Ingaphezulu lepuleti eligoqiwe elibandayo linokukhanya okuthile futhi lizwakala libushelelezi, elifana nenkomishi yensimbi evamile esetshenziselwa amanzi okuphuza.2. Uma ipuleti eligoqiwe elishisayo lingagcotshiwe, lifana nobuso bamapuleti ensimbi amaningi ajwayelekile emakethe.Indawo egqwalile ibomvu, futhi ngaphandle kokugqwala inombala onsomi-omnyama (i-iron oxide).

Izinzuzo zokusebenza zeshidi eligoqiwe elibandayo neshidi eligoqiwe elishisayo yilezi:

(1) ukunemba okuphezulu, umehluko wokujiya womugqa ogoqiwe obandayo awudluli ku-0.01~0.03mm.

(2) Usayizi omncane, okugoqa okubandayo okungagoqa umugqa wensimbi ongu-0.001mm;Ukuginqika okushisayo manje kufinyelela ubukhulu obuncane obungu-0.78mm.

(3) Ikhwalithi ephezulu, ipuleti lensimbi eligoqiwe elibandayo lingakhiqiza indawo yesibuko;Ingaphezulu lepuleti eligoqiwe elishisayo lineziphambeko njenge-iron oxide kanye ne-pitting.

(4) Ishidi eligoqiwe elibandayo lingalungiswa ngokuya ngezidingo zomsebenzisi zezindawo zalo ezisebenzayo njengamandla aqinile kanye nezakhiwo zenqubo ezifana nezakhiwo zokugxiviza.

Ukugoqa okubandayo nokugoqa okushisayo ubuchwepheshe bokugoqa bensimbi obuhlukene, njengoba negama lisho, ukugoqa okubandayo ukubopha insimbi ekamelweni lokushisa, ubulukhuni bale nsimbi bukhulu.I-Hot rolling yilapho insimbi iboshwa ndawonye ezingeni lokushisa eliphezulu.Ishidi eligoqiwe elishisayo linobulukhuni obuphansi, ukucubungula okulula kanye ne-ductility enhle.Cold rolled sheet ubulukhuni kuphezulu, ukucubungula kunzima, kodwa akulula deformation, amandla aphezulu.Amandla epuleti eligoqiwe elishisayo aphansi uma kuqhathaniswa, izinga eliphezulu licishe libe (i-oxidation, isiphetho esiphansi), kodwa ipulasitiki enhle, ipuleti eliwugqinsi eliphakathi nendawo, ipuleti eligoqiwe elibandayo: amandla aphezulu, ukuqina okuphezulu, ukuqeda okuphezulu okuphezulu, ngokuvamile ipuleti elincane, lingasetshenziswa njenge ipuleti lokunyathela.Ipuleti lensimbi eligoqiwe elishisayo, izakhiwo zemishini ziphansi kakhulu kunokucubungula okubandayo, futhi zingaphansi kokucubungula ukubunjwa, kodwa linokuqina okungcono kanye ne-ductility.Ipuleti lensimbi eligoqiwe elibandayo ngenxa yezinga elithile lokuqina komsebenzi, ukuqina okuphansi, kodwa lingafinyelela isilinganiso esihle se-flexural, esisetshenziselwa ukugoba izingcezu zasentwasahlobo ezibandayo nezinye izingxenye, ngesikhathi esifanayo ngoba iphuzu lokukhiqiza liseduze namandla aqinile, ukusetshenziswa kwengozi akubikezeli, lapho umthwalo udlula umthwalo ovumelekile ujwayele izingozi.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.Insimbi eningi igoqwa ngokuginqika okushisayo.Kodwa-ke, ngenxa yokuthi ingaphezulu lensimbi kulula ukukhiqiza ishidi le-oxide ekushiseni okuphezulu, ingaphezulu lensimbi eshisayo egoqwe ilukhuni futhi ubukhulu bushintshashintsha kakhulu, ngakho-ke insimbi enobuso obushelelezi, usayizi onembile kanye nezakhiwo ezinhle zomshini kuyadingeka, futhi kuyashisa. imikhiqizo egoqiwe ecishe iqedwe noma imikhiqizo eqediwe isetshenziswa njengezinto ezingavuthiwe bese ikhiqizwa ngendlela yokugoqa ebandayo.Ukuginqika ekamelweni lokushisa ngokuvamile kuqondwa njengokugoqa okubandayo.Ngokombono wesayensi yensimbi, umngcele phakathi kokugoqa okubandayo nokugoqa okushisayo kufanele uhlukaniswe ngokushisa kwekristali.Okusho ukuthi, ukugoqa ngezansi kwezinga lokushisa le-recrystallization kuyabanda, futhi ukugoqa ngaphezu kwezinga lokushisa lokuvuselela kabusha kuyashisa.Izinga lokushisa recrystallization yensimbi kuyinto 450 ~ 600 ℃.Ukugoqa okushisayo, njengoba negama lisho, izingxenye ezigoqayo zokushisa okuphezulu, ngakho-ke ukumelana ne-deformation kuncane, kungafinyelela ukuguqulwa okukhulu.Uma sithatha ukuginqika kwepuleti lensimbi njengesibonelo, ukujiya kwe-billet eqhubekayo yokuphonsa cishe ku-230mm, futhi ngemva kokugingqika nokuqeda ukugoqa, ukujiya kokugcina kungu-1~20mm.Ngesikhathi esifanayo, ngenxa yokuthi isilinganiso sokujiya se-steel plate sincane, ukunemba kwe-dimensional kuphansi kakhulu, akulula ukuvela inkinga yokuma, ikakhulukazi ukulawula umqhele.I-microstructure kanye nezakhiwo zemishini ze-strip steel zingalawulwa ngokulawula izinga lokushisa eligoqayo, izinga lokushisa eliginqikayo kanye nezinga lokushisa elincibilikayo.Ukugoqa okubandayo, ngokuvamile ayikho inqubo yokushisisa ngaphambi kokugingqika.Kodwa-ke, ngenxa yokuthi ubukhulu be-strip buncane, kulula ukuvela inkinga yomumo.Ngaphezu kwalokho, ngemuva kokuqedwa okubandayo sekuqediwe umkhiqizo, ngakho-ke, ukuze kulawulwe ukunemba kwe-dimensional kanye nekhwalithi yangaphezulu ye-strip steel, kusetshenziswa inqubo eyisicefe kakhulu.Cold rolling umugqa wokukhiqiza yinde, imishini eyengeziwe, inqubo eyinkimbinkimbi.Ngokuthuthukiswa kwezimfuneko zabasebenzisi ekunembeni kobukhulu, umumo kanye nekhwalithi yangaphezulu ye-strip steel, kukhona amamodeli okulawula amaningi, amasistimu e-L1 ne-L2 nezindlela zokulawula ukuma kumshini wokugaya obandayo kunasemshinini wokugoqa oshisayo.Ngaphezu kwalokho, izinga lokushisa le-roller ne-strip libuye libe inkomba ebalulekile yokulawula.Imikhiqizo egoqiwe ebandayo kanye nomugqa weshidi lomkhiqizo ogoqiwe oshisayo, umehluko phakathi kwenqubo yangaphambilini nenqubo elandelayo, imikhiqizo egoqiwe eshisayo iyimpahla eluhlaza yemikhiqizo egoqiwe ebandayo, igoqwe elibandayo ngemuva kokukhetha umshini wekhoyili wensimbi oshisayo usebenzisa isigayo, ukugoqa, kukhona ukucubungula okubandayo, ikakhulukazi ukugoqa ipuleti eligoqiwe eliwugqinsi libe yizicaciso ezincane zepuleti eligoqiwe elibandayo, Imvamisa njengepuleti eligoqiwe elingu-3.0mm elishisayo emshinini wokugoqa lingakhiqiza ikhoyili egoqiwe ebandayo engu-0.3-0.7mm, umgomo oyinhloko ukusebenzisa umgomo we-extrusion ukuguqulwa okuphoqelelwe.
