③ Kugirango habeho kubyara ibishishwa bidashobora kwangirika mubishushanyo byimbitse, birasabwa kugira ubukana bwa 62 ~ 64HRC.
Byakoreshejwe mugukora ibishushanyo mbonera, ibishushanyo mbonera, hamwe no gushyiramo ibice bisaba kwihanganira kwambara cyane hamwe nuburyo bugoye muburyo bwo kugonda.Birasabwa kugira ubukana bwa 60-64HRC mugihe ukora ibishushanyo mbonera, na 60-64HRC mugihe ukora ibishushanyo mbonera.
⑤ Kugirango habeho kubyara ibicuruzwa bikonje bipfa kandi bipfa kubice bya aluminiyumu, birasabwa kugira ubukana bwa 60-62HRC mugihe cyo gupfa, na 62-64HRC mugihe cyo gupfa.
⑥ Birasabwa gukoresha ubukana bwa 62 ~ 64HRC kumurongo wa convex hamwe na conve ikoreshwa mugukora umuringa ukonje.
M Ibishishwa bya convex na conave bikoreshwa mubyuma bikonje bikonje birasabwa kugira ubukana bwa 62 ~ 64HRC.
Pl Ibyapa byibyuma byamasoko bifite igice kinini cya 0,65% ~ 0,80% bikoreshwa mugukora karubone bifite ubukana bwa 37 ~ 42HRC, bitanga ubuzima bwikigihe kigera ku 150000.
Pl Ibyapa byibyuma byamasoko bifite igice kinini cya 0,65% kugeza 0.80% bikoreshwa mugukora karubone bifite ubukana bwa 37-42HRC, kandi hamwe nubuvuzi bwa nitriding, ubuzima bwabo bushobora kugera inshuro 400000.
Ⅲ-Gutunganya Cr12MoV Ubukonje bukora Die Die:
Ibisobanuro byo koroshya ifumbire ikonje: Kurinda no gushyushya ifu ukoresheje ibyuma bya 760-780 ℃ kumasaha 10, hamwe no gukonjesha itanura hamwe nubukomezi bwa 196HBW.Gukonjesha ubukonje birashobora kugerwaho neza.
Ibisobanuro kubisanzwe isothermal spheroidizing annealing: 850-870 ℃ × amasaha 3-4, gukonjeshwa mu ziko kugeza 740-760 ℃ × amasaha 4-5 yo kuvura isothermal, hamwe no gukonjesha ikirere ≤ 241HBW, ebectic carbide urwego ≤ 3, isothermal nziza ubushyuhe 740-76o ℃, nigihe ≥ amasaha 4-5.
Ibisobanuro kuri spheroidizing annealing: (860 ± 10) ℃ × amasaha 2-4, gukonjesha itanura ku gipimo cyo gukonja cya 30 ℃ / saha, (740 ± 10) ° C x amasaha 4-6, gukonja buhoro kugeza kuri 500-600 ℃ hamwe itanura, gukonjesha umwuka nyuma yo gusohoka, gukomera 207-255HBW.
Kuzimya muri rusange no gutondeka ibisobanuro: kuzimya ubushyuhe 1000-1050 ℃, kuzimya amavuta cyangwa kuzimya, ubukana 260HRC, ubushyuhe bwo hejuru 160-180, ubushyuhe bwamasaha 2, cyangwa ubushyuhe 325-375 ° C, ubushyuhe inshuro 2-3.
Kuzimya gake hamwe nubushyuhe buke bwo kuzimya: 950 ℃ -1040 ℃, ubushyuhe bwubushyuhe buri hafi 200 ℃, ubushyuhe bwa kabiri.
Kuzimya cyane no kugaruka kwinshi ubushyuhe: 1050-1100 ℃, ubushyuhe bwubushyuhe buri hafi 520 ℃, ubushyuhe bwa kabiri.Uburyo bwa kabiri bwo gukomera bukoreshwa mukuzimya cyane no gutunganya cyane byongera ubukana, ariko ibinyampeke bizakura.
Ubuvuzi bwa Cryogenic: Ibyuma bya Cr12MoV bivura cryogenic, bishobora kugabanya karbide ya ultrafine ikwirakwijwe cyane na martensite yazimye, hanyuma karbide ya ultrafine irashobora guhinduka karbide nyuma yubushyuhe bwa 200 ℃.Martensite itavuwe na kirogenike gusa igusha karbide nkeya mubice bimwe na bimwe nyuma yumuriro ukabije wubushyuhe.
zhongao ikoresha uburyo bwo kuvura ubushyuhe buke bwa chimique, ikomeza ubukana bwinshi kandi ikanambara ibyuma bya Cr12MoV.Ibice bitatu bikoreshwa cyane mubushyuhe bwo kuvura ubushyuhe buke, aribwo ion nitriding, gaz nitrocarburizing, hamwe nuyunyu wumunyu sulfur cyanide co nitriding, bifite ingaruka zikomeye zo kurwanya no gufatira hamwe, hamwe nuyunyu wumunyu sulfur cyanide co nitriding nibyiza.
Ubuzima bwa serivisi bwo gushushanya bupfa kubikoresho bya zhongao Cr12MoV ibikoresho bidafite ibyuma, nyuma yo kuvura nitrocarburizasi ya gaze, bigera ku bice birenga 30000, bikaba bikubye inshuro zirenga 10 ugereranije n’ibibumbano bisa bivurwa no kuzimya bisanzwe.
