ukuqina kwepuleti lensimbi eligoqiwe elishisayo liphansi, ukucubungula okulula, i-ductility yinhle.Cold rolled sheet ubulukhuni kuphezulu, ukucubungula kunzima, kodwa akulula deformation, amandla aphezulu.Amandla epuleti eligoqiwe elishisayo aphansi uma kuqhathaniswa, ikhwalithi ephezulu cishe (ukuphela kwe-oxidation ephansi), kodwa ipulasitiki enhle, ipuleti eliwugqinsi eliphakathi nendawo, ipuleti eligoqiwe elibandayo: amandla aphezulu nobulukhuni obuphezulu, isiphetho esiphezulu, ngokuvamile ipuleti elincane, lingasetshenziswa njengesitembu. ipuleti.Ipuleti lensimbi eligoqiwe elibandayo eliphansi kakhulu, izakhiwo zemishini, kodwa futhi lingaphansi kokucubungula, kodwa linokuqina okuhle kanye neshidi lensimbi elibandayo eligoqwe ngenxa yezinga elithile lokuqina kobunzima, ukuqina kuphansi, kodwa kungafinyelela kuboniswe kangcono, esetshenziselwa ukugoba izingcezu zentwasahlobo ezibandayo kanye nezingxenye, ngesikhathi esifanayo ngenxa yephuzu lokukhiqiza liseduze namandla aqinile, ngakho-ke akukho ukubona kusengaphambili engozini, inqubo yokusetshenziswa Lapho umthwalo udlula umthwalo ovunyelwe, izingozi zingase zenzeke.I-hot rolling igoqa ipuleti lensimbi libe yingcwecwe yensimbi encane ngokuqhathaniswa nezinga lokushisa eliphakeme.Ukugoqa okubandayo ipuleti lensimbi eligoqayo ekamelweni lokushisa.Ngokuvamile, ukugoqa okushisayo kwenziwa kuqala, bese kubanda okugoqayo.Uma ipuleti lensimbi selijiyile, lingashiswa kuphela, bese kubanda ligoqwe ngemva kokuba ligoqwe libe ipuleti elincane.Ipuleti yensimbi egoqiwe eshisayo ihlukaniswe ipuleti eliwugqinsi (ubukhulu> 4mm) kanye nepuleti elincane (ubukhulu 0.35 ~ 4mm).Ipuleti lensimbi eligoqiwe elibandayo kuphela elincanyana (ubukhulu obungu-0.2 ~ 4mm).Izinga lokushisa elinqanyuliwe lokuginqika okushisayo livamise ukuba ngu-800 ~ 900℃, bese lipholiswa ngokujwayelekile emoyeni, ngakho-ke isimo sokuginqika esishisayo silingana nokwelashwa okujwayelekile.Izinto zensimbi ezilethwa esimweni esishisayo sokugoqa zimbozwe ungqimba lwefilimu ye-oxide phezulu, ngakho zinokumelana nokugqwala okuthile.Izidingo zokugcinwa, ezokuthutha kanye nokugcinwa aziqinile njengalezo ezilethwa ngomdwebo obandayo (ukugingqika).Isibonelo, insimbi yesigaba esikhulu nesiphakathi nendawo kanye nepuleti lensimbi eliwugqinsi lingagcinwa egcekeni elivulekile lempahla noma limbozwe nge-rayon.Uma kuqhathaniswa nokuginqika okushisayo, izinto zensimbi ezigoqayo ezibandayo zinokunemba okuphezulu kobukhulu, ikhwalithi engcono yangaphezulu, ubuhhadlahhadla obuphansi kanye nezakhiwo eziphakeme zemishini.Kodwa ijwayele ukugqwala noma ukugqwala, ukupakishwa kwayo, ukugcinwa kwayo kanye nezinto zokuhamba kunezidingo eziqinile, zidinga ukugcinwa endaweni yokugcina impahla, futhi kufanele kunake izinga lokushisa nomswakama endaweni yokugcina impahla.
