30CRMOV9 / 1.7707 Intsimbi ye-ALLOY

I-30CrMoV9 yintsimbi ejongiswe ngokubanzi ukwenza iindawo ezicinyiweyo nezipholileyo, ezisebenza ngoomatshini kwaye emva koko zifakwe nitridi. I-alloy 30CrMoV9 idla ngokuveliswa yi-EAF /VD /LF ilandelwa yi-electroslag refining (ESR) ukuba kuyimfuneko ngenjongo ekhethekileyo. Iibhari kwaye, apho kufanelekileyo, i-forgings ixhomekeke kuvavanyo lwe-ultrasonic ngokusekelwe kwinqanaba elahlukileyo ngokweemfuno zabathengi. Iibha zidla ngokubonelelwa ngokuqaqambileyo kwimeko efakiweyo, okanye i-annealing eqaqambileyo ingakumbi.

UNYANGO LWE-30CRMOV9:

1. I-Soft Annealing: Fudumeza ukuya kwi-680-720oC, pholile ngokucothayo. Oku kuya kuvelisa ubulukhuni beBrinell obungama-248.
2. Nitriding:
3. Irhasi/iqondo lobushushu leplasma nitriding (igesi, ibhafu yetyuwa): 570-580oC
4. Ubushushu begesi ye-plasma nitriding (umgubo, iplasma): 580oC
5. Ukuqina komphezulu emva kwe-nitriding: 800 HV
6. Ukuqina: Ukuqina ukusuka kubushushu obuyi-850-880oC kulandele ukucima i-oyile.

UKUBUKA KWE-30CRMOV9:

• Ubushushu bobushushu: 570-680oC.

UKWENZIWA KWE-30CRMOV9:

• Ubushushu bokwenza okushushu: 1050-850oC.

IIMILO EZIFUMANEKAYO :

• Ibar emnyama /Ibha eflethi / Ibar yesikwere /Ipayipi, /Imigca yentsimbi, /ishiti
• Kuqaqambile - kuxotyulwe + ukupolisha, ukugawula okungenaziko
• Yenziwe ngomsesane, ityhubhu, ibhokisi yombhobho, iidiski, ishaft
