Imarike ye-graphite electrode kulindeleke ukuba ibhalise i-CAGR engaphezulu kwe-9% ngexesha lexesha eliqikelelweyo. Izinto ezisetyenziswa kakhulu ekuveliseni i-graphite electrode yi-needle coke (nokuba isekelwe kwi-petroleum okanye isekelwe kumalahle).
Ukunyuka kwemveliso yesinyithi nentsimbi kumazwe asakhasayo, ukwanda kokufumaneka kweziqwenga zesinyithi eTshayina ngaloo ndlela kwandiswe ukusetyenziswa kwezitofu zombane kulindeleke ukuba kunyuse imfuno yemarike ngexesha lexesha eliqikelelweyo.
Ukunyuka kwamaxabiso e-needle coke okubangela ukuqina kobonelelo phakathi kwezinye izinto ezithintela ukukhula okuncinci kwe-UHP graphite electrode eTshayina kunye nokudityaniswa kweshishini le-graphite electrode kusenokwenzeka ukuba kuthintele ukukhula kwemarike.
Ukwanda kwemveliso yentsimbi ngokusebenzisa ubuchwepheshe bombane be-arc oven eTshayina kulindeleke ukuba kusebenze njengethuba kwimarike kwixesha elizayo.
Iindlela eziphambili zeMarike
Ukwanda kweMveliso yeNsimbi ngeTekhnoloji yeSithando soMbane se-Electric Arc
- Isithando somlilo se-arc sombane sithatha i-steel scrap, i-DRI, i-HBI (i-hot briquetted iron, eyi-compact DRI), okanye i-pig iron kwimo eqinileyo, size siyinyibilikise ukuze ivelise intsimbi. Kwindlela ye-EAF, umbane unika amandla okunyibilikisa i-feedstock.
- I-electrode yegrafiti isetyenziswa kakhulu kwinkqubo yokwenza intsimbi ye-electric arc furnace (EAF), ukunyibilikisa inkunkuma yentsimbi. Ii-electrode zenziwe ngegrafiti ngenxa yokukwazi kwayo ukumelana namaqondo obushushu aphezulu. Kwi-EAF, incam ye-electrode ingafikelela kwi-3,000 Fahrenheit, nto leyo eyisiqingatha sobushushu bomphezulu welanga. Ubungakanani bee-electrode buyahluka kakhulu, ukusuka kwi-75mm ububanzi, ukuya kwi-750mm ububanzi, kunye nobude obufikelela kwi-2,800mm.
- Ukunyuka kwamaxabiso ee-electrode zegrafiti kunyuse iindleko zee-EAF mills. I-EAF eqhelekileyo iqikelelwa ukuba isebenzisa malunga ne-1.7 kg yee-electrode zegrafiti ukuvelisa itoni enye yentsimbi.
- Ukunyuka kwamaxabiso kubangelwe kukuhlanganiswa kwemizi-mveliso, kwihlabathi liphela, ukuvalwa kwamandla eTshayina, emva kokulawulwa kwendalo, kunye nokukhula kwemveliso ye-EAF, kwihlabathi liphela. Oku kuqikelelwa ukuba kuya kunyusa iindleko zemveliso ye-EAF nge-1-5%, kuxhomekeke kwiindlela zokuthenga zefektri, kwaye oku kunokwenzeka ukuba kuthintele imveliso yentsimbi, njengoko kungekho nto inokuthatha indawo ye-graphite electrode kwimisebenzi ye-EAF.
- Ukongeza, imigaqo-nkqubo yaseTshayina yokujongana nongcoliseko lomoya iqiniswe yimida eqinileyo yokubonelela, kungekuphela nje kwicandelo lesinyithi, kodwa nakwicandelo lamalahle, i-zinc, kunye namanye amacandelo avelisa ungcoliseko lwamasuntswana. Ngenxa yoko, imveliso yesinyithi yaseTshayina yehle kakhulu kwiminyaka edlulileyo. Nangona kunjalo, oku kulindeleke ukuba kube nefuthe elihle kumaxabiso esinyithi kunye neefektri zesinyithi kulo mmandla, ukuze zifumane inzuzo engcono.
- Zonke ezi zinto zikhankanyiweyo apha ngasentla, kulindeleke ukuba ziqhubele phambili imarike ye-graphite electrode ngexesha lexesha eliqikelelweyo.
Ummandla weAsia-Pacific uza kulawula iMarike
- Ummandla we-Asia-Pacific ulawula isabelo semarike yehlabathi. I-China ithatha isabelo esikhulu ngokwendlela yokusebenzisa kunye nomthamo wemveliso yee-electrodes ze-graphite kwimeko yehlabathi.
- Imiyalelo emitsha yomgaqo-nkqubo eBeijing nakwamanye amaphondo amakhulu kweli lizwe inyanzela abavelisi bentsimbi ukuba bavale umthamo weetoni zentsimbi ezizizigidi ezili-1.25 eziveliswa ngendlela enobungozi kokusingqongileyo ukuze kuveliswe umthamo omtsha weetoni zentsimbi ezizizigidi ezili-1. Ezi nkqubo ziye zaxhasa utshintsho lwabavelisi kwiindlela zemveli zokuvelisa intsimbi ukuya kwindlela ye-EAF.
- Ukwanda kwemveliso yezithuthi, kunye noshishino lokwakha izindlu olukhulayo, kulindeleke ukuba luxhase imfuno yasekhaya yee-alloys ezingezizo iintsimbi kunye nentsimbi, nto leyo enegalelo elihle ekukhuleni kwemfuno ye-graphite electrode kwiminyaka ezayo.
- Umthamo wangoku wemveliso yee-electrode ze-graphite ze-UHP eTshayina umalunga neetoni ezingama-50 amawaka ngonyaka. Imfuno yee-electrode ze-UHP eTshayina kulindeleke ukuba ibone ukukhula okukhulu kwixesha elide kwaye umthamo owongezelelweyo weetoni ezingaphezu kwama-50 amawaka amawaka zee-metric zee-electrode ze-graphite ze-UHP kulindeleke ukuba ubonwe ngamanqanaba alandelayo exesha lokuqikelela.
- Zonke ezi zinto zikhankanyiweyo apha ngasentla, kulindeleke ukuba zonyuse imfuno ye-graphite electrode kulo mmandla ngexesha lexesha eliqikelelweyo.
