala kutentha austenitic zosapanga dzimbiri mipope welded ayenera kufika 1050 ~ 1150 ℃.Panthawi imodzimodziyo, pamafunikanso kuti malo amkati ndi akunja a mapaipi otsekedwa pambuyo pa kutentha kwa kutentha ndi oyera komanso osalala, opanda mtundu wa okosijeni.Choncho, pamafunika kukhala okhwima pa kutentha ndi kuziziritsa wa welded mapaipi.Kuwongolera kutentha kwamitundu yosiyanasiyana (m'ng'anjo yamoto), chitoliro chachitsulo chiyenera kukhala m'malo abwino oteteza, ndipo njira yozimitsira madzi yachikhalidwe siyingagwiritsidwe ntchito kuteteza chitoliro chachitsulo kuti chisawolere mpweya ndi oxidizing pamwamba pa chitoliro. .Kawirikawiri, njira yothetsera kutentha kwa austenitic zitsulo zosapanga dzimbiri ndi 1050 ~ 1150 ℃.Ngati kutentha uku sikunafikire, mawonekedwe amkati a chitsulo chosapanga dzimbiri cha austenitic ndi osakhazikika, ndipo carbides idzawomba, zomwe zimapangitsa kuti pamwamba pa chitoliro chachitsulo chisafike pamtundu wowala, ndipo pamwamba pa chitoliro chidzawoneka chakuda.
2. Mphamvu yoteteza gasi
The kutentha mankhwala a zitsulo zosapanga dzimbiri welded chitoliro utenga makutidwe ndi okosijeni mosalekeza kutentha mankhwala ng'anjo ndi mpweya zoteteza, amene angapeze pamwamba yowala popanda makutidwe ndi okosijeni, potero kuchotsa mwambo pickling ndondomeko.Mipweya yoteteza yomwe ingagwiritsidwe ntchito ndi hydrogen yoyera kwambiri, ammonia yowonongeka ndi mpweya wina wotetezera.Popeza chitsulo chosapanga dzimbiri welded chitoliro lili chromium, n'zosatheka kuchita kuwala kutentha mankhwala mwachizolowezi zoteteza mpweya (monga hydrocarbon mpweya kuwola, etc.), ndipo ndi bwino kuchita izo mu vacuum chilengedwe.Komabe, pochizira kutentha kwa mapaipi opangidwa ndi zitsulo zosapanga dzimbiri, malo otsekemera sangathe kugwiritsidwa ntchito, ndipo gasi wa inert (monga argon) angagwiritsidwe ntchito.Ngakhale ntchito mpweya inert monga zoteteza mpweya mankhwala kutentha kwa austenitic zosapanga dzimbiri mipope welded ali ndi makhalidwe osachita nawo zimachitikira mankhwala, ntchito yosavuta, otetezeka ndi odalirika, koma alibe kuchepetsa katundu, kotero kuti zotsatira kutentha mankhwala. sangathe kukwaniritsa zofunikira zamtundu wa kutentha kwabwino.Silver grey.Kuphatikiza apo, mtengo wa gasi wa inert ndi wokwera ndipo siwoyenera kupanga zazikulu.Malinga ndi kafukufuku pa ndondomeko kutentha mankhwala ndi kusanthula ndi mayesero mobwerezabwereza pa khalidwe la zitsulo zosapanga dzimbiri welded chitoliro pambuyo kuwala kutentha mankhwala, njira yoyamba ntchito mpweya inert kuyeretsa mpweya mu ng'anjo kutentha mankhwala, ndiyeno m'malo mpweya wa inert ndi haidrojeni, watsimikizira kuti chithandizo cha kutentha kowala chakwaniritsidwa.Zofunikira zamtundu. Hangao Tech (SEKO Machinery) Kuteteza kutentha kowala makina ochizira kutentha ndi chida chamtundu wapaintaneti, chopangidwira mizere yopangira chitoliro chosapanga dzimbiri.
3. Chikoka cha kutentha kozizira
Mukatenthetsa chitoliro chosapanga dzimbiri chosapanga dzimbiri mpaka 1050 ~ 1150 ℃, chitoliro chowotchereracho chiyenera kukhazikika mwachangu.ziyenera kutsitsidwa ku kutentha komwe sikumatulutsa okosijeni.Choncho, kutentha kozizira n'kofunika kwambiri, ndipo kutentha kumayenera kuyendetsedwa bwino.

4. Mphamvu ya welded chitoliro pamwamba
Mkhalidwe wa pamwamba pa zitsulo zosapanga dzimbiri welded chitoliro asanalowe m'ng'anjo ali ndi chikoka chachikulu pa kutentha kutentha mankhwala.Ngati pamwamba pa welded chitoliro zaipitsidwa ndi chinyezi, mafuta ndi dothi zina mu ng'anjo, kuwala wobiriwira okusayidi mtundu adzaoneka pamwamba pa welded chitoliro pambuyo yowala kutentha kutentha.Choncho, musanalowe mu ng'anjo yochizira kutentha, pamwamba pa chitoliro chosapanga dzimbiri chopangidwa ndi chitsulo chosapanga dzimbiri chiyenera kukhala choyera kwambiri, ndipo pamwamba pa chitoliro chosungunuka sayenera kuloledwa kukhala ndi chinyezi.Ngati ndi kotheka, zikhoza kuumitsidwa mu chowumitsira choyamba, ndiyeno kuika mu ng'anjo.
5. Chikoka cha Kutentha Chithandizo Chosindikizira Ng'anjo
Ng'anjo yochizira kutentha iyenera kutsekedwa ndi kupatulidwa ndi mpweya wakunja.Makamaka malo omwe chitoliro chowotcherera chimalowa m'ng'anjo ya ng'anjo ndi malo omwe chitoliro chotsekemera chimatuluka mu ng'anjo yamoto, mphete yosindikizira m'malo awa imakhala yosavuta kuvala, choncho iyenera kufufuzidwa kawirikawiri ndikusinthidwa nthawi.Pofuna kupewa kutayikira yaying'ono, mpweya woteteza m'ng'anjo uyenera kukhala ndi mphamvu zina zabwino.Ngati ndi mpweya woteteza haidrojeni, nthawi zambiri umayenera kukhala wokulirapo kuposa mphamvu ya mumlengalenga.
6. Mphamvu ya zinthu zina pa chithandizo cha kutentha kowala
Panthawi yogwira ntchito, ndikofunikira kuonetsetsa kuti kuwotcherera kumakhala kosalekeza komanso kokhazikika.Pamene pali mabowo kapena seams pa welded chitoliro ntchito ya ng'anjo kutentha kutentha ayenera kuyimitsidwa, apo ayi welded chitoliro akhoza kuwomberedwa mu ng'anjo.Komanso, kuwotcherera zotsatira si zabwino, ndi mpweya kapena chinyezi sprayed kuchokera kuwotcherera dzenje adzawononga mlengalenga zoteteza mu ng'anjo ndi kukhudza kuwala kwambiri kutentha zotsatira.
