Inconel 800 ndi Incoloy 800H onse ndi ma aloyi a nickel-iron-chromium, koma amasiyana pang'ono ndi kapangidwe kake.
Incoloy 800 ndi aloyi ya nickel-iron-chromium yomwe idapangidwira ntchito zotentha kwambiri. Ndi ya Inkoloy mndandanda wa ma superalloys ndipo imakhala ndi kukana kwa dzimbiri m'malo osiyanasiyana.
Zolemba:
Nickel: 30-35%
Chromium: 19-23%
Iron: 39.5% osachepera
Zochepa za aluminiyamu, titaniyamu, ndi kaboni
Katundu:
Kutentha kwapamwamba: Incoloy 800 imatha kupirira kutentha kwambiri mpaka 1100 ° C (2000 ° F), ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale opangira kutentha.
Kulimbana ndi corrosion: Imapereka kukana kwabwino kwa okosijeni, carburization, ndi nitridation m'malo okhala ndi kutentha kwambiri komanso mlengalenga wokhala ndi sulfure.
Mphamvu ndi ductility: Ili ndi zida zabwino zamakina, kuphatikiza kulimba kwamphamvu komanso kulimba.
Kukhazikika kwamafuta: Incoloy 800 imasungabe katundu wake ngakhale pansi pa kutentha kwa cyclic ndi kuzizira.
Weldability: Itha kuwotcherera mosavuta pogwiritsa ntchito njira zowotcherera wamba.
Mapulogalamu: Incoloy 800 imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza:
Chemical processing: Imagwiritsidwa ntchito popanga zida monga zosinthira kutentha, zotengera zotengera, ndi mapaipi omwe amanyamula mankhwala owononga.
Kupanga magetsi: Incoloy 800 imagwiritsidwa ntchito m'mafakitale opangira magetsi otenthetsera kwambiri, monga zigawo za boiler ndi ma jenereta obwezeretsa kutentha.
Kukonzekera kwa petrochemical: Ndikoyenera zida zomwe zimawonekera kutentha kwambiri komanso malo owononga m'malo opangira mafuta a petrochemical.
ng'anjo zamafakitale: Incoloy 800 imagwiritsidwa ntchito ngati zinthu zotenthetsera, machubu owala, ndi zida zina m'ng'anjo zotentha kwambiri.
Makampani apamlengalenga ndi magalimoto: Amagwiritsidwa ntchito ngati zitini zoyatsira gasi ndi zida zamoto.
Ponseponse, Incoloy 800 ndi alloy yosunthika yokhala ndi kutentha kwambiri komanso kusamva dzimbiri, ndikupangitsa kuti ikhale yoyenera pamafakitale osiyanasiyana ovuta.
Inkoloy 800H ndi mtundu wosinthidwa wa Incoloy 800, womwe wapangidwa mwapadera kuti upereke kukana kokulirapo komanso kuwongolera mphamvu zotentha kwambiri. "H" mu Incoloy 800H imayimira "kutentha kwambiri."
Mapangidwe: Mapangidwe a Inkoloy 800H ndi ofanana ndi Inkoloy 800, ndi zosintha zina kuti apititse patsogolo kutentha kwake. Zinthu zazikulu za alloy ndi:
Nickel: 30-35%
Chromium: 19-23%
Iron: 39.5% osachepera
Zochepa za aluminiyamu, titaniyamu, ndi kaboni
Aluminiyamu ndi titaniyamu zomwe zili mkati zimaletsedwa mwadala ku Incoloy 800H kulimbikitsa kupanga gawo lokhazikika lotchedwa carbide panthawi yotentha kwambiri. Gawo ili la carbide limathandizira kukulitsa kukana kwamphamvu.
Katundu:
Mphamvu zowonjezera kutentha: Inkoloy 800H ili ndi mphamvu zamakina apamwamba kuposa Inkoloy 800 pa kutentha kokwera. Imakhalabe ndi mphamvu komanso kukhulupirika kwake ngakhale itakhala nthawi yayitali kutentha kwambiri.
Kuwongolera kukana kukwawa: Kukwawa ndi chizolowezi cha zinthu kuti zisinthe pang'onopang'ono pansi pa kupsinjika kosalekeza pa kutentha kwakukulu. Inkoloy 800H imawonetsa kukana kwamphamvu kukwawa kuposa Inkoloy 800, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kuwonetseredwa kwanthawi yayitali ndi kutentha kokwera.
Kukana kwabwino kwa dzimbiri: Mofanana ndi Inkoloy 800, Inkoloy 800H imapereka kukana kwabwino kwa okosijeni, carburization, ndi nitridation m'malo owononga osiyanasiyana.
Kuwotcherera kwabwino: Inkoloy 800H imatha kuwotcherera mosavuta pogwiritsa ntchito njira zowotcherera wamba.
Mapulogalamu: Incoloy 800H imagwiritsidwa ntchito makamaka pamagwiritsidwe pomwe kukana kutentha kwambiri komanso dzimbiri ndikofunikira, monga:
Chemical ndi petrochemical processing: Ndi yoyenera kupanga zida zogwiritsira ntchito mankhwala ankhanza, mpweya wokhala ndi sulfure, komanso malo owononga kwambiri.
Kutentha kwa kutentha: Inkoloy 800H imagwiritsidwa ntchito kwambiri popanga machubu ndi zigawo zake muzosinthira kutentha chifukwa champhamvu yake yotentha komanso kukana dzimbiri.
Kupanga magetsi: Imapeza ntchito m'mafakitale amagetsi pazinthu zomwe zimakumana ndi mpweya wotentha, nthunzi, ndi malo oyaka kwambiri.
ng'anjo za mafakitale: Inkoloy 800H imagwiritsidwa ntchito m'machubu owala, ma muffles, ndi zida zina za ng'anjo zomwe zimawonekera kutentha kwambiri.
Ma turbines a gasi: Amagwiritsidwa ntchito m'magawo ena amagetsi omwe amafunikira kukana kwamphamvu kwambiri komanso kutentha kwambiri.
Ponseponse, Inkoloy 800H ndi aloyi wapamwamba kwambiri omwe amapereka mphamvu zowonjezera kutentha komanso kutsika kwamphamvu kuyerekeza ndi Incoloy 800, ndikupangitsa kuti ikhale yoyenera pamafakitale ofunikira omwe amagwira ntchito pamatenthedwe okwera.
Inkoloy 800 ndi Incoloy 800H ndi mitundu iwiri ya aloyi ya nickel-iron-chromium yofanana, yokhala ndi kusiyana pang'ono kwa mankhwala awo ndi katundu. Nazi kusiyana kwakukulu pakati pa Inkoloy 800 ndi Incoloy 800H:
Mapangidwe a Chemical:
Inkoloy 800: Ili ndi pafupifupi 32% nickel, 20% chromium, 46% iron, yokhala ndi zinthu zina zazing'ono monga mkuwa, titaniyamu, ndi aluminiyamu.
Inkoloy 800H: Ndi mtundu wosinthidwa wa Inkoloy 800, wokhala ndi mawonekedwe osiyana pang'ono. Muli pafupifupi 32% faifi tambala, 21% chromium, 46% chitsulo, pamodzi ndi kuchuluka carbon (0.05-0.10%) ndi zotayidwa (0.30-1.20%).
Katundu:
Kutentha Kwambiri Mphamvu: Zonse za Inkoloy 800 ndi Incoloy 800H zimapereka mphamvu zabwino kwambiri komanso zamakina pamatenthedwe okwera. Komabe, Inkoloy 800H ili ndi mphamvu zowonjezera kutentha kwambiri komanso kupititsa patsogolo kukana kwa inkoloy 800. Izi ndichifukwa cha kuchuluka kwa carbon ndi aluminiyamu mu Inkoloy 800H, yomwe imalimbikitsa kupanga gawo lokhazikika la carbide, kupititsa patsogolo kukana kwake kuti asawonongeke.
Kukaniza kwa Corrosion: Inkoloy 800 ndi Incoloy 800H amawonetsa milingo yofananira yakukaniza dzimbiri, kupereka kukana kwambiri kwa okosijeni, carburization, ndi nitridation m'malo owononga osiyanasiyana.
Weldability: Ma aloyi onse amatha kuwotcherera mosavuta pogwiritsa ntchito njira wamba.
Mapulogalamu: Onse a Incoloy 800 ndi Incoloy 800H ali ndi ntchito zambiri zamafakitale pomwe mphamvu zotentha kwambiri komanso kukana dzimbiri zimafunikira. Ntchito zina zodziwika bwino ndi izi:
Zosinthana kutentha ndikuyika mapaipi m'mafakitale amafuta ndi petrochemical.
Zigawo za ng'anjo monga machubu owala, ma muffles, ndi ma tray.
Zomera zopangira magetsi, kuphatikiza zida zama boilers ndi ma turbines a gasi.
ng'anjo mafakitale ndi incinerators.
Ma gridi othandizira othandizira pakupanga mafuta ndi gasi.
Ngakhale kuti Incoloy 800 ndiyoyenera kugwiritsa ntchito kutentha kwakukulu, Incoloy 800H idapangidwira malo omwe amafunikira kukana kwamphamvu kwambiri komanso mphamvu zotentha kwambiri. Kusankha pakati pawo kumadalira ntchito yeniyeni ndi katundu wofunidwa.
