25Cr2MoVA ishidi lensimbi eligoqiwe elishisayo

① Amadijithi amabili ekuqaleni kwenombolo yensimbi abonisa okuqukethwe kwekhabhoni yensimbi, evezwe ngezinkulungwane eziyishumi zesilinganiso sokuqukethwe kwekhabhoni, njenge-40Cr, 25Cr2MoVA alloy tube
②Izinto eziyinhloko ze-alloying kunsimbi, ngaphandle kwama-elementi e-microalloying ngayinye, ngokuvamile zivezwa ngamaphesenti ambalwa. Uma isilinganiso sokuqukethwe kwe-alloy singaphansi kuka-1.5%, ngokuvamile uphawu lwesici kuphela olukhonjiswa enombolweni yensimbi, futhi okuqukethwe akubonisiwe. Nokho, ezimweni ezikhethekile, kulula ukubangela ukudideka, futhi inombolo "1" ingabuye imakwe ngemva kophawu lwesici, njengenombolo yensimbi "12CrMoV" kanye "12Cr1MoV", eyangaphambili inokuqukethwe kwe-chromium engu-0.4-0.6 %, lokhu kokugcina kunokuqukethwe kwe-chromium okungu-0.9-1.2%, kanti okunye kuyafana. Uma isilinganiso sokuqukethwe sezakhi ze-alloying sithi ≥1.5%, ≥2.5%, ≥3.5%..., okuqukethwe kufanele kuboniswe ngemva kophawu lwe-elementi, olungavezwa njengo-2, 3, 4... njll. Isibonelo , 18Cr2Ni4WA.
③ Ama-elementi e-alloying afana ne-vanadium V, i-titanium Ti, i-aluminium AL, i-boron B, kanye ne-earth engavamile RE ensimbi zonke ziyizakhi ezincane ze-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%.
④Insimbi yekhwalithi ephezulu yezinga eliphezulu kufanele yengeze okuthi "A" ekugcineni kwenombolo yensimbi ukuze ihlukanise kusukela kunsimbi yekhwalithi ephezulu evamile.
⑤ Insimbi yesakhiwo esinenhloso ekhethekile, inombolo yensimbi inesiqalo (noma ifakwe isijobelelo) enophawu olumelela injongo yensimbi. Isibonelo, insimbi engu-30CrMnSi ekhethekile yezikulufi zokudonsa, inombolo yensimbi ivezwa njenge-ML30CrMnSi.
Amapayipi e-alloy namapayipi angenamthungo ahlobene futhi ahlukene, futhi akufanele adideke.
Ipayipi ye-alloy ichazwa ngepayipi yensimbi ngokusho kwempahla yokukhiqiza (okungukuthi, impahla), njengoba igama lisho, ipayipi eyenziwe nge-alloy; kuyilapho ipayipi elingenamthungo lichazwa ngepayipi lensimbi ngokuya ngenqubo yokukhiqiza (ayinamthungo futhi ayinamthungo), umehluko osuka kumapayipi angenamthungo amapayipi omthungo, okuhlanganisa amapayipi ashiselwe ngomthungo oqondile kanye namapayipi asongezelayo.

【Ukwelashwa Kokushisa】
Ukucima izinga lokushisa lokushisa (℃): 900; ukupholisa: amafutha
Izinga lokushisa elishisayo (℃): 640; okupholisayo: akunalutho

Singakhiqiza i-25Cr2MoVA inokucaciswa okulandelayo:

Insimbi yebha eyindilinga: 1mm ukuya ku-3000mm

Insimbi yomumo wesikwele: 1mm ukuya ku-2000mm

Plate steel: 0.1mm ukuze 2500mm

Ububanzi: 10mm ukuya ku-2500mm

I-Lenth: Singakwazi ukunikeza noma iyiphi i-lenth ngokusekelwe kwimfuneko yekhasimende.

Ukuqamba: Ama-Shaft anama-flanks/amapayipi/amashubhu/slugs/ama-donuts/ama-cubes/ezinye izimo

Amashubhu: OD: φ6-219 mm, anogqinsi olusuka ku-1-35 mm.

Isimo sezimpahla eziqediwe: i-hot forging/hot rolling + annealing/normalizing + tempering/quenching + tempering/noma yiziphi izimo ezisekelwe kwimfuneko yekhasimende

Izimo ezingaphezulu: okukaliwe (ukuphela kokusebenza okushisayo)/ground/machine rough/fine machineing/ngokusekelwe kwimfuneko yekhasimende

Iziko lokucutshungulwa kwe-metallurgical: electrode arc + LF/VD/VOD/ESR/Vacuum consumable electrode.

Ukuhlola nge-Ultrasonic: 100% Ukuhlolwa kwe-ultrasonic kwanoma yikuphi ukungapheleli noma okusekelwe kumfuneko yekhasimendeIsevisi enhle kakhulu yazo zonke izinhlobo zezimboni, ngezinzuzo zobuchwepheshe, okokusebenza kanye nentengo.

Sisebenzela wena ngokwethembeka, ubuqotho, kanye nobuchwepheshe.
