Nekuchinja kuri kuramba kuchiitika mumunda wemaindasitiri, DC melting choto ine zvayakanakira zvakasiyana uye mikana yakakura yekukura, iri kubuda zvishoma nezvishoma senyeredzi yakajeka kutungamira kufambira mberi kwetekinoroji muindasitiri.
Pari zvino muindasitiri yesimbi, kushandiswa kwechoto cheDC mineral heat furnace kwave kuripo kubva kuma1970. Kugadzikana kwearc furnace yeDC, kuwanda kwesimba, kushanda zvakanaka kwekupisa, kushandiswa kwesimba shoma, kushandiswa kwema electrode mashoma, ruzha rwakaderera rwekushanda, uye kugadzirwa kwepamusoro.
Kunze kwenyika, muna 1984 muSouth Africa makavakwa 40MVA ine simba re ferrochrome direct current furnace. Ferrosilicon yeChina yemakore 70-80, silicon yeindasitiri, silicomanganese, ferrochrome, solid waste treatment DC mineral heat furnace (single bottom electrode) uye DC steelmaking furnace yakawana ruzivo rwakabudirira, mumakore achangopfuura, China yakavakwa uye yakaiswa mukugadzirwa kweDC furnace ndiyo inonyanya kukosha:
12500-33000kvA Silicon-Manganese DC Mineral Heat Furnace (maerekitirodhi mana)
12500-16500kvA High Silicon DC Mineral Heat Furnace (maerekitirodhi mana)
12500kvA Silicon Barium DC Mineral Heat Furnace (maerekitirodhi mana)
12500kvA Silicon Zirconium DC Mineral Heat Furnace (maerekitirodhi mana)
10000-16000kw Industrial Silicon DC Mineral Heat Furnace (maerekitirodhi mana)
9000kw Ferrochrome DC Mineral Heat Furnace (maerekitirodhi mana)
30000kw Titanium Slag DC Mineral Heat Furnace (1 base electrode)
Kugadzirwa kwezvitofu zvinonyungudutsa zveDC kunomiririra danho guru mukufambira mberi kwetekinoroji. Zvichienzaniswa nechoto cheAC chekare chekupisa, zvakanakira zvacho zviri pachena. Panyaya yekushanda nesimba, choto chinonyungudutsa cheDC chichashandurwa kuita kushanda nesimba kwekupisa zvakanyanya. Nhamba dzechokwadi dzinoratidza kuti mwero wekushandiswa kwesimba rayo wakakwira ne20% kupfuura choto chekare, izvo zvinoderedza kurasikirwa nesimba zvakanyanya uye zvinopa simba rakasimba rekuderedza mari yekugadzira nekuvandudza kushanda zvakanaka kwehupfumi. Panguva imwe chete, choto cheDC chekupisa chemineral chinoratidza kugadzikana kwakanaka uye kudzora panguva yekushanda, uye chinokwanisa kudzora nemazvo mamiriro ekuita muchoto, nokudaro chichivimbisa kuvandudzika kwakasimba mumhando yechigadzirwa uye kuwedzera kwakasimba mukugadzirwa.
Zvichienderana nedata riripo, kuenzanisa kwakazara kwezviratidzo zvekugadzira zveDC furnace neAC furnace, DC furnace output, simba rinoshandiswa nezvimwe zviratidzo zviri nani kupfuura AC furnace, kuwedzera kwezvinobuda kunokonzerwa nekudzikira kwesimba rinoshandiswa kunyungudutsa uye kuvandudzwa kwesimba remagetsi remhedzisiro yekubatana.
Parizvino, kuvandudzwa kwetekinoroji yeDC furnace 4, maelectrode matanhatu nedzimwe nzira dzakawanda dzekugadzira matekinoroji, zvichiratidza zvakanakira zviri pachena zveDC mineral furnace smelting ferroalloys, ndiyo nzira isingadzivisiki yekuchengetedza simba uye mineral furnace yakakura. Pamusoro pezvo, kubatanidzwa kwetekinoroji yakangwara kunoita kuti DC smelting furnace automation degree ive nani zvikuru, mashandiro acho ari nyore uye anoshanda, nekuti kugadzirwa kwebhizinesi kwaunza nyore kukuru.
Panguva imwe chete nepfungwa yekuchengetedzwa kwezvakatipoteredza zvakadzama, chitofu chekunyungudutsa cheDC chinogamuchirawo maitiro egirini enguva iyoyo. Ruzivo rwakakodzera runoratidza kuti chitofu chekunyungudutsa cheDC mukuchengetedza simba nekuderedza kusvibiswa kwakanaka kwazvo, kusvibiswa kwemhepo kwakadzikira zvakanyanya, nekuti budiriro inogara kwenguva refu yakabatsira mukusimudzira simba.
Tichiongorora nhoroondo yekuvandudzwa kwechoto chinonyungudutsa DC, hatigoni kurega kushamisika nebasa rakaoma uye huchenjeri hwevaongorori nemainjiniya. Kubva pakukura kwepfungwa yekutanga, kusvika pakuvandudza nekugadziridza tekinoroji nguva dzose, nhanho yega yega yekudikitira kwavo neuchenjeri. Semuenzaniso, pakugadzira choto chinonyungudutsa DC, kambani yakabudirira kugadzirisa maparamita emagetsi nezvinhu zvechoto uye chimiro mushure mekuyedzwa kwakawanda nekuvandudzwa, kuitira kuti muviri wechoto ugone kumira zviri nani mamiriro akaipisisa akadai sekupisa kwakanyanya uye kumanikidzwa kwakanyanya, uye panguva imwe chete, mashandiro emaelectrodes nezvimwe zvikamu zvakakosha zvakavandudzwawo zvikuru.
Tichitarisa mberi, DC mineral heat furnace inotarisirwa kuwana budiriro huru nekukura:
Chekutanga, hunyanzvi hwetekinoroji huchasimudzira kushanda zvakanaka kwesimba uye kugadzikana kwechoto chinonyungudutsa cheDC kuti chiwedzere kuvandudzika, kubatsira mabhizinesi kuderedza mari yekugadzira uye kuvandudza kukwikwidzana pamusika.
Chechipiri, kugadzirwa kwechoto cheDC mineral heating furnace kuchashandisa njere dzekugadzira, big data nedzimwe nzira dzehungwaru dzekuongorora kuti zvionekwe uye zvidzore otomatiki mamiriro echoto chinonyunguduka, kukurumidzisa kushandiswa kwemidziyo yekubatsira yakangwara, kusanganisira AI intelligent refine, open plug eye robot, connecting electrode robot, automatic pounding machine, inspection robot, high temperature imaging device muchoto, automatic clearing device, continuous casting system, uye zvimwe zvinoshandiswa zve advanced assistant equipment, kuitira kuti pave nebudiriro yekugadzira, kuderedza kushandiswa kwesimba, kuvandudza mhando yechigadzirwa, uye kuona hungwaru negreening yesystem yekugadzira.
Pamusoro pezvo, minda yekushandisa yeDC melting furnace ichawedzerwawo, pamusoro pekuita basa rakakosha muindasitiri yesimbi, inotarisirwa kushandiswa zvakanyanya muindasitiri yemakemikari, zvinhu nezvimwe, zvichibatsira mukufambira mberi nekukura kwemaindasitiri akawanda.
Kubudirira kwekushandiswa kweDC muchoto chekupisa zvicherwa kwakaunza mabhenefiti makuru nemikana yekusimudzira indasitiri yekunyungudutsa. Kuburikidza nekuvandudza zvinhu zvitsva uye kufambira mberi kwetekinoroji, tine chikonzero chekutenda kuti DC icharamba ichiita basa rakakosha mune ramangwana, kukurudzira kufambira mberi kuripo uye kufambira mberi kwetekinoroji yekupisa zvicherwa, tekinoroji yekunyungudutsa kuti ivandudze uye ipe nzvimbo isina muganho yekuvandudza zvigadzirwa zvitsva, kuti maindasitiri aunze tarisiro yakakura uye kufambira mberi kwenguva yemberi.
Muchidimbu, chitofu cheDC mineral heat furnace chine zvakanakira zvacho zvakasiyana uye mikana yakakura yekuvandudzwa, chicharamba chichiita basa rakakosha mumunda weindasitiri mune ramangwana, uye chichapa mipiro yakakura mukufambira mberi kweindasitiri nebudiriro inoenderera mberi. Tiri kutarisira zvimwe zvitsva nekubudirira kusimudzira tekinoroji yeDC mineral heat furnace kusvika padanho idzva!
