Ⅲ-Habaynta of Cr12MoV Qabow Shaqaynta Dhirta Birta:
Sifaynta 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 oo ah daaweynta isothermal, oo leh hawo qaboojin adag≤241HBW, fasalka eutectic carbide≤3, heerkulka isothermal ugu fiican 740-76o℃, iyo waqti≥4-5 saacadood.
Sharaxaadda spheroiding annealing: (860± 10)℃ ×2-4 saacadood, foornada qaboojinta heerkulka qaboojinta ee 30℃/saac, (740± 10)° C x 4-6 saacadood, si tartiib ah u qaboojin ilaa 500-600℃foornada, qaboojinta hawada ka dib dheecaanka, adkaanta 207-255HBW.
Deminta guud iyo qeexida heerkulka: deminta heerkulka 1000-1050℃, Deminta saliidda ama deminta, adkaanta 260HRC, heerkulka heerkulka 160-180, wakhtiga heerkulka 2 saacadood, ama heerkulka heerkulka 325-375° C, kululaynta 2-3 jeer.
Deminta hooseeya iyo heerkulka deminta soo laabashada hoose: 950℃-1040℃, heerkulka kulaylku waa ku dhawaad 200℃, xanaaqa sare.
Deminta sare iyo soo celinta heerkulka sare ee deminta: 1050-1100℃Heerkulku waa ku dhawaad 520℃, xanaaqa 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 birta waxay martaa daawaynta cryogenic, taas oo soo dedejin karta karbohidraatka ultrafine ee aadka u kala firdhiyey ee martensite la demiyo, ka dibna kuwan ultrafine carbide waxa loo bedeli karaa carbide ka dib 200℃heerkulka hooseeya.Martensite-ka oo aan lahayn daawaynta cryogenic ayaa kaliya soo dejisa qadar yar oo carbide ah meelaha maxalliga ah ka dib marka heerkulku hooseeyo.
Jinbaicheng 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 bath bath 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 sawirku waxay u dhintaa Jinbaicheng's Cr12MoV maacuunta birta ah, ka dib daawaynta nitrocarburization gaaska, waxay gaartaa in ka badan 30000 xabo, taas oo ka badan 10 jeer in ka badan kuwa caaryada la midka ah ee lagu daweeyay deminta iyo xanaaqa caadiga ah.
