30CRMOV9 / 1.7707 IALLOY STEEL

I-30CrMoV9 iyinsimbi ngokuvamile ehloselwe ukwakhiwa kwezingxenye ezicishiwe nezipholile, ezivame umshini bese zifakwa i-nitrided. I-alloy 30CrMoV9 ivamise ukukhiqizwa yi-EAF /VD /LF elandelwa yi-electroslag refining (ESR) uma kunesidingo ngenjongo ekhethekile. Amabha futhi, lapho kufanele, ama-forging ahlolwa nge-ultrasonic ngokusekelwe ezingeni elihlukile ngokuya ngezidingo zabathengi. Amabha ngokuvamile anikezwa ngokugqamile kusimo esifakiwe, noma ukufakwa okukhanyayo ikakhulukazi.

UKWELASHWA KOKUSHISA KWE-30CRMOV9:

1. I-Soft Annealing: Shisisa ukuya ku-680-720oC, pholisa kancane. Lokhu kuzokhiqiza ubulukhuni beBrinell obukhulu obungama-248.
2. I-Nitriding:
3. Izinga lokushisa le-nitriding yegesi//i-plasma (igesi, ibhavu likasawoti): 570-580oC
4. Ukushisa kwegesi/i-plasma nitriding (impuphu, iplasma): 580oC
5. Ukuqina kobuso ngemva kwe-nitriding: 800 HV
6. Ukuqina:Qina kusuka ekushiseni okungu-850-880oC kulandelwe ukucisha uwoyela.

I-TEMPERING OF 30CRMOV9:

• Izinga lokushisa: 570-680oC.

UKWENZIWA KWE-30CRMOV9:

• Izinga lokushisa elishisayo lokubumba: 1050-850oC.

AMAMUKO ATHOLAKALAYO :

• Ibha emnyama /Ibha eyisicaba / Ibha yesikwele /Ipayipi, /Umugqa wensimbi, /ishidi
• Bright - ehlutshiwe + epholishwa, ukugaya okungenasikhungo
• Forged – indandatho, ishubhu, isikhwama sepayipi, amadiski, umgodi

IZICELO EZIJWAYELEKILE ZAMA-30CRMOV9:

Izinsimbi zesakhiwo se-alloy zisetshenziswa kakhulu ekufakweni komkhumbi, imoto, indiza, imicibisholo eqondiswayo, izikhali, ujantshi, amabhuloho, umkhumbi wengcindezi, amathuluzi omshini, izakhi zemishini ezinosayizi omkhulu wesigaba nokunye., Amagiya omshini, shaft yegiya, main i-axis, i-valve rod, Izingxenye zemishini - induku yokuxhuma, ibhawodi namantongomane, i-Multidiameter shaft, Umkhumbi wokucindezela, ipayipi elingenamthungo
