Ⅰ-Ni ikiCr12MoV Ubukonje bukora Die Steel
Ibyuma bya Cr12MoV bikonje bikora bipfa gukorwa na Jinbaicheng biri mubyiciro byibyuma byangiza mikorobe yangiza ibyuma, birangwa no kwihanganira kwambara cyane, gukomera, guhindura mikorobe, guhagarara neza kwubushyuhe, imbaraga zunamye cyane, nibindi bintu.Nibya kabiri nyuma yicyuma cyihuta kandi ni ibikoresho byingenzi byo gushiraho kashe, umutwe ukonje, nibindi bikoresho.Cr12MoV ipfa ibyuma nicyuma cya karubone molybdenum ledeburite ibyuma birimo karubone nkeya kuruta ibyuma bya Crl2.Molybdenum na vanadium byongeweho kugirango bitezimbere imikorere ishyushye, ingaruka zikomeye no gukwirakwiza karbide yicyuma.Cr12MoV ipfa ibyuma bifite karubone nkeya kurenza Cr12 ipfa ibyuma.Kwiyongera kubintu bishya bivanze bitezimbere ibintu bya karbide itaringaniye.Byongeye kandi, molybdenum na molybdenum birashobora kugabanya gutandukanya karbide no kunoza ubukana.Vanadium na vanadium birashobora gutunganya ibinyampeke no kongera ubukana, Kubwibyo, ibyuma byububiko bwa Cr12MoV bya Jin Baicheng bifite ubukana bwinshi, hamwe nigice cyambukiranya munsi ya 400mm gishobora kuzimya burundu, kandi gishobora gukomeza gukomera no kwambara birwanya 300-400℃. Beside, Jinbaicheng ya Cr12MoV yibumba ifite ubukana bwiza kuruta ibindi bikoresho byo murwego rumwe kumasoko rusange, kandi amahirwe yo guhinduka kwijwi mugihe cyo kuzimya aragabanuka cyane.Kubwibyo, kwihanganira kwambara kwinshi hamwe nuburyo bwiza bwubukanishi butuma ibyuma bya Cr12MoV ya Jinbaicheng bikwiranye no gukora ibishushanyo bitandukanye bifite ibice binini byambukiranya ibice, imiterere igoye, kandi bikaba bihanganira ingaruka nini, hamwe nibikoresho bitandukanye byo guteramo ubukonje mu bihe bikomeye byakazi, nka gukubita bipfa, gutema bipfa, kuzunguruka bipfa, nibindi.
Ⅱ-Ubuyobozi bwo gusaba of Cr12MoV Ubukonje bukora Die Steel
①Cr12MoV irashobora gukoreshwa mugukora imiterere igoye ya convex, conave, no gushiramo blok zo gukubita ibishishwa hamwe nubunini bwibintu> 3mm.Birasabwa kugira ubukana bwa 58 ~ 62HRC mugihe ukora ibishushanyo mbonera na 60 ~ 64HRC mugihe ukora ibishushanyo mbonera.
②Kugirango habeho ibishishwa bya punch na conge bisaba kwihanganira kwambara cyane, birasabwa kugira ubukana bwa 60 ~ 62HRC mugihe ukora punch na 62 ~ 64HRC mugihe ukora ifumbire.
③Kugirango habeho kubyara ibishishwa bidashobora kwangirika mubishushanyo byimbitse, birasabwa kugira ubukana bwa 62 ~ 64HRC.
④Byakoreshejwe mugukora ibishushanyo mbonera, ibishushanyo mbonera, no gushiramo 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.
⑤Kugirango habeho kubyara ibicuruzwa bikonje bipfa kandi bipfa kubice bya aluminium, birasabwa kugira ubukana bwa 60-62HRC mugihe wapfuye, na 62-64HRC mugihe wapfuye.
⑥Birasabwa gukoresha ubukana bwa 62 ~ 64HRC kumurongo wa convex hamwe na convex ikoreshwa mugukora umuringa ukonje.
⑦Ibishishwa bya convex na conave bikoreshwa mubyuma bikonje bikonje birasabwa kugira ubukana bwa 62 ~ 64HRC.
⑧Isahani y'ibyuma ifite igice kinini cya 0,65% ~ 0,80% ikoreshwa mugukora karubone ifite ubukana bwa 37 ~ 42HRC, itanga igihe cyizuba kigera ku 150000.
⑨Isahani yicyuma ifite igice kinini cya 0,65% kugeza 0,80% ikoreshwa mugukora karubone ifite ubukana bwa 37-42HRC, kandi hamwe nubuvuzi bwa nitriding, ubuzima bwabo burashobora kugera kubihumbi 400000.
Ⅲ-Gutunganya of Cr12MoV Ubukonje bukora Urupfu:
Ibisobanuro byo koroshya imbeho ikonje: Kurinda no gushyushya ifu hamwe nibyuma byubushyuhe bwa 760-780℃kumasaha 10, hamwe no gukonjesha itanura hamwe nubukomezi bwa 196HBW.Gukonjesha ubukonje birashobora kugerwaho neza.
Ibisobanuro kuri isothermal spheroidizing annealing: 850-870℃ ×Amasaha 3-4, akonje mu ziko kugeza 740-760℃ ×Amasaha 4-5 yo kuvura isothermal, hamwe no gukonjesha ikirere≤241HBW, eutectic carbide urwego≤3, ubushyuhe bwiza bwa isothermal 740-76o℃, n'igihe≥Amasaha 4-5.
Ibisobanuro kuri spheroidizing annealing: (860± 10)℃ ×Amasaha 2-4, gukonjesha itanura ku gipimo cya 30℃/ isaha, (740± 10)° C x amasaha 4-6, gukonja buhoro kugeza 500-600℃hamwe nitanura, 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 bwubushyuhe 160-180, ubushyuhe bwamasaha 2, cyangwa ubushyuhe 325-375° C, ubushyuhe inshuro 2-3.
Kuzimya gake hamwe no kuzimya ubushyuhe buke: 950℃-1040℃ubushyuhe bukabije ni 200℃, ubushyuhe bwa kabiri.
Kuzimya cyane no kugaruka kwinshi ubushyuhe: 1050-1100℃, ubushyuhe bukabije ni 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 ultrafine irashobora guhinduka karbide nyuma ya 200℃ubushyuhe buke.Martensite itavuwe na kirogenike gusa igusha karbide nkeya mubice bimwe na bimwe nyuma yumuriro ukabije wubushyuhe.
Jinbaicheng yakoresheje uburyo bwo kuvura ubushyuhe buke bwo mu rwego rwo hejuru, bugumana ubukana bwinshi kandi bukarwanya 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 Jinbaicheng's Ibikoresho bya Cr12MoV bidafite ibyuma, nyuma yo kuvura nitrocarburizasi ya gaze, bigera ku bice birenga 30000, bikaba birenga inshuro 10 ugereranije n’ibibumbano bisa bivurwa no kuzimya bisanzwe no gushyuha.
