Ukugoqa okubandayo ekushiseni kwe-recrystallization ngezansi okubizwa ngokuthi i-coil-rolled, i-hot-rolled coil njengento eluhlaza, kuvame ukusetshenziswa ekukhethweni kwe-asidi ukuze kukhishwe isikhumba se-oxide ngemva kokugoqa okubandayo, umkhiqizo ophelile unzima, ngenxa yomsebenzi obandayo uqina okubangelwa ukubola okuqhubekayo. abandayo rolling hard roll amandla, ukwandisa ubulukhuni, ukuqina kanye inkomba plastic kwehle, ngakho ukusebenza isitembu kuzowohloka, ingasetshenziswa kuphela deformation elula izingxenye.
Ikhoyili eqinile ingasetshenziswa njengempahla eluhlaza, idiphu elishisayo efektri yamadiphu yokufaka amadiphu ashisayo Amasethingi ngocingo oluxhunywe.
Isisindo sevolumu enzima ku-20 - ngokujwayelekile
Amathani angu-40, ikhoyili yensimbi, ekamelweni lokushisa ukuze kuqhutshwe amavolumu okuqoqwa okushisayo.
Izici zomkhiqizo ogoqiwe obandayo: ngoba akukho ngemuva kokwelashwa kwe-annealing, ubulukhuni bukhulu kakhulu (
I-HRB ingaphezu kuka-90)
, ukucutshungulwa kokusebenza kwemishini kubi, okulula kuphela okunokuqondisa kungaphansi kokucutshungulwa kokugoba kwe-90 degree.
Okulula, okugoqiwe okubandayo, kusekelwe ekucubunguleni ikhoyili egoqelwe ngokushisayo, ngokuvamile iyashiswa -

Amakhaza agingqa inqubo yokucubungula.
Ukugoqa okubandayo kungaphansi kwesimo sokucutshungulwa yi-hot rolling plate, kuyilapho inqubo yokwenza imishini yokugingqa izokwenza izinga lokushisa lensimbi yensimbi, noma kunjalo ebizwa ngokuthi i-cold rolling.
Ngenxa yokushisa okugoqeka phakathi kokuhlukahluka okubandayo okugoqekayo ekusebenzeni kokusebenza kuba kubi kakhulu, ukuqina kuphezulu kakhulu, ngakho-ke kufanele kudlule ekufakweni kwe-anneal ukuze kubuyiselwe izici zakhona zomshini, ngaphandle kokushunqiswa kunzima.
Ikhoyili eqinile ivamise ukusetshenziselwa ukwenza ngaphandle kokugoba, ukwelula imikhiqizo, 1.
Ngaphansi kukaziro ukujiya kuzo zombili izinhlangothi zenhlanhla eqinile noma ukugoba kwe-quadrilateral.
Umkhuhlane ugoqeke ngokuvamile ngemva kokwelashwa kokuhushula.
Kumele kusetshenziswe inqubo yamafutha abandayo agoqayo abandayo, izinzuzo zokusebenzisa uwoyela ogoqayo obandayo yilezi: 1, nciphisa ngempumelelo i-coefficient yokungqubuzana, unikeze amandla okugoqa ahambisanayo, ukusetshenziswa kwamandla aphansi, imingcele egculisayo yokugoqa;
2, yenza ukukhanya okuphezulu okungaphezulu nokuqina okufanayo kokubambezeleka kokugoqa;
3, umphumela omuhle wokupholisa, ungasusa ngokushesha ukugoqa okushisayo, uvikele umqulu kanye nocezu olugoqayo.
Ukusebenza kwe-Annealing kuhle, ngeke kukhiqize isenzakalo sokushiswa kwamafutha;
I-4, isebenze isikhathi esifushane sokulwa nokugqwala, inganikeza ukuvikelwa kwesikhashana kokugqwala kwezingcezu ezigoqiwe.
Kugoqwe okushisayo okugoqiwe okushisayo (
热轧)
Iyingxenye yomsebenzi oshisayo wenqubo yokugoqa.
Ukukhiqiza okuphezulu okugoqiwe okushisayo, isikali esikhulu, ukusetshenziswa kwamandla amancane, izindleko eziphansi, izinga eliphezulu lemishini, i-automation, ilungele ukukhiqizwa ngobuningi ngokulandelana, ingenye yezindlela ezibaluleke kakhulu zokucubungula ingcindezi yensimbi.
Okushisayo okugoqwe ngokucubungula ukumelana nokuguqulwa kwensimbi kuphansi futhi ipulasitiki futhi isetshenziswa kabanzi.
Kodwa njengoba izinga lokushisa eligoqiwe lingelula ukulilinganisa ngokulinganayo lapho liginqika, indawo engaphezulu ye-tin oxide ikhona, ukunemba kosayizi womkhiqizo kanye nokubamadlakadlaka kwengaphezulu kuyimikhiqizo egoqwayo ebandayo.
Iwumshini omkhulu wokugaya okushisayo.
Kusetshenziswa isigayo esishisayo, kukhona izigayo ezimbili, izigayo ezintathu, izigayo ezine eziphakeme, izigayo zohlobo lwe-Y, izigayo ezimbili eziphezulu, izigayo ezintathu. , i-cross rolling mill, i-universal mill kanye nazo zonke izinhlobo zomshini okhethekile nokunye.
Ngokwezidingo zokukhiqizwa kwezinhlobonhlobo zemikhiqizo, ikhwalithi yomkhiqizo, ukukhiqizwa, izimo zesayithi, njll., kunezinhlobo eziningi zokugaya ezishisayo zesakhiwo seshabhu yokusebenzela, njengokwakheka komshini owodwa, ikholomu eyodwa noma amaningi wesitimela esivulekile. ukuhleleka, uhlelo lokulandela umkhondo, ukuhlelwa kohlobo lokugoqa, uhlobo lwe-chessboard luhlotshisiwe, njll.
Inqubo yokukhiqiza i-hot rolling ngokuvamile ihlanganisa ukulungiswa kwezinto ezingavuthiwe, ukufudumeza, ukugoqa, ukuqeda nokunye okuningi.
I-hot rolling ingasetshenziselwa ukugoqa ingot yensimbi noma i-billet enkulu, ukukhiqizwa kwemikhiqizo emikhulu.
Njenge-ingot enkulu ekugingqikeni okungu-70 t ngaphakathi naseduze kuka-50 t omkhulu we-billet, khiqiza ukujiya kwepuleti eliwugqinsi elingu-500 mm, ipayipi lensimbi elingenamthungo elingu-1070 mm ububanzi, insimbi engu-1200 mm x 530 MMH kanye nomzila wesitimela ongu-78 kg/m, njll.
Enqubweni yokugoqa okushisayo, izinga lokushisa eligoqiwe liyancipha kancane kancane, ukumelana nokuguquguquka kwempahla kukhuphuka kancane kancane, ekugcineni akukwazi ukwenza indawo eshisayo.
Ngakho-ke akuwona usayizi wemikhiqizo egoqiwe eshisayo ingaba mncane kakhulu, ingaba ishidi eliwugqinsi elingu-1 mm kuphela, ipayipi lensimbi elingenamthungo elingu-20 mm, ububanzi obungu-5.
0 mm intambo, njll.
Umugqa.
Ngakho-ke akuwona usayizi wemikhiqizo egoqiwe eshisayo ingaba mncane kakhulu, ingaba ishidi eliwugqinsi elingu-1 mm kuphela, ipayipi lensimbi elingenamthungo elingu-20 mm, ububanzi obungu-5.
0 mm intambo, njll.
I-hot rolling ingaba nomthamo omkhulu wokukhiqiza, umkhiqizo wonyaka we-6 million t we-roll rolling mill, uma ikhona, umthamo wonyaka we-6 million t hot roll rolled DaiGangChang njll.
Imikhiqizo egoqiwe eshisayo ingahlukaniswa ngezici zokuma kwesigaba esiphambanayo somugqa ogoqiwe oshisayo, ipayipi lensimbi eligoqiwe elingenamthungo, insimbi egoqiwe eshisayo kanye nensimbi ekhethekile egoqa amakilasi amane.
I-Hot rolling by rolling way ihlukaniswe kakhulu ibe yi-longitudinal rolling, skew rolling kanye ne-rolling.
Umehluko phakathi kokugoqa okubandayo nokugoqiwe okushisayo, okubandayo okugoqelwe kwaba yizigaba 1 ukuze kuvunyelwe ingxenye yendawo yokubopha, engasebenzisa ngokugcwele umthamo wokuthwala ibha ngemuva;
I-buckling yendawo kanye nensimbi egoqiwe eshisayo ayivumeli isigaba esiphambene.
I-2, izimbangela zensimbi egoqiwe eshisayo kanye nokucindezeleka kwensimbi egoqiwe okubandayo kuhlukile, ngakho-ke ukusatshalaliswa kwesiphambano nakho kunomehluko omkhulu kakhulu.
Ingxenye yesiphambano sensimbi esakhiwe ngendlela ebandayo enezindonga ezincane ekusabalalisweni kokucindezeleka okuyinsalela igobile, futhi insimbi egoqiwe eshisayo noma insimbi eshiselwe ukusatshalaliswa kokucindezeleka kwensalela yensalela engxenyeni ephambanayo kuyifilimu encane.
3, insimbi egoqiwe eshisayo yamahhala iphakeme kunensimbi egoqiwe ebandayo, ngakho-ke izakhiwo zokuxubha zensimbi egoqwe zingcono kunensimbi egoqiwe ebandayo.
