Imarike yegraphite electrode kulindeleke ukuba ibhalise i-CAGR engaphezulu kwe-9% ngexesha loqikelelo.Izinto eziphambili ezisetyenziselwa ukuveliswa kwe-electrode yegraphite yinaliti ye-coke (mhlawumbi i-petroleum-based okanye i-coal-based).
Ukunyuka kwemveliso yentsimbi kunye nentsimbi kumazwe asakhasayo, ukunyuka kokufumaneka kwezinto ezilahliweyo zentsimbi e-China ngaloo ndlela konyusa ukusetyenziswa kweziko lombane le-arc kulindeleke ukuba kuqhube imfuno yentengiso ngexesha lentelekelelo.
Ukunyuka kwamaxabiso e-coke yenaliti okukhokelela ekuxineni kobonelelo phakathi kwezinye izithintelo ezinjengokukhula okulinganiselweyo kwe-UHP graphite electrode eTshayina kunye nokudityaniswa koshishino lwegraphite electrode kunokuthintela ukukhula kwemarike.
Ukunyuka kwemveliso yentsimbi ngetekhnoloji yombane ye-arc e-China kulindeleke ukuba isebenze njengethuba lentengiso kwixa elizayo.
IiNdlela zeMarike eziphambili
Ukwandiswa kweMveliso yeNsimbi ngeTekhnoloji ye-Electric Arc Furnace
- Isithando somlilo se-arc sombane sithatha i-steel scrap, i-DRI, i-HBI (intsimbi eshushu yebriquetted, edityanisiweyo ye-DRI), okanye i-iron yehagu ngendlela eqinileyo, kwaye iyayinyibilikisa 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 inkunkuma yentsimbi.Ii-electrodes zenziwe ngegraphite ngenxa yokukwazi ukumelana nobushushu obuphezulu.Kwi-EAF, incam ye-electrode inokufikelela kwi-3,000 Fahrenheit, esisiqingatha sobushushu bomhlaba welanga.Ubungakanani bee-electrode buyahluka ngokubanzi, ukusuka kwi-75mm ububanzi, ukuya kubukhulu obungange-750mm ububanzi, ukuya kuma-2,800mm ubude.
- Ukunyuka kwamaxabiso eeelectrode 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 liphela, ukuvalwa kwamandla eTshayina, kulandela ukulawulwa kokusingqongileyo, kunye nokukhula kwemveliso ye-EAF, kwihlabathi liphela.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 yimiqobo yokubonelela ngamandla, kungekhona kuphela icandelo lentsimbi, kodwa kunye namalahle, i-zinc, kunye namanye amacandelo avelisa ungcoliseko oluthile.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 lwendawo yokuhlala, kulindeleke ukuba lixhase imfuno yasekhaya yee-alloys ezingenayo i-ferrous kunye nentsimbi kunye nentsimbi, nto leyo iyinto elungileyo yokukhula kwemfuno ye-electrode yegraphite kwiminyaka ezayo.
- Umthamo wangoku wemveliso yee-electrode zegraphite ze-UHP e-China zimalunga nama-50 amawaka eetoni 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.
