Ipayipi lensimbi elingenamthungo isipayipi lensimbi elenziwe ngensimbi eyindilinga ephelele engenawo umthungo oshiselwe ngaphezulu.
Ukwahlukanisa: Ngokusho kokuma kwesigaba, ipayipi lensimbi engenamthungo lihlukaniswe ngezinhlobo ezimbili: nxazonke futhi ezimise.
Ububanzi bodongaUbubanzi: 0.25-200 mm.
Ibanga lobubanziUbubanzi: 4-900 mm.
Inqubo yokukhiqiza: Ukukhiqizwa kwepayipi lensimbi engenamthungo ngokuyinhloko kusebenzisa indlela yokudweba eshisayo noma ebandayo.
Izinzuzo: amandla okucindezela angcono, ukwakheka okufanayo okufanayo, amandla aphezulu, nokujikeleza okungcono.
Ukubi: izindleko eziphezulu nezinketho zosayizi olinganiselwe
Isebenzisa: Isetshenziswa kakhulu njengepayipi le-petroleum geological drilling, ipayipi le-petrochemical cracking, ipayipi likabhayela, ipayipi elithwalayo, kanye nepayipi lensimbi elinembayo eliphezulu lemoto, ugandaganda, kanye nendiza.
Izinkinobho Zokuzulazula
inqubo yokukhiqiza ye-hot rolling
Ukulungiswa kwempahla eluhlaza→Ukushisa→Ukubhoboza→Ukugoqeka→Ukunwebeka→Ukwehliswa kosayizi nodonga→Ukwelashwa kokushisa→Ukulungisa ukuqina→Ukuhlola nokuhlola→Ukusika nokuqeda Ukuhlola Umkhiqizo→Ukwelashwa kokunqanda ukubola
Ukulungiselela impahla eluhlaza: Amabhilidi adinga ukuhlanzwa ukuze kukhishwe noma imaphi ama-oxide noma okunye ukungcola ngaphambi kokukhiqizwa.
Ukushisisa: I-billet ifakwa esithandweni sokushisa ukuze sishiswe ekushiseni okufanelekile, okuvame ukuba ngaphezu kuka-1200 ℃.
Ukubhobozwa: I-billet eshisayo ifakwa emshinini wokubhoboza, owubhoboza ukuze wenze i-billet engenalutho.
Ukuginqika: Ngemva kokubhoboza, i-billet ingena emshinini wokugaya.I-billet idlula kumapheya amaningi amaroli anciphisa ngokuqhubekayo ububanzi bangaphandle futhi andise ubude be-billet.
Ukwelula: I-billet iphinde yelulwe kusetshenziswa i-elongator ukuze kuzuzwe ukucaciswa kobukhulu obunembe kakhudlwana.
Ukuncishiswa kosayizi nodonga: Ukulinganisa nokunciphisa udonga lwe-billet emshinini wokulinganisa ukuze kuzuzwe ubukhulu obuqondile bokugcina nobukhulu bodonga.
Ukwelashwa kokushisa: ipayipi idinga ukwelashwa kokushisa ukuze ilungise inhlangano yayo yensimbi futhi ithuthukise izakhiwo zemishini yezinto ezibonakalayo, kuhlanganise nezinqubo ezijwayelekile kanye ne-annealing.
Ukulungiswa kokuqina: Ipayipi ilungiswa ngomshini wokuqondisa ukuze kuqinisekiswe ukuqondisa kwepayipi.
Ukuhlola nokuhlola: Ukuhlolwa nokuhlolwa okuhlukahlukene kwenziwa epayipini lensimbi eligcwalisiwe elingenamthungo, njenge-hydrotest, ukuhlolwa kwe-ultrasonic, ukuhlolwa kwamanje kwe-eddy, njll.
Ukusika nokuqeda Ukuhlolwa Komkhiqizo: Sika amashubhu abe ngobude obucacisiwe ngokwezidingo zekhasimende futhi wenze ukuhlola kokugcina okubonakalayo nokwezinhlangothi.
Ukwelashwa kwe-anti-corrosion: Uma kunesidingo, ipayipi lensimbi elingenamthungo ligcotshwa ngamafutha anqanda ukugqwala noma ezinye izindlela zokwelapha zokunqanda ukugqwala, njengamagalanithi;3LPE, FBE nokunye.
Inqubo yokukhiqiza ye-cold-drawn
Ukulungiswa kwepayipi lebillet→Ukwelashwa kokuthunga →Ukugquma nokugcobisa→Ukudweba Okubandayo→Ukwelashwa kokushisa→Ukulungisa ubuqotho→Ukuhlola nokuhlola→Ukusika nokuqeda Ukuhlolwa Komkhiqizo→Ukwelashwa kokunqanda ukubola
Ukulungiswa kwepayipi le-billet: Ukukhethwa kwepayipi lensimbi elingenamthungo elifanele elishisayo eligoqiwe njengempahla eluhlaza, okungukuthi ipayipi lokuqala le-billet.
Ukwelashwa kwe-anealing: Ukuze kuqedwe ukucindezeleka okukhiqizwa phakathi nenqubo yokugoqa okushisayo kwamapayipi e-billet, amapayipi e-billet ngokuvamile adinga ukudonswa.
I-Pickling kanye Nokugcoba: Ngemuva kokufakwa kwe-anneal, amashubhu adinga ukucwiliswa ukuze kukhishwe isikhumba esine-oxidized kanye nokugqwala.Ngemva kwalokho, into yokugcoba isetshenziswa endaweni yeshubhu ukuze kuncishiswe ukungqubuzana nokuguga ngesikhathi somdwebo obandayo.
Umdwebo Obandayo: Ipayipi ye-billet ifakwe emshinini wokudweba obandayo futhi yelulwe ngokusebenzisa i-die, inqubo enciphisa ububanzi bepayipi kanye nokuthuthukisa ukuphela kwendawo kanye nokunemba kobukhulu.
Ngemuva kwalokho, ukwelashwa kokushisa nezinye izinqubo zokukhiqiza zifana nokugoqa okushisayo, futhi ngeke kuphindwe lapha.
Ungahlukanisa kanjani ipayipi lensimbi eligoqiwe nelibandayo elidonswayo, ungagxila kulezi zici ezilandelayo:
| Uhlu | hot rolling | umdwebo obandayo |
| Ukubukeka | Ingaphezulu liqinile futhi lingase libe nesikhumba esine-oxidized kanye nokukhubazeka okwengeziwe njengokuklwebheka, ama-pockmark, nama-rolling indent | Isiphetho esihle esingaphezulu, ngokuvamile sishelela futhi sikhanya kunepayipi lensimbi eligoqiwe elishisayo |
| Ububanzi Bangaphandle(OD) | OD≥33.9 | OD＜33.9 |
| Ukuqina Kwezindonga | 2.5-200mm | 0.25-12mm |
| Ukubekezelelana | Ithambekele ekuqineni kodonga olungalingani kanye ne-ovalization | Ubukhulu bodonga obufana nobubanzi obungaphandle obunokubekezelelana okuncane |
| Amanani | Intengo ephansi yezimo ezifanayo | Intengo ephezulu yezimo ezifanayo |
