Ipayipi Lensimbi Elingenamthungo Elikhulu Lobubanzi

Ipayipi Lensimbi Elingenamthungo Elikhulu Elifakiwe Isithombe

Incazelo emfushane:

Ipayipi elikhulu lensimbi elingenamthungo eliwububanzi lisho ububanzi obungaphandle obungaphezu kuka-100MM futhi ukujiya kodonga kukhulu ngo-0.2 kunobubanzi obungaphandle bepayipi, ishubhu lensimbi elingenamthungo elingu-Large-diameter lenziwe ngeshubhu ingot eqinile noma i-capillary yokubhoboza, bese kuba ngokuginqika okushisayo nokugoqeka okubandayo. noma ukudayela okubandayo.

Isingeniso Somkhiqizo

Njengamanje ipayipi elikhulu lensimbi elingenamthungo laseChina, inqubo yokukhiqiza eyinhloko igoqelwe ngokushisa futhi inweba ukushisa kwepayipi lensimbi elingenamthungo elinobubanzi obukhulu, ukucaciswa kwepayipi elishisayo elinwetshiwe elingenamthungo lika-325mm-1220mm ubukhulu obukhulu obungu-120mm, lingakhiqiza ukunwetshwa okushisayo kwepayipi lensimbi engenamthungo. Izilinganiso ezijwayelekile ezingezona ezezwe lonke, ukunwetshwa okushisayo okungenamthungo yilokho esivame ukukusho ukuthi ukunwetshwa okushisayo, ukuminyana kuncane kodwa ukufinyela okuqinile kwensimbi egoqelwe ngendlela etshekile noma indlela yokudweba ukuze kwandiswe ukushoda kwezinqubo zokuqeda ipayipi lobubanzi bepayipi.Esikhathini esifushane sokuqina kwensimbi ukukhiqiza izinhlobo ezingezona ezijwayelekile nezikhethekile zamapayipi angenamthungo, kanye nezindleko eziphansi, ukusebenza kahle kokukhiqiza okuphezulu, umkhuba wokuthuthukiswa kwamasimu okugingqika emhlabeni wonke namuhla.

Ipayipi elikhulu lensimbi elingenamthungo elikhulu ngomdwebo obandayo, imikhiqizo yensimbi egoqelwe ngokubanda, njengokwakheka okubandayo, ukwelashwa ngokushisa futhi ngaphandle kokulethwa okuqondile kwesimo okubizwa ngokuthi isimo esidonswa ngokubanda noma esigoqeka ngokubanda.Uma kuqhathaniswa nesimo esigoqekayo (sokubumba), isimo sensimbi (egoqiwe) enembayo enobukhulu obuphezulu, ikhwalithi enhle yendawo engaphezulu, ubuhwaqaqe obuphansi, kanye nezakhiwo eziphakeme zokusebenza, ngenxa yokudonswa kwensimbi edonswayo (egoqiwe) engaphezulu kwesimo se-oxide. ayimboziwe, futhi kunengcindezi enkulu, esengozini yokugqwala noma ukugqwala, futhi ngaleyo ndlela isimo sensimbi esidonswayo (esigingqiwe), ukupakishwa kwayo, izidingo zesitoreji ziqine kakhulu, ngokuvamile zidinga ukugcinwa endaweni yokugcina izinto, futhi kufanele sinake. isikhwama sokulawula izinga lokushisa nomswakama.

Insimbi Engenamthungo Enkulu Yobubanzi 1

I-Hot Rolling (Forging)

Insimbi engenamthungo enkulu enobubanzi obuyindilinga ngemva kokuginqika okushisayo noma ukwenza ukwelashwa okukhethekile kokushisa futhi akusekho ukulethwa okuqondile Ngemva kokupholisa, isimo sibizwa ngokuthi i-hot rolling noma i-forging, izinga lokushisa eligoqiwe elishisayo (okwenziwe) ngokuvamile lingama-800 ~ 900 ℃, Ngemva kwemvelo evamile. ukupholisa emoyeni, isimo sokuginqika esishisayo (sokubumba) esilingana nokujwayelekile.Umehluko ungenxa yokushiswa (ukubumba) ukuqedwa kwamazinga okushisa aphezulu naphansi, ngokungafani nokulawula ukushisa okuqinile okuqinile futhi ngaleyo ndlela ukuguquguquka kwesakhiwo esincane sensimbi kanye nezakhiwo zemishini kunalokho okwenziwe kahle.Njengamanje izinkampani eziningi zensimbi zilawulwa ukugoqa, ngenxa yokuthi ukulawulwa kokushisa kokuphothula kuqinile kakhulu, futhi ngemva kokuqeda izinyathelo zokupholisa eziphoqelelwe ezithathwe ngaleyo ndlela ukucwenga okusanhlamvu kwensimbi, ukulethwa kwensimbi kunezindawo eziphezulu zemishini.Akukho ukupholisa okulawulwa kwe-Twist kwentambo yocingo olushisayo olungaphezu kokusebenza kwenduku evamile egoqwe ngocingo olushisayo kuyiqiniso, isimo sokulethwa kwensimbi esigoqiwe esishisayo, indawo engaphezulu imbozwe ungqimba lwe-iron oxide, enesimo esithile. izinga lokumelana nokugqwala, ukugcinwa kwesitoreji Ngokungafani nezidingo eziqinile zesimo esidonswayo (esigoqiwe) sokulethwa kwensimbi, insimbi enosayizi omaphakathi, ipuleti lensimbi eliwugqinsi lingagcinwa egcekeni elivulekile noma ngekhava yotshani.Ifekthri enkulu yensimbi engenamthungo enobukhulu ngaphambi kokwelashwa kokushisa kwe-anneal, lesi simo sibizwa ngokuthi isimo sokulethwa kwe-annealing.I-Annealing inhloso eyinhloko ukuqeda amaphutha kanye nokwenza ngcono inhlangano nokucindezeleka kwangaphakathi okusele ngaphambi kwenqubo nangemuva kwenqubo yokulungiselela inhlangano nokusebenza, i-alloy structural steel, ukuqina okuqinisekisiwe kwensimbi yesakhiwo, insimbi ekhanda ebandayo, insimbi enensimbi evame ukusetshenziswa. insimbi yensimbi, i-turbine blade steel, ukulethwa kwekhebula lomzimba lensimbi engagqwali elingashi.

Isicelo

Nakuba intengo yepayipi elikhulu elingenamthungo ingaphezudlwana kwepayipi elingenamthungo elishiselwe, ukusebenza kwalo okuthuthukisiwe nezinzuzo kuyenza ifanelekele noma yisiphi isicelo.Ukubaluleka kwamapayipi amakhulu angenazihibe kuyakhula ekusetshenzisweni kwezentengiselwano kwamapayipi, okuhlanganisa amapayipi, izinsimbi zikawoyela, ukwakha imikhumbi, izinsimbi zasogwini lolwandle, izingxenye zemishini, imikhumbi yokucindezela, izingxenye zemishini, kanye nempahla yendawo kawoyela.
