ASTM A269 316/316L Chitsulo chosapanga dzimbiri chopindika machubu

Pamafunso ovuta omwe ali ndi zakumwa zowononga monga madzi a m'nyanja ndi mankhwala, mainjiniya nthawi zambiri amatembenukira ku ma aloyi a nickel apamwamba kwambiri monga Alloy 625 ngati chisankho chosasinthika.Rodrigo Signorelli akufotokoza chifukwa chake ma aloyi ambiri a nayitrogeni ndi njira yochepetsera chuma komanso kukana dzimbiri.

Machubu Opangidwa ndi Ma Chemical Osapanga dzimbiri

Ubwino ndi certification zimatsimikizira kusankha kwa zida zamakina monga osinthanitsa kutentha kwa mbale (PHEs), mapaipi ndi mapampu mumakampani amafuta ndi gasi.Mafotokozedwe aukadaulo amawonetsetsa kuti katundu amapereka kupitiliza kwa njira kwa moyo wautali ndikuwonetsetsa kuti zabwino, chitetezo ndi chitetezo cha chilengedwe.Ichi ndichifukwa chake ogwiritsa ntchito ambiri amaphatikiza ma aloyi a faifi tambala monga Aloyi 625 pamatchulidwe awo ndi miyezo.
Pakali pano, mainjiniya amakakamizika kuchepetsa ndalama zogulira ndalama, ndipo ma aloyi a nickel ndi okwera mtengo komanso osatetezeka kusinthasintha kwamitengo.Izi zidawonetsedwa mu Marichi 2022 pomwe mitengo ya nickel idakwera kawiri pa sabata chifukwa cha malonda amsika, ndikupanga mitu.Ngakhale mitengo yokwera imatanthawuza kuti ma aloyi a nickel ndi okwera mtengo kugwiritsa ntchito, kusakhazikika uku kumabweretsa zovuta zowongolera kwa akatswiri opanga mapangidwe chifukwa kusintha kwadzidzidzi kungakhudze phindu mwadzidzidzi.
Chotsatira chake, akatswiri ambiri opanga mapangidwe tsopano ali okonzeka kusintha Alloy 625 ndi njira zina ngakhale akudziwa kuti akhoza kudalira khalidwe lake.Chinsinsi ndicho kuzindikira alloy yoyenera ndi mlingo woyenera wa kukana kwa dzimbiri kwa machitidwe a madzi a m'nyanja ndikupereka alloy yomwe imagwirizana ndi makina.
Chinthu chimodzi choyenera ndi EN 1.4652, yomwe imadziwikanso kuti Outokumpu's Ultra 654 SMO.Imatengedwa kuti ndi chitsulo chosapanga dzimbiri chomwe sichingawonongeke kwambiri padziko lonse lapansi.
Nickel Alloy 625 imakhala ndi faifi 58%, pomwe Ultra 654 imakhala ndi 22%.Zonsezi zimakhala ndi chromium ndi molybdenum zofanana.Panthawi imodzimodziyo, Ultra 654 SMO imakhalanso ndi nayitrogeni, manganese ndi mkuwa pang'ono, 625 alloy ili ndi niobium ndi titaniyamu, ndipo mtengo wake ndi wapamwamba kwambiri kuposa faifi tambala.
Panthawi imodzimodziyo, ikuyimira kusintha kwakukulu pazitsulo zosapanga dzimbiri za 316L, zomwe nthawi zambiri zimatengedwa ngati chiyambi chazitsulo zosapanga dzimbiri.
Pankhani ya magwiridwe antchito, aloyiyo imakhala yabwino kwambiri kukana dzimbiri wamba, kukana kwambiri pakubowola ndi kugwa kwa ming'alu, komanso kukana bwino kupsinjika kwa dzimbiri.Komabe, zikafika pamakina amadzi am'nyanja, chitsulo chosapanga dzimbiri chimakhala ndi m'mphepete mwa aloyi 625 chifukwa cha kukana kwake kwa chloride.
Madzi a m'nyanja ndi owononga kwambiri chifukwa cha mchere wake wa 18,000 mpaka 30,000 pa milioni ya ayoni a kloride.Ma chloride amapereka chiwopsezo cha dzimbiri chamankhwala pamagulu ambiri azitsulo.Komabe, zamoyo zomwe zili m'madzi a m'nyanja zimatha kupanganso ma biofilms omwe amayambitsa machitidwe a electrochemical komanso kukhudza magwiridwe antchito.
Ndi nickel yake yotsika ndi molybdenum, Ultra 654 SMO alloy alloy blend imapereka ndalama zopulumutsa pamtengo wapamwamba wa 625 alloy ndikusunga magwiridwe antchito omwewo.Izi nthawi zambiri zimapulumutsa 30-40% ya mtengo.
Kuphatikiza apo, pochepetsa zomwe zili muzitsulo zamtengo wapatali, zitsulo zosapanga dzimbiri zimachepetsanso kusinthasintha kwa msika wa faifi tambala.Chotsatira chake, opanga akhoza kukhala otsimikiza kwambiri pakulondola kwa malingaliro awo apangidwe ndi zolemba zawo.
Makina azinthu ndi chinthu china chofunikira kwa mainjiniya.Mapaipi, zosinthira kutentha, ndi makina ena ayenera kupirira kupsinjika kwakukulu, kusinthasintha kwa kutentha, komanso nthawi zambiri kugwedezeka kwa makina kapena kugwedezeka.Ultra 654 SMO ili bwino m'derali.Lili ndi mphamvu zambiri zofanana ndi aloyi 625 ndipo ndipamwamba kwambiri kuposa zitsulo zina zosapanga dzimbiri.
Nthawi yomweyo, opanga amafunikira zida zowoneka bwino komanso zowotcherera zomwe zimapereka kupanga mwachangu ndipo zimapezeka mosavuta mumtundu womwe mukufuna.
Pachifukwa ichi, alloy iyi ndi chisankho chabwino chifukwa imasunga mawonekedwe abwino komanso kutalika kwabwino kwa magiredi achikhalidwe austenitic, ndikupangitsa kuti ikhale yabwino kupanga mbale zolimba, zopepuka zosinthira kutentha.
Ilinso ndi weldability wabwino ndipo imapezeka m'mitundu yosiyanasiyana kuphatikiza ma coils ndi mapepala mpaka 1000mm m'lifupi ndi 0.5 mpaka 3mm kapena 4 mpaka 6mm wandiweyani.
Phindu lina lamtengo wapatali ndiloti aloyi ili ndi kachulukidwe kakang'ono kuposa aloyi 625 (8.0 vs. 8.5 kg / dm3).Ngakhale kuti kusiyana kumeneku sikungawonekere kwakukulu, kumachepetsa matani ndi 6%, zomwe zingakupulumutseni ndalama zambiri pogula zambiri zamapulojekiti monga mapaipi a thunthu.
Pazifukwa izi, kachulukidwe kakang'ono amatanthauza kuti kapangidwe komalizidwa kamakhala kopepuka, kupangitsa kuti zikhale zosavuta kuyika, kukweza ndi kukhazikitsa.Izi ndizothandiza makamaka pamagwiritsidwe apansi panyanja ndi m'mphepete mwa nyanja pomwe machitidwe olemetsa amakhala ovuta kuthana nawo.
Poganizira mbali zonse ndi ubwino wa Ultra 654 SMO - kukana kwa dzimbiri ndi mphamvu zamakina, kukhazikika kwa mtengo ndi ndondomeko yolondola - mwachiwonekere ili ndi kuthekera kokhala njira yopikisana kwambiri ndi nickel alloys.
