Chitsulo chosapanga dzimbiri cha 15-5PH: magwiridwe antchito abwino kwambiri amatsogolera pakupanga zinthu zatsopano m'mafakitale

Kapangidwe ka mankhwala a chitsulo chosapanga dzimbiri cha 15-5PH kamawerengedwa mosamala, zomwe zimayika maziko a ntchito yake yabwino kwambiri:

Zinthu zazikulu zophatikizira zitsulo za 12CrNi3A zikuphatikizapo chromium (Cr) ndi nickel (Ni), ndipo kapangidwe kake ka mankhwala ndi:

Cr: Imapereka kukana bwino dzimbiri

Ni: Imawongolera magwiridwe antchito a zinthuzo komanso mphamvu yolimba ya mvula

Cu: Imakulitsa kwambiri mphamvu yolimba ya zinthuzo

Chidziwitso: Monga chinthu chokhazikika, chimaletsa dzimbiri pakati pa granular

Zipangizozi zimagwiritsa ntchito njira yoyeretsera yoyera (nthawi zambiri kusungunuka kwa vacuum), zimakhala ndi S yochepa (≤0.015%), kapangidwe kofanana, komanso kulimba komanso magwiridwe antchito owotcherera.

Chitsulo chosapanga dzimbiri cha 15-5PH chili ndi mphamvu zabwino kwambiri zamagetsi kutentha kwa chipinda:

Mphamvu yokoka ≥1035 MPa

Mphamvu yotulutsa ≥930 MPa

Kutalika ≥12%

Kuuma: 40-44 HRC pambuyo pa chithandizo cha kutentha

Makamaka, pansi pa mikhalidwe yofanana ya chithandizo cha kutentha cha H900 monga 17-4PH, kulimba kwa mphamvu ya 15-5PH kuli pafupifupi kawiri kuposa 17-4PH (15-5PH ≥40 J, 17-4PH ≥20 J), zomwe zimapangitsa kuti ikhale yoyenera kwambiri pazochitika zofunika kwambiri zomwe zimakhudzidwa ndi mphamvu ya kugunda ndi kutopa.

Chitsulo chosapanga dzimbiri cha 15-5PH chili ndi kukana dzimbiri bwino ndipo chimagwira ntchito bwino kwambiri m'malo ofooka mpaka ofooka, monga malo okhala ndi ma chloride ions, madzi abwino ndi mpweya wa acidic.

Pambuyo potenthedwa bwino, kukana dzimbiri kwa chitsulo chosapanga dzimbiri cha 15-5PH kumakhala bwino kwambiri kuposa kwa chitsulo chosapanga dzimbiri cha martensitic wamba. Chifukwa cha kapangidwe kake kofanana komanso kusadetsedwa pang'ono, kukana kwake ku dzenje ndi dzimbiri pakati pa granular kulinso bwino pang'ono kuposa kwa chitsulo chosapanga dzimbiri cha 17-4PH.

Chitsulo chosapanga dzimbiri cha 15-5PH chili ndi makhalidwe abwino kwambiri opangira ndi kuwotcherera:

(1) Kutha kuwotcherera bwino (kuchepa kwa sulfure kumawonjezera kukana kwa ming'alu ya malo owotcherera).

(2) Kusintha pang'ono pambuyo pa chithandizo cha kutentha (kukhazikika kwakukulu).

(3) Yoyenera kwambiri pazigawo zovuta za kapangidwe kake.

15-5PH ikhoza kulumikizidwa pogwiritsa ntchito njira iliyonse mu yankho lolimba, lakale kapena lopitirira muyeso. Sikofunikira kutentha musanagwiritse ntchito. Kutentha koyenera kumafunika mukamaliza kugwiritsa ntchito cholumikizira kuti zinthuzo zibwezeretsedwe bwino.

Katundu wa chitsulo chosapanga dzimbiri cha 15-5PH akhoza kusinthidwa kwambiri polimbitsa mpweya:

(1) Chithandizo cha yankho: Kuziziritsa mpweya kumachitika pafupifupi 1038°C kuti zinthuzo zifike pamalo ofanana otayidwa.

(2) Kuuma kwa mvula: Mikhalidwe yodziwika bwino youma ndi monga H900, H1025, H1075, H1150, ndi zina zotero. Kuphatikiza kwa mphamvu ndi kulimba kosiyanasiyana kungapezeke mwa kutenthetsa kutentha kosiyanasiyana (480°C mpaka 620°C).

Kusinthasintha kumeneku kwa kutentha kumalola kusintha bwino zinthu zakuthupi kuti zigwirizane ndi zosowa zinazake.

Chitsulo chosapanga dzimbiri cha 15-5PH chimagwiritsidwa ntchito kwambiri m'magawo otsatirawa chifukwa cha makhalidwe ake abwino kwambiri:

(1) Ndege: Kupanga zida za ndege, zida za injini ndi zomangira ndege zolimba kwambiri, zolimba komanso zosagwira dzimbiri.

(2) Makampani opanga mafuta ndi gasi: Oyenera kugwiritsa ntchito zida zoyeretsera mafuta, ma valve, mapampu, mapaipi ndi zotengera zopondereza mpweya m'malo owononga.

(3) Makampani opanga zida za nyukiliya: amagwiritsidwa ntchito popanga zida za nyukiliya ndi zida zina zomwe zimafuna mphamvu zambiri, kulimba kwambiri komanso kukana dzimbiri.

(4) Zipangizo zachipatala: zimagwiritsidwa ntchito popanga zida zopangira opaleshoni ndi zoyikamo chifukwa cha kukana dzimbiri bwino komanso kugwirizana bwino ndi zinthu zina.

(5) Zipangizo zamankhwala: zimagwiritsidwa ntchito popanga zipangizo monga ma reactor, zosinthira kutentha ndi matanki osungiramo zinthu zomwe zimafunika kupirira zinthu zowononga.

15-5PH ndi bwino kuposa 17-4PH ndipo ili ndi ubwino woonekeratu:

Malinga ndi zofunikira zenizeni zogwiritsira ntchito, chitsulo chosapanga dzimbiri cha 15-5PH chimakondedwa pazochitika zotsatirazi:

(1) Zigawo za kapangidwe kake zomwe zimafunikira kwambiri kuti zikhale zolimba komanso zowongoka

(2) Zigawo zoyendetsera ndege zolondola kwambiri

(3) Zigawo zofunika kwambiri za kapangidwe kake (chifukwa cha magwiridwe antchito awo abwino a mbali ndi kutentha kochepa)

(4) Zigawo zovuta zomwe zimafunika kutentha pambuyo powotcherera

Muzochitika zomwe mtengo wake ndi wofunika kwambiri, zida zonse zimafunika, ndipo mapangidwe a nkhungu amafunikira, 17-4PH akadali chisankho chabwino chifukwa cha mtengo wake wotsika komanso wothandiza.

Chitsulo chosapanga dzimbiri cha 15-5PH chakhala chisankho chabwino kwambiri pa ntchito zambiri zovuta chifukwa cha kulimba kwake kopingasa, kulimba bwino komanso kusinthasintha bwino.

Kugwiritsa ntchito bwino kwake mu ndege, mphamvu, zamankhwala ndi zina kwatsimikizira kuti ndi kodalirika komanso kogwira ntchito bwino. Pamene ukadaulo wamafakitale ukupitilira kukula, chitsulo chosapanga dzimbiri cha 15-5PH chipitilizabe kugwira ntchito yosasinthika m'magawo ofunikira kwambiri.
