Embonini yensimbi, sivame ukuzwa mayelana nemibono yokugoqa okushisayo nokugoqa okubandayo, ngakho-ke ziyini?
Eqinisweni, amabhilidi ensimbi akhiqizwa endaweni yokwenza insimbi ayimikhiqizo eseqediwe kancane kuphela futhi kufanele agingqelwe emshinini wokugaywa ukuze abe imikhiqizo yensimbi efanelekayo.Ukuginqika okushisayo nokugoqa okubandayo yizinqubo ezimbili ezivamile zokugingqa.
Ukugoqa kwensimbi kwenziwa ikakhulukazi ngokugoqa okushisayo, kuyilapho ukugoqa okubandayo kusetshenziswa ikakhulukazi ukukhiqiza izingxenye zensimbi ezinosayizi omncane namapuleti amancane.
Okulandelayo izimo ezivamile ezibandayo nezishisayo zensimbi:
Ucingo: olunobubanzi obungamamilimitha angu-5.5-40, luhlanganiswe ngamakhoyili, zonke zenziwe ngezinto ezishisayo.Ngemuva kokudweba okubandayo, kungokwezinto ezibandayo ezidonswayo.
Insimbi eyindingilizi: Ngaphezu kokunemba kwezinto ezikhanyayo ezinosayizi, imvamisa iyashisa futhi kukhona nezinto ezibunjiwe (ezinamamaki okubumba phezulu).
Insimbi ye-strip: kokubili okugoqiwe okushisayo kanye nokugoqwa okubandayo kuyatholakala, futhi okokusebenza okugoqelwe okubandayo ngokuvamile kuba mncane.
Ipuleti lensimbi: Ipuleti eligoqiwe elibandayo ngokuvamile lincanyana, njengepuleti lezimoto;Kunamapuleti amaningi aphakathi nendawo nawugqinsi agoqelwe ashisayo, amanye anogqinsi olufana nolwabandayo, kodwa ukubukeka kwawo kuhluke kakhulu.I-engeli yensimbi: konke kushiswe.
Amapayipi ensimbi: womabili ashiselwe, agoqelwe ashisayo, namakhaza.
Insimbi yesiteshi kanye nensimbi emise okwe-H: igoqelwe ngokushisayo
Izinsimbi zensimbi: izinto ezigoqelwe ngokushisayo.
Ukuginqika okushisayo nokugoqa okubandayo yizinqubo zombili zokwenza amapuleti ensimbi noma amaphrofayili, anomthelela omkhulu kusakhiwo esincane kanye nezakhiwo zensimbi.
Ukuginqika kwensimbi ngokuyinhloko kusekelwe ekugoqeni okushisayo, kuyilapho ukugoqa okubandayo kuvame ukusetshenziselwa ukukhiqiza insimbi enosayizi onembile njengengxenye yensimbi namapuleti amancane.
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 kusetshenziswa indlela yokugoqa eshisayo.Insimbi ehanjiswa esimweni esishisayo, ngenxa yokushisa okuphezulu, yakha ungqimba lwe-iron oxide ebusweni, olunezinga elithile lokumelana nokugqwala futhi lingagcinwa ngaphandle.Kodwa lolu ngqimba lwe-iron oxide luphinde lwenze ingaphezulu lensimbi egoqwe ngokushisa libe mahhedla, libe nokuguquguquka okuphawulekayo kosayizi.Ngakho-ke, insimbi edinga indawo ebushelelezi, usayizi oqondile, kanye nezakhiwo ezinhle zemishini kufanele ikhiqizwe kusetshenziswa imikhiqizo egoqwe kancane noma eqediwe njengezinto ezingavuthiwe bese igoqwa ngokubandayo.
Izinzuzo: Isivinini sokubumba esisheshayo, isivuno esikhulu, futhi akukho monakalo embotsheni.Ingenziwa ibe amafomu ahlukene ahlukene ukuze ihlangabezane nezidingo zemibandela yokusetshenziswa;Ukugoqa okubandayo kungabangela ukuguqulwa okuphawulekayo kwepulasitiki yensimbi, ngaleyo ndlela kwandise iphuzu layo lokukhiqiza.
Ukungalungi: 1. Nakuba kungekho ukucindezelwa kwepulasitiki okushisayo phakathi nenqubo yokubunjwa, ukucindezeleka okusalayo kusekhona esigabeni, okuthinta ngokungenakuvinjelwa izici zensimbi eziphelele nezendawo;
2. Isitayela sensimbi egoqwe ngokubanda ngokuvamile siyisigaba esivulekile, esinciphisa ukuqina kwe-torsional kwamahhala kwesigaba.I-Torsion ijwayele ukwenzeka lapho igotshwa, futhi ukugoba ukugoba kujwayele ukwenzeka lapho kucindezelwe, okuholela ekusebenzeni kabi kwe-torsion;
3. Insimbi eyakhiwe egoqwe ngokubanda inobukhulu obuncane bodonga futhi ayiqini emakhoneni oxhumo lwepuleti, okuholela ekhonweni elibuthakathaka lokumelana nemithwalo egxilile yendawo.
Ukuginqika okubandayo kubhekisela endleleni yokugingqa yokuguqula isimo sensimbi ngokuyikhama ngokucindezela kwerola eligoqayo ekamelweni lokushisa.Nakuba inqubo yokucubungula ingase futhi ibangele ipuleti lensimbi ukuthi lishise, isabizwa ngokuthi ukugoqa okubandayo.
Ngokukhethekile, ukugoqa okubandayo kusebenzisa amakhoyili ensimbi agoqelwe ashisayo njengezinto zokusetshenziswa, kugezwa nge-asidi ukuze kukhishwe izikali ze-oxide, bese kucutshungulwa ukucindezela ukuze kukhiqizwe amakhoyili aqinile.Ngokuvamile, insimbi egoqelwe ngokubanda njengamapuleti ensimbi anombala adinga ukuxhunywa, ngakho-ke ipulasitiki nobude bawo nakho kuhle, futhi asetshenziswa kakhulu ezimbonini ezifana nezimoto, izinto zasendlini, nehardware.
Ingaphezulu leshidi eligoqiwe ngokubanda linezinga elithile lokushelela, futhi lizwakala libushelelezi uma ulithinta, ikakhulukazi ngenxa yokugeza nge-asidi.Ubushelelezi obungaphezulu bamapuleti agingqiwe ashisayo ngokuvamile akuhlangabezani nezidingo, ngakho-ke amapheshana ensimbi agoqelwe ashisayo adinga ukugoqwa okubandayo.Ugqinsi oluncane kakhulu lwemichilo yensimbi egoqelwe eshisayo ngokuvamile luyi-1.0mm, kanti amapheshana ensimbi agoqeke abandayo angafinyelela ku-0.1mm.
I-Hot rolling igingqika ngaphezu kwezinga lokushisa elicwebezelayo, kuyilapho ukugoqa okubandayo kuginqika ngaphansi kwezinga lokushisa elicwebezelayo.Ukushintsha kwesimo sensimbi okubangelwa ukugoqa okubandayo kungokwase-deformation ebandayo eqhubekayo, futhi ukuqina komsebenzi obandayo okubangelwa le nqubo kwandisa amandla nobulukhuni bekhoyili eqinile egoqiwe, kuyilapho ukuqina kanye ne-plasticity index kuncipha.
Okokugcina, ukugoqa okubandayo kulimaza ukusebenza kwesitembu futhi imikhiqizo ilungele izingxenye ezikhubazekile.
Izinzuzo: Ingacekela phansi ukwakheka kwama-ingots ensimbi, icwenge usayizi wokusanhlamvu wensimbi, futhi isuse amaphutha ku-microstructure, ngaleyo ndlela yenze isakhiwo sensimbi siminyene futhi sithuthukise izakhiwo zaso eziwumshini.Lokhu kuthuthukiswa kubonakala ngokuyinhloko ekuqondeni kokugoqa, ukuze insimbi ingabi yi-isotropic ngezinga elithile;Amabhamuza, imifantu, nokuxega okwakhiwe ngesikhathi sokuthululwa nakho kungashiselwa ngaphansi kwezinga lokushisa eliphezulu nokucindezela.
Ukungalungi: 1. Ngemuva kokugoqa okushisayo, okufakiwe okungezona ezensimbi (ikakhulukazi ama-sulfide nama-oxides, kanye nama-silicates) ngaphakathi kwensimbi kucindezela amashidi amancane, okuholela e-delamination.Ukwendlalela kuwohloza kakhulu ukusebenza okuqinile kwensimbi eduze kogqinsi, futhi kungenzeka ukuklebhuka kwe-interlayer ngesikhathi sokuncipha kokushisela.Ubunzima bendawo obubangelwa ukushwabana kwe-weld seam ngokuvamile kufinyelela izikhathi eziningana isivuno samaphuzu, okuyinto enkulu kakhulu kunobunzima obubangelwa umthwalo;
2. Ukucindezeleka okusalayo okubangelwa ukupholisa okungalingani.Ukucindezeleka okusalayo kubhekisela ekucindezelekeni kokuthi ukuzimela kulinganisa ngaphakathi ngaphandle kwamandla angaphandle, futhi kukhona ezigabeni ezihlukahlukene zensimbi ezigoqelwe ngokushisayo.Ngokuvamile, ubukhulu besigaba sensimbi bukhulu, kukhulu ukucindezeleka okusalayo.Nakuba ukucindezeleka okuyinsalela kuwukuzilinganisa, kusenomthelela othile ekusebenzeni kwezingxenye zensimbi ngaphansi kwamandla angaphandle.Kungase kube nemiphumela emibi ekuguqukeni, ukuzinza, ukumelana nokukhathala, nezinye izici.
