Kuhlelelwe ukunciphisa i-coefficient yokuguqula umthamo ukuze kube lula ukushintshwa kweziko likagesi ngama-converters. Kulolu hlelo, ama-coefficients okuguqulwa kwamandla okuguqulwa kwamandla kagesi kanye nezithando zikagesi zishintshiwe futhi zancishiswa, kodwa ukuncishiswa kwezithando zikagesi kukhulu, okusho ukuthi abaguquli bomthamo ofanayo bangashintshwa ngezithando zikagesi zamandla amakhulu. Ngokwezibalo zethu, isiguquli esinamandla amathani angama-70 singashintshwa kuphela ngesithando somlilo esinamandla amathani angama-75 (ishintshwe ngo-1.25: 1) noma amathani ayi-105 (ashintshwe ngo-1: 1) ngokuya ngokuguqulwa kwamandla okuqala. isici; Ngemuva kokuqaliswa kohlelo, ingashintshwa yisithando somlilo esinamandla amathani angu-120 ngesilinganiso se-1: 1.
Insimbi ye-EAF ingase iwamukele amathuba okuthuthukiswa, okuzozuzisa iketango lemboni ye-scrap steel kanye ne-graphite electrode. Isizathu sokuthi kungani inqubomgomo ithanda insimbi yesithando somlilo sikagesi ukuthi inqubo yokwenza insimbi yokugeleza okufushane yesithando somlilo inezinzuzo ezisobala zemvelo. Ingxenye yokukhishwa kwensimbi yesithando somlilo waseChina iphansi kakhulu kuneyamazwe angaphandle. Silinganisela ukuthi insimbi yesithando somlilo ingawamukela amathuba abalulekile entuthuko. Esikhathini esifushane, kuhle embonini yokucubungula izinsalela; intengo yama-electrode e-graphite iye yaphindeka kakhulu futhi kulindeleke ukuthi iphinde isekelwe.
Uhlelo lwakamuva lokushintsha umthamo wensimbi luqine kakhulu, futhi iziko likagesi lingashintshwa ngamanani alinganayo. UMnyango Wezimboni Nobuchwepheshe Bolwazi ukhiphe “Izinyathelo Zokuqalisa Zokushintshwa Kwamandla Omsebenzi Wensimbi” wakamuva, onezilawuli eziqinile ekushintsheni komthamo wensimbi: (1) Chaza ngokucacile ububanzi bemishini yokushintsha umthamo. (2) Kuyadingeka “ukunciphisa” isabelo esingena esikhundleni. (3) Ngokokulawulwa kwenani eliphelele lokukhiqiza esifundeni, okokusebenza kokuphuma okusetshenziselwa ukushintshwa kufanele kususwe endaweni. Lolu hlelo lubeka ngokucacile ukuthi izinkampani zensimbi zizoshintsha iziguquli zibe nezithando zikagesi, futhi ukushintshwa okufanayo kungenziwa.
Alukho uphawu lokunethezeka kunqubomgomo, elungele izinto eziyisisekelo, futhi inethemba ngezisekelo ngaphambi koMkhosi Wasentwasahlobo. Uma sibheka lolu hlelo, inqubomgomo yokulawula amandla okukhiqiza insimbi iyaqhubeka nokuhambisana nokucindezela okukhulu, futhi akukho sibonakaliso sokuphumula. IKhongolose Kazwelonke ye-19 yeQembu LamaKhomanisi laseChina nayo ithe izoqhubeka nokukhuthaza izinguquko eziphathelene nokuhlinzekwa kwempahla. Esikhathini esifushane, ukuvikelwa kwemvelo kanye nemikhawulo yokukhiqiza ngesikhathi sokushisa kuzosekela umkhakha wensimbi. Silinganisela ukuthi kuze kuphele inkathi yokushisisa ngoMashi 15, okuyisisekelo kokuhlinzekwa kwemboni yensimbi nensimbi kulindeleke ukuthi kuhlale kuqinile, kuyilapho ukuchuma ngemva kwenkathi yokushisisa kuzoba khona. Ukungaqiniseki. Kulinganiselwa ukuthi izinzuzo zezinkampani zensimbi ezisohlwini ngo-2017Q4 no-2018Q1 zisenethemba elilinganiselwe, futhi ukulinganiswa komkhakha wensimbi kuphansi, futhi kungase kube nokuphindaphinda ngaphambi koMkhosi Wasentwasahlobo.
