Ⅰ-KuyiniI-Cr12MoV Cold Working Die Steel
I-Cr12MoV i-cold working die steel ekhiqizwa ngu-Jinbaicheng iyingxenye yensimbi yensimbi engagugi kakhulu, ebonakala ngokumelana nokugqokwa okuphezulu, ukuqina, ukuwohloka okuncane, ukuzinza okuphezulu kwe-thermal, amandla okugoba okuphezulu, nezinye izakhiwo. Ingokwesibili ngemva kwensimbi enesivinini esikhulu futhi iyimpahla ebalulekile yokugxiviza, isihloko esibandayo, nezinye izinto. I-Cr12MoV die steel iyinsimbi ye-carbon molybdenum ledeburite enokuqukethwe kwekhabhoni ephansi kunensimbi ye-Crl2. I-Molybdenum ne-vanadium yengezwa ukuze kuthuthukiswe ukusebenza okushisayo, ukuqina komthelela kanye nokusatshalaliswa kwe-carbide yensimbi. I-Cr12MoV die steel inokuqukethwe kwekhabhoni ephansi kune-Cr12 die steel. Ukwengezwa kwezinto ezintsha ze-alloy kuthuthukisa ukwenzeka kwe-carbide engalingani. Ngaphezu kwalokho, i-molybdenum ne-molybdenum inganciphisa ukuhlukaniswa kwe-carbide futhi ithuthukise ukuqina. I-Vanadium ne-vanadium ingacwenga okusanhlamvu futhi ikhulise ukuqina, Ngakho-ke, insimbi yokubumba i-Cr12MoV kaJin Baicheng inokuqina okuphezulu, enesiqephu esingaphansi kwama-400mm esingacinywa ngokuphelele, futhi isengakwazi ukugcina ubulukhuni obuhle nokumelana nokugqoka ku-300-400.℃. Besides, Insimbi yokubumba ye-Jinbaicheng ye-Cr12MoV inokuqina okungcono kunezinye izinto zebanga elifanayo emakethe evamile, futhi amathuba okushintsha umthamo ngesikhathi sokucisha ancipha kakhulu. Ngakho-ke, ukumelana kwayo nokugqokwa okuphezulu kanye nezakhiwo ezinhle ezibanzi zemishini kwenza insimbi yokubumba i-Cr12MoV ka-Jinbaicheng ifaneleke kakhulu ukukhiqiza isikhunta esihlukahlukene esinezingxenye ezinkulu eziphambanayo, ukwakheka okuyinkimbinkimbi, nokumelana nemithelela emikhulu, kanye namathuluzi ahlukahlukene okunyathela abandayo ngaphansi kwezimo ezinzima zokusebenza, njenge ukubhoboza kuyafa, ukusika kuyafa, ukugoqa kuyafa, njll. Umdwebo ojulile wepuleti lensimbi, isaha esiyindilinga, amathuluzi ajwayelekile namathuluzi okulinganisa, intambo yokugoqa, njll.
Ⅱ-Isiqondiso sohlelo lokusebenza of I-Cr12MoV Cold Working Die Steel
①I-Cr12MoV ingasetshenziswa ukwenza izimo eziyinkimbinkimbi ze-convex, i-concave, futhi ifake amabhulokhi wokubhoboza izibungu ezinogqinsi lwezinto>3mm. Kutuswa ukuthi kube nobulukhuni obungu-58~62HRC lapho kwenziwa isikhunta esiyi-convex kanye no-60~64HRC uma kwenziwa izibunzi ezikhongolose.
②Ukuze kukhiqizwe isikhunta se-punch kanye ne-concave esidinga ukumelana nokugqoka okuphezulu, kunconywa ukuthi kube nobulukhuni be-60 ~ 62HRC lapho wenza i-punch kanye ne-62 ~ 64HRC uma wenza isikhunta se-concave.
③Ukuze kukhiqizwe isikhunta se-concave esingagugi ekubunjweni kokudweba okujulile, kunconywa ukuthi kube nobulukhuni obungu-62~64HRC.
④Isetshenziselwa ukukhiqiza isikhunta esiyi-convex, isikhunta esigobile, kanye nokufaka amabhlogo adinga ukumelana nokugqokwa okuphezulu kanye nokwakheka okuyinkimbinkimbi ekubunjweni okugoba. Kunconywa ukuthi ube nobulukhuni obuyi-60-64HRC lapho wenza isikhunta se-convex, kanye ne-60-64HRC uma wenza isikhunta se-concave.
⑤Ukuze kukhiqizwe i-extrusion ebandayo iyafa futhi ishone ezingxenyeni ze-aluminium, kunconywa ukuthi kube nobulukhuni obuyi-60-62HRC lapho kwenziwa i-dies, kanye ne-62-64HRC lapho kwenziwa ukufa.
⑥Kunconywa ukusebenzisa ubulukhuni obungu-62~64HRC ekubunjweni kwe-convex kanye ne-concave okusetshenziselwa ukwenza isikhunta se-copper extrusion extrusion.
⑦Ukubunjwa kwe-convex kanye ne-concave okusetshenziselwa isikhunta sensimbi esibandayo se-extrusion kuyanconywa ukuthi sibe nobulukhuni obungu-62~64HRC.
⑧Amapuleti ensimbi asentwasahlobo anengxenye enkulu engu-0.65%~0.80% asetshenziselwa ukwakha ikhabhoni anobunzima obungu-37~42HRC, ahlinzeka ukuphila okufika kwemijikelezo engu-150000.
⑨Amapuleti ensimbi asentwasahlobo anengxenye enkulu engu-0.65% kuya ku-0.80% asetshenziselwa ukwakha ikhabhoni anobunzima obungu-37-42HRC, futhi ngokwelashwa okwengeziwe kwe-nitriding, impilo yabo yesevisi ingafinyelela izikhathi ezingu-400000.
Ⅲ-Iyacubungula of I-Cr12MoV Cold Working Die Steel:
Ukucaciswa kokuthambisa isikhunta esibandayo se-extrusion: Vikela futhi ushise isikhunta ngamafayili ensimbi ekushiseni kuka-760-780.℃amahora angu-10, ngokupholisa isithando somlilo kanye nokuqina kwe-196HBW. Ukwakhiwa kwe-cold extrusion kungafinyelelwa ngokushelela.
Ukucaciswa kwe-annealing ye-isothermal spheroidizing: 850-870℃ ×Amahora angu-3-4, epholile esithandweni ukuya ku-740-760℃ ×Amahora angu-4-5 wokwelashwa kwe-isothermal, ngobulukhuni bokupholisa umoya≤241HBW, i-eutectic carbide grade≤3, izinga lokushisa elilungile le-isothermal 740-76o℃, kanye nesikhathi≥4-5 amahora.
Ukucaciswa kwe-spheroidizing annealing: (860± 10)℃ ×Amahora angu-2-4, ukupholisa isithando somlilo ngenani lokupholisa lama-30℃ngehora, (740± 10)° C x amahora angu-4-6, ukupholisa kancane ku-500-600℃ngesithando somlilo, ukupholisa umoya ngemva kokukhishwa, ubulukhuni 207-255HBW.
Ukucaciswa okujwayelekile kokucisha kanye nokushisa: izinga lokushisa lokucisha i-1000-1050℃, ukucisha amafutha noma ukucisha, ubulukhuni 260HRC, izinga lokushisa lokushisa 160-180, isikhathi sokushisa amahora angu-2, noma izinga lokushisa lokushisa 325-375° C, ukushisa izikhathi ezingu-2-3.
Ukucisha okuphansi kanye nezinga lokushisa lokucisha eliphansi lokubuya: 950℃-1040℃, izinga lokushisa lokushisa lizungeze ama-200℃, ukufudumala kwesibili.
Ukushisa okuphezulu kokucima kanye nokubuya okuphezulu kokucisha: 1050-1100℃, izinga lokushisa lokushisa lizungeze ama-520℃, ukufudumala kwesibili. Indlela yesibili yokuqina esetshenziselwa ukucisha okuphezulu nokugaywa kabusha okuphezulu ithuthukisa ubulukhuni, kodwa okusanhlamvu kuzokhula.
Ukwelashwa kwe-Cryogenic: Insimbi ye-Cr12MoV ithola ukwelashwa kwe-cryogenic, okunganciphisa ama-ultrafine carbides ahlakazeke kakhulu asuka ku-martensite ecishiwe, bese lawa ma-carbides e-ultrafine angaguqulwa abe ama-carbides ngemuva kuka-200.℃izinga lokushisa eliphansi. I-martensite ngaphandle kokwelashwa kwe-cryogenic idonsa kuphela inani elincane le-carbide kwezinye izindawo zendawo ngemva komlilo ophansi we-circumferential.
I-Jinbaicheng isebenzisa indlela yokwelapha ukushisa kwamakhemikhali okunezinga lokushisa eliphansi, egcina ubulukhuni obuphezulu nokumelana nokugqoka kwensimbi ye-Cr12MoV. Izendlalelo ezintathu ezivame ukusetshenziswa ezisetshenziselwa ukushisa kwamakhemikhali okushisa aphansi, okuyi-ion nitriding, i-gas nitrocarburizing, nebhavu lokugeza usawoti esibabule i-cyanide co nitriding, zinomthelela omkhulu wokungaguquguquki nokunamathela, okugeza usawoti esibabule i-cyanide co nitriding ehamba phambili.
Impilo yesevisi yomdwebo iyafa ku-Jinbaicheng's Izitsha ze-Cr12MoV zensimbi engagqwali, ngemva kokwelashwa kwe-nitrocarburization yegesi, zifinyelela ngaphezu kwezingcezu ezingu-30000, ezinde izikhathi ezingaphezu kwezingu-10 kunezibunjwa ezifanayo eziphathwa ngokucisha nokushisa okuvamile.
