Ngezinguquko eziqhubekayo emkhakheni wezimboni zama-ripples, isithando somlilo se-DC esinezinzuzo eziyingqayizivele kanye namathemba abanzi entuthuko, kancane kancane ivela njengenkanyezi ekhanyayo ukuhola inqubekelaphambili yezobuchwepheshe bemboni.
Njengamanje embonini ye-metallurgical ekusetshenzisweni kwesithando sokushisa kwamaminerali e-DC kusukela ngawo-1970 kwaqala ukuthuthukisa ubuchwepheshe obusha. Ukuqiniswa kwe-arc yomlilo we-DC, ukugxila kwamandla, ukusebenza kahle kokushisa okuphezulu, nokusetshenziswa kwamandla okuphansi, ukusetshenziswa okuncane kwama-electrode, umsindo ophansi wokusebenza, ukukhiqiza okuphezulu.
Kwamanye amazwe, ngo-1984 eNingizimu Afrika yakhe umthamo 40MVA high carbon ferrochrome ngqo isithando somlilo wamanje. Iminyaka engama-70-80 yaseShayina i-1800-8000kvA i-ferrosilicon, i-silicon yezimboni, i-silicomanganese, i-ferrochrome, isithando somlilo esiqinile se-DC amaminerali okushisa (i-electrode eyodwa ephansi) kanye nesithando somlilo se-DC steelmaking sizuze isipiliyoni esiyimpumelelo, eminyakeni yamuva nje, i-China yakhiwe futhi yafakwa ngaphakathi. ukukhiqizwa kwesithando somlilo se-DC ikakhulukazi:
12500-33000kvA I-Silicon-Manganese DC Mineral Heat Furnace(ama-electrode ama-4)
I-12500-16500kvA I-Silicon Ephakeme ye-DC Mineral Heat Furnace(ama-electrode ama-4)
I-12500kvA I-Silicon Barium DC Isithando sokushisa esineMineral (ama-electrode ama-4)
12500kvA Silicon Zirconium DC Mineral Heat Furnace(ama-electrode ama-4)
10000-16000kw Industrial Silicon DC Mineral Heat Furnace(4 electrodes)
9000kw Ferrochrome DC Mineral Heat Furnace (4 electrodes)
30000kw Titanium Slag DC Mineral Heat Furnace(1 base electrode)
Ukuthuthukiswa kweziko lokuncibilika kwe-DC kumelela inqubekelaphambili enkulu ekuqhubekeleni phambili kwezobuchwepheshe. Uma kuqhathaniswa nesithando somlilo esivamile se-AC amaminerali, izinzuzo zaso zisobala. Mayelana nokusebenza kahle kwamandla, isithando somlilo se-DC sizoguqulwa sibe amandla okushisa athuthukisiwe kakhulu. Izibalo zangempela zibonisa ukuthi izinga layo lokusebenzisa amandla liphakeme cishe ngo-20% kunesithando somlilo esivamile, okunciphisa kakhulu ukulahlekelwa kwamandla futhi kufake umfutho oqinile wokunciphisa izindleko zokukhiqiza nokuthuthukisa ukusebenza kahle komnotho. Ngesikhathi esifanayo, isithando somlilo sokushisa amaminerali e-DC sibonisa ukuzinza okuhle kakhulu nokulawula ngesikhathi sokusebenza, futhi iyakwazi ukulawula ngokunembile izimo zokusabela esithandweni somlilo, ngaleyo ndlela iqinisekise ukuthuthukiswa okuqhubekayo kwekhwalithi yomkhiqizo kanye nokwanda okuqhubekayo kokukhiqiza.
Ngokusho kwedatha ekhona, ukuqhathanisa okuphelele kwezinkomba zokukhiqiza kwesithando somlilo se-DC nesithando somlilo se-AC, ukuphuma kwesithando somlilo se-DC, ukusetshenziswa kwamandla nezinye izinkomba zingcono kakhulu kunesithando somlilo se-AC, ukwanda kokuphumayo kungenxa yokwehliswa kokusetshenziswa kwamandla okuncibilika. kanye nokuthuthukiswa kwesici samandla somphumela ohlangene wemiphumela.
Njengamanje isithando somlilo se-DC 4 electrode, ama-electrode angu-6 nokunye ukuthuthukiswa kobuchwepheshe be-multi-electrode, okubonisa kakhulu izinzuzo ezisobala ze-DC mineral smelting ferroalloys, kuwumkhuba ongenakugwemeka wokonga amandla kanye nesithando somlilo esikhulu samaminerali. Ngaphezu kwalokho, ukuhlanganiswa kobuchwepheshe obukhaliphile kwenza i-DC smelting furnace automation degree ibe ngcono kakhulu, ukusebenza kulula futhi kusebenza kahle, ngoba ukukhiqizwa kwebhizinisi kulethe ukunethezeka okukhulu.
Ngesikhathi esifanayo nomqondo wokuvikelwa kwemvelo ngokujulile, isithando somlilo se-DC siphinde samukele ngenkuthalo umkhuba oluhlaza wezikhathi. Idatha efanelekile ibonisa ukuthi isithando somlilo se-DC ekongeni amandla nokusebenza kokunciphisa ukungcola kuhle kakhulu, ukukhishwa okungcolile kwehliswe kakhulu, ngoba intuthuko esimeme ibe nomthelela emandleni.
Ukubuyekeza umlando wokuthuthuka we-DC melting furnace, asikwazi ukuzibamba ngaphandle kokumangala ngokusebenza kanzima nokuhlakanipha okucwebezelayo kwabacwaningi nonjiniyela. Kusukela egciwaneni lomqondo wokuqala, kuya ekuthuthukisweni okuqhubekayo kanye nokwenza kahle kobuchwepheshe, zonke izinyathelo zokujuluka nokuhlakanipha kwabo. Isibonelo, lapho kwakhiwa isithando somlilo esincibilikisa i-DC, ibhizinisi lenze ngempumelelo amapharamitha kagesi nezinto zokwakha kanye nesakhiwo ngemuva kokuhlolwa nokuthuthukiswa okuningi, ukuze umzimba wesithando somlilo ukwazi ukumelana kangcono nezimo ezimbi kakhulu ezifana nokushisa okuphezulu nokucindezela okukhulu, futhi Ngesikhathi esifanayo, ukusebenza kwama-electrode nezinye izingxenye ezibalulekile nakho kuye kwathuthukiswa kakhulu.
Uma sibheka phambili, isithando somlilo samaminerali e-DC kulindeleke ukuthi sizuze impumelelo enkulu nentuthuko:
Okokuqala, ukuqanjwa okusha kwezobuchwepheshe kuzothuthukisa ukusebenza kahle kwamandla kanye nokuzinza kwesithando somlilo se-DC ukuze kuthuthukiswe, kusize amabhizinisi ukwehlisa izindleko zokukhiqiza kanye nokwenza ngcono ukuncintisana kwemakethe.
Okwesibili, ukuthuthukiswa kwesithando sokushisa amaminerali e-DC kuzosebenzisa ubuhlakani bokufakelwa, idatha enkulu kanye nezinye izindlela zobuchwepheshe ezihlakaniphile zokubona ukuqapha kwesikhathi sangempela nokulawula okuzenzakalelayo kwezimo zesithando somlilo, ukusheshisa ukusetshenziswa kwemishini eyisiza ehlakaniphile, kuhlanganise ne-AI ehlakaniphile. ukucwenga, irobhothi leso lepulaki elivulekile, irobhothi le-electrode elixhumayo, umshini wokupompa okuzenzakalelayo, irobhothi elihlolayo, idivayisi yokucabanga ngezinga lokushisa eliphezulu esithandweni, idivayisi yokuhlanza okuzenzakalelayo, isistimu yokusakaza eqhubekayo, nolunye uhlelo lokusebenza lwemishini eyisiza ethuthukisiwe, ukuze Kuthuthukiswe ukusebenza kahle kokukhiqiza, ukunciphisa amandla ukusetshenziswa, ukuthuthukisa ikhwalithi yomkhiqizo, futhi uqaphele ubuhlakani kanye nokutshala kwesistimu yokukhiqiza.
Ngaphezu kwalokho, izinkambu zokufaka isicelo ze-DC melting furnace nazo zizokwandiswa, ngaphezu kokudlala indima ebalulekile embonini ye-metallurgical, kulindeleke ukuthi zisetshenziswe kabanzi embonini yamakhemikhali, izinto zokwakha kanye neminye imikhakha, kube nomthelela ekuthuthukisweni nasekuthuthukisweni. yezimboni ezengeziwe.
Ukusetshenziswa okuphumelelayo kwe-DC esithandweni sokushisa kwamaminerali kulethe izinzuzo ezibalulekile namathuba okuthuthukiswa embonini yokuncibilikisa. Ngokuqhubeka okusha nokuthuthuka kwezobuchwepheshe, sinesizathu sokukholelwa ukuthi i-DC izoqhubeka nokubamba iqhaza elibalulekile esikhathini esizayo, ukukhuthaza ukuthuthukiswa okuqhubekayo kanye nenqubekelaphambili yobuchwepheshe besithando sokushisa amaminerali, ubuchwepheshe bokuncibilika ukuze kuthuthukiswe futhi kunikeze indawo engenamkhawulo yokuthuthukiswa. yemikhiqizo emisha, ukuze imboni yezimboni ilethe umbono obanzi kanye nentuthuko esimeme yekusasa.
Ngamafuphi, isithando somlilo se-DC esinezinzuzo eziyingqayizivele namathemba abanzi entuthuko, sizoqhubeka nokubamba iqhaza elibalulekile emkhakheni wezimboni wesikhathi esizayo, futhi senze igalelo elikhulu ekuqhubekeleni phambili kwezimboni nentuthuko esimeme. Sibheke ngabomvu emisha eyengeziwe kanye nempumelelo yokukhuthaza ubuchwepheshe besithando sokushisa samaminerali e-DC bufinyelele phezulu okusha!
