⑥ Waxaa lagu talinayaa in la isticmaalo a engegnaanta 62 ~ 64HRC for convex iyo caaryada concave loo isticmaalo samaynta naxaas qabow caaryada extrusion.
⑦ Koofiyadaha iyo caaryada concave ee loo isticmaalo caarada qabow ee birta ayaa lagula talinayaa in ay yeeshaan adkaanta 62 ~ 64HRC.
Taarikada birta guga oo leh jajab tiro badan oo ah 0.65% ~ 0.80% loo isticmaalo samaynta kaarboon waxay leeyihiin adkaanta 37 ~ 42HRC, oo siinaya cimri dherer ah ilaa 150000 wareegyo.
⑨ Taarikada birta guga oo leh jajab tiro badan oo ah 0.65% ilaa 0.80% loo isticmaalo samaynta kaarboonku waxay leeyihiin adkaanta 37-42HRC, iyo daawaynta nitriding dheeraad ah, adeegooda waxay gaari kartaa 400000 jeer.
Ⅲ-Ka-habaynta Cr12MoV Qabow ku shaqaynaysa birta:
Sifeynta jilcinta caaryada qabowga ee extrusion: Ka ilaali oo ku kululee caaryada galka birta heerkul ah 760-780 ℃ 10 saacadood, oo leh qaboojinta foornada iyo adkaanta 196HBW.Samaynta extrusion qabow waxaa lagu gaari karaa si habsami leh.
Sharaxaada kanaalkaaga: 850-870 ℃ × 3-4 saacadood, lagu qaboojiyey foornada ilaa 740-760 ℃ × 4-5 saacadood ee daaweynta isothermal, oo leh qallafsanaan hawo qaboojin ≤ 241HBW, eutectic carbide fasalka ugu fiican, 3 heerkulka 740-76o ℃, iyo waqtiga ≥ 4-5 saacadood.
Tilmaamaha soo-saarista spheroidizing: (860 ± 10) ℃ × 2-4 saacadood, qaboojinta foornada heerka qaboojinta ee 30 ℃ / saac, (740 ± 10) ° C x 4-6 saacadood, si tartiib tartiib ah u qaboojin ilaa 500-600 ℃ foornada, qaboojinta hawada ka dib dheecaanka, adkaanta 207-255HBW.
Deminta guud iyo qeexida heerkulka: heerkulka deminta 1000-1050 ℃, deminta saliidda ama deminta, adkaanta 260HRC, heerkulka heerkulka 160-180, heerkulka heerkulka 2 saacadood, ama heerkulka heerkulka 325-375 ° C, heerkulka 2-3 jeer.
Deminta hoose iyo soo laabashada hooseysa heerkulka deminta: 950 ℃ -1040 ℃, heerkulka kulaylku waa agagaarka 200 ℃, heerkulka sare.
Deminta sare iyo dib u soo celinta heerkulka sare ee deminta: 1050-1100 ℃, heerkulka heerkulka waa agagaarka 520 ℃, heerkulka sare.Habka qallafsanaanta labaad ee loo isticmaalo deminta sare iyo dib u warshadaynta sare waxay hagaajinaysaa adkaanta, laakiin miraha way kori doonaan.
Daawaynta Cryogenic: Cr12MoV steel waxa lagu daweeyaa daawaynta cryogenic, taas oo soo dedejin karta ultrafine karbides-ka aadka u kala firdhiyey ee martensite la demiyo, ka dibna carbides-ka ultrafine waxa loo bedeli karaa carbides ka dib 200 ℃ heerkulka heerkulka hooseeya.Martensite-ka oo aan lahayn daawaynta cryogenic ayaa kaliya soo dejisa qadar yar oo carbide ah meelaha maxalliga ah ka dib marka heerkulka hoose uu hooseeyo.
zhongao waxay qabataa habka daawaynta kulaylka kiimiko heer-ku-hooseeya, kaas oo ilaalinaya adkaanta sare iyo xidhashada caabbinta birta Cr12MoV.Saddexda lakab ee daawaynta kulaylka kiimikaad hooseeya ee sida caadiga ah loo isticmaalo, kuwaas oo ah ion nitriding, gaaska nitrocarburizing, iyo qubeyska cusbada sulfur cyanide co nitriding, waxay leeyihiin saamayn wayn iska caabin iyo adhesion, oo leh qubeyska sulfur cyanide co nitriding waa kan ugu fiican.
Nolosha adeegga ee sawirku waxay u dhintaa zhongao's Cr12MoV maacuunta birta ah, ka dib daawaynta nitrocarburization gaaska, waxay gaartaa in ka badan 30000 oo xabbo, taas oo ka badan 10 jeer ka badan kuwa la midka ah ee lagu daaweeyay deminta caadiga ah iyo xanaaqa.
