Kodi chitsulo chosapanga dzimbiri cha austenitic ndi chiyani? Kodi zigawo za austenitic zosapanga dzimbiri ndi ziti? Kodi zitsulo zosapanga dzimbiri za austenitic ndi ziti? Kodi zitsulo zosapanga dzimbiri za austenitic zimagwiritsidwa ntchito bwanji? M’nkhani ino, tiyankha mafunso amenewa mwatsatanetsatane.

Kodi chitsulo chosapanga dzimbiri cha austenitic ndi chiyani?

Ndi mtundu wapadera wa zosapanga dzimbiri aloyi zitsulo. Amadziwika ndi kuchuluka kwa chromium ndi faifi tambala. Chitsulo cha Austenitic sichikhala ndi maginito ndipo chimakhala ndi kuwotcherera komanso mawonekedwe ake.

Kodi zigawo za austenitic zosapanga dzimbiri ndi ziti?

Ndi aloyi ya chromium-nickel yomwe ili ndi pafupifupi 18% chromium ndi 8% nickel. Sali maginito ndipo ali ndi kukana kwa dzimbiri kuposa ena mitundu yazitsulo zosapanga dzimbiri. Chitsulo chosapanga dzimbiri cha Austenitic chimakhalanso chocheperako pakutentha kotsika.

Kodi zitsulo zosapanga dzimbiri za austenitic ndi ziti?

Ndi mtundu wapadera wazitsulo zosapanga dzimbiri zosapanga dzimbiri zomwe zili ndi chromium ndi faifi tambala. Poyerekeza ndi mitundu ina ya zitsulo zosapanga dzimbiri, ali ndi mpweya wochepa wa carbon, womwe umawapatsa kukana kwambiri kwa intergranular corrosion. Chitsulo cha Austenitic chimakhalanso ndi mawonekedwe abwino komanso kutsekemera.

Zina mwazofunikira ndi izi:

• Kukana kwakukulu
• High ductility ndi kulimba
• Kukhazikika kwabwino komanso kuwotcherera
• Kuchita bwino kwambiri kwa kutentha kochepa

Kodi zitsulo zosapanga dzimbiri za austenitic zimagwiritsidwa ntchito bwanji?

Ndilo chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito kwambiri. Ndi ma aloyi a chromium-nickel okhala ndi chromium kuyambira 16% mpaka 30% ndi faifi tambala mpaka 35%. Amadziwika chifukwa cha kukana kwawo kwa dzimbiri komanso makina abwino amakina.

Ntchito zina zodziwika bwino ndi izi:

• Zida zopangira chakudya
• Masinki ndi malo ogwirira ntchito
• Matanki osungiramo mankhwala
• Zotengera zokakamiza
• Zida zamlengalenga

Zambiri za ntchito austenitic zitsulo zosapanga dzimbiri:

Chi Austenitic 304 mbale yachitsulo chosapanga dzimbiri ndi zinthu zomwe zimati zimapatsa dzimbiri mwamphamvu komanso kukana dzimbiri, pulasitiki yabwino kwambiri komanso kulimba, ndipo ndizosavuta kuzilemba ndikuzipanga. Ndi kachulukidwe ka 7.93 g/cm³, 304 chitsulo chosapanga dzimbiri ndi mtundu wamba wazitsulo zosapanga dzimbiri, zomwe zimadziwikanso kuti 18/8 zitsulo zosapanga dzimbiri. Zogulitsa zake zachitsulo sizimatentha komanso zimakhala ndi makina abwino, zomwe zimawapangitsa kuti azigwiritsidwa ntchito kwambiri m'mafakitale monga mafakitale a mipando ndi zokongoletsera, chakudya ndi mankhwala.

Njira Yopangira Austenitic Stainless Steel

Kupanga kwachitsulo chosapanga dzimbiri cha austenitic ndikwabwino, makamaka kwa chromium-nickel austenitic chitsulo chosapanga dzimbiri. Zosiyanasiyana zomwe zimagwiritsidwa ntchito nthawi zambiri za mbale, chubu, mizere, waya, katundu wa bar, ndi forgings ndi castings zitha kupangidwa bwino pogwiritsa ntchito njira wamba popangira chitsulo chapadera.

Chifukwa cha kuchuluka kwa zinthu za alloy (makamaka chromium) komanso kutsika kwa kaboni, zitsulo zambiri zosapanga dzimbiri za austenitic zimapangidwa mochulukirapo pogwiritsa ntchito ng'anjo ya arc kuphatikiza argon-oxygen decarburization (AOD) kapena vacuum oxygen decarburization (VOD). Pazinthu zazing'ono zazing'ono, zosungunulira ng'anjo zopanda vacuum kapena zopanda vacuum zingagwiritsidwe ntchito, ndipo kusungunula kwa slag yamagetsi kungakhale kofunikira ngati kuli kofunikira.

Thermoplastic properties za chromium-nickel austenitic stainless steel zipangitsa kuti zikhale zosavuta kuchita ntchito zotentha monga kufota, kugudubuza, kuboola kotentha, ndi extrusion. Kutentha kutentha kwa ingot chitsulo ndi 1150-1260 ℃, ndi mapindikidwe kutentha osiyanasiyana zambiri 900-1150 ℃. Makalasi achitsulo okhala ndi mkuwa, nayitrogeni, ndi okhazikika ndi titaniyamu ndi niobium amakonda kudalira kutentha kotsika, pomwe ma chromium apamwamba ndi ma molybdenum zitsulo amakonda kudalira kutentha kwambiri. Chifukwa cha kusayenda bwino kwamafuta, nthawi yotsekera iyenera kukhala yayitali.

Pambuyo pokonza kutentha, chogwiritsira ntchito chikhoza kutsekedwa ndi mpweya. Chromium manganese austenitic chitsulo chosapanga dzimbiri chimakhala ndi chidwi champhamvu pakusweka kotentha. Pamene ingot yachitsulo imatsegulidwa, kusinthika kwakung'ono ndi maulendo angapo kumafunika, ndipo zojambulajambula ziyenera kutsekedwa ndi kuzizizira. Imatha kuchita njira zozizira zozizira monga kugudubuza kuzizira, kujambula kuzizira, ndi kupota, komanso kupanga maopaleshoni monga kupondaponda, kupindika, kupindika, ndi kupindika.

Chizoloŵezi choumitsa ntchito cha chromium-nickel austenitic chitsulo chosapanga dzimbiri ndi chofooka kuposa chachitsulo cha chromium-manganese, ndipo kuzizira kozizira pambuyo pa annealing kungathe kufika 70% mpaka 90%. Komabe, chifukwa cha kukana kwa mapindikidwe apamwamba komanso chizolowezi cholimba cha chromium manganese austenitic chitsulo chosapanga dzimbiri, kuchuluka kwa kufewetsa kwapakatikati kuyenera kuwonjezeka. Njira yochepetsera yapakatikati yochepetsetsa ndikuzizira kwamadzi pa 1050-1100 ℃.

Chitsulo chosapanga dzimbiri cha Austenitic chitha kugwiritsidwanso ntchito kupanga castings. Kuwongolera fluidity ya madzi zitsulo ndi kusintha ntchito kuponyera, ndi aloyi zikuchokera kuponya zitsulo ziyenera kusinthidwa: kuonjezera pakachitsulo okhutira, kukulitsa osiyanasiyana chromium ndi faifi tambala, ndi kuonjezera malire chapamwamba cha zinthu zonyansa sulfure okhutira. .

Zitsulo zosapanga dzimbiri za Austenitic ziyenera kuchitidwa chithandizo chamankhwala musanagwiritse ntchito kukulitsa njira yolimba ya carbides ndi ma precipitates ena muzitsulo mu austenite masanjidwewo, komanso homogenizing kapangidwe kake ndikuchotsa nkhawa, potero kuonetsetsa kuti kukana kwa dzimbiri ndi makina. Njira yoyenera yothetsera yankho ndikutentha pa 1050-1150 ℃ kenako madzi ozizira (zigawo zoonda zimathanso kuziziritsidwa ndi mpweya). The yankho kutentha kutentha zimadalira aloyi digiri ya zitsulo: otsika-molybdenum kapena otsika molybdenum zitsulo makaladi ayenera kukhala otsika (≤1100 ℃), pamene apamwamba aloyi sukulu monga 00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, etc. ayenera kukhala apamwamba (1080) -1150 ℃).

Ukadaulo wapamwamba umagwiritsidwa ntchito kwambiri popanga, monga kuchuluka kwa kuyenga kunja kwa ng'anjo komwe kumapitilira 95%, kuchuluka kwa kuponyera kosalekeza kupitilira 80%, ndi mphero zothamanga kwambiri, zolondola, komanso makina opangira mwachangu omwe akulimbikitsidwa kwambiri. Makamaka, kukhazikitsidwa kwaulamuliro wa makompyuta apakompyuta pakusungunula ndi kukonza kumatsimikizira kudalirika ndi kukhazikika kwazinthu zamtundu ndi magwiridwe antchito.
