Yadda za a tabbatar da yanayin da ake bukata don ingancin induction dumama kayan kashe wuta

1. M sassa sassa uzuri zane da pre-zafi magani bukatun

Tsarin tsarin ɓangaren ya kamata ya dace da halaye na dumama shigarwa, kuma tsarin tsarinsa ya kamata ya kasance da sauƙi don samun dumama iri ɗaya. Ya kamata ya dace da buƙatun fasaha na induction zafi magani, ana buƙatar sassan da za a yi zafi kafin su, kuma sassan da ke buƙatar ingantacciyar juriya na lalacewa gabaɗaya an daidaita su; sassan ko sassa na katanga masu sirara waɗanda ke buƙatar ƙarfi mai ƙarfi da juriya mai tsayi gabaɗaya ana kashe su da fushi. .

2. Zaɓin daidaitattun sassa da kayan aiki, tsari mai dacewa na hanyoyin sarrafawa

Ya dace gabaɗaya a yi amfani da ƙarfe mai ƙaƙƙarfan ƙima a matsayin kayan shigar da sassan jiyya mai zafi. Hakanan sassa na musamman suna buƙatar zaɓin abun cikin carbon na ƙarfe. Karfe da aka fi amfani dasu sune: 35, 40, 45, 50, ZG310-570, 40Cr, 45Cr35rMo, 42CrMo, 40MnB da 45MnB, da dai sauransu.

Simintin ƙarfe da aka fi amfani da shi sun haɗa da: baƙin ƙarfe simintin gyare-gyare, simintin simintin ƙarfe, baƙin ƙarfe mai launin toka da baƙin ƙarfe.

Abun lu’u-lu’u (ƙarashin juzu’i) na nodular simintin ƙarfe don shigar da maganin zafi ana bada shawarar ya zama 75% ko fiye. Ya fi dacewa da abun ciki na pearlite (ƙarashin juzu’i) ya zama mafi girma fiye da 85%, kuma siffar pearlite ya fi dacewa flake; Ƙarfin simintin gyare-gyare yana buƙatar kwatanta graphite a yanka da kyau kuma a rarraba daidai.

3. Abubuwan da ake buƙata don sassa kafin quenching

(1) Abubuwan sassan sun hadu da ka’idojin ƙira.

(2) Filayen sassan yana da tsabta kuma babu mai da ƙarfe.

(3) Babu lahani kamar kumbura, tsagewa, lalata, da sikelin oxide akan saman sassan.

(4) Matsakaicin matsi na ɓangaren da aka kashe a saman ɓangaren ya kamata ya zama daidai ko mafi kyau fiye da Ra6.3μm, dole ne a sami wani Layer na decarburization, burrs, crushing, da dai sauransu.

(5) The sassa sun sha normalizing da quenching da tempering a gaba bisa ga tsari ka’idojin, da kuma taurin hadu da bukatun. Girman hatsi na tsarin metallographic ya kamata ya zama 5-8.

(6) Ma’auni na geometric na sassan sun hadu da buƙatun tsari, kuma babu matakan da suka ɓace ko fiye da tsari.
