Izizathu zokuthi kungani ubulukhuni be ukungeniswa kwaqina izingxenye azihlangabezani nezidingo zobuchwepheshe

1. Izinga lokushisa lokucisha alanele

Okusho ukuthi, ukushisa akwanele futhi imfuneko yokushisa ye-austenitizing ayifinyelelwanga. Ngensimbi yesakhiwo sekhabhoni ephakathi, kukhona i-ferrite engancibilikisiwe ku-austenite, futhi kukhona i-ferrite engancibilikisiwe esakhiweni esicishiwe ngaphandle kwe-martensite, futhi indawo ecishiwe ye-workpiece ngokuvamile iluhlaza okwesibhakabhaka. Kungabonakala futhi ekubukeni kwezingxenye eziqinile zokungeniswa ukuthi indawo evamile yokucisha i-beige, futhi indawo eshisa ngokweqile imhlophe.

2. Ukupholisa okunganele

Okusho ukuthi, izinga lokupholisa liphansi kunezinga lokupholisa elibalulekile. Esakhiweni esicishiwe, ngaphezu kwengxenye ye-martensite, kukhona ne-tortenite, futhi inani elikhulu le-tortenite, liyancipha ubulukhuni. Kuvame ukwenzeka lapho ukugxila kwe-medium quenching, izinga lokushisa, ingcindezi ishintsha futhi imbobo yomjovo we-liquid ivinjiwe.

3. Izinga lokushisa lokuzibamba liphezulu kakhulu

Inkinga yezinga lokushisa eliphakeme ngokwedlulele le-self-tempering yenzeka ekucimeni kwe-shaft scanning, okuvame ukwenzeka ngesikhathi sokucisha i-shaft evundlile noma ukucisha kwe-shaft okunyathelwe kuqondile. Lapho ububanzi bejethi eliwuketshezi bufushane, indawo yokushisa idlula ngokushesha i-jet ye-liquid futhi ayipholisi isigaba sokucisha ngokwanele, futhi ukugeleza kwamanzi kuvinjelwa izinyathelo (isigaba esikhulu sobubanzi siphezulu, ingxenye encane yobubanzi. ingaphansi), futhi ingxenye ecishiwe ayikwazi ukuqhubeka nokupholiswa. Ngenxa yalokho, amazinga okushisa abonakala ekwazi ukuzibamba avame ukubonwa futhi atholakale endaweni ecishiwe.

4. Indawo ethambile noma ibhande elimnyama eli-spiral

Amabala athambile namabhulokhi endaweni ecishiwe kuvame ukuba mnyama, futhi ibhande elimnyama elivunguzayo liyisici esivamile sokuskena izingxenye ezicishiwe. Leli bhande elimnyama libizwa nangokuthi ibhande elithambile, futhi ngokuvamile liyisakhiwo se-tortite. Isixazululo ukufafaza uketshezi ngokulinganayo, futhi ukwandisa ijubane lokujikeleza kwe-workpiece kunganciphisa futhi i-pitch yebhande elimnyama, kodwa into eyisisekelo kakhulu ukuthi isakhiwo se-sprayer se-liquid kufanele senze indawo yokushisa ipholile ngokulinganayo. Izimbobo zejethi ezivalekile zivame ukuba ngenye yezimbangela zamabala athambile.

5. Ithonya lokwakheka kwamakhemikhali

Ukuncishiswa kokwakheka kwezinto, ikakhulukazi okuqukethwe kwekhabhoni, kungenye yezinto zokunciphisa ubulukhuni. Uma kunesidingo, okuqukethwe kwekhabhoni ekhethiwe kungasetshenziswa ezingxenyeni ezibalulekile, ukuze umkhawulo ongaphezulu nophansi we-w(C) ungancishiswa ube phakathi kuka-0.05%.

6. Ukwelashwa kokushisa okulungiselelayo

Izinguquko enqubweni yokucisha nokushisa, futhi isikhumba esimnyama sezinto ezigoqiwe sihlala endaweni yokucisha futhi yizizathu zokuthi kungani ukuqina kwezingxenye eziqinile zokungeniswa akuhlangabezani nezidingo zobuchwepheshe.

7. I-surface decarburization kanye ne-decarbonization

Kuvame ukuvela ebusweni bezinto ezikhandwayo ezibandayo. Ngakho-ke, ngemva kokucisha le migoqo, ungqimba lwangaphandle lungagaywa ngo-0.5mm ngaphambi kokuqina. Uma ubulukhuni bobuso buphansi, ubulukhuni bengqimba yangaphakathi buphakeme kunobuphezulu, okubonisa ukuthi kukhona ungqimba oluncishisiwe lwekhabhoni noma olukhishwe yi-decarburized. (ngaphandle kwamajometri akhethekile njengama-cam lobes, amagiya angaphezulu).

8. Izicubu zakuqala zeribhoni

Isakhiwo esihlanganisiwe esakhiweni sokuqala sengxenye ecishiwe sizoholela ebukhuni obanele ngemva kokucisha. Kukhona i-ferrite engaqediwe esakhiweni esihlanganisiwe, esingenakuqedwa ngesikhathi senqubo ye-austenitization, futhi ukuqina ngemva kokucisha akwanele, futhi isakhiwo esihlanganisiwe sinzima ukuqeda ngisho noma ukushisa kwanda.
