Kokubili ukugoqa okushisayo nokubandayo kuyipuleti lensimbi noma izinqubo zokwenza iphrofayela, kunomthelela omkhulu esakhiweni nasezimpahleni zensimbi.

Ukuginqika kwensimbi ngokuyinhloko kuwukuginqika okushisayo, ukugoqa okubandayo kuvame ukusetshenziselwa ukukhiqiza insimbi encane neshidi lensimbi kanye nezinye izinsimbi zosayizi wokunemba.

Ukugoqa okujwayelekile okubandayo nokushisayo kwensimbi:

Intambo: 5.5-40 mm ububanzi, amakhoyili, wonke ashisayo aginqiwe.Ngemuva kokudweba okubandayo, kungokwezinto ezibandayo zokudweba.

Insimbi Eyindilinga: Ngaphezu kokunemba kobukhulu bezinto ezikhanyayo ngokuvamile zishisa zigoqekile, kodwa futhi zenziwe ngomgunyathi (iminonjana yangaphezulu yokubumba).

Insimbi ye-Strip: kubanda okushisayo kugoqiwe, kubanda kugoqeke ngokujwayelekile kube mncane.

Ipuleti lensimbi: ipuleti eligoqiwe elibandayo ngokuvamile lincane, njengepuleti lemoto;Ipuleti eliwugqinsi elishisayo eligoqayo elishisayo, futhi ukujiya okubandayo okubandayo, ukubukeka kuhlukile ngokusobala.

I-engeli yensimbi: konke okushisayo kugoqwe.

Ishubhu lensimbi: elishiselwe elishisayo eligoqiwe futhi liyabanda.

Isiteshi ne-H beam: okugoqiwe okushisayo.

Ibha yensimbi: impahla egoqiwe eshisayo.

Okushisayo kugoqiwe

Ngokwencazelo, i-ingot yensimbi noma i-billet kunzima ukuyikhubaza nokuyicubungula ekamelweni lokushisa.Ivamise ukushisisa ibe ngu-1100 ~ 1250℃ ukuze igingqike.Le nqubo yokugingqa ibizwa ngokuthi ukugoqa okushisayo.

Izinga lokushisa elinqanyuliwe lokuginqika okushisayo livamise ukuba ngu-800 ~ 900℃, bese lipholiswa ngokujwayelekile emoyeni, ngakho-ke isimo sokuginqika esishisayo silingana nokwelashwa okujwayelekile.

Insimbi eningi igoqwa ngokuginqika okushisayo.Insimbi egoqiwe eshisayo, ngenxa yokushisa okuphezulu, ubuso bokwakheka kongqimba lweshidi le-oxide, ngaleyo ndlela linokumelana okuthile kokugqwala, kungagcinwa emoyeni ovulekile.

Kodwa-ke, lolu ungqimba lwensimbi ye-oxide luphinde lwenze ingaphezulu lensimbi egoqiwe ibe mahhedla futhi ubukhulu buguquguquke kakhulu, ngakho-ke insimbi enobuso obushelelezi, usayizi onembile kanye nezakhiwo ezinhle zomshini kufanele isetshenziswe njengempahla eluhlaza bese kubanda igingqika.

Izinzuzo:

Ukwakha isivinini, isivuno esiphezulu, futhi ungalimazi ukugqoka, kungenziwa ezinhlobonhlobo zezinhlobo zesiphambano, ukuhlangabezana nezidingo zemibandela yokusetshenziswa;Ukugoqa okubandayo kungaveza ukuguqulwa okukhulu kwepulasitiki yensimbi, ngaleyo ndlela kukhuphule iphuzu lokukhiqiza lensimbi.

Ububi:

1. Nakuba kungekho ukucindezelwa kwepulasitiki okushisayo enqubweni yokubunjwa, kusekhona ukucindezeleka okuyinsalela esigabeni, okuzothinta nakanjani izakhiwo zensimbi ezihlangene nezendawo;

2. Ingxenye egoqekile ebandayo ngokuvamile iyisigaba esivulekile, okwenza ukuqina kwe-torsion kwamahhala kwesigaba kube phansi.Kulula ukusonteka lapho igobile, futhi kulula ukugoba nokusonteka lapho icindezelwa, futhi ukumelana nokudumba kubi.

3. Ugqinsi lwezindonga zensimbi emise okugoqeke ngokubanda luncane, futhi akukho ukujiya ekhoneni lapho ipuleti lixhumeka khona, ngakho linamandla abuthakathaka okuthwala umthwalo ogxilile wendawo.

Amakhaza aginqike

Ukugoqa okubandayo kubhekisela endleleni yokugingqa yokushintsha ukuma kwensimbi ngokucindezela insimbi ngaphansi kwengcindezi ye-roller ekamelweni lokushisa.Kubizwa ngokuthi ukugoqa okubandayo, nakuba inqubo iphinde ishise insimbi.Ukucacisa kakhudlwana, ukugoqa okubandayo kusebenzisa amakhoyili ensimbi ashisayo njengezinto ezingavuthiwe, ezicutshungulwa ngaphansi kwengcindezi ngemva kokukhetha i-asidi ukuze kukhishwe isikali se-oxide, futhi imikhiqizo eqediwe igoqwa amakhoyili aqinile.

Ngokuvamile insimbi egoqiwe ebandayo efana nama-galvanized, ipuleti lensimbi enombala kufanele lifakwe emanzini, ngakho-ke ipulasitiki kanye nobude nakho kuhle, kusetshenziswa kakhulu ezimotweni, ezintweni zasendlini, zehadiwe nakwezinye izimboni.Ingaphezulu lepuleti eligoqekile linezinga elithile lokushelela, futhi isandla sizwakala sibushelelezi, ikakhulukazi ngenxa yokuqoqwa.Indawo engaphezulu yepuleti eligoqiwe alikwazi ukuhlangabezana nezidingo, ngakho-ke umugqa wensimbi ogoqiwe oshisayo udinga ukugoqwa obandayo, futhi ubukhulu bomucu wensimbi egoqiwe ngokuvamile bungu-1.0mm, futhi umugqa wensimbi obandayo ungafinyelela ku-0.1mm. .I-Hot rolling igingqika ngaphezu kwezinga lokushisa elicwebezelayo, ukugoqa okubandayo kuginqika ngezansi kwezinga lokushisa elicwebezelayo.

Ukushintsha komumo wensimbi okubangelwa ukugoqeka okubandayo kungokwe-deformation eqhubekayo ebandayo.Ukuqina kwamakhaza okubangwa yile nqubo kwandisa amandla nobulukhuni bekhoyili eqinile egoqiwe futhi kunciphisa ukuqina kanye nenkomba yepulasitiki.

Okokugcina, ukugoqa okubandayo kulimaza ukusebenza kwesitembu futhi umkhiqizo ulungele izingxenye ezikhubazekile.

Izinzuzo:

Ingacekela phansi ukwakheka kwensimbi yensimbi, icwenge usayizi wokusanhlamvu wensimbi, futhi isuse amaphutha e-microstructure, ukuze isakhiwo sensimbi sihlanganiswe futhi izakhiwo zemishini zithuthukiswe.Lokhu kuthuthukiswa kubonakala ngokuyinhloko ekugibeleni, ukuze insimbi ingabi yi-isotropic ngezinga elithile.Amabhamuza, imifantu kanye nokuxega okwakhiwa ngesikhathi sokubunjwa kungashiselwa ngaphansi kwezinga lokushisa eliphezulu nokucindezela.

Ububi:

1. Ngemuva kokushisa okushisayo, ama-non-metallic inclusions (ikakhulukazi ama-sulfide nama-oxides, kanye nama-silicates) ensimbi ahlanganiswe ne-laminate.I-Delamination iwohloza kakhulu izici eziqinile zensimbi eduze kogqinsi futhi ingase ibangele ukudabuka phakathi kwe-interlaminar ngesikhathi sokuncipha kokushisela.Ubunzima bendawo obubangelwa ukushwabana kwe-weld kuvame izikhathi ezimbalwa zobunzima bephoyinti lesivuno, elikhulu kakhulu kunalelo elibangelwa umthwalo.

2. Ukucindezeleka okusalayo okubangelwa ukupholisa okungalingani.Ukucindezeleka okuyinsalela ukucindezeleka kwangaphakathi kwesigaba sokuzilinganisa ngaphandle kwamandla angaphandle.Zonke izinhlobo zensimbi ezigoqiwe ezishisayo zinalolu hlobo lokucindezeleka okusalayo.Ubukhulu besigaba sensimbi yesigaba esijwayelekile, kukhulu ukucindezeleka okusalayo.Nakuba ukucindezeleka okusalayo kuwukulingana kwesigaba sokuzimela, kunomphumela othile ekusebenzeni kwelungu lensimbi ngaphansi kwamandla angaphandle.Okufana ne-deformation, ukuzinza, ukumelana nokukhathala nezinye izici kungase kube nemiphumela emibi.

Isiphetho:

Umehluko phakathi kokugoqa okubandayo nokugoqa okushisayo ikakhulukazi izinga lokushisa lenqubo yokugingqa."Ukubanda" kubonisa izinga lokushisa elivamile, futhi "kushisa" kubonisa izinga lokushisa eliphezulu.

Ngokombono we-metallic, umngcele phakathi kokugoqa okubandayo nokugoqa okushisayo kufanele uhlukaniswe ngezinga lokushisa le-recrystallization.Okusho ukuthi, ukugoqa ngezansi kwezinga lokushisa le-recrystallization kuyabanda, futhi ukugoqa ngaphezu kwezinga lokushisa lokuvuselela kabusha kuyashisa.Izinga lokushisa recrystallization yensimbi kuyinto 450 ~ 600 ℃.
