Kuyini ukugoqa okushisayo, yini okugoqiwe okubandayo, kanye nomehluko phakathi kwakho kokubili?

 

1. I-Hot Rolling
Ama-slabs aqhubekayo okuphonsa noma ama-slabs okuqala njengezinto zokusetshenziswa, ezishiswa ngesinyathelo sokushisa isithando somlilo, i-high-pressure water dephosphorization emshinini wokugaya, izinto eziqinile ngokusika ikhanda, umsila, bese ufaka emshinini wokuqeda, ukuqaliswa kokugoqa okulawulwa yikhompyutha, ukugoqa kokugcina okungemva kokupholisa kwe-laminar ukugeleza kokupholisa (i-cooling rolling eqondile) umshini wokupholisa izinwele, ukulawulwa kwe-cooling eqondile. Ikhanda kanye nomsila wekhoyili wezinwele eziqondile ngokuvamile ulimi nomsila we-fishtail, ukushuba, ukunemba kobubanzi kumpofu, kuvame ukuba nonqenqema olumise okwegagasi, unqenqema olugoqiwe, umbhoshongo nezinye iziphambeko. Isisindo somthamo wayo sikhulu, ububanzi bangaphakathi bekhoyili yensimbi bungama-760mm. (Imboni ejwayelekile yokwenza amapayipi ithanda ukusebenzisa.) Ikhoyili yezinwele eziqondile ngokusika ikhanda, umsila, unqenqema lokusika kanye nokuqondisa okungaphezu kokukodwa, ukulevelisa nokunye ukucubungula umugqa wokuqedela, bese usika ipuleti noma ukugoqa kabusha, okusho ukuthi kuzoba: ipuleti lensimbi eligoqiwe elishisayo, amakhoyili ensimbi ashisayo ayisicaba, umugqa wokusika ubude neminye imikhiqizo. Amakhoyili okuqeda agoqwe ashisayo uma i- pickling isusa isikhumba se-oxide futhi igcotshwe yikhoyili egoqiwe eshisayo. Umfanekiso ongezansi ukhombisaikhoyili egoqiwe eshisayo.

 

2. Abandayo Rolled
Amakhoyili ensimbi agoqwe ashisayo njengezinto zokusetshenziswa, ngemva kokukhetha ukususa isikhumba se-oxide ukuze sigoqeke, umkhiqizo osuphelile wevolumu eqinile egoqiwe, ngenxa yokuguquka okubandayo okubangelwa ukuqina okubandayo komthamo oqinile ogoqiwe wamandla, ukuqina, ukuqina kanye nezinkomba zepulasitiki ziyancipha, ukuwohloka kokusebenza kwesitembu, kungasetshenziswa kuphela ukuguqulwa okulula kwezingxenye. Ikhoyili eqinile egoqiwe ingasetshenziswa njengezinto ezisetshenziswayo esitshalweni sokuthela amadiphu ashisayo, ngoba i-hot-dip galvanizing unit yakhiwe ngentambo yokudonsa. Isisindo sekhoyili egoqiwe ngokuvamile singamathani angu-6 ~ 13.5, ububanzi bangaphakathi bekhoyili bungama-610mm. ipuleti eligoqiwe elibandayo elijwayelekile, ikhoyili kufanele ibe yi-continuous annealing (CAPL unit) noma i-hooded furnace de-annealing treatment, ukuze kuqedwe ukuqina okubandayo kanye nokucindezeleka okugoqayo, ukuze kuzuzwe izakhiwo zemishini ezibalulwe ezinkomba ezijwayelekile. Ikhwalithi yobuso bepuleti eligoqiwe elibandayo, ukubukeka, ukunemba kobukhulu kungcono kunepuleti eligoqiwe elishisayo. Umfanekiso olandelayo ukhombisaikhoyili egoqiwe ebandayo.

 

Umehluko omkhulu phakathiebandayo iginqika vs insimbi egoqiwe eshisayoilele kubuchwepheshe bokucubungula, ububanzi bokusebenza, izakhiwo zemishini kanye nekhwalithi yendawo, kanye nokwehluka kwamanani. Okulandelayo yisingeniso esinemininingwane:
Iyacubungula. Ukugoqa okushisayo kwenziwa emazingeni okushisa aphezulu, kuyilapho ukugoqa okubandayo kwenziwa ekamelweni lokushisa. I-Hot rolling igingqika ngaphezu kwezinga lokushisa elicwebezelayo, kuyilapho ukugoqa okubandayo kwehlela ngaphansi kwezinga lokushisa elicwebezelayo.

 
Izinhlelo zokusebenza. Insimbi egoqiwe eshisayo isetshenziswa kakhulu ezakhiweni zensimbi noma ezingxenyeni zemishini, okuhlanganisa ukwakhiwa kwebhuloho, kuyilapho insimbi egoqiwe ebandayo isetshenziswa kakhulu embonini yezimoto noma izinto zikagesi ezincane, imishini yokuwasha, iziqandisi, njll., okuhlanganisa izinto zokwakha.

 
Izakhiwo zemishini. Izakhiwo zomshini ezigoqiwe ezibandayo zivame ukuba ngcono kunokushisa okugoqiwe, ngoba inqubo yokugoqa ebandayo ikhiqiza umphumela oqinile noma ukuqina okubandayo, okuholela ekubanda kweshidi eligoqiwe ubulukhuni namandla aphezulu, kodwa ukuqina kuphansi, kuyilapho izakhiwo zemishini zeshidi eligoqiwe lincane kakhulu kuneshidi eligoqiwe elibandayo, kodwa linokuqina okungcono kanye ne-ductility.

 
Ikhwalithi yobuso. Ikhwalithi yesakhiwo esingaphezulu sensimbi egoqiwe ebandayo izoba ngcono kunensimbi egoqiwe eshisayo, imikhiqizo egoqiwe ebandayo iba lukhuni futhi incane i-ductile, kuyilapho imikhiqizo egoqiwe eshisayo inobuso obuqinile, obuthungwe.

 
Ukujiya kokucaciswa. Amakhoyili aqandayo abandayo avamise ukuba mancane kunamakhoyili ashisayo, anogqinsi lwamakhoyili abandayo asuka ku-0.3 kuya ku-3.5 millimeters, kanti amakhoyili ashisayo asuka ku-1.2 kuya ku-25.4 amamilimitha.

Inani:Imvamisa, ukugoqa okubandayo kuyabiza kakhulu kunokugoqwa okushisayo. Lokhu kungenxa yokuthi ukugoqa okubandayo kudinga ukusetshenziswa kwemishini yokucubungula eyinkimbinkimbi kanye nobuchwepheshe benqubo obuyinkimbinkimbi, futhi ukwelashwa okugoqa okubandayo kungathola umphumela ongcono wokwelapha ongaphezulu, ngakho ikhwalithi yemikhiqizo egoqiwe ebandayo ngokuvamile iphakeme, intengo iphakeme ngokuhambisanayo. Ngaphezu kwalokho, insimbi egoqiwe ebandayo ohlelweni lokukhiqiza idinga ubuchwepheshe bokucubungula obuqinile kanye nobunzima bokucubungula okuphezulu, imishini yokukhiqiza, imiqulu kanye nezinye izidingo zemishini ziphakeme, okuzoholela ekukhuphukeni kwezindleko zokukhiqiza.
