Kodi Chitsulo cha Zida N'chiyani 1.2343 Chofanana ndi

Chitsulo cha zida ndicho maziko a mafakitale ambiri, makamaka popanga nkhungu, kuyika zinthu mochita kupanga, kupanga zinthu zotentha, ndi zida zotulutsira zinthu. Pakati pa mitundu yambiri yomwe ilipo,Chitsulo cha zida 1.2343imadziwika ndi mphamvu zake zabwino kwambiri zotentha, kulimba, komanso kukana kutopa ndi kutentha. Komabe, m'machitidwe amalonda apadziko lonse lapansi ndi uinjiniya, nthawi zambiri mumakumana ndi machitidwe osiyanasiyana otchulira mayina m'njira zosiyanasiyana monga DIN, AISI, JIS, ndi zina. Izi zikubweretsa funso lofunika kwambiri:

Kodi chifaniziro cha chitsulo cha zida 1.2343 ndi chiyani m'miyezo ina?

Nkhaniyi ifufuza za kufanana kwa mayiko ena ndiChitsulo cha zida 1.2343, katundu wake, ntchito zake, ubwino wake, ndi momwe angapezere ndalamazo modalirika kuchokera kwa ogulitsa padziko lonse lapansi mongasakysteel.

Chidule cha Chitsulo cha Zida cha 1.2343

1.2343Ndi chitsulo chogwirira ntchito chotentha malinga ndi muyezo wa DIN (Deutsches Institut für Normung) waku Germany. Chimapereka kulimba kwambiri, kukana kutentha, ndipo chimagwiritsidwa ntchito makamaka poyendetsa njinga yamagetsi, monga kupanga ndi kuyika zinthu zotentha.

Mayina Odziwika:

  • DIN: 1.2343

  • Ntchito: X37CrMoV5-1

Gulu:

  • Chitsulo Chogwiritsa Ntchito Moto

  • Chitsulo chopangidwa ndi Chromium-Molybdenum-Vanadium

Kuphatikizika kwa Mankhwala a 1.2343

Chinthu Zomwe zili mkati (%)
Kaboni (C) 0.36 – 0.42
Chromium (Cr) 4.80 – 5.50
Molybdenum (Mo) 1.10 – 1.40
Vanadium (V) 0.30 – 0.60
Silikoni (Si) 0.80 – 1.20
Manganese (Mn) 0.20 – 0.50

Kapangidwe kameneka kamapereka 1.2343 yabwino kwambirikuuma kotentha, kukhazikika kwa kutenthandikukana ming'alupansi pa ntchito zotentha kwambiri.

Chitsulo cha Zida 1.2343 Magiredi Ofanana

Nazi zofanana ndi zitsulo za 1.2343 zomwe zimadziwika kuti ndi zitsulo zamitundu yosiyanasiyana padziko lonse lapansi:

Muyezo Giredi Yofanana
AISI / SAE H11
ASTM A681 H11
JIS (Japan) SKD6
BS (UK) BH11
ISO X38CrMoV5-1

Chofanana Kwambiri:AISI H11

Pakati pa izi,AISI H11ndi chinthu chofanana kwambiri komanso chovomerezeka kwambiri. Chimafanana ndi kapangidwe kake ndi kagwiritsidwe ntchito ka makina kofanana ndi 1.2343 ndipo chimagwiritsidwa ntchito kwambiri m'misika yaku North America.

Katundu wa Makina a 1.2343 / H11

Katundu Mtengo
Kuuma (kutsekedwa) ≤ 229 HB
Kuuma (mutatha kuumitsa) 50 - 56 HRC
Kulimba kwamakokedwe 1300 – 2000 MPa
Kusinthasintha kwa Kutentha kwa Ntchito Kufikira 600°C (mu ntchito zina)

Kuphatikiza kwa kulimba ndi kulimba kofiira kumeneku kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo otentha.

Zinthu Zazikulu ndi Ubwino

  1. Mphamvu Yotentha Kwambiri
    Imasunga kuuma ndi mphamvu yokakamiza pa kutentha kwakukulu.

  2. Kulimba Kwambiri
    Kukana kwambiri kutentha, ming'alu, ndi kutopa.

  3. Kugwira Ntchito Mwabwino
    Mu mkhalidwe wophimbidwa ndi annealed, imapereka makina abwino musanagwiritse ntchito kutentha.

  4. Kukana Kuvala ndi Kutupa
    Dongosolo lake lopangira Cr-Mo-V limapereka kukana kukalamba pansi pa kutentha kozungulira.

  5. Kugwirizana kwa Chithandizo cha Pamwamba
    Yoyenera kupangidwa ndi nitriding, PVD covering, ndi kupukuta.

Kugwiritsa ntchito 1.2343 ndi Zofanana Zake

Chifukwa cha kukana kutentha kwambiri komanso kulimba kwake pamene akupanikizika, 1.2343 (H11) imagwiritsidwa ntchito kwambiri m'magwiritsidwe ntchito otsatirawa:

  • Hot forging dies

  • Zipangidwe zoponyera kufa

  • Mafa a Extrusion a aluminiyamu, mkuwa

  • Zipangidwe zapulasitiki (zokhala ndi ma resin otentha kwambiri)

  • Zida za ndege ndi zamagalimoto

  • Mandrels, nkhonya, ndi kuika

Chitsulochi chimayamikiridwa kwambiri pa ntchito zomwe zimafuna mphamvu zambiri komanso kukana kutentha.

Njira Yothandizira Kutentha

Kusamalira kutentha koyenera n'kofunika kwambiri kuti ntchito iyende bwino kwambiri. Njira yodziwika bwino imaphatikizapo:

1. Kuphimba Kofewa

  • Tenthetsani mpaka 800 – 850°C

  • Gwirani ndipo muziziziritse pang'onopang'ono

  • Kuuma kotsatira: max 229 HB

2. Kuuma

  • Yatsani kutentha kufika pa 600 - 850°C

  • Konzani kutentha pa 1000 - 1050°C

  • Kuzimitsa mu mafuta kapena mpweya

  • Kufikira 50 - 56 HRC

3. Kulimbitsa thupi

  • Chitani zinthu zitatu zotenthetsera

  • Kutentha koyenera kotenthetsera: 500 - 650°C

  • Kuuma komaliza kumadalira kuchuluka kwa kutentha

Kuchiza ndi Kumaliza Pamwamba

Pofuna kulimbitsa kuuma kwa pamwamba ndi moyo wautali m'malo opangira zida, 1.2343 (H11) ikhoza kuchiritsidwa ndi:

  • Kutaya madzikuti pakhale kukana kuvala pamwamba

  • Zophimba za PVDmonga TiN kapena CrN

  • Kupukutakugwiritsa ntchito magalasi omalizitsa mu zida za nkhungu

Kuyerekeza: 1.2343 motsutsana ndi 1.2344

Giredi Zamkati mwa Cr Kutentha Kwambiri Kulimba Chofanana
1.2343 ~5% ~600°C Zapamwamba AISI H11
1.2344 ~5.2% ~650°C Pansi pang'ono AISI H13

Ngakhale kuti zonsezi ndi zitsulo zotentha,1.2343ndi wolimba pang'ono, pomwe1.2344 (H13)imapereka kuuma kwakukulu kwa kutentha.

Momwe Mungasankhire Chofanana Choyenera

Posankha chinthu chofanana ndi 1.2343 pa pulojekiti, ganizirani izi:

  • Kutentha Kogwira Ntchito:H13 (1.2344) ndi yabwino kwambiri kutentha kwambiri.

  • Zofunikira pakukula:1.2343 imapereka kukana kwabwino kwambiri kwa ming'alu.

  • Kupezeka kwa Zigawo:AISI H11 imapezeka mosavuta ku North America.

  • Zofunikira Zomaliza:Pa nkhungu zopukutidwa, onetsetsani kuti ndi zaukhondo kwambiri.

Komwe Mungayambitsire Chida cha 1.2343 / H11 Chitsulo

Kupeza wogulitsa wodalirika komanso wodziwa zambiri ndikofunikira. Yang'anani makampani omwe:

  • Perekani satifiketi yonse ya zinthu (MTC)

  • Perekani zonse ziwiri zosalala komanso zozungulira m'makulidwe osiyanasiyana

  • Lolani kudula mwamakonda kapena kukonza pamwamba

  • Khalani ndi chithandizo chapadziko lonse lapansi cha kayendetsedwe ka zinthu

sakysteelndi kampani yodalirika yogulitsa zitsulo zogwirira ntchito kuphatikizapo DIN 1.2343, AISI H11, ndi zina zogwirira ntchito zotentha. Ndi chidziwitso chambiri padziko lonse lapansi,sakysteelkuonetsetsa kuti:

  • Mitengo yopikisana

  • Ubwino wokhazikika

  • Kutumiza mwachangu

  • Thandizo laukadaulo

Mapeto

Chitsulo cha zida 1.2343ndi chida chogwirira ntchito chotentha chapamwamba kwambiri chomwe chimagwiritsidwa ntchito kwambiri popanga zida zopangira, kuyika zinthu mopanda madzi, ndi zida zotulutsira zinthu. Chofanana nacho chofala kwambiri ndiAISI H11, yomwe ili ndi makhalidwe ofanana a mankhwala ndi makina. Zina zofanana ndi izi ndi SKD6 ndi BH11, kutengera dera.

Mwa kumvetsetsa zofananazo ndikusankha giredi yoyenera kugwiritsa ntchito kwanu, mutha kuwonetsetsa kuti zida zanu zikugwira ntchito bwino komanso kuti zikugwira ntchito bwino. Kuti mupeze zabwino zonse komanso kutumiza zinthu padziko lonse lapansi, sankhani wogulitsa waluso ngatisakysteelamene amamvetsetsa zosowa za ogwiritsa ntchito zida zachitsulo padziko lonse lapansi.
