Ezinsukwini ezimbalwa ezedlule, kwalayishwa izindaba ezinhle ezivela emhlanganweni wokuhlola impumelelo yesayensi nezobuchwepheshe "Wocwaningo Lwezobuchwepheshe Oluyinhloko kanye Nokusetshenziswa Kwezimboni Zokugcotshwa Kwezibuthe Zensimbi Eyinsimbi Eyinsimbi Eyinqabayo Eyirefractory" ephethwe yi-Gansu Institute of Metals: Ubuchwepheshe bubonke besayensi kanye impumelelo yezobuchwepheshe isifinyelele ezingeni elihamba phambili lamazwe ngamazwe, futhi kuyanconywa ukuthi kusheshiswe ukukhuthazwa kanye nokusetshenziswa.

I-ore yasekuqaleni yeMayini ye-Jingtieshan ye-JISCO inezinga lensimbi eliphansi, izinhlobo eziningi zamaminerali anensimbi, ubudlelwane obuyinkimbinkimbi be-symbiosis kanye nokungcola okuphezulu.Iyingxenye yensimbi ejwayelekile ye-refractory iron oxide e-China.Inqubo yendabuko yokuhlomula inezinga eliphansi lokutholwa kwensimbi kanye nezinga eliphansi lokugxila., Okuthinta izinzuzo zezomnotho zamabhizinisi, futhi ayikwazi ukuhlangabezana nezidingo ze-Jiuquan Steel zokuthuthukisa ikhwalithi nokusebenza kahle, ukuguqulwa nokuthuthukiswa, kanye nentuthuko yezinga eliphezulu.

Ukuze kuthuthukiswe ukusebenza kahle kokusetshenziswa kwezinsiza, i-Jiugang Group ibambisane ne-Northeastern University, i-Shenyang Xinbo Industrial Technology Co., Ltd. kanye namanye amayunithi ukuthuthukisa ngokuhlanganyela ubuchwepheshe bokuthosa obuyi-suspension magnetization for refractory iron oxide ore, futhi yatshala imali ekwakhiweni ukumiswa okunamandla okucutshungulwa minyaka yonke angamathani ayizigidi eziyi-1.65 ensimbi eluhlaza.Ulayini wokukhiqiza okazibuthe wokuthosa nokuhlomula waqala ukusebenza ngokusemthethweni ngoNovemba 21, 2020, futhi wazuza ukukhiqizwa nokuhambisana ngokugcwele ngoJuni 25 kulo nyaka.Uma kuqhathaniswa nenqubo yokuqala yokuhlukanisa kazibuthe enamandla, izinga lensimbi lokugxilisa ingqondo likhuphuka ngo-12%, futhi izinga lokubuyisela insimbi lenyuka ngo-26%.Umphumela ubaluleke kakhulu.

Emhlanganweni wokuhlola, ochwepheshe abayisikhombisa okuhlanganisa no-Sun Chuanyao, isazi se-Chinese Academy of Engineering, balalele imibiko, babuyekeza izinto zokwakha, futhi baxoxisana nemibuzo, egxile ezingeni lokusungula izinto ezintsha zobuchwepheshe, izinga eliphezulu lezinkomba zobuchwepheshe nezomnotho, ubunzima bobuchwepheshe kanye ubunkimbinkimbi, ukukhiqiza kabusha kobuchwepheshe kanye nokuvuthwa, Ukuqamba okusha kwezobuchwepheshe kuhlaziye ngokucophelela imiphumela ezicini eziyisithupha, okuhlanganisa indima yokuphromotha inqubekelaphambili yezobuchwepheshe bemboni kanye nokuthuthukisa ukuncintisana kwemakethe, izinzuzo zezomnotho noma zezenhlalo, kanye nemibono yokugcina yokuhlola seyenziwe.Ochwepheshe bokuhlola bakholelwa ukuthi impumelelo yesayensi nezobuchwepheshe egcwaliswe yi-Jiuquan Steel Group namanye amayunithi anezinga eliphezulu lokusungula izinto zobuchwepheshe.Umugqa wokuqala wokukhiqiza wasekhaya nowakwamanye amazwe wokuthosa okugazingiwe kanye nokuzuza okunomsebenzi wonyaka wamathani ayizigidi eziyi-1.65 wensimbi ecolekileyo unezinkomba zobuchwepheshe ezithuthukisiwe futhi waxazululwa insimbi yensimbi eyinkimbinkimbi futhi okunzima ukuyigqoka.Inkinga yokusebenzisa kahle izinsiza ikhuthaze kakhulu inqubekelaphambili yezobuchwepheshe embonini yokuhlomula insimbi.Ngenxa yobunzima bemvelo ye-ore ye-Jiuquan Iron and Steel, i-Jiuquan Iron ne-Steel Group kanye namanye amayunithi okuphothula impumelelo yephrojekthi ahlolisiswa futhi aqhutshwa, axazulule uchungechunge lwezinkinga zobuchwepheshe ekusetshenzisweni kwezimboni zokumiswa kobuchwepheshe bokugazinga uzibuthe, futhi yazuza ukusebenza okuzinzile futhi yonke inqubo yafinyelela emazingeni okukhiqiza.Yonke inqubo Ubuchwepheshe bunzima futhi buyinkimbinkimbi.Kuze kube manje, ulayini wokukhiqiza ubulokhu usebenza ngokuzinzile unyaka owodwa, ngokuvuthwa okuphezulu kwezobuchwepheshe kanye nokugcwaliseka okuphindaphindekayo, okunikeza ukwesekwa kwezobuchwepheshe ekuxazululeni kahle inkinga yokusetshenziswa kahle kwemithombo yensimbi ye-iron oxide ore, futhi kuthuthukisa ukuncintisana okuyisisekelo kwebhizinisi. .Ukukhishwa kwegesi ephuma ku-flue kufinyelela eziko zezimboni zeSifundazwe sase-Gansu kudinga ukwelashwa okujulile, okunezinzuzo ezibalulekile zezomnotho, zezenhlalakahle nezemvelo.

Kuyaqondakala ukuthi phakathi nenkathi "ye-14th Year-Five Plan", i-Jiu Steel Group, ngokusekelwe enzuzweni yayo yensiza kanye nezici zezinsiza ezizungezile, izoqhubeka nokukhuthaza amasu aqhutshwa emisha kanye namasu okuqinisekisa izinsiza, ikhuthaze ukusetshenziswa kwe-suspension magnetization. ubuchwepheshe bokugazinga, kanye nokwakha insimbi esebenza kahle, ezinzile futhi ehlukahlukene Uhlelo lwesiqinisekiso semithombo yezimbiwa luhlinzeka ngosekelo oluqinile kumabhizinisi ukuze aqinise isisekelo sezimboni zawo, abumbe kabusha izinzuzo zawo zokuncintisana, futhi abambe indawo ephakeme yentuthuko.
