Mayelana nokushisa okugoqiwe
Uma kuqhathaniswa nokuginqika okubandayo, ukugoqa okushisayo kugingqika ngaphansi kwezinga lokushisa elicwebezelayo, futhi ukugoqa okushisayo kugingqika ngaphezu kwezinga lokushisa lekristalu.
Eyaziwa nangokuthi i-hot plate, ipuleti eligoqiwe elishisayo.I-hot-rolled slab yenziwe nge-casting slab eqhubekayo noma i-pre-rolled slab njengempahla eluhlaza, eshiswa esithandweni sokushisa esinyathelayo, ehliswe ngamanzi anomfutho ophezulu, bese ingena emshinini wokugoqa.Izinto ezigoqayo zingena emshinini wokuqedela wokulawula ikhompuyutha ngemva kokusika ikhanda nomsila.Ngemva kokuginqika, ngemva kokugingqika kokugcina, ipholiswa ngokugeleza kwe-laminar (isivinini sokupholisa esilawulwa ngekhompuyutha, futhi ihlanganiswe ibe amakhoyili aqondile ngamakhoyili.
Inzuzo
(1) Ukuginqika okushisayo kunganciphisa kakhulu ukusetshenziswa kwamandla futhi kunciphise izindleko.Ngesikhathi sokushisa okushisayo, insimbi ine-plasticity ephezulu kanye nokumelana okuphansi kwe-deformation, okunciphisa kakhulu ukusetshenziswa kwamandla kwe-deformation yensimbi.
(2) Ukugoqa okushisayo kungathuthukisa izakhiwo zokucubungula zezinsimbi nama-alloys.Ngisho noma ama-as-cast amahlamvu ama-coarse ephukile, ukuqhekeka kuyaphulukiswa ngokusobala, amaphutha okuphonsa ayancishiswa noma aqedwe, futhi isakhiwo se-as-cast siguqulwa sibe isakhiwo esikhubazekile, esithuthukisa ukusebenza kokucubungula kwe-alloy.
(3) Ukugoqa okushisayo kuvame ukuthatha ama-ingots ensimbi amakhulu kanye nezilinganiso ezinkulu zokunciphisa ukugingqika, okungathuthukisi nje ukusebenza kahle kokukhiqiza, kodwa futhi kudala izimo zokwandisa isivinini sokugingqa nokuqaphela ukuqhubeka nokuzenzakalela kwenqubo yokugoqa.
Ukwahlukanisa
Ipuleti lensimbi eligoqiwe elishisayo lihlukaniswe ngensimbi yesakhiwo, insimbi ye-carbon ephansi kanye nensimbi yebhodlela lokushisela.Ishidi lensimbi eligoqiwe elishisayo linobulukhuni obuphansi, ukucubungula okulula kanye ne-ductility enhle.Amashidi ensimbi agoqelwe ngokushisayo anamandla aphansi uma kuqhathaniswa nekhwalithi ephezulu ephansi (i-oxidation ephansi/ isiphetho sokuqeda), kodwa ipulasitiki enhle.Ngokuvamile, amapuleti aphakathi nendawo nasindayo kanye namapuleti agoqelwe ngokubanda anamandla aphezulu, ubulukhuni obuphezulu kanye nokuqedwa okuphezulu kwendawo.Ngokuvamile amapuleti amancane futhi angasetshenziswa njengamapuleti okugxiviza.
Ubukhulu
Usayizi wepuleti yensimbi kufanele uhlangabezane nezidingo zethebula "Ubukhulu kanye Nemininingwane Yamapuleti Ensimbi Agoqwe Okushisayo (okukhishwe ku-GB/T709-2006)".
Ububanzi bepuleti lensimbi nakho kungaba yinoma yimuphi usayizi ongu-50mm noma ukuphindaphinda okungu-10mm, futhi ubude bepuleti lensimbi bungaba yinoma yimuphi usayizi ongu-100mm noma ukuphindaphinda okungu-50mm, kodwa ubude obuncane bepuleti lensimbi elinogqinsi olungaphansi. kunanoma okulingana nobukhulu bulingana no-4mm futhi bungekho ngaphansi kuka-1.2m, futhi ukujiya kungaphezu kuka-4mm.Ubude obuncane bepuleti lensimbi abukho ngaphansi kuka-2m.Ngokwezidingo, ubukhulu bepuleti lensimbi bungaphansi kuka-30mm, kanti isikhathi sokujiya singaba ngu-0.5mm.Ngokwezidingo, ngemva kokuxoxisana phakathi komphakeli nomthengi, ezinye izicaciso zamapuleti ensimbi nezinsimbi zensimbi zinganikezwa.
