Kuchulukana kwa Zitsulo za 4140: Zingatenge Mphamvu Yamphamvu Motani?

Mu engineering design,perekani kupsinjikandi chimodzi mwazinthu zofunika kwambiri zamakina posankha zida zamapangidwe kapena zonyamula katundu. Imatanthawuza pomwe chinthu chimayamba kupunduka pulasitiki - kutanthauza kuti sichibwereranso ku mawonekedwe ake apachiyambi katunduyo atachotsedwa. Zikafika pazitsulo za alloy,4140 zitsulondi imodzi mwazosankha zodziwika bwino komanso zodalirika chifukwa cha mphamvu zake zokolola zambiri komanso makina abwino kwambiri.

Nkhaniyi kuchokerasakysteelzimatengera mozama kupsinjika kwa zokolola za chitsulo cha 4140, momwe zimasiyanasiyana ndi chithandizo cha kutentha, komanso chifukwa chake zimafunikira pakugwiritsa ntchito mafakitale enieni. Tidzafaniziranso ndi zitsulo zina zaumisiri wamba kuti zikuthandizeni kusankha zinthu zoyenera.

Kodi 4140 Steel ndi chiyani?

4140 chitsulo ndichromium-molybdenum aloyi chitsulozagawidwa pansi pa dongosolo la AISI-SAE. Zimaphatikiza kulimba, kutopa kwakukulu, komanso kulimba mtima kwambiri, zomwe zimapangitsa kuti zikhale zoyenera pazinthu zopanikizika kwambiri pamagalimoto, mlengalenga, mafuta ndi gasi, komanso kupanga makina.

Kapangidwe kake kamene kamaphatikizapo:

  • Mpweya: 0.38% -0.43%

  • Chromium: 0.80% - 1.10%

  • Manganese: 0.75% - 1.00%

  • Molybdenum: 0.15% - 0.25%

  • silicon: 0.15% - 0.35%

Zinthu zophatikizikazi zimagwirira ntchito limodzi kuti chitsulocho chizitha kukana mapindikidwe akapanikizika ndikukhalabe olimba kwambiri.

Kufotokozera Kupsinjika kwa Zokolola

Zokolola kupsinjika, kapenaperekani mphamvu, ndiko kupsinjika kwakukulu komwe chinthu chingathe kupirira chisanakhale chosinthika chokhazikika. Imawonetsa kusintha kuchokera ku khalidwe lotanuka (lobweza) kupita ku khalidwe lapulasitiki (mapindikidwe okhazikika). Kwa zigawo zamapangidwe ndi zozungulira, kupsinjika kwa zokolola zambiri kumatanthauza kugwira ntchito bwino pansi pa katundu.

Kupsinjika kwa zokolola kumayesedwa motere:

  • MPa (megapascals)

  • ksi (kilo pounds per square inchi)

Zokolola Zamphamvu za 4140 Zitsulo Zosiyanasiyana

Mphamvu zokolola za4140 aloyi zitsulozimadalira kwambiri chikhalidwe chake kutentha mankhwala. Pansipa pali mikhalidwe yodziwika bwino komanso kupsinjika kwawo komwe kumabweretsa zokolola:

1. Annealed Condition

  • Mphamvu Zokolola: 415 – 620 MPa (60 – 90 ksi)

  • Kuthamanga Kwambiri: 655 - 850 MPa

  • Kulimba: ~ 197 HB

Dongosolo lofewali limalola kuti pakhale makina abwino kwambiri koma si abwino kwa ntchito zonyamula katundu popanda kutentha kwina.

2. Normalized Condition

  • Mphamvu Zokolola: 650 - 800 MPa (94 - 116 ksi)

  • Kuthamanga Kwambiri: 850 - 1000 MPa

  • Kulimba: ~ 220 HB

Normalized 4140 yasintha mawonekedwe ake ndipo imagwiritsidwa ntchito ngati mphamvu zolimbitsa thupi.

3. Quenched and Tempered (Q&T) Condition

  • Mphamvu Zokolola: 850 - 1100 MPa (123 - 160 ksi)

  • Kuthamanga Kwambiri: 1050 - 1250 MPa

  • Kulimba: 28 - 36 HRC

Ichi ndi chikhalidwe chofala kwambiri cha mapulogalamu omwe amafunikira kupsinjika kwa zokolola zambiri. Pasakysteel, zinthu zambiri zazitsulo 4140 zimaperekedwa mumtundu wa Q&T kuti zikwaniritse zofunikira zamakina.

Chifukwa Chake Kupanikizika Kwambiri Pazokolola Kuli Kofunika?

Kuchuluka kwa zokolola kumakhudza momwe zimakhalira muutumiki. Kwa zitsulo 4140, mphamvu zokolola zambiri zimatanthauza:

  • Moyo wautali wautumikipansi pa kutsitsa mobwerezabwereza

  • Kukaniza ma deformation okhazikikam'magawo omanga

  • Kupititsa patsogolo mphamvu yonyamula katundumu zigawo zozungulira ndi zosuntha

  • Mphepete mwachitetezomu ntchito zovuta monga crane, ma axles, ndi ma shafts kubowola

Zopindulitsa izi ndizofunikira kwambiri m'mafakitale omwe kulephera kwa makina kumatha kubweretsa kutsika kwamitengo kapena kuopsa kwachitetezo.

Mapulogalamu Amene Amafuna Mphamvu Zokolola Zambiri

Chifukwa cha kupsinjika kwakukulu kwa zokolola, chitsulo cha 4140 chimagwiritsidwa ntchito m'malo osiyanasiyana okhala ndi katundu wambiri:

Zagalimoto

  • Ma axles

  • Miyendo ya gear

  • Kutumiza zigawo

  • Zigawo zoyimitsidwa

Mafuta & Gasi

  • Dulani makolala

  • Ma hydraulic silinda

  • Zida zapampu za Frac

  • Zida zolumikizana

Zamlengalenga

  • Zida zoyatsira

  • Zokwera injini

  • Zida zothandizira

Makina ndi Zida

  • Akufa okhala

  • Zolemba zolondola

  • Kulumikizana

  • Ma Crankshafts

Iliyonse mwazogwiritsa ntchito izi imayika zinthuzo kuti zichuluke kwambiri kapena kupindika, zomwe zimapangitsa kupsinjika kwa zokolola kukhala gawo lofotokozera.

4140 vs Zitsulo Zina: Kufananiza Kwamphamvu Zokolola

Tiyeni tifanizire kupsinjika kwa zokolola za 4140 ndi zitsulo zina zomwe zimagwiritsidwa ntchito kwambiri:

1045 Carbon Steel

  • Zokolola Mphamvu: 450 - 550 MPa

  • Ubwino: Yosavuta kugwiritsa ntchito makina komanso yotsika mtengo

  • Kuipa: Kutsika kwamphamvu, osati koyenera kuzinthu zolemetsa kwambiri

4340 Aloyi Chitsulo

  • Zokolola Mphamvu: 930 - 1080 MPa

  • Ubwino: Kulimba kwambiri, kukana kutopa bwino

  • Zoipa: Zokwera mtengo, zovuta kupanga makina kuposa 4140

A36 Chitsulo Chochepa

  • Zokolola Mphamvu: ~ 250 MPa

  • Ubwino: Mtengo wotsika, wowotcherera kwambiri

  • Zoyipa: Sizoyenera kuzinthu zamapangidwe zomwe zimafunikira mphamvu

Chitsulo chosapanga dzimbiri 316

  • Zokolola Mphamvu: ~ 290 MPa

  • Ubwino: Kusachita dzimbiri

  • Zoipa: Zokolola zotsika kwambiri kuposa 4140

Monga zikuwonekera,4140 imapereka kusakanikirana koyenerazamphamvu, zolimba, komanso zachuma, zomwe zimapangitsa kuti zikhale zoyenera kwa zida zomangika zomwe zimakhala zolemetsa kwambiri.

Kupititsa patsogolo Mphamvu Zokolola ndi Chithandizo cha Kutentha

At sakysteel, timagwiritsa ntchito njira zochizira kutentha kuti tipititse patsogolo makina azitsulo za 4140:

Kutentha ndi kuzizira

Zimaphatikizapo kutenthetsa chitsulo ku ~ 845 ° C ndiyeno kuziziritsa mofulumira (kuzimitsa), kutsatiridwa ndi kutenthetsanso kutentha pang'ono (kutentha). Izi zimawonjezera kupsinjika kwa zokolola, kulimba, komanso kukana kutopa.

Normalizing

Kutenthetsa chitsulo mpaka ~ 870 ° C kutsatiridwa ndi kuziziritsa kwa mpweya, kuyeretsa kapangidwe ka tirigu ndikuwonjezera mphamvu.

Kuwumitsa Pamwamba (mwachitsanzo, Nitriding, Induction Harding)

Njirazi zimawonjezera kulimba kwapamtunda ndikusunga kulimba kwapakati, kupititsa patsogolo luso lonyamula katundu.

Pokhala ndi ulamuliro wokhwima pazimenezi, sakysteel imatsimikizira kuti zitsulo zazitsulo zimagwirizana ndi zosowa za polojekiti iliyonse.

Momwe Timayesera Kupatsirana Kupsinjika pa sakysteel

Kuonetsetsa kuti chitsulo chathu cha 4140 chikukwaniritsa miyezo yamakina, timayesa zokolola komanso zolimba pogwiritsa ntchito:

  • Makina Oyesa Padziko Lonse (UTM)

  • Miyezo yoyesera ya ASTM E8 / ISO 6892

  • EN10204 3.1 satifiketi

  • Kutsimikizira kodziyimira pawokha kwa gulu lachitatu (posankha)

Gulu lililonse limatsimikiziridwa kuti likugwirizana komanso kuti likutsatira miyambo yapadziko lonse lapansi.

Nkhani Yowona Padziko Lonse

Makasitomala pagawo lamafuta & gasi adapempha zitsulo zozungulira za Q&T 4140 zokhala ndi zida zotsitsa. Tinatumiza zinthu ndi:

  • Zokolola Mphamvu: 1050 MPa

  • Kulekerera kwa Diameter: h9

  • Kumaliza Pamwamba: Kutembenuzidwa ndi kupukutidwa

  • Chitsimikizo: EN10204 3.1 + ultrasonic test (UT Level II)

Pambuyo pa miyezi 14 muutumiki, zigawozo sizinasonyeze zizindikiro za kusinthika kosatha kapena kulephera-umboni wakutisakysteelChitsulo cha 4140 chimapereka lonjezo lake.
