Ngokwesimo sokuginqika somshini wokugoqa, inqubo yokukhiqiza yesigayo sensimbi yeshidi ingahlukaniswa ibe izinhlobo ezimbili: inqubo yepuleti lensimbi egoqelwe eshisayo kanye nenqubo yepuleti lensimbi egoqelwe ngokubanda. Phakathi kwazo, inqubo ye-hot-rolled medium plate, ipuleti eliwugqinsi kanye nepuleti elincane kubunjiniyela be-metallurgical iyafana. Ngokuvamile, ihamba ngezinyathelo eziyinhloko zokulungiselela impahla eluhlaza - ukushisa - ukugoqa - ukulungiswa kwesimo esishisayo - ukupholisa - ukutholwa kwamaphutha - ukusika okuwolintshi, okuchazwa kanje.
I-slab ithuthelwa endaweni yokugcina impahla ngesitshalo esiqhubekayo sokuphonsa noma esiqhakazayo, yehliswa ukhreyini futhi igcinwe endaweni yokugcina impahla (i-silicon steel slab ithunyelwa endaweni yokugcina impahla ye-silicon steel billet ngeloli lokulondoloza ukushisa, futhi yehliselwa ekushiseni. isithando somlilo nge-crane , Ngemva kokuhlanza okungeziwe, sisafakwa esithandweni somlilo ukuze sisongwe). Ngesikhathi sokukhiqizwa kobunjiniyela be-metallurgical, ama-slabs aphakanyiselwa emzileni ngamunye ngama-cranes, bese ephushwa esithandweni ukuze ashise ngaphambi kokuba ahanjiswe esithandweni sokushisa. Kunezinhlobo ezimbili zezithando zokushisa: uhlobo oluqhubekayo noma uhlobo lwe-flat-section. Ipuleti elishisayo lithuthwa liyiswe kusikali esime mpo ngethrekhi yokukhiphayo ukuze kukhishwe isikali esiyinhloko. Bese ufaka izigayo zokuqala nesesibili eziphakeme ezimbili, ugoqe uye phambili amaphasi amathathu noma amahlanu, bese ufaka izigayo zesithathu nesine ezine-high-high roughing ukuze uginqike ngokuqhubekayo, ugingqa iphasi elilodwa. Phakathi nenqubo yokugoqa, amanzi anengcindezi ephezulu asetshenziselwa ukususa isikali se-oxide, futhi ubukhulu obujwayelekile bugoqwe bufinyelele ku-20 ~ 40mm. Ngemva kwesigayo sesine esigayayo, ukujiya, ububanzi nezinga lokushisa kuyalinganiswa. Ngemuva kwalokho, ngaphambi kokuthunyelwa kusuka etafuleni le-roller kuya emshinini wokuqeda, inhloko ye-shear endizayo (nomsila nayo inganqunywa) yenziwa kuqala, bese ukugoqa okuqhubekayo kwenziwa ngokusebenzisa isigayo sokuqeda ezine-high. Ngemva kokugingqika okuqhubekayo, umugqa wensimbi upholiswa ngokugeleza kwe-laminar futhi ungene ku-downcoiler ukuze ugoqelwe kumakhoyili ensimbi agoqelwe ashisayo, futhi inqubo yokugingqa iyaqedwa. Khona-ke, amakhoyili athunyelwa endaweni yokugaya ebandayo, ishidi lensimbi ye-silicon kanye nohlelo lokuqeda lwefektri yethu ngokuvumelana nokusetshenziswa okuhlukene kwekhoyili yensimbi. Inhloso yokuqedela ubunjiniyela be-metallurgical ukulungisa ukuma, ukuthuthukisa izakhiwo zemishini kanye nokuthuthukisa ukuma kwendawo. Ngokuvamile, kunemigqa yokucubungula emihlanu, ehlanganisa imigqa emithathu yokucubungula enqamulayo, ulayini wokucubungula owodwa wokusika, kanye nomugqa owodwa wokucubungula oshisayo. Ngemva kokuqeda, Ipakishwe ngezinhlobonhlobo futhi ilungele ukuthunyelwa.
Yonke inqubo yokugoqa yomugqa wokukhiqiza i-othomathikhi ngokugcwele. Okungukuthi, kusukela kuthebula le-feeding roller - ukushisisa isithando somlilo - ukugoqa kwesigayo esiqhakazayo - ukupholisa kwe-mill rolling laminar - ikhoyili ikhoyili - kuze kube iphuzu eliphindwe kabili leketango lokuthutha ikhoyili yensimbi, yonke inqubo yokukhiqiza iqukethe inqubo eyodwa. Ikhompuyutha yokulawula (i-SCC) kanye namakhompuyutha amathathu okulawula okuqondile kwedijithali (i-DDC) yokulawula okuzenzakalelayo.
