Zitofu za mafakitale: Incoloy 800 imagwiritsidwa ntchito ngati zinthu zotenthetsera, machubu owala, ndi zinthu zina mu zitofu zotentha kwambiri.
Makampani opanga ndege ndi magalimoto: Amagwiritsidwa ntchito m'mafakitale monga ma cani oyaka a turbine ya gasi ndi zida zina zoyatsira moto.
Ponseponse, Incoloy 800 ndi aloyi yogwiritsidwa ntchito mosiyanasiyana yokhala ndi mphamvu zabwino kwambiri zoteteza kutentha komanso dzimbiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana ovuta.
Incoloy 800H ndi mtundu wosinthidwa wa Incoloy 800, womwe wapangidwa mwapadera kuti upereke kukana kwakukulu kwa kukwawa komanso mphamvu yabwino kwambiri kutentha. "H" mu Incoloy 800H imayimira "kutentha kwakukulu."
Kapangidwe kake: Kapangidwe kake ka Incoloy 800H ndi kofanana ndi Incoloy 800, ndi zosintha zina kuti ziwongolere mphamvu zake zotentha kwambiri. Zinthu zazikulu zosakaniza ndi izi:
Nikeli: 30-35%
Chromium: 19-23%
Chitsulo: osachepera 39.5%
Aluminiyamu, titaniyamu, ndi kaboni pang'ono
Muli aluminiyamu ndi titaniyamu mwadala mu Incoloy 800H kuti mulimbikitse kupanga gawo lokhazikika lotchedwa carbide panthawi yomwe kutentha kwakhala kwa nthawi yayitali. Gawo la carbide ili limathandiza kukonza kukana kwa kukwawa.
Katundu:
Mphamvu yowonjezereka ya kutentha kwambiri: Incoloy 800H ili ndi mphamvu zambiri zamakanika kuposa Incoloy 800 pa kutentha kwakukulu. Imasunga mphamvu zake komanso kapangidwe kake ngakhale itakhala ndi kutentha kwambiri kwa nthawi yayitali.
Kukana kwabwino kwa kukwera: Kukwera ndi chizolowezi cha chinthu chomwe chimasinthasintha pang'onopang'ono chikapanikizika nthawi zonse kutentha kwambiri. Incoloy 800H imakana bwino kukwera kuposa Incoloy 800, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito nthawi zambiri kutentha kwambiri.
Kukana dzimbiri kwabwino kwambiri: Mofanana ndi Incoloy 800, Incoloy 800H imapereka kukana kwabwino kwambiri ku okosijeni, carburization, ndi nitridation m'malo osiyanasiyana owononga.
Kutha kulumikiza bwino: Incoloy 800H ikhoza kulumikizidwa mosavuta pogwiritsa ntchito njira zachikhalidwe zolumikizirana.
Kugwiritsa Ntchito: Incoloy 800H imagwiritsidwa ntchito makamaka m'malo omwe kukana kutentha kwambiri ndi dzimbiri ndikofunikira, monga:
Kukonza mankhwala ndi petrochemical: Ndikoyenera kupanga zida zogwirira ntchito ndi mankhwala amphamvu, mpweya wokhala ndi sulfure, komanso malo otentha kwambiri owononga.
Zosinthira kutentha: Incoloy 800H imagwiritsidwa ntchito kwambiri pa machubu ndi zigawo zina mu zosinthira kutentha chifukwa cha mphamvu yake yotentha kwambiri komanso kukana dzimbiri.
Kupanga magetsi: Kumapeza ntchito m'mafakitale opangira magetsi pazinthu zomwe zimakumana ndi mpweya wotentha, nthunzi, ndi malo oyaka moto otentha kwambiri.
Zitofu za mafakitale: Incoloy 800H imagwiritsidwa ntchito m'machubu owala, ma muffle, ndi zida zina za ng'anjo zomwe zimayikidwa kutentha kwambiri.
Ma turbine a gasi: Amagwiritsidwa ntchito m'ma turbine ena a gasi omwe amafunikira kukana kugwedezeka bwino komanso mphamvu yotentha kwambiri.
Ponseponse, Incoloy 800H ndi aloyi yapamwamba yomwe imapereka mphamvu yotentha kwambiri komanso kukana kugwedezeka bwino poyerekeza ndi Incoloy 800, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale ovuta omwe amagwira ntchito kutentha kwambiri.
Incoloy 800 ndi Incoloy 800H ndi mitundu iwiri ya nickel-iron-chromium alloy yomweyi, yokhala ndi kusiyana pang'ono mu kapangidwe ka mankhwala ndi mawonekedwe awo. Nazi kusiyana kwakukulu pakati pa Incoloy 800 ndi Incoloy 800H:
Kapangidwe ka Mankhwala:
Incoloy 800: Ili ndi kapangidwe ka pafupifupi 32% nickel, 20% chromium, 46% chitsulo, ndi zinthu zina zochepa monga mkuwa, titaniyamu, ndi aluminiyamu.
Incoloy 800H: Ndi mtundu wosinthidwa wa Incoloy 800, wokhala ndi kapangidwe kosiyana pang'ono. Ili ndi pafupifupi 32% nickel, 21% chromium, 46% chitsulo, pamodzi ndi kuchuluka kwa kaboni (0.05-0.10%) ndi aluminiyamu (0.30-1.20%).
Katundu:
Mphamvu Yotentha Kwambiri: Incoloy 800 ndi Incoloy 800H zonse zimapereka mphamvu zabwino komanso mphamvu zamakanika pa kutentha kwakukulu. Komabe, Incoloy 800H ili ndi mphamvu yokwera kutentha kwambiri komanso kukana kukwera kuposa Incoloy 800. Izi zimachitika chifukwa cha kuchuluka kwa kaboni ndi aluminiyamu mu Incoloy 800H, zomwe zimapangitsa kuti pakhale gawo lokhazikika la carbide, zomwe zimapangitsa kuti isamavutike ndi kusinthasintha kwa kukwera.
Kukana Kudzimbiritsa: Incoloy 800 ndi Incoloy 800H ali ndi milingo yofanana ya kukana dzimbiri, zomwe zimapereka kukana kwabwino kwambiri ku okosijeni, carburization, ndi nitridation m'malo osiyanasiyana owononga.
Kutha kulumikiza: Ma alloy onsewa amatha kulumikizidwa mosavuta pogwiritsa ntchito njira zachikhalidwe zolumikizirana.
Kugwiritsa Ntchito: Incoloy 800 ndi Incoloy 800H zonse zili ndi ntchito zosiyanasiyana zamafakitale komwe kumafunika mphamvu yotentha komanso kukana dzimbiri. Ntchito zina zodziwika bwino ndi izi:
Zosinthira kutentha ndi mapaipi opangira zinthu m'mafakitale a mankhwala ndi petrochemical.
Zinthu zosungiramo ng'anjo monga machubu owala, ma muffle, ndi ma tray.
Malo opangira magetsi, kuphatikizapo zinthu zomwe zili mu ma boiler a nthunzi ndi ma turbine a gasi.
Zitofu za mafakitale ndi zoyatsira moto.
Chothandizira chimathandizira ma gridi ndi zida zopangira mafuta ndi gasi.
Ngakhale kuti Incoloy 800 ndi yoyenera kugwiritsidwa ntchito pa kutentha kwambiri, Incoloy 800H yapangidwira makamaka malo omwe amafunikira kukana kukwera kwambiri komanso mphamvu yapamwamba kwambiri pa kutentha kwambiri. Kusankha pakati pawo kumadalira momwe imagwiritsidwira ntchito komanso makhalidwe omwe mukufuna.
