Ngabe i-strip rolling mill isebenza kanjani?

Embonini yokukhiqiza insimbi, ii-i-strip rolling milliyisisetshenziswa esiyinhloko sokucubungula amabhilidi ensimbi abe yi-strip steel yemininingwane ehlukene. Inqubo yayo yokusebenza ithinta ngqo ikhwalithi nokusebenza kwe-strip steel. Kusukela ekucutshungulweni okungalungile kuya ekuqedeni, umshini wokugawula umugqa usebenzisa uchungechunge lwemisebenzi enembayo ukuze uguqule amabhilidi ensimbi ashisayo abe imikhiqizo yensimbi eyisihluthulelo ehlangabezana nezidingo zezimboni. Okulandelayo kuzoveza inqubo yayo yokusebenza kanye nobuchwepheshe obubalulekile.

Umsebenzi we-strip rolling mill uqala ngokulungiswa kwamabhilidi ensimbi. Amabhilidi ensimbi akhiqizwa inqubo eqhubekayo yokuphonsa kumele aqale ashiswe ekushiseni okuphezulu kwe-1100 ℃-1250 ℃ ukuze kuzuzwe isimo esihle sepulasitiki. Amabhilidi ensimbi afudunyezwayo athunyelwa kuyunithi egoqayo, evame ukwakhiwa izigayo eziningi ezigoqayo. Ngokugoqa okuningi, ukujiya kwamabhilidi ensimbi kuyancishiswa kancane kancane futhi kuqale kwakhiwe ngendlela ye-strip steel. Igebe le-roll namandla aginqikayo emshini wokugaya ngamunye abalwa ngokunembile futhi alungiswe ukuze kuqinisekiswe ukunemba kwe-dimensional kanye nekhwalithi yokuma yensimbi yomugqa.

Insimbi yomugqa ngemva kokugingqika ingena emshinini wokuqedela ukuze kuqhutshekwe nokucubungula. Isigayo sokuqeda siyisixhumanisi esibalulekile ekunqumeni ikhwalithi yokugcina ye-strip steel. Ifakwe amarola anembayo kanye nezinhlelo zokulawula ezithuthukile. Ingaphezulu le-roll liphathwe ngokukhethekile ukuze libe nokushelela okuphezulu kakhulu nokumelana nokugqokwa, okungaqinisekisa ukucaba nokushelela kwendawo ye-strip. Phakathi nenqubo yokugingqika, i-hydraulic AGC (isistimu yokulawula ukujiya okuzenzakalelayo) iqapha ukushuba komugqa ngesikhathi sangempela futhi ilungise ngokuzenzakalelayo igebe lokuqengqeleka ngokwenani elimisiwe, ukuze ukubekezelela ukushuba komugqa kulawulwe ngaphakathi kwebanga elincane kakhulu ukuze kuhlangatshezwane nezidingo zokunemba okuphezulu zabasebenzisi abahlukene.

Ukwengeza, ukuze uvimbele umugqa ukuthi ungaphumi, omise okwegagasi nezinye iziphambeko phakathi nenqubo yokugingqika, umshini wokugaya umugqa ubuye ufakwe uhlelo lokulawula ukuma kwepuleti. Ngokuthola ukusabalalisa okushubile endaweni ngayinye endaweni ephambanayo yomugqa, isistimu ilungisa ngokuzenzakalelayo ukuguquguquka nokuthambekela komqulu ukuze yenze ukunwetshwa komugqa kuyunifomu yokuqondisa kobubanzi futhi kuqinisekise ukwakheka kwepuleti elihle. Izinga lokushisa lomugqa ogoqiwe livamise ukuthi licishe libe ngu-800℃, futhi lidinga ukungena ohlelweni lokupholisa ngokushesha ukuze liphole ngokushesha. Izinga lokupholisa nokufana kokupholisa kunethonya elibalulekile esakhiweni senhlangano kanye nezakhiwo zemishini zomucu. Ngokulawula inani lamanzi okupholisa kanye nendlela yokufafaza kwamanzi, umugqa ungathola i-microstructure efanelekile kanye nezakhiwo zemishini.

Ekugcineni, umugqa opholile ugoqwa ube ikhoyili yikhoyili ukuze kuqedelwe yonke inqubo yokugingqa. Izigayo zesimanje eziginqayo ziphinde zihlanganise amasistimu okuthola nokuqapha okuzenzakalelayo, angathola ikhwalithi yendawo ephezulu, ukunemba kobukhulu kanye neminye imingcele yomugqa ngesikhathi sangempela. Uma inkinga isitholakele, i-alamu izokhishwa ngokushesha futhi ukulungiswa kuzokwenziwa ukuze kuqinisekiswe ikhwalithi yomkhiqizo ezinzile nethembekile.

Ama-strip rolling Millssebeyithuluzi elibalulekile nelibalulekile ekukhiqizeni insimbi ngesakhiwo sazo esinembile, uhlelo lokulawula oluthuthukisiwe kanye nokugeleza kwenqubo yesayensi. Bayaqhubeka nokuhlinzeka ngemikhiqizo yekhwalithi ephezulu yezimboni eziningi ezifana nezokwakha, izimoto, nezinto zikagesi zasendlini, futhi bakhuthaze intuthuko eqhubekayo yomkhakha wesimanje.
