Ipayipi yensimbi engu-35CrMo

Incazelo emfushane:

Ukucaciswa kokukhiqiza:

Ububanzi bangaphandle bepayipi lensimbi 20-426

Ipayipi lensimbi odongeni ukujiya 20-426

Isingeniso somkhiqizo:

Isibonelo, i-40Cr.(Okuqukethwe kwekhabhoni kwepayipi lensimbi elingu-35CrMo ngu-0.32~0.40, i-silicon 0.17~0.37, i-manganese 0.40~0.70, i-molybdenum 0.15~0.25, i-chromium 0.80~1.10)

② Izakhi eziyinhloko ze-alloying kunsimbi, ngaphandle kwamanye ama-microalloying, ngokuvamile zivezwa ngamaphesenti ambalwa.Uma isilinganiso sokuqukethwe kwe-alloy singaphansi kuka-1.5%, uphawu lwe-elementi kuphela oluvame ukumakwa enombolweni yensimbi, kodwa hhayi okuqukethwe.Kodwa-ke, ezimweni ezikhethekile, kulula ukudideka, inombolo ethi "1" ingamakwa ngemuva kophawu lwesici, njengenombolo yensimbi "12CrMoV" kanye "12Cr1MoV", okuqukethwe kwe-chromium yangaphambili ngu-0.4-0.6%, futhi lokho kwakamuva kungu-0.9-1.2%.Konke okunye kuyefana.Uma isilinganiso sokuqukethwe kwe-elementi ye-alloying ≥1.5%, ≥2.5%, ≥3.5%…… “, uphawu lwe-elementi kufanele limakwe ngemva kokuqukethwe, lungavezwa njengokuthi 2, 3, 4…… Njll. Ngokwesibonelo, 18Cr2Ni4WA.

③ Ama-elementi e-alloy afana ne-vanadium V, i-titanium Ti, i-aluminium AL, i-boron B kanye nomhlaba ongavamile RE ensimbi kuyingxenye ye-microalloying.Nakuba okuqukethwe kuphansi kakhulu, kusafanele kumakwe enombolweni yensimbi.Isibonelo, ku-20MnVB steel.I-Vanadium ingu-0.07-0.12% futhi i-boron ingu-0.001-0.005%.

④ U-“A” kufanele wengezwe ekugcineni kwenombolo yensimbi yezinga eliphezulu ukuze ihlukanise kusukela kunsimbi yekhwalithi ephezulu evamile.

⑤ I-alloy structural iron yenhloso ekhethekile, isiqalo senombolo yensimbi (noma isijobelelo) simele injongo yophawu lwensimbi.Isibonelo, insimbi ye-30CrMnSi esetshenziselwa ngokukhethekile izikulufi zokuqhumisa ivezwa njenge-ML30CrMnSi.

Ishubhu yengxubevange neshubhu engenamthungo zombili zinobudlelwano nomehluko, azikwazi ukudideka.

Ipayipi ye-alloy ipayipi yensimbi ngokuhambisana nezinto zokukhiqiza (okungukuthi, izinto ezibonakalayo) ukuchaza, njengoba igama libonisa ukuthi lenziwe ngepayipi le-alloy;Futhi ipayipi Seamless kuyinto ipayipi steel ngokuhambisana nenqubo yokukhiqiza (seamless) ukuchaza, ehlukile ipayipi nekhono is ashiselwe ipayipi, kuhlanganise iqonde umthungo ipayipi ashiselwe kanye ipayipi Kuvunguza.

Ubuchwepheshe bokukhiqiza:

1. Ukuginqika okushisayo (ipayipi lensimbi eli-extrusion elingenamthungo) : ishubhu eliyindilinga alinalutho → ukushisisa → ukumboza → ukugoqa okudayagonali okuphakeme kathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula → ukusika (noma ukunciphisa) → ukupholisa → ukuqondisa → ukuhlolwa kwe-hydrostatic (noma ukuhlola) → ukumaka → isitoreji

2. Ipayipi lensimbi elikhaza (eligoqiwe) elingenamthungo: ishubhu eliyindilinga alinalutho → ukushisisa → ukubhoboza → isihloko → ukubhoboza → ukugcoba → ukugcoba → ukugcoba (i-copper plating) → umdwebo obandayo onamapayipi amaningi (ukugoqeka okubandayo) → ishubhu elingenalutho → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa kwe-hydrostatic (ukuhlola) → ukumaka → isitoreji
