Chogulitsachi chili ndi chitsulo champhamvu cha 20Cr2Ni4A, chodziwika bwino chifukwa cha kulimba kwake komanso mphamvu zake zolimbitsa. Ndibwino kwambiri pazinthu zolemera monga magiya ndi ma shaft omwe amapirira kupsinjika kwakukulu. Dziwani kuti mutatha kugwiritsa ntchito carburizing, muyenera kupewa kuzimitsa mwachindunji kuti muchepetse austenite yomwe yasungidwa pamwamba, ndikuwonetsetsa kuti kutentha kuli bwino. Imapezeka m'madigiri kuyambira φ2mm mpaka φ500mm kuti ikwaniritse zosowa zosiyanasiyana zolondola zogwirira ntchito.
1). Zipangizo: 20Cr2Ni4A Chitsulo Chapamwamba Kwambiri cha Alloy
2). Kukula: M'mimba mwake φ2mm - φ500mm (Miyeso yamakonda imapezeka mukapempha)
3). Chithandizo cha pamwamba: Chakuda, Chowala, Chopukutidwa, kapena malinga ndi zomwe kasitomala akufuna
4). Kulongedza: Kulongedza koyenera kuyenda panyanja (komangidwa ndi zingwe zachitsulo, kokulungidwa mu pepala losalowa madzi, kapena malinga ndi zomwe kasitomala akufuna)
Kuyambira pa zoyeserera zazing'ono zoyambirira, mpaka pamitundu yonse yazinthu zachitsulo zozungulira zomwe zilipo kuyambira φ2mm mpaka φ500mm, zochitika za 20Cr2Ni4A zakhala zikuchulukirachulukira. Zocheperako (φ2 - φ50) zimagwiritsidwa ntchito kwambiri mu magiya olondola, ma plunger a pampu yamafuta, ndi zina zotero; zokulirapo zapakati ndi zazikulu (φ50 - φ500) zimagwiritsidwa ntchito kwambiri mu magiya oyendetsera magalimoto olemera, ma transmission shaft a makina akuluakulu omanga, ndi zida zogwirira ntchito zosatha za zida zamigodi. Kapangidwe kake kabwino kwambiri kozimitsa ndi kutenthetsa kamatsimikizira kuti zigawo zazikulu za zigawo zazikulu zimathanso kukhala ndi zotsatira zabwino zolimbitsa.
1. Kulimba kwambiri: Kuchuluka kwa nickel-chromium kumapangitsa kuti zinthuzo zikhale zolimba kwambiri, ndipo pakati pa zigawo zazikulu pakhoza kukhalanso ndi mphamvu yabwino yolimbitsa.
2. Kugwirizana kwamphamvu kwambiri ndi kulimba kwambiri: Kuphatikiza mphamvu yayikulu ndi kulimba kwambiri, koyenera kunyamula katundu wokhudzana ndi kugunda m'mikhalidwe yovuta yogwirira ntchito.
3. Mfundo Zofunika Kwambiri: Pambuyo pokonza carburing, kuzimitsa mwachindunji sikoyenera. M'malo mwake, kutenthetsanso kapena kuzimitsa kwambiri kuyenera kuchitidwa kuti kuchepetse austenite yotsala pamwamba, kuonetsetsa kuti ikukhala yokhazikika komanso kuti isakhale yotopa kwambiri.
4. Mitundu yazinthu: Tikhoza kupereka chitsulo chozungulira chozizira kuyambira φ2mm mpaka φ500mm, chokwaniritsa zofunikira pakukonza molondola.
20Cr2Ni4A, ngati yapamwamba kwambiriAloyi Chitsulo Chozungulira Bar, ili ndi mphamvu zambiri, kulimba kwabwino kwambiri, komanso kulimba kwapadera. Imagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zotumizira katundu wolemera, kukhudza, komanso molondola. Ndi mitundu yosiyanasiyana ya φ2 - φ500, sikuti imangokwaniritsa zofunikira pakukonzekera kwa zigawo zazing'ono zolondola komanso kukwaniritsa zofunikira pakupanga katundu wa zigawo zazikulu.
I. Dongosolo Lotumizira Makina Olemera
Zida zogwiritsira ntchito: Magiya olemera, magiya a magiya, magiya a axle oyendetsa, ma spline shafts, ma transmission cross shafts
Kufotokozera kwa malo: Mu makina opangira migodi, makina omanga ndi magalimoto akuluakulu, zida zotumizira ziyenera kupirira mphamvu yamphamvu kwambiri komanso katundu wovuta. Pambuyo pa carburizing, gawo la pamwamba la 20Cr2Ni4A limapeza kuuma kwakukulu, pomwe pakati pake pamakhala kuuma kwakukulu, komwe kumatha kukana kuwonongeka kwa pamwamba pa dzino ndi kusweka kwa mizu ya dzino, zomwe zimapangitsa kuti ntchito ya zida izi ikhale yolimba kwambiri.
II. Zida za Ndege ndi Zankhondo
Zigawo zogwiritsira ntchito: Zigawo za shaft ya injini ya ndege, zigawo za zida zotera, zigawo za zida
Kufotokozera kwa malo: Zinthuzi zikugwirizana ndi muyezo wa GB/T 3078-2008 wa chitsulo chapamwamba kwambiri ndipo zimakhala ndi kukana kutopa kwambiri. Ndizoyenera malo oyendera ndege ndi zida zapadera komwe kudalirika kwa zinthuzo ndikofunikira kwambiri.
III. Ma Molds Olondola ndi Ma Jig Ogwiritsira Ntchito Zipangizo
Zigawo zogwiritsira ntchito: Chophimba cha mutu wozizira, chimango cholondola cha nkhungu, chogwirira champhamvu kwambiri, pini yopezera malo
Kufotokozera kwa malo: Chitsulo chozungulira chaching'ono (φ2 - φ50) 20Cr2Ni4A chimagwiritsidwa ntchito popanga zida za nkhungu zolimba komanso zosamalidwa bwino. Kukhazikika kwake kwabwino kwambiri pakusamalira kutentha kumatsimikizira kulondola kwa malo obwerezabwereza pakukonza molondola.
IV. Ntchito za Mafuta ndi Migodi
Zogwiritsira ntchito: Cholumikizira chobowola, malaya osatha, shaft yayikulu yophwanyira
Kufotokozera kwa malo: M'malo ovuta kwambiri ogwirira ntchito m'migodi ndi m'malo obowola mafuta, zida ziyenera kupirira kuwonongeka kwa mchenga ndi kupsinjika kwakukulu. Kulimba kwambiri kwa 20Cr2Ni4A kumatsimikizira kuti makinawo ali ndi mphamvu zofanana pakati pa zigawo zazikulu (zokhala ndi mainchesi a 100mm kapena kuposerapo), zomwe zimakwaniritsa zofunikira pakakhala zovuta kwambiri.
V. Kuyendera Sitima ndi Kumanga Zombo
Zigawo zogwiritsira ntchito: magiya ogwirira ntchito a locomotive, ma bogie pin shafts, zolumikizira ndodo zoyendetsera
Kufotokozera za malo: Zigawo za sitima ndi zombo nthawi zonse zimakhala ndi katundu ndi kugwedezeka kosinthasintha. Kuphatikiza kwa mphamvu ndi kulimba kwa chinthucho, pamodzi ndi mkhalidwe wopsinjika wa pamwamba pa carburing, kumatha kuchedwetsa kuyambitsa ming'alu yotopa ndikuwonetsetsa kuti ntchitoyo ndi yotetezeka.
Kugwiritsa ntchito
Monga makampani otsogola mumakampani opanga zinthu zachitsulo ku China, malonda achitsulo ndi zinthu zamtundu wa "Zana la bizinesi yabwino", makampani ogulitsa zitsulo ku China, "Mabizinesi 100 apamwamba kwambiri ku Shanghai". Shanghai Zhanzhi industry Group Co., Ltd., (yofupikitsidwa ku Zhanzhi Group) imatenga "Umphumphu, Kuchita Zinthu Mwanzeru, Kupanga Zinthu Mwatsopano, Kupambana" ngati mfundo yokhayo yogwirira ntchito, nthawi zonse imapitiliza kuyika zofuna za makasitomala pamalo oyamba.
