Kuhlelwe ukunciphisa i-coefficient yokuguqulwa kwamandla kagesi ukuze kube lula ukufaka esikhundleni izitofu zikagesi ngabaguquli. Kulolu hlelo, ama-coefficient okuguqulwa kwamandla kagesi abaguquli kanye nezitofu zikagesi alungisiwe futhi ancishisiwe, kodwa ukwehla kwezitofu zikagesi kukhulu, okusho ukuthi abaguquli abanamandla afanayo bangashintshwa ngezitofu zikagesi ezinomthamo omkhulu. Ngokwezibalo zethu, i-converter enamandla angamathani angu-70 ingashintshwa kuphela ngesitofu sikagesi esinomthamo wamathani angu-75 (esishintshwa ku-1.25:1) noma amathani angu-105 (esishintshwa ku-1:1) ngokwesici sokuqala sokuguqulwa kwamandla; Ngemva kokusetshenziswa kohlelo, lungashintshwa isitofu sikagesi esinomthamo wamathani angu-120 ngesilinganiso esingu-1:1.
Insimbi ye-EAF ingamukela amathuba okuthuthukiswa, okuzozuzisa uchungechunge lwezimboni zensimbi eqoshiwe kanye ne-graphite electrode. Isizathu sokuthi le nqubomgomo ithanda insimbi yesithando sikagesi ukuthi inqubo yokwenza insimbi emfushane yesithando sikagesi inezinzuzo ezisobala zemvelo. Ingxenye yomkhiqizo wensimbi yesithando sikagesi saseShayina iphansi kakhulu kuneyamazwe angaphandle. Silinganisela ukuthi insimbi yesithando sikagesi ingamukela amathuba abalulekile okuthuthukiswa. Esikhathini esifushane, ilungele imboni yokucubungula izinsimbi; intengo yama-electrode e-graphite ikhuphuke kakhulu futhi kulindeleke ukuthi isekelwe ngokwengeziwe.
Uhlelo lwakamuva lokushintsha umthamo wensimbi luqinile kakhulu, futhi izitofu zikagesi zingashintshwa ngamanani alinganayo. UMnyango Wezimboni Nobuchwepheshe Bolwazi ukhiphe "Izinyathelo Zokusebenzisa Zokushintsha Umthamo Wensimbi Osebenzayo", onezilawuli eziqinile zokushintsha umthamo wensimbi: (1) Chaza ngokuqinile ububanzi bemishini yokushintsha umthamo. (2) Kuyadingeka "ukunciphisa" isabelo sokushintsha. (3) Ngokusho kokulawulwa komthamo wokukhiqiza ophelele esifundeni, imishini yokuphuma esetshenziselwa ukushintsha kumele isuswe endaweni yayo. Uhlelo lusho ngokusobala ukuthi izinkampani zensimbi zizoshintsha iziguquli ngezitofu zikagesi, futhi ukushintshwa okufanayo kungasetshenziswa.
Akukho sibonakaliso sokuphumula kule nqubomgomo, okuyinto enhle ngezisekelo, futhi inethemba ngezisekelo ngaphambi koMkhosi waseNtwasahlobo. Uma sibheka lolu hlelo, inqubomgomo yokulawula amandla okukhiqiza insimbi iyaqhubeka nokunamathela ekucindezelweni okuphezulu, futhi akukho sibonakaliso sokuphumula. I-19th National Congress yeQembu lamaKhomanisi laseShayina nayo ithe izoqhubeka nokukhuthaza izinguquko ohlangothini lokuhlinzeka. Esikhathini esifushane, ukuvikelwa kwemvelo kanye nemikhawulo yokukhiqiza ngesikhathi sokushisa kuzosekela umkhakha wensimbi. Silinganisela ukuthi kuze kube yilapho isizini yokushisa iphela ngoMashi 15, izisekelo zokuhlinzekwa kwemboni yensimbi nensimbi kulindeleke ukuthi zihlale ziqinile, kuyilapho ukuchuma ngemva kwesizini yokushisa kuzohlala kukhona. Ukungaqiniseki. Kulinganiselwa ukuthi imali engenayo yezinkampani zensimbi ezisohlwini ngo-2017Q4 no-2018Q1 isenethemba elikhulu, futhi inani lomkhakha wensimbi liphansi, futhi kungase kube nokubuyela emuva ngaphambi koMkhosi waseNtwasahlobo.
