Ndi kusintha kosalekeza m'mafakitale a mafunde, DC melting floorn yokhala ndi ubwino wake wapadera komanso mwayi waukulu wopita patsogolo, pang'onopang'ono ikuyamba kuoneka ngati nyenyezi yowala yotsogolera kupita patsogolo kwaukadaulo kwa makampaniwa.
Pakadali pano, ukadaulo watsopano wagwiritsidwa ntchito mu migodi ya DC kuyambira m'ma 1970. Kukhazikika kwa arc ya ng'anjo ya DC, kuchuluka kwa mphamvu, kutentha kwambiri, kugwiritsa ntchito mphamvu zochepa, kugwiritsa ntchito ma elekitirodi ochepa, phokoso lochepa, komanso kupanga bwino.
Kunja, mu 1984 ku South Africa, ng'anjo ya ferrochrome yamphamvu ya 40MVA yokhala ndi mpweya wochuluka wa carbon. Nkhokwe ya ferrosilicon ya China ya zaka 70-80, silicon ya mafakitale, silicomanganese, ferrochrome, chithandizo cha zinyalala zolimba, ng'anjo yotentha ya DC mineral heat (electrode imodzi pansi) ndi ng'anjo ya DC steelmaking yapeza chidziwitso chabwino, m'zaka zaposachedwapa, China yamangidwa ndikuyikidwa mu kupanga ng'anjo ya DC makamaka:
12500-33000kvA Silicon-Manganese DC Mineral Heat Furnace (maelekitirodi 4)
12500-16500kvA High Silicon DC Mineral Heat Furnace (ma electrode 4)
12500kvA Silicon Barium DC Mineral Heat Furnace (ma electrode 4)
12500kvA Silicon Zirconium DC Mineral Heat Furnace (ma electrode 4)
10000-16000kw Industrial Silicon DC Mineral Heat Furnace (ma electrode 4)
Furnace Yotenthetsera Mineral ya 9000kw Ferrochrome DC (ma electrode 4)
30000kw Titanium Slag DC Mineral Heat Furnace (electrode imodzi yoyambira)
Kukula kwa uvuni wosungunula wa DC kukuyimira kupita patsogolo kwakukulu pakupita patsogolo kwaukadaulo. Poyerekeza ndi uvuni wotenthetsera wa AC wachikhalidwe, ubwino wake ndi wodziwikiratu. Ponena za kugwiritsa ntchito bwino mphamvu, uvuni wosungunula wa DC udzasinthidwa kukhala mphamvu yotenthetsera bwino kwambiri. Ziwerengero zenizeni zikuwonetsa kuti kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito ndi pafupifupi 20% kuposa uvuni wosungunula wamba, zomwe zimachepetsa kwambiri kutayika kwa mphamvu ndikuyika chilimbikitso champhamvu chochepetsera ndalama zopangira ndikukweza magwiridwe antchito azachuma. Nthawi yomweyo, uvuni wotenthetsera wa DC wamchere umasonyeza kukhazikika bwino komanso kulamulira bwino panthawi yogwira ntchito, ndipo umatha kuwongolera molondola momwe zinthu zimachitikira mu uvuni, motero kuonetsetsa kuti zinthu zikuyenda bwino komanso kuti kupanga kukukula mosalekeza.
Malinga ndi zomwe zilipo, kufananiza kwathunthu kwa zizindikiro zopangira ng'anjo ya DC ndi ng'anjo ya AC, kutulutsa kwa ng'anjo ya DC, kugwiritsa ntchito mphamvu ndi zizindikiro zina kuli bwino kwambiri kuposa ng'anjo ya AC, kuwonjezeka kwa kutulutsa kumachitika chifukwa cha kuchepa kwa kugwiritsa ntchito mphamvu yosungunulira komanso kusintha kwa mphamvu ya zotsatira zake.
Pakadali pano, chitukuko cha ukadaulo wa DC furnace 4, ma electrode 6 ndi zina zambiri, zomwe zikuwonetsa bwino ubwino wa DC mineral furnace smelting ferroalloys, ndi njira yosapeŵeka yosungira mphamvu ndi mineral furnace yayikulu. Kuphatikiza apo, kuphatikiza ukadaulo wanzeru kumapangitsa digiri ya DC smelting furnace automation kukhala yabwino kwambiri, ntchito yake ndi yosavuta komanso yothandiza, chifukwa kupanga kwa bizinesi kwabweretsa mwayi waukulu.
Pa nthawi yomweyi, mfundo yokhudza kuteteza chilengedwe, ng'anjo yosungunuka ya DC ikugwiritsanso ntchito njira yobiriwira ya nthawi imeneyo. Deta yofunikira ikuwonetsa kuti ng'anjo yosungunuka ya DC ikugwira ntchito bwino kwambiri populumutsa mphamvu ndi kuchepetsa mpweya woipa, mpweya woipa wachepa kwambiri, chifukwa chitukuko chokhazikika chathandiza kuti pakhale mphamvu.
Poyang'ana mbiri ya chitukuko cha ng'anjo yosungunuka ya DC, sitingalephere kudabwa ndi ntchito yolimba komanso nzeru zolimbitsa za ofufuza ndi mainjiniya. Kuyambira pa germ ya lingaliro loyambirira, mpaka kusintha kosalekeza ndi kukonza ukadaulo, gawo lililonse la thukuta lawo ndi nzeru zawo. Mwachitsanzo, popanga ng'anjo yosungunuka ya DC, bizinesi yakhala ikukonzekera bwino magawo amagetsi ndi zida za ng'anjo ndi kapangidwe kake pambuyo poyesa ndi kusintha kambiri, kuti thupi la ng'anjo lizitha kupirira bwino mikhalidwe yovuta kwambiri monga kutentha kwambiri ndi kuthamanga kwambiri, ndipo nthawi yomweyo, magwiridwe antchito a ma electrode ndi zigawo zina zofunika nawonso asintha kwambiri.
Poganizira zamtsogolo, ng'anjo yotentha ya mchere ya DC ikuyembekezeka kukwaniritsa chitukuko chachikulu:
Choyamba, luso lamakono lidzalimbikitsa kugwiritsa ntchito bwino mphamvu ndi kukhazikika kwa uvuni wosungunuka wa DC kuti upitirire patsogolo, kuthandiza mabizinesi kuchepetsa ndalama zopangira ndikukweza mpikisano pamsika.
Kachiwiri, kupanga ng'anjo yotentha ya DC kudzagwiritsa ntchito luntha lochita kupanga, deta yayikulu ndi ukadaulo wina wanzeru kuti zikwaniritse kuyang'anira nthawi yeniyeni komanso kuwongolera zokha momwe ng'anjo imasungunuka, kufulumizitsa kugwiritsa ntchito zida zothandizira zanzeru, kuphatikiza kukonza kwanzeru kwa AI, loboti yotseguka maso, loboti yolumikizira ma electrode, makina oponda okha, loboti yowunikira, chipangizo chojambula kutentha kwambiri mu ng'anjo, chipangizo choyeretsera chokha, makina operekera zinthu mosalekeza, ndi zida zina zothandizira zapamwamba, kuti ziwongolere bwino ntchito yopanga, kuchepetsa kugwiritsa ntchito mphamvu, kukonza mtundu wa malonda, ndikuzindikira luntha ndi kubiriwira kwa makina opangira.
Kuphatikiza apo, minda yogwiritsira ntchito uvuni wosungunuka wa DC idzakulitsidwanso, kuwonjezera pakuchita gawo lofunika kwambiri mumakampani opanga zitsulo, ikuyembekezeka kugwiritsidwa ntchito kwambiri mumakampani opanga mankhwala, zipangizo ndi minda ina, zomwe zikuthandizira kupita patsogolo ndi chitukuko cha mafakitale ambiri.
Kugwiritsa ntchito bwino kwa DC mu uvuni wotenthetsera mchere kwabweretsa zabwino zambiri komanso mwayi wopititsa patsogolo makampani opanga zitsulo. Kudzera mu luso lopitilira komanso kupita patsogolo kwaukadaulo, tili ndi chifukwa chokhulupirira kuti DC ipitiliza kuchita gawo lofunika mtsogolo, kulimbikitsa chitukuko chopitilira ndi kupita patsogolo kwa ukadaulo wa zitsulo zotenthetsera mchere, ukadaulo wosungunulira kuti ukhale wabwino komanso kupereka malo opanda malire opangira zinthu zatsopano, kuti gawo la mafakitale libweretse chiyembekezo chachikulu komanso chitukuko chokhazikika chamtsogolo.
Mwachidule, ng'anjo yotentha ya mchere ya DC yokhala ndi ubwino wake wapadera komanso mwayi waukulu wopita patsogolo, ipitiliza kugwira ntchito yofunika kwambiri m'mafakitale amtsogolo, ndikupereka zopereka zazikulu pakupititsa patsogolo mafakitale ndi chitukuko chokhazikika. Tikuyembekezera zatsopano zambiri komanso zopambana kuti tikweze ukadaulo wa ng'anjo yotentha ya mchere ya DC kufika pachimake chatsopano!
