Kwiminyaka yakutshanje, ishishini lombhobho wentsimbi elingenamthungo welizwe lethu liye lafumana uphuhliso olukhawulezayo kwimbali, kunye nemveliso kunye nokuthengisa iminyaka emi-6 eqhubekayo, iziphumo zohlengahlengiso lwesakhiwo semveliso ziyamangalisa, kwaye izinga lokuzixhasa lombhobho wentsimbi liyanda. unyaka nonyaka.Ngo-2004, ukuveliswa kombhobho wensimbi kwafikelela kwi-21.23 yezigidi zeetoni, kubalwa ngaphezu kwe-25% yemveliso yepayipi yensimbi yehlabathi.Utshintsho lwezobuchwepheshe kunye notyalo-mali lufikelele kwirekhodi eliphezulu, kwaye izixhobo zobuchwepheshe ziphuculwe kakhulu.Izigidi ezibini zeetoni zamashishini okwenziwa kwemibhobho yentsimbi engenamthungo ziye zavela, zingena kuluhlu lwamaqela amakhulu ehlabathi.
Njengoko kuphuhliso loshishino lwentsimbi China, nangona ishishini umbhobho yentsimbi wenze impumelelo ephawulekayo kwiminyaka yakutshanje, accounting ngaphezu 1/4 yemveliso yehlabathi, kusekho umsantsa ethile kunye nenqanaba eliphezulu ngamazwe ngokwemiqathango yezixhobo zobugcisa. , umgangatho wemveliso kunye nebakala, isikali soqoqosho lweshishini kunye nezalathi eziphambili zobugcisa kunye nezoqoqosho.
Ngokuhlalutya indlela yophuhliso kunye nepateni yamashishini anxulumeneyo kushishino lwemibhobho yentsimbi engenamthungo, kunye nempumelelo kunye neengxaki zeshishini lombhobho wentsimbi yaseTshayina, saqonda ukuba imarike yasekhaya inenzuzo ethile kunye nesithuba sophuhliso, kunye nesithuba semarike yamazwe ngamazwe. iya isiba nkulu kwaye inkulu, kwaye eyona ndlela iphambili yokuphucula isabelo semarike kukukhuphisana.Ukuze siqhubele phambili ukukhulisa ukhuphiswano, kufuneka silixhakamfule eli thuba lihle langoku lokunciphisa umsantsa phakathi kweentlobo ngeentlobo, umgangatho kunye neendleko zeemveliso kunye nenqanaba eliphezulu lamazwe ngamazwe ngokukhawuleza kangangoko, ukuze sifikelele kwinqanaba eliphezulu lamazwe ngamazwe lezixhobo zemveliso kunye nobuchwepheshe. , kwaye wenze ilizwe lethu libe namandla anamandla kwimveliso yeetyhubhu zetsimbi kwihlabathi.
1. Uphuhliso lwemveliso kunye nesimo esibonakalayo sokusetyenziswa kweshishini lombhobho wensimbi engenamthungo eChina
Ngo-2004, imveliso yombhobho wentsimbi engenamthungo yaseTshayina kunye nombhobho wentsimbi odityanisiweyo yeyokuqala emhlabeni, kwaye umbhobho wentsimbi ongenamthungo uye waba luhlobo lokuthumela ngaphandle kwe-net ngo-2003. .Ukukhula kwemveliso yentsimbi yombhobho iphantse ihambelane nokukhula kweemveliso zentsimbi ezigqityiweyo kweli lizwe, oko kukuthi, ukukhula okuqhelekileyo ngonyaka kweemveliso zentsimbi ezigqityiweyo yi-21.64%, kunye nokukhula kombhobho wentsimbi yi-20.8%, kunye nombhobho / umlinganiselo wezinto eziphathekayo. igcinwe malunga ne-7%.
Ukususela kwi-1981 ukuya kwi-2004, indlela yonke yemveliso kunye nokusetyenziswa okubonakalayo kwetyhubhu yensimbi engenamthungo iye yanda ngokuthe ngcembe kwaye ngokuhambelanayo.Ngaphambi kuka-1999, ukusetyenziswa bekuphezulu kunemveliso ngokuguquguquka okuthile (malunga ne-800,000 t).Phambi kuka-2002, ukusetyenziswa okubonakalayo bekukukhulu kancinci kunemveliso yasekhaya, kwaye ngo-2003, bekuthe tyaba.Ngo-2004, imveliso yayinkulu kancinci kunokusetyenziswa okubonakalayo, kwaye kulindeleke ukuba imveliso iya kuqalisa ukudlula kakhulu ukusetyenziswa okubonakalayo kwi-2005.
2. Ubume bokwakhiwa komthamo weshishini lombhobho wentsimbi waseTshayina ongenamthungo
Kwiintsuku ezimbalwa ezidlulileyo, ilizwe lethu linabavelisi bemibhobho engenamthungo 130 okanye kunjalo, phantse iiseti ezingama-200 zeyunithi.Phakathi kwazo, kukho iinkampani eziphantse zibe ngama-30 ezinokuvelisa imibhobho egqityiweyo eshushu egqityiweyo enezixhobo zobuchwepheshe obupheleleyo, kunye nomthamo opheleleyo wemveliso ongaphezu kwezigidi ezi-6 t, ebalwa ngaphezu kwe-60% yexabiso lilonke lemibhobho yentsimbi engenamthungo.Olu hlobo lwesityalo sokuvelisa uninzi lwamashishini karhulumente, iteknoloji ephezulu kunye nezixhobo, umthamo ophezulu wemveliso yomgca omnye (iyunithi ye-Tianguan 250, iyunithi ye-Baoshan Steel 140 ngaphezu kwe-800 yeetoni eziliwaka), umgangatho wemveliso ulungile, intsimbi engenamthungo. imveliso yombhobho lishishini elikhokelayo.Amanye amashishini ubukhulu becala ngamashishini amancinci naphakathi abonelela ityhubhu okanye inkunkuma ye-tube billet yokuqengqeleka okubandayo.Izixhobo zamashishini anjalo zilula.Inkqubo jikelele kukusebenzisa ukugqobhoza + intloko okanye ukugqobhoza + umbhobho oqengqelekayo + intloko emva kokuxhobisa ngokubanda okuqengqelekayo.
