25Cr2MoVA urupapuro rushyushye

Imibare ibiri ku ntangiriro yumubare wibyuma yerekana karubone yibyuma, bigaragarira mubihumbi icumi byikigereranyo cya karubone, nka 40Cr, 25Cr2MoVA
HeIbintu nyamukuru bivanga mubyuma, usibye ibice bya microalloying kugiti cye, mubisanzwe bigaragarira mubice bike. Iyo impuzandengo ya alloy iboneka iri munsi ya 1.5%, mubisanzwe gusa ikimenyetso cyibintu cyerekanwe mumibare yicyuma, kandi ibirimo ntabwo byerekanwe. Ariko, mubihe bidasanzwe, biroroshye gutera urujijo, kandi umubare "1" urashobora kandi gushyirwaho ikimenyetso nyuma yikimenyetso cyibintu, nkumubare wibyuma "12CrMoV" na "12Cr1MoV", uwambere afite chromium irimo 0.4-0.6 %, iyanyuma ifite chromium irimo 0.9-1.2%, naho ibindi byose ni bimwe. Mugihe impuzandengo yibintu bivangavanze ari .51.5%, .52.5%, .53.5% ..., ibirimo bigomba kwerekanwa nyuma yikimenyetso cyibintu, bishobora kugaragazwa nka 2, 3, 4 ... nibindi Urugero , 18Cr2Ni4WA.
Ibintu bivanga nka vanadium V, titanium Ti, aluminium AL, boron B, nubutaka budasanzwe RE mubyuma nibintu byose bya microalloying. Nubwo ibirimo biri hasi cyane, bigomba gukomeza gushyirwaho nimero yicyuma. Kurugero, muri 20MnVB ibyuma. Vanadium ni 0.07-0.12%, na boron ni 0.001-0.005%.
SteelIcyuma cyo mu rwego rwo hejuru cyujuje ubuziranenge kigomba kongeramo "A" nyuma yumubare wibyuma kugirango ubitandukanye nicyuma rusange cyiza cyane.
Purpose Intego idasanzwe ivanze ibyuma byubatswe, nimero yicyuma ibanziriza (cyangwa yongeweho) hamwe nikimenyetso cyerekana intego yicyuma. Kurugero, 30CrMnSi ibyuma bidasanzwe byo kugorora imigozi, nimero yicyuma igaragazwa nka ML30CrMnSi.
Imiyoboro ivanze hamwe nu miyoboro idafite icyerekezo byombi bifitanye isano kandi bitandukanye, kandi ntibigomba kwitiranywa.
Umuyoboro wa Alloy usobanurwa numuyoboro wibyuma ukurikije ibikoresho byakozwe (ni ukuvuga ibikoresho), nkuko izina ribivuga, ni umuyoboro wakozwe mu mavuta; mugihe umuyoboro udafite icyerekezo usobanurwa numuyoboro wibyuma ukurikije uburyo bwo kubyaza umusaruro (bidafite ikidodo kandi bidafite ikidodo), itandukaniro ryumuyoboro utagira ikidodo ni imiyoboro ya Seam, harimo imiyoboro igororotse isudira hamwe nu miyoboro izenguruka.

Treatment Kuvura ubushyuhe】
Kuzimya ubushyuhe bwo gushyushya (℃): 900; gukonjesha: amavuta
Ubushyuhe bwo gushyushya ubushyuhe (℃): 640; gukonjesha: ubusa

Turashobora kubyara 25Cr2MoVA ifite ibisobanuro bikurikira:

Icyuma kizunguruka: 1mm kugeza 3000mm

Icyuma kimeze nka kare: 1mm kugeza 2000mm

Icyuma cy'isahani: 0.1mm kugeza kuri 2500mm

Ubugari: 10mm kugeza 2500mm

Icya cumi: Turashobora gutanga inguzanyo iyo ari yo yose dukurikije ibyo umukiriya asabwa.

Guhimba: Igiti gifite impande / imiyoboro / igituba / igituba / inkongoro / cubes / izindi shusho

Ibibyimba: OD: φ6-219 mm, uburebure bwurukuta buri hagati ya mm 1-35.

Ibicuruzwa byarangiye neza: guhimba bishyushye / kuzunguruka bishyushye + annealing / bisanzwe + ubushyuhe / kuzimya + ubushyuhe / ibisabwa byose ukurikije ibyo umukiriya asabwa

Imiterere yubuso: yapimwe (irangije gukora ishyushye) / ubutaka / gutunganya nabi / gutunganya neza / ukurikije ibyo umukiriya asabwa

Amatanura yo gutunganya ibyuma: electrode arc + LF / VD / VOD / ESR / Vacuum ikoreshwa na electrode.

Igenzura rya Ultrasonic: Igenzura rya ultrasonic 100% kubitagenda neza cyangwa ukurikije ibyo umukiriya asabwa Serivisi nziza yinganda zose, hamwe nibyiza byikoranabuhanga, ibikoresho nibiciro.
