Ukuchezuka kwamapayipi ensimbi anobubanzi obukhulu ekukhiqizeni: Ububanzi obujwayelekile bepayipi lensimbi enobubanzi obukhulu: ububanzi obungaphandle: 114mm-1440mm ukujiya kodonga: 4mm-30mm. Ubude: bungenziwa bube ubude obunqunyiwe noma ubude obungagxilile ngokuya ngezidingo zekhasimende. Amapayipi ensimbi anobubanzi obukhulu asetshenziswa kakhulu emikhakheni ehlukahlukene yezimboni njengendiza, i-aerospace, amandla, i-electronics, izimoto, imboni yokukhanya, njll., futhi ingenye yezinqubo ezibalulekile zokushisela.

Izindlela zokucubungula eziyinhloko zamapayipi ensimbi anobubanzi obukhulu yilezi: Insimbi yokufaka: indlela yokucubungula ingcindezi esebenzisa amandla aphindaphindayo wesando esakhayo noma ingcindezi yomshini wokunyathelisa ukuze uguqule i-billet ibe yisimo nosayizi esiwudingayo. I-Extrusion: Kuyindlela yokucubungula lapho insimbi ifaka khona insimbi kusilinda esivaliwe sokukhipha, ifake ingcindezi ekugcineni, bese icindezela insimbi iphume embotsheni yokufa ecacisiwe ukuze ithole umkhiqizo osuphelile onomumo nosayizi ofanayo. Isetshenziswa kakhulu ekukhiqizeni insimbi yensimbi engeyona ayoni. I-Rolling: Indlela yokucubungula ingcindezi lapho i-billet yensimbi yensimbi idlula igebe (izinhlobo ezihlukahlukene) zama-roller ajikelezayo, futhi ingxenye yesiphambano yezinto ezibonakalayo iyancishiswa futhi ubude buyanda ngenxa yokucindezelwa kwama-roller. Insimbi yokudweba: Kuyindlela yokucubungula edonsa i-billet yensimbi egoqiwe (iphrofayili, ishubhu, umkhiqizo, njll.) ngembobo yokufa ukuze kuncishiswe isigaba esiphambanayo nokwandisa ubude. Isetshenziselwa kakhulu ukucubungula okubandayo.

Amapayipi ensimbi anobubanzi obukhulu aqedwa ngokuyinhloko ngokunciphisa ukungezwani nokugoqeka okuqhubekayo kwezinto eziyisisekelo ezingenalutho ngaphandle kwama-mandrels. Ngaphansi kwesisekelo sokuqinisekisa ipayipi lensimbi elivunguzayo, ipayipi lensimbi elivunguzayo lishisiswe libe kuzinga lokushisa eliphakeme elingaphezu kuka-950℃ lilonke bese ligingqwa libe ngamapayipi ensimbi angenamthungo anezincazelo ezihlukahlukene ngokusebenzisa isigayo sokunciphisa ukungezwani. Umbhalo ojwayelekile wokukhiqizwa kwamapayipi ensimbi anobubanzi obukhulu ukhombisa ukuthi ukuchezuka kuvunyelwe ekwenziweni kwamapayipi ensimbi anobubanzi obukhulu: Ubude bokuchezuka okuvumelekile: Ubude bokuchezuka okuvumelekile kwebha yensimbi uma ilethwa ngobude obumisiwe akumele kudlule + 50mm. I-Curvature kanye nokuphela: Ukuguqulwa kokugoba kwemigoqo yensimbi eqondile akufanele kuthinte ukusetshenziswa okuvamile, futhi ukugoba okuphelele akufanele kudlule i-40% yobude obuphelele bebha yensimbi; imiphetho yensimbi kufanele igundwe iqonde, futhi ukuguqulwa kwendawo akufanele kuthinte ukusetshenziswa. Ubude: Izinsimbi zensimbi ngokuvamile zilethwa ngobude obunqunyiwe, futhi ubude obuthile bokulethwa kufanele buboniswe kunkontileka; lapho izinsimbi zensimbi zilethwa ngamakhoyili, ikhoyili ngayinye kufanele ibe yinsimbi, futhi u-5% wamakhoyili eqoqweni ngalinye avunyelwe ukuba abe nezinsimbi ezimbili. Isisindo sekhoyili kanye nedayamitha yekhoyili kunqunywa ngokuxoxisana phakathi kwezinkampani ezinikezelayo nezifunayo.

Izindlela zokwenza amapayipi ensimbi anobubanzi obukhulu:
1. Indlela yokwandisa i-push push: Imishini yokwandisa i-push ilula, inezindleko eziphansi, kulula ukuyinakekela, iyonga, futhi ihlala isikhathi eside, futhi imininingwane yomkhiqizo ingashintshwa kalula. Uma udinga ukulungisa amapayipi ensimbi anobubanzi obukhulu neminye imikhiqizo efanayo, udinga kuphela ukwengeza izesekeli ezithile. Ilungele ukukhiqizwa kwamapayipi ensimbi anobubanzi obuncane obuncane naphakathi nendawo, futhi ingakhiqiza namapayipi anezindonga eziwugqinsi angeqi umthamo wezinto zokusebenza.
2. Indlela ye-extrusion eshisayo: Okungenalutho kudinga umshini ngaphambi kokukhipha. Lapho ukhipha amapayipi anobubanzi obungaphansi kuka-100mm, ukutshalwa kwezimali kwemishini kuncane, imfucuza yezinto ezibonakalayo incane, futhi ubuchwepheshe buvuthiwe. Kodwa-ke, uma ububanzi bepayipi bukhula, indlela yokushisa eshisayo idinga i-tonnage enkulu kanye nemishini yamandla aphezulu, futhi uhlelo lokulawula oluhambisanayo kufanele luthuthukiswe.
3. Indlela yokubhoboza okushisayo: Ukubhoboza okushisayo ikakhulukazi ukunwetshwa kwe-longitudinal rolling kanye nesandiso sokugoqa esitshekile. Isandiso se-longitudinal rolling ikakhulukazi sihlanganisa ukugingqika okuqhubekayo kwe-mandrel ekhawulelwe, ukugingqika okuqhubekayo kwe-mandrel okulinganiselwe, ukugingqika okuqhubekayo kwama-mandrel amathathu-roller okulinganiselwe, kanye nokugingqika okuqhubekayo kwe-mandrel entantayo. Lezi zindlela zinokukhiqiza okuphezulu, ukusetshenziswa kwensimbi okuphansi, imikhiqizo emihle, nezinhlelo zokulawula, futhi ziyasetshenziswa kabanzi.

Amapharamitha afanelekile okuthola iphutha lamapayipi ensimbi anobubanzi obukhulu:
Ekukhiqizeni amapayipi ensimbi anobubanzi obukhulu, ama-inclusions ayindilinga eyodwa kanye nama-pores ane-diameter ye-weld engadluli ku-3.0mm noma i-T/3 (T iwugqinsi olucacisiwe lwamapayipi ensimbi) afanelekile, noma yikuphi okuncane. Ngaphakathi kwanoma yiluphi uhla lwe-weld oluyi-150mm noma 12T (kungakhathaliseki ukuthi luncane kangakanani), lapho isikhawu phakathi kokufakwa okukodwa kanye nembobo singaphansi kuka-4T, isamba samadiayimitha azo zonke izinkinga ezingenhla ezivunyelwe ukuba khona ngokuhlukana akufanele zidlule u-6.0mm. noma 0.5T (noma yikuphi okuncane). Ukufakwa komugqa owodwa okunobude obungeqile ku-12.0mm noma T (noma yikuphi okuncane) nobubanzi obungeqile ku-1.5mm kuyafaneleka. Ngaphakathi kwanoma iyiphi i-weld engu-150mm noma engu-12T ubude (noma yikuphi okuncane), lapho isikhala phakathi kokufakwa ngakunye singaphansi kuka-4T, ubude obuqoqiwe obukhulu bazo zonke izinkinga ezingenhla ezivunyelwe ukuba zibe khona ngokuhlukana akumele zidlule u-12.0mm. Unqenqema lokuluma olulodwa lwanoma ibuphi ubude olunomkhawulo wokujula okungu-0.4mm lufanelekile. Unqenqema lokuluma olulodwa olunobude obukhulu obungu-T/2, ukujula okuphezulu okungu-0.5mm futhi okungadluli ku-10% wogqinsi olushiwo odongeni lufanelekile inqobo nje uma kungekho mikhawulo yokuluma engaphezu kwamabili phakathi kwanoma yibuphi ubude be-weld obungama-300mm. Yonke imiphetho enjalo yokuluma kufanele igaywe. Noma iyiphi i-bite edge edlula ububanzi obungenhla kufanele ilungiswe, indawo eyinkinga kufanele inqunywe, noma lonke ipayipi lensimbi kufanele lenqatshwe. Ukulunywa kwanoma ibuphi ubude nokujula okudlulanayo ohlangothini olufanayo lwe-weld yangaphakathi kanye ne-weld yangaphandle ekuqondeni kwe-longitudinal akufanelekile.
