IiNdlela zeMarike eziphambili
Ukwandiswa kweMveliso yeNsimbi ngeTekhnoloji ye-Electric Arc Furnace
- Isithando sombane se-arc sithatha i-steel scrap, i-DRI, i-HBI (intsimbi eshushu yebriquetted, edityanisiweyo ye-DRI), okanye intsimbi yehagu ngendlela eqinileyo, kwaye iyayinyibilika ukuvelisa intsimbi.Kwindlela ye-EAF, umbane unika amandla okunyibilikisa i-feedstock.
- I-electrode yegraphite isetyenziswa ikakhulu kwi-electric arc furnace (EAF) inkqubo yokwenza intsimbi, ukunyibilikisa intsimbi yentsimbi.Ii-electrodes zenziwe ngegraphite ngenxa yokukwazi ukumelana nobushushu obuphezulu.Kwi-EAF, incam ye-electrode inokufikelela kwi-3,000º Fahrenheit, esisiqingatha sobushushu bomphezulu welanga.Ubungakanani bee-electrode buyahluka ngokubanzi, ukusuka kwi-75mm ububanzi, ukuya kubukhulu obungange-750mm ububanzi, ukuya kuma-2,800mm ubude.
- Ukunyuka kwamaxabiso kweeelectrode zegraphite kunyuse iindleko zeEAF.Umlinganiselo we-EAF uqikelelwa ukuba uza kusebenzisa malunga ne-1.7 kg ye-electrode yegraphite ukuvelisa itoni enye yentsimbi.
- Ukunyuka kwamaxabiso kubalelwa ekudityanisweni kweshishini, kwihlabathi jikelele, ukuvalwa kwamandla eTshayina, kulandela ukulawulwa kokusingqongileyo, kunye nokukhula kwemveliso ye-EAF, kwihlabathi jikelele.Oku kuqikelelwa ukwandisa ixabiso lemveliso ye-EAF nge-1-5%, ngokuxhomekeke kwiinkqubo zokuthengwa kwe-mill, kwaye oku kunokwenzeka ukuba kuthintele imveliso yentsimbi, njengoko kungekho nto ithatha indawo ye-graphite electrode kwimisebenzi ye-EAF.
- Ukongezelela, imigaqo-nkqubo yaseChina yokujongana nongcoliseko lomoya iye yaqiniswa yi-curbs yokubonelela ngamandla, kungekhona kuphela icandelo lensimbi, kodwa kunye namalahle, i-zinc, kunye namanye amacandelo avelisa ukungcola.Ngenxa yoko, imveliso yentsimbi yaseTshayina iyancipha kakhulu kwiminyaka edlulileyo.Nangona kunjalo, oku kulindeleke ukuba kube nefuthe elihle kumaxabiso ensimbi kunye neentsimbi zensimbi kummandla, ukuze ujabulele imida engcono.
-Zonke ezi zinto zikhankanywe ngasentla, kulindeleke ukuba ziqhube imakethi yegraphite electrode ngexesha loqikelelo.
Ingingqi yaseAsia-Pacific ukuba ilawule kwiMarike
- Ummandla we-Asia-Pacific ulawula isabelo semarike yehlabathi.I-China ibambe esona sabelo sikhulu ngokusetyenziswa kunye nomthamo wemveliso yee-electrode zegraphite kwimeko yehlabathi.
- Izigunyaziso zomgaqo-nkqubo omtsha eBeijing nakwamanye amaphondo amakhulu kweli lizwe zinyanzela abavelisi bentsimbi ukuba bavale umthamo we-1.25 yezigidi zeetoni zentsimbi eziveliswe ngendlela enobungozi bokusingqongileyo ukwenzela ukuvelisa umthamo omtsha we-1 yezigidi zeetoni zentsimbi.Imigaqo-nkqubo enjalo ixhase ukutshintshwa kwabavelisi ukusuka kwiindlela eziqhelekileyo zokuvelisa intsimbi ukuya kwindlela ye-EAF.
- Imveliso ekhulayo yeemoto, kunye nokwanda kweshishini lolwakhiwo lwezindlu zokuhlala, kulindeleke ukuba lixhase imfuno yasekhaya yee-alloys ezingenayo i-ferrous kunye nentsimbi kunye nentsimbi, eyona nto ilungileyo yokukhula kwemfuno ye-graphite electrode kwiminyaka ezayo. .
- Umthamo wangoku wemveliso ye-UHP graphite electrode e-China ijikeleze i-50 yeetoni zeemetric ngonyaka.Imfuno yee-electrode ze-UHP e-China kulindeleke ukuba ibone ukukhula okubonakalayo kwixesha elide kwaye umthamo owongezelelweyo ongaphezulu kwamawaka angama-50 eetoni zee-metric ze-UHP ze-electrode zegraphite kulindeleke ukuba zingqinwe ngamanqanaba amva kwexesha loqikelelo.
-Zonke ezi zinto zikhankanywe ngasentla, nazo, kulindeleke ukuba zonyuse imfuno yegraphite electrode kulo mmandla ngexesha lokuqikelela.
