Ipayipi lensimbi elingenamthungo elidonswa ngokubandayin aipayipi lensimbi elingenamthungo elidonswa ngamakhazangokunemba okuphezulu kwe-dimensional kanye nokuqeda okuhle kwendawo yokwakheka kwemishini kanye nemishini ye-hydraulic.Ukukhetha ipayipi lensimbi elingenamthungo elinembileukwenza ukwakheka kwemishini noma okokusebenza okunamanzi kungasindisa kakhulu isikhathi somshini, kuthuthukise izinga lokusebenzisa izinto futhi kuthuthukise ikhwalithi yomkhiqizo.
Ukuze uthole amapayipi ensimbi angenamthungo anosayizi omncane kanye nekhwalithi engcono, ukugoqa okubandayo, umdwebo obandayo noma zombili izindlela kufanele zamukelwe.Ukugoqa okubandayo kuvame ukwenziwa emshinini wokugaya ophakeme kabili, futhi amapayipi ensimbi angenamthungo agoqelwa ku-annular pass eyakhiwe yi-variable cross-section circular groove kanye nepulaki ye-conical engashintshi.Umdwebo obandayo uvame ukwenziwa ngo-0.5~100T we-single-chain noma umshini wokudweba we-double-chain obandayo.
2. Ipayipi lensimbi engenamthungo elidonswa kubanda liwumkhiqizo ovele eminyakeni yamuva, ikakhulukazi ngenxa yokuthi imbobo yangaphakathi kanye nobukhulu bodonga lwangaphandle banokubekezelelana okuqinile kanye nobulukhuni.
Izici zeipayipi lensimbi elidonswa ngokubanda (eligingqelwe) elingenamthungo:
1. Ububanzi obuncane obungaphandle.2. Ukunemba okuphezulu kungasetshenziselwa ukukhiqizwa kwenqwaba encane 3. Ukunemba okuphezulu kwemikhiqizo ebandayo edonswe (egoqiwe) kanye nekhwalithi enhle yendawo.4. Indawo yesiphambano sepayipi yensimbi engenamthungo iyinkimbinkimbi kakhulu.5. Ukusebenza kwepayipi lensimbi engenamthungo kuphakeme, futhi insimbi iminyene.Amapayipi ensimbi angenamthungo wezakhiwo(GB/T8162-2008) amapayipi ensimbi angenamthungo wezakhiwo ezijwayelekile kanye nezakhiwo zemishini.Kuwuhlobo lwepayipi lensimbi elingenamthungo elihlukaniswa ngokusetshenziswa kwalo okuhlukene.Ububanzi bokusetshenziswa buhlanganisa zonke izinhlobo zamapayipi ensimbi angenamthungo asetshenziswa ezakhiweni ezijwayelekile kanye nezakhiwo zemishini, kanye nenani elikhulu lezimboni ezifana nezokwakha, imishini, ezokuthutha, izindiza, ukuxhashazwa kukawoyela, njll.
Umehluko omkhulu phakathi kwe-annealing kanye nokujwayelekile:
1. Izinga lokupholisa le-normalization lishesha kancane kune-annealing, futhi izinga le-supercooling liphakeme 2. I-microstructure etholwe ngemva kokujwayelekile ihle kakhulu, futhi amandla nobulukhuni buphakeme kunobu-annealing.
Ukukhethwa kwe-annealing kanye nokujwayelekile:
1. Ukulinganisa kuvame ukusetshenziswa esikhundleni sokudonsa amapayipi ensimbi engenamthungo enekhabhoni ephansi anokuqukethwe kwekhabhoni ngaphansi kuka-0.25%.ngoba
Ukuze uthole izinga lokupholisa elisheshayo, lingavimbela ipayipi lensimbi engenamthungo enekhabhoni ephansi ukuthi lingahlukaniseki eduze komngcele wokusanhlamvu futhi lifuduke izikhathi ezintathu ze-carburization Ukuze kuthuthukiswe ukusebenza kokuguqulwa okubandayo kwezingxenye zokunyathela;Ukuzijwayeza kungathuthukisa ubulukhuni bensimbi
Ukukwazi ukusebenzisa ipayipi lensimbi engenamthungo;Uma ingekho enye inqubo yokwelapha ukushisa, i-normalizing can Ukucwenga okusanhlamvu futhi uthuthukise amandla epayipi lensimbi elingenasikhabhoni elingenamthungo.
2.Ipayipi lensimbi engenamthungo elikhabhoni elikhabhoni elimaphakathingokuqukethwe kwekhabhoni phakathi kuka-0.25 no-0.5% nakho kungashintshwa ngokujwayelekile
Faka esikhundleni i-annealing, nakuba ubulukhuni bepayipi lensimbi elidonswa ngokubanda elingenamthungo lensimbi ye-carbon steel eduze nomkhawulo ongaphezulu wokuqukethwe kwekhabhoni buphakeme kancane ngemva kokujwayelekile Iphakeme, kodwa isenganqunywa, futhi izindleko zokujwayelekile ziphansi futhi umkhiqizo uphezulu. .3.Ipayipi lensimbi elidonswa ngokubanda elingenamthungo elinekhabhoni ephakathi kuka-0.5 no-0.75% linokuqukethwe kwekhabhoni ephezulu,
Ukuqina ngemuva kokujwayelekile kuphakeme kakhulu kunokwehliswa, ngakho-ke kunzima ukwenza ukusika, ngakho-ke ngokuvamile Sebenzisa i-annealing ephelele ukuze unciphise ubulukhuni futhi uthuthukise ukusebenza kahle.
4. Ikhabhoni ephezulu noma insimbi yamathuluzi enokuqukethwe kwekhabhoni ＞ 0.75% wepayipi lensimbi engenamthungo elidonswa ngokubanda ngokuvamile lithatha ibhola Ukuhushula ngamakhemikhali kusetshenziswa njengendlela yokwelapha yokushisa yokuqala.Uma kukhona inethiwekhi yesibili usimende, kufanele kwenziwe kuqala ukuqeda Fire.I-Annealing iwukushisa ipayipi lensimbi engenamthungo elidonsa ukubanda libe ezingeni lokushisa elifanele futhi uligcine isikhathi esithile,Inqubo yokwelapha ukushisa ngokupholisa kancane.Ukupholisa kancane kuyisici esiyinhloko sokuhoxisa, futhi ukudweba nokudonsa okubandayo akukhona Ngokuvamile, ipayipi lensimbi lomthungo lipholiswa libe ngaphansi kuka-550 ℃ esithandweni.I-Annealing isetshenziswa kabanzi Ukwelashwa kokushisa okubanzi kuvame ukusetshenziswa njengokulungiselela ekukhiqizeni izingxenye zamathuluzi noma zemishini Ukwelashwa kokushisa kuhlelwa ngemva kokuphonswa, ukubumba nokushisela nangaphambi kokusika (okubi) ukuze kuqedwe inqubo yangaphambilini.Okunye ukukhubazeka okubangelwa inqubo. , futhi ulungiselele inqubo elandelayo.
Inhloso yokuhlanganisa: ① ukunciphisa ubulukhuni bepayipi lensimbi engenamthungo elidonswa ngokubanda ukuze kube lula ukwenziwa komshini;② Qeda izinhlobo ezahlukene Ukucindezeleka ukuvimbela ukuwohloka kwepayipi lensimbi engenamthungo elidonswa kubanda;③ Yenza ngcono okusanhlamvu okumahhadla futhi uthuthukise ukwakheka kwangaphakathi Lungiselela ukwelashwa kokushisa kokugcina.
