IiNdlela eziPhambili kwiMarike
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, kwaye ukuya kuma-2,800mm ubude.
- Ukunyuka kwexabiso 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 kwendalo, kunye nokukhula kwemveliso ye-EAF, kwihlabathi jikelele. Oku kuqikelelwa ukuba konyusa ixabiso lemveliso ye-EAF nge-1-5%, ngokuxhomekeke kwiinkqubo zokuthengwa kwelitye lokusila, kwaye oku kunokwenzeka ukuba kuthintele ukuveliswa kwentsimbi, 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 kwe-particle. 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 iMarike
- 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 lokwakha indawo yokuhlala, kulindeleke ukuba ixhase imfuno yasekhaya yee-alloys ezingenayo i-ferrous kunye nentsimbi kunye nentsimbi, eyona nto ilungileyo ekukhuleni 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 kwe-50 amawaka eetoni ze-metric yee-electrode ze-UHP zegraphite kulindeleke ukuba zingqinwe ngamanqanaba amva exesha loqikelelo.
-Zonke ezi zinto zikhankanywe ngasentla, nazo, kulindeleke ukuba zonyuse imfuno yegraphite electrode kulo mmandla ngexesha lokuqikelela.
