Kuyini ukugoqwa okushisayo, yini ukugoqwa okubandayo, kanye nomehluko phakathi kwalokhu okubili?

 

1. Ukujikijela Okushisayo
Ama-slabs okuphonsa aqhubekayo noma ama-slabs okuqala okugoqa njengezinto zokusetshenziswa, afudunyezwa ngesithando sokushisa esinyathelweni, ukuncishiswa kwamanzi ngomfutho ophezulu ku-roughing mill, izinto zokugoqa ngokusika ikhanda, umsila, bese zifakwa ku-finning mill, ukuqaliswa kokugoqa okulawulwa yikhompyutha, ukugoqa kokugcina okungemva kokupholisa ukugeleza kwe-laminar (izinga lokupholisa elilawulwa yikhompyutha) kanye nokugoqa komshini wokugoqa, kuba ama-hair rolls aqondile. Ikhanda nomsila we-coil yezinwele eziqondile kuvame ukuba nolimi nomsila wenhlanzi, ukujiya, ukunemba kobubanzi kuphansi, kuvame ukuba nomkhawulo ofana negagasi, umkhawulo ogoqiwe, umbhoshongo kanye nezinye izinkinga. Isisindo sawo sinzima, ububanzi bangaphakathi be-coil yensimbi bungu-760mm. (Imboni yokwenza amapayipi ejwayelekile ithanda ukusebenzisa.) I-coil yezinwele eziqondile ngokusika ikhanda, umsila, umkhawulo wokusika kanye nokuqondisa okungaphezu kweyodwa, ukulinganisa kanye nokunye ukucubungula komugqa wokuqedela, bese usika ipuleti noma ukuphinda ugoqe, okuzoba: ipuleti yensimbi egoqiwe eshisayo, ama-coil ensimbi agoqiwe ayisicaba, i-strip yokusika ende kanye neminye imikhiqizo. Ama-coil okuqeda agoqiwe ashisayo uma u-pickling esusa isikhumba se-oxide bese ugcotshwa ku-hot rolled pickled coil. Isithombe esingezansi sibonisaikhoyili egoqiwe eshisayo.

 

2. Okugoqiwe Okubandayo
Amakhoyili ensimbi asongwe ngokushisa njengezinto zokusetshenziswa, ngemva kokukhuhla ukuze kususwe isikhumba se-oxide ukuze kugoqwe kubanda, umkhiqizo oqediwe wevolumu eqinile egoqwe, ngenxa yokuguquka okuqhubekayo kokubanda okubangelwa ukuqina okubandayo kwevolumu eqinile egoqwe, amandla, ubulukhuni, ukuqina kanye nokwehla kwezinkomba zepulasitiki, ukuwohloka kokusebenza kokunyathela, kungasetshenziswa kuphela ekuguqulweni okulula kwezingxenye. Ikhoyili eqinile egoqwe ingasetshenziswa njengezinto zokusetshenziswa zesitshalo se-galvanizing esishisayo, ngoba iyunithi ye-galvanizing eshisayo isethwe ngomugqa wokunamathisela. Isisindo sekhoyili eqinile egoqwe ngokuvamile singamathani ayi-6 ~ 13.5, ububanzi bangaphakathi bekhoyili bungu-610mm. Ipuleti eligoqwe ngokubandayo elijwayelekile, ikhoyili kufanele ibe yi-annealing eqhubekayo (iyunithi ye-CAPL) noma ukwelashwa kwe-hooded furnace de-annealing, ukuze kuqedwe ukuqina nokubanda kanye nokucindezeleka kokugoqwa, ukuze kufezwe izakhiwo zemishini ezichazwe ezinkomba ezijwayelekile. Ikhwalithi yobuso bepuleti lensimbi eligoqwe ngokubandayo, ukubukeka, ukunemba kobukhulu kungcono kunepuleti eligoqwe ngokushisayo. Isithombe esilandelayo sibonisaikhoyili egoqiwe ebandayo.

 

Umehluko omkhulu phakathiinsimbi egoqiwe ebandayo vs insimbi egoqiwe eshisayokulele kubuchwepheshe bokucubungula, ububanzi bokusetshenziswa, izakhiwo zemishini kanye nekhwalithi yobuso, kanye nomehluko wamanani. Okulandelayo yisingeniso esinemininingwane:
Ukucutshungulwa. Ukugoqa okushisayo kwenziwa emazingeni okushisa aphezulu, kuyilapho ukugoqa okubandayo kwenziwa emazingeni okushisa egumbi. Ukugoqa okushisayo kugoqa ngaphezu kwezinga lokushisa lokukristala, kuyilapho ukugoqa okubandayo kugoqa ngaphansi kwezinga lokushisa lokukristala.

 
Izicelo. Insimbi egoqwe ngokushisa isetshenziswa kakhulu ezakhiweni zensimbi noma ezingxenyeni zemishini, okuhlanganisa ukwakhiwa kwamabhuloho, kuyilapho insimbi egoqwe ngokushisa isetshenziswa kakhulu embonini yezimoto noma ezintweni ezincane zikagesi, imishini yokuwasha, iziqandisi, njll., okuhlanganisa nezinto zokwakha.

 
Izakhiwo zemishini. Izakhiwo zemishini ezigoqiwe ngokubandayo zivame ukuba ngcono kunezigoqiwe ngokubandayo, ngoba inqubo yokugoqiwa ngokubandayo ikhiqiza umphumela wokuqina noma ukuqina okubandayo, okuholela ekubeni ubulukhuni kanye namandla ephepha eligoqiwe ngokubandayo kuphakeme, kodwa ukuqina kuphansi, kuyilapho izimfanelo zemishini zephepha eligoqiwe ngokushisayo zincane kakhulu kunephepha eligoqiwe ngokubandayo, kodwa zinokuqina kanye nokuguquguquka okungcono.

 
Ikhwalithi yobuso. Ikhwalithi yesakhiwo sobuso sensimbi egoqiwe ebandayo izoba ngcono kunensimbi egoqiwe eshisayo, imikhiqizo egoqiwe ebandayo iqinile futhi ayinamatheli kakhulu, kuyilapho imikhiqizo egoqiwe eshisayo inobuso obuqinile nobunobume.

 
Ubukhulu bencazelo. Ama-coil aqoqwe ngokubandayo avame ukuba mancane kune-hot rolled coils, kanti ubukhulu bama-coil aqoqwe ngokubandayo busukela kumamilimitha angu-0.3 kuya kwangu-3.5, kanti ama-hot rolled coils asukela kumamilimitha angu-1.2 kuya kwangu-25.4.

Intengo: Ngokuvamile, i-cold roll ibiza kancane kune-hot roll. Lokhu kungenxa yokuthi i-cold roll idinga ukusetshenziswa kwemishini yokucubungula eyinkimbinkimbi kakhulu kanye nobuchwepheshe benqubo obuyinkimbinkimbi kakhulu, futhi ukwelashwa kwe-cold roll kungathola umphumela ongcono wokwelashwa kwendawo, ngakho-ke ikhwalithi yemikhiqizo e-cold roll ngokuvamile iphakeme, intengo iphakeme ngokufanayo. Ngaphezu kwalokho, insimbi e-cold roll enqubweni yokukhiqiza idinga ubuchwepheshe bokucubungula obuqinile kanye nobunzima bokucubungula obuphezulu, imishini yokukhiqiza, ama-roll kanye neminye imishini iphakeme, okuzoholela nasekukhuphukeni kwezindleko zokukhiqiza.
