Inkqubo yophuhliso lwenkqubo yokunyibilikisa iityhubhu yentsimbi engenamthungo
Umthungo steel umbhobho abavelisi isikali loshishino kunye olunzulu
Isikali kunye nokuqiniswa kwabenzi bemibhobho yentsimbi engenamthungo yamazwe ngamazwe iye yaba ngumkhwa, ngakumbi uxinaniso lwemveliso yepleyiti yombhobho wentsimbi engenamthungo.
Okuphezulu, abavelisi behlabathi be-10 bemibhobho yentsimbi engenamthungo, imveliso yabenzi bemibhobho yentsimbi engenamthungo yehlabathi ibalelwa kwi-80% yemveliso epheleleyo.Arcelor phezulu.
Umthamo wentsimbi yenkampani, umenzi wemibhobho yentsimbi engenamthungo krupthyssen, i-otto kupp kunye ne-arcelinox zonke zidlula iitoni ezizigidi ezi-2.
Ubungakanani obukhulu kunye nokuqiniswa kwenkampani ye-sino-arcelor, efikelele kwi-3.5 yezigidi ukuya kubenzi bemibhobho yensimbi engenamthungo, inciphise kakhulu iindleko zokuthengwa kunye nokunyibilikiswa kwezinto eziluhlaza.
Isiphumo, ukuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso nako kuneenzuzo ezinkulu.
Kukho ngaphezu kwe-16 abavelisi bemibhobho yentsimbi engenamthungo eTshayina, kungabandakanywa inani elikhulu lamashishini abucala, awona makhulu e-tiasteel.
Ngaphambi kokuba umthamo we-1 million t kuphela, i-China yeyona nto isetyenziswayo emhlabeni jikelele kwimibhobho yentsimbi engenamthungo abavelisi.Ngoko ke, kuyimfuneko ukulandela inkqubo yamazwe ngamazwe.
Ngokuhambelana nombono wokuphuhlisa imveliso yepayipi yensimbi engenamthungo ye-nanbao beitai, eye yamiselwa luluntu lwamazwe ngamazwe, imveliso yonyaka ye-taigang kunye ne-baosteel yi-2.5 yezigidi kunye ne-1.5 yezigidi zeetoni ngokulandelanayo.
Isikali ingenamthungo intsimbi abenzi umbhobho amashishini imveliso yentsimbi, ukuphucula uxinaniso abenzi umbhobho yentsimbi e China, ukukhuthaza intsimbi engenamthungo.
Uphuhliso olusempilweni loshishino lwefektri.
Abavelisi bemibhobho yentsimbi engenamthungo yezixhobo zokuvelisa
Izixhobo ezinkulu zemveliso yabenzi bemibhobho yentsimbi engenamthungo yenye indlela yophuhliso lwabavelisi bemibhobho yentsimbi engenamthungo kwihlabathi.Kwinkulungwane yamashumi amabini.
Ngeminyaka yee-1970, abavelisi beetyhubhu zensimbi ezingenamthungo kuphela malunga ne-50t yesithando somlilo, umlinganiselo wemveliso ophakathi kuphela malunga ne-300,000 t / a. Ngonyaka ka-2000, isithando somlilo sombane kunye
Iziko le-AOD likhulu, umthamo wesithando somlilo ufikelele kwi-150t ngaphezulu, isikali semveliso ukuya kwi-1 yezigidi ta.
Okwangoku, amandla eziko lombhobho intsimbi mveliso ingenamthungo e China ayikho enkulu, kuphela iqela baosteel AOD eziko ngaphezu 100t.Ngoko ke, tisco kunye bao
Umvelisi omtsha wemibhobho yensimbi engenamthungo uya kwakha izixhobo zokuvelisa intsimbi enkulu ukuze kuncitshiswe izinga lemveliso ngokubhekiselele kwindlela yamazwe ngamazwe yokuvelisa intsimbi enkulu.
Ben, ukuhlangabezana neemfuno zemarike.
Ukwandiswa kwemibhobho yentsimbi engenamthungo yomenzi wentsimbi Ukuze kuhlangatyezwane nemfuno yemarike, iinkcukacha zabavelisi bentsimbi engenamthungo ziqhubeka zisanda, ingakumbi ububanzi besilebhu buhlala bukhula rhoqo. (4) ityhubhu yentsimbi engenamthungo. imithombo plate.Ukwandiswa 400 series Cr ingenamthungo kumzi-mveliso umbhobho yentsimbi iya kuba umlinganiselo ingenamthungo kumzi-mveliso wentsimbi umbhobho e China.
Enye yeengongoma eziphambili zohlengahlengiso lwesakhiwo seentlobo zasekhaya.Umlinganiselo we-Cr - Ni steel to Cr steel ehlabathini jikelele yi-75:25
Umlinganiselo uphezulu ngakumbi, i-90: 10 e-China, kunye ne-91.3: 8.7 e-tisco ngo-2003. Ngoko ke, ukwandiswa kunye nophuhliso lwabavelisi bemibhobho ye-Cr engenamthungo.
Ukuveliswa kunye nokusetyenziswa ngumsebenzi oyintloko wabavelisi bemibhobho yensimbi engenamthungo e-China.Tisco iceba ukuvelisa umlinganiselo we-Cr - Ni steel ukuya kwi-Cr steel kwi-2004.
Kwixesha elizayo, umlinganiselo wemveliso yentsimbi ye-Cr uya kwandiswa ngakumbi ngokunyuka kwemfuno. Ukusetyenziswa ngokufanelekileyo kwe-nickel encinci okanye akukho.
Abavelisi abatsha beetyhubhu zensimbi ezingenamthungo kunye nesigaba esiphindwe kabini abavelisi beetyhubhu ezingenamthungo abanako ukunciphisa kuphela iindleko zabenzi beetyhubhu zetsimbi ezingenamthungo, kodwa banokubaluleka kobuchule.
Ukuba nobuchule kubuchwephesha bemveliso yokunyibilikisa kwezi ntlobo zentsimbi ukuhlangabezana neemfuno zentengiso ikwayindlela yophuhliso lwemveliso yentsimbi yabavelisi bemibhobho yentsimbi engenamthungo eTshayina.
