1. Imfuno Ekhulayo Yentsimbi Esemgangathweni Ophezulu
Le yenye yezona zinto ziphambili ezikhuthaza ukukhula kwemarike yee-electrode zegrafiti. Uphuhliso olukhawulezileyo lwamashishini esinyithi afana nokwakha, iimoto, iziseko zophuhliso, i-aerospace kunye nokhuselo lwesizwe kukhokelele ekwandeni kwemfuno kunye nemveliso yesinyithi.
2. Isithando somlilo se-Electric Arc siyindlela eqhelekileyo yamaxesha
Ichatshazelwa lukhuseleko lokusingqongileyo kunye nokuguquguquka okuphezulu kwemveliso, inkqubo yokwenza intsimbi kumazwe asakhasayo iyatshintsha ukusuka kwi-blast furnace kunye ne-ladle furnace ukuya kwi-electric arc furnace (EAF). Ii-graphite electrodes zezona ziphambili zokusetyenziswa kwentsimbi ye-electric furnace, kwaye i-graphite electrodes ezifikelela kwi-70% zisetyenziswa ekwenzeni intsimbi ye-electric arc furnace. Uphuhliso olukhawulezileyo lwe-electric furnace lunyanzela ukuba amandla emveliso ye-graphite electrode anyuke.
3. Ii-Electrode zeGraphite zizinto ezisetyenziswayo
Ixesha lokusetyenziswa kwe-graphite electrode lidla ngokuba malunga neeveki ezimbini. Nangona kunjalo, umjikelo wokuveliswa kwee-graphite electrodes ngokubanzi uhlala iinyanga ezi-4-5. Ngexesha lokusetyenziswa, amandla okuvelisa e-graphite electrode kulindeleke ukuba ancitshiswe ngenxa yemigaqo-nkqubo yesizwe kunye nexesha lokufudumeza.
4. I-Needle Coke yodidi oluphezulu imfutshane kakhulu
I-Needle coke sisixhobo esibalulekileyo sokuvelisa ii-electrode ze-graphite. Yi-calcined petroleum coke (CPC) ebiza malunga ne-70% yeendleko zokufaka imveliso ye-graphite electrode. Ukunyuka kwamaxabiso okubangelwa linani elilinganiselweyo lokungeniswa kwe-needle coke sesona sizathu siphambili sokunyuka ngokuthe ngqo kwexabiso lee-electrode ze-graphite. Okwangoku, i-needle coke ikwasetyenziswa ekuveliseni izixhobo ze-electrode kwiibhetri ze-lithium kunye namashishini eenqwelo moya. Olu tshintsho kubonelelo kunye nemfuno lwenza ixabiso le-graphite electrode lingabi nakuphepheka.
5. Iimfazwe zorhwebo phakathi koqoqosho olukhulu lwehlabathi
Oku kukhokelele ekwehleni okukhulu kokuthunyelwa kwentsimbi eTshayina, kwaza kwanyanzela amanye amazwe ukuba anyuse amandla okuvelisa. Kwelinye icala, kukwakhokelele ekwandeni komthamo wokuthunyelwa kwee-electrode ze-graphite eTshayina. Ukongeza, i-United States inyuse irhafu kwiimpahla ezithunyelwa eTshayina, nto leyo eye yanciphisa kakhulu ixabiso lee-electrode ze-graphite zaseTshayina.
