Eqinisweni, amabhilidi ensimbi avela emshinini wensimbi ayimikhiqizo eseqediwe kancane, futhi kufanele agingqelwe emshinini wokugaywa ngaphambi kokuba abe imikhiqizo yensimbi efanelekayo.Ukuginqika okushisayo nokugoqa okubandayo yizinqubo ezimbili ezivamile zokugingqa.Ukuginqika kwensimbi ngokuyinhloko kugoqeka ngokushisa, futhi ukugoqa okubandayo kusetshenziselwa ikakhulukazi ukukhiqiza izingxenye ezincane namashidi.Okulandelayo yizinsimbi ezigoqiwe ezibandayo nezigoqelwe ngokushisayo: Ucingo: 5.5-40 mm ububanzi, olugoqiwe, zonke zigoqelwe ngokushisa.Ngemuva kokudweba okubandayo, kungokwezinto ezidonswayo ezibandayo.Insimbi eyindingilizi: Ngaphezu kwempahla ekhanyayo enobukhulu obunembile, ivamise ukugoqa, futhi kukhona nezinto zokubumba (izimpawu zokubumba phezulu).Insimbi ye-strip: kokubili okugoqiwe okushisayo nokugoqekayo, nezinto ezigoqekayo ezibandayo ngokuvamile ziba mncane.Ipuleti lensimbi: amapuleti agoqelwe ngamakhaza ngokuvamile azacile, njengamapuleti ezimoto;kunamapuleti aphakathi nendawo nasindayo amaningi aginqike ashisayo, anogqinsi olufana nalawo agqitshwe abandayo, futhi ukubukeka kwawo kuhlukile ngokusobala.I-engeli yensimbi: konke okushisayo kugoqwe.Ipayipi lensimbi: Kokubili eligoqiwe elishisayo nelidonswa ngokubanda kuyatholakala.Insimbi yesiteshi kanye ne-H-beam: i-hot rolled.Ibha yokuqinisa: impahla egoqiwe eshisayo.
Kokubili ukugoqa okushisayo nokubandayo kuyizinqubo zokwenza amapuleti ensimbi noma amaphrofayili, futhi anomthelela omkhulu esakhiweni nasezimpahleni zensimbi.Ukugingqika kwensimbi kusekelwe ngokuyinhloko ekugoqeni okushisayo, futhi ukugoqa okubandayo kuvame ukusetshenziselwa ukukhiqizwa kwezigaba ezincane namashidi anezilinganiso eziqondile.Izinga lokushisa elinqanyuliwe lokuginqika okushisayo livamise ukuba ngu-800 kuya ku-900 ° C, bese lipholiswa ngokujwayelekile emoyeni, ngakho-ke isimo sokugoqeka esishisayo silingana nokwelashwa okujwayelekile.Izinsimbi eziningi zigoqwa ngendlela yokugoqa okushisayo.Ngenxa yokushisa okuphezulu, insimbi ehanjiswa esimweni esishisayo inongqimba lwesikali se-iron oxide ebusweni, ngakho inokumelana nokugqwala okuthile futhi ingagcinwa emoyeni ovulekile.Kodwa-ke, lolu ngqimba lwesikali se-iron oxide lwenza ingaphezulu lensimbi egoqwe ngokushisa libe mahhedla futhi nosayizi uguquguquke kakhulu.Ngakho-ke, insimbi enobuso obushelelezi, usayizi onembile kanye nezakhiwo ezinhle zemishini iyadingeka, futhi imikhiqizo eqediwe eshisayo eqediwe noma imikhiqizo eqediwe isetshenziswa njengezinto zokusetshenziswa zokukhiqiza okubandayo.Izinzuzo: isivinini sokwenza ngokushesha, ukuphuma okuphezulu, futhi akukho monakalo ekugqokeni, kungenziwa kube amafomu ahlukahlukene e-cross-sectional ukuhlangabezana nezidingo zemibandela yokusetshenziswa;ukugoqa okubandayo kungabangela ukuguqulwa okukhulu kwepulasitiki yensimbi, ngaleyo ndlela kuthuthukise isivuno sephoyinti lensimbi.Ukungalungi: 1. Nakuba kungekho ukucindezelwa kwepulasitiki okushisayo phakathi nenqubo yokubunjwa, kusekhona ukucindezeleka okusalayo esigabeni, okuzothinta nakanjani izici zensimbi eziphelele nezendawo;2. Ingxenye yensimbi egoqwe ngokubanda ngokuvamile iyisigaba esivulekile, okwenza isigaba sibe mahhala.Ukuqina kwe-torsional kuphansi.Ijwayele ukuba ne-torsion ngesikhathi sokugoba, futhi ukugoba kwe-torsional buckling kujwayele ukwenzeka ngesikhathi sokucindezelwa, futhi ukusebenza kwe-torsional kubi;3. Ugqinsi lwezindonga zensimbi eyakhayo ezigoqekayo luncane, futhi aluqiniswanga emagumbini lapho amapuleti axhunywe khona, ngakho angakwazi ukumelana nengcindezi yendawo.Ikhono lokugxilisa imithwalo libuthakathaka.Ukuginqika okubandayo Ukugoqa okubandayo kubhekisela endleleni yokugingqa yokuguqula isimo sensimbi ngokukhipha insimbi ngokucindezela komqulu ezingeni lokushisa elilingana negumbi.Nakuba ukucubungula kuphinde kushise ishidi lensimbi, kusabizwa ngokuthi ukugoqa okubandayo.Ngokuqondile, ikhoyili yensimbi egoqwe ngokushisayo yokugoqa okubandayo isetshenziswa njengezinto ezingavuthiwe, futhi isikali se-oxide sisuswa ngokukhethwa, bese kucutshungulwa ingcindezi, futhi umkhiqizo ophelile uyikhoyili egoqwe kanzima.Ngokuvamile, insimbi egoqelwe ngokubanda njengensimbi eyisithako esiqinile kanye nepuleti lensimbi enombala kufanele ivalwe, ngakho-ke ipulasitiki nobude nakho kuhle, futhi isetshenziswa kakhulu ezimotweni, ezintweni zikagesi zasendlini, kwihardware nakwezinye izimboni.Ingaphezulu leshidi eligoqwe elibandayo linezinga elithile lokushelela, futhi isandla sizizwa sibushelelezi, ikakhulukazi ngenxa yokukhetha.Indawo engaphezulu yeshidi eligoqelwe ngokushisayo ngokuvamile ayihlangabezani nezidingo, ngakho-ke umucu wensimbi ogoqelwe oshisayo udinga ukugoqwa obandayo.Umucu wensimbi omncane ogoqeke oshisayo ngokuvamile ungu-1.0mm, kanti umugqa wensimbi ogoqeke obandayo ungafinyelela ku-0.1mm.I-Hot rolling igingqika ngaphezu kwezinga lokushisa elicwebezelayo, futhi ukugoqeka okubandayo kuginqika ngezansi kwezinga lokushisa elicwebezelayo.Ukuguqulwa kwesimo sensimbi ngokugoqa okubandayo kungokwase-deformation ebandayo eqhubekayo, futhi ukuqina komsebenzi obandayo okubangelwa le nqubo kwandisa amandla, ukuqina nokuqina kanye nenkomba yepulasitiki yekhoyili eqinile egoqiwe.Ukuze kusetshenziswe ekugcineni, ukugoqa okubandayo kulimaza izakhiwo zokugxiviza, futhi umkhiqizo ulungele izingxenye ezilula zokuguquguquka.Izinzuzo: Ingacekela phansi ukwakheka kwe-ingot, icwenge okusanhlamvu kwensimbi, futhi isuse amaphutha e-microstructure, ukuze isakhiwo sensimbi siminyene futhi izakhiwo zemishini zithuthukiswe.Lokhu kuthuthukiswa kubonakala ngokuyinhloko ekuqondeni kwe-rolling, ukuze insimbi ingabi umzimba we-isotropic ngezinga elithile;ama-bubbles, imifantu kanye ne-porosity eyenziwe ngesikhathi sokubunjwa kungabuye kuhlanganiswe ngaphansi kwesenzo sokushisa okuphezulu nokucindezela.Ukungalungi: 1. Ngemva kokugoqa okushisayo, ama-non-metallic inclusions (ikakhulukazi ama-sulfides nama-oxides, nama-silicates) ngaphakathi kwensimbi acindezelwa abe amashidi amancane, futhi i-delamination iyenzeka.I-Delamination ilimaza kakhulu izakhiwo eziqinile zensimbi ngogqinsi, futhi kunethuba lokudabuka phakathi kwe-interlaminar njengoba i-weld incipha.Ubunzima bendawo obubangelwa ukuncipha kwe-weld ngokuvamile bufinyelela izikhathi eziningana isivuno samaphuzu, okuyinto enkulu kakhulu kunobunzima obubangelwa umthwalo;2. Ukucindezeleka okusalayo okubangelwa ukupholisa okungalingani.Ukucindezeleka okuyizinsalela ukucindezeleka kokulingana kwangaphakathi kwesigaba ngaphandle kwamandla angaphandle.Insimbi yesigaba esigoqelwe ngokushisayo yezigaba ezihlukahlukene inokucindezeleka okuyinsalela okunjalo.Ngokuvamile, ubukhulu besigaba sensimbi yesigaba esikhulu, kukhulu ukucindezeleka okusalayo.Nakuba ukucindezeleka okusalayo kuzimele, kusenethonya elithile ekusebenzeni kwelungu lensimbi ngaphansi kwesenzo samandla angaphandle.Isibonelo, kungase kube nemiphumela emibi ekuguquguqukeni, ekuzinzeni, nokumelana nokukhathala.
