Ezinsukwini ezimbalwa ezedlule, kwalayishwa izindaba ezinhle ezivela emhlanganweni wokuhlola impumelelo yesayensi nezobuchwepheshe "Wocwaningo Lwezobuchwepheshe Oluyinhloko kanye Nokusetshenziswa Kwezimboni Zokugcotshwa Kwezibuthe Ze-Iron Oxide Ore Refractory Refractory Iron Oxide Ore Suspension Magnetization Roasting" ephethwe yi-Gansu Institute of Metals: The general technology of the science and impumelelo yezobuchwepheshe isifinyelele ezingeni elihamba phambili lamazwe ngamazwe, futhi kuyanconywa ukuthi kusheshiswe ukukhuthazwa 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 lokugxilisa ingqondo., 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 bezobuchwepheshe kanye ubunkimbinkimbi, ukukhiqizwa 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 zomphakathi, kanye nemibono yokugcina yokuhlola iye yakhiwe.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 ngokucutshungulwa minyaka yonke kwamathani ayizigidi eziyi-1.65 wensimbi ecolekileyo unezinkomba zobuchwepheshe ezithuthukile 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, umugqa wokukhiqiza ubulokhu usebenza ngokuzinzile unyaka owodwa, ngokuvuthwa okuphezulu kwezobuchwepheshe kanye nokugcwaliseka okuphindaphindekayo, okunikeza ukwesekwa kobuchwepheshe ekuxazululeni kahle inkinga yokusetshenziswa kahle kwemithombo yensimbi ye-iron oxide ore, futhi kuthuthukisa ukuncintisana okuyisisekelo kwebhizinisi. .Ukukhishwa kwegesi ephuma ku-flue kufinyelela eziko ezimbonini zesiFundazwe sase-Gansu kudinga ukwelashwa okujulile, okunezinzuzo ezibalulekile kwezomnotho, kwezenhlalo nezemvelo.

Kuyaqondakala ukuthi phakathi nenkathi "ye-14th Five-Year 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-magnetization yokumiswa. 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.
