Imakethi yehlabathi yegraphite electrode ixabisa i-9.13 yeebhiliyoni zeedola zaseMelika ngo-2018 kwaye kulindeleke ukuba ifikelele kwi-16.48 yeebhiliyoni zeedola zaseMelika ngo-2025, ngesantya sokukhula sonyaka esisi-8.78% ngexesha loqikelelo.
Ngokunyuka kwemveliso yentsimbi kunye nokwenziwa kweziseko ezingundoqo zale mihla, imfuno yobunjineli kunye nemathiriyeli yokwakha iyaqhubeka nokukhula, ezizezinye zezinto ezibalulekileyo eziqhuba ukukhula kwemarike yegraphite electrode yehlabathi.

I-electrode yegraphite zizinto zokufudumeza ezisetyenziswa kwiziko lombane le-arc ukwenza intsimbi kwi-scrap, iimoto ezindala kunye nezinye izixhobo.Ii-electrode zinika ubushushu kwintsimbi elahliweyo ukuyinyibilikisa ukuvelisa intsimbi entsha.Iziko zombane ze-arc zisetyenziswa kakhulu kumashishini okuvelisa intsimbi kunye ne-aluminiyam kuba zixabiso eliphantsi ukwenza.Iielectrode zegraphite zinokudityaniswa zibe ziisilinda kuba ziyinxalenye yesigqubuthelo somlilo sombane.Xa amandla ombane anikeziweyo edlula kula ma-electrode egraphite, i-arc yombane eyomeleleyo yenziwa, inyibilikisa intsimbi ye-scrap.Ngokwemfuno yobushushu kunye nobukhulu beziko lombane, ii-electrode zobungakanani obahlukeneyo zingasetyenziswa.Ukuze kuveliswe i-toni ye-1 yentsimbi, malunga ne-3 kg ye-electrode yegraphite efunekayo.Ekwenziweni kwentsimbi, igraphite iyakwazi ukumelana namaqondo obushushu aphezulu, ngoko ke ubushushu bencam ye-electrode bufikelela kuma-3000 degrees Celsius.Iinaliti kunye nepetroleum coke zezona zinto zisetyenziswayo ukwenza i-graphite electrode.Kuthatha iinyanga ezintandathu ukwenza i-electrode yegraphite, emva koko iinkqubo ezithile, kuquka ukubhaka nokubhaka kwakhona, zisetyenziselwa ukuguqula i-coke ibe yigraphite.I-electrode yegraphite ilula ukwenza ngaphezu kwee-electrode zethusi, kwaye isantya sokuvelisa sikhawuleza ngenxa yokuba ayifuni iinkqubo ezongezelelweyo ezifana nokugaya ngesandla.
Ulwakhiwo lwemakethi ye-graphite electrode, ukwanda kwemfuno yentsimbi kwioyile negesi nakwimizi-mveliso yeemoto kulindeleke ukuba ikhuthaze uphuhliso lwemakethi yegraphite electrode.Ngaphezulu kwe-50% yentsimbi yehlabathi eveliswayo isetyenziswa kumashishini okwakha kunye nezakhiwo.Ingxelo ibandakanya abaqhubi, izithintelo, amathuba, kunye neendlela zamva nje eziye zanegalelo ekukhuleni kweemarike ngexesha lokuhlalutya.Ingxelo ihlalutya ngokweenkcukacha iintlobo kunye nokusetyenziswa kokwahlulwa kwemimandla.
I-electrode yegraphite yenye yabaqhubi, kwaye yinxalenye eyimfuneko kwinkqubo yokwenza intsimbi.Kule nkqubo, isinyithi esilahliweyo siyanyibilika kwisithando sombane se-arc kwaye siphinde sisetyenziswe.I-electrode yegraphite engaphakathi kwiziko ngokwenene yayinyibilikisa intsimbi.IGraphite ine-conductivity ephezulu ye-thermal, kwaye ishushu kakhulu kunye nefuthe elinamandla.Inokumelana okuphantsi, oku kuthetha ukuba inokuqhuba imisinga emikhulu efunekayo ukunyibilikisa isinyithi.I-electrode yegraphite isetyenziswa ikakhulu kwiziko lombane le-arc (EAF) kunye ne-ladle furnace (LF) yokuvelisa intsimbi, i-ferroalloy, i-silicon yentsimbi ye-graphite electrode isetyenziswa kwisithando sombane se-arc (EAF) kunye ne-ladle furnace (LF) yokuvelisa intsimbi, imveliso ye-ferroalloy, i-silicon yesinyithi Ukuveliswa kunye nenkqubo yokunyibilikisa
Ingxelo yentengiso yegraphite electrode yehlabathi ibandakanya abadlali abaziwayo abanje ngeGrafTech, iFangda Carbon China, iSGL Carbon yaseJamani, iShowa Denko, iGraphite India, iHEG India, iTokai Carbon Japan, iNippon Carbon Japan, SEC Carbon Japan, njl.njl. American GrafTech, Fangda ICarbon China kunye neGraphite India zinomthamo wemveliso we-454,000 yeetoni.
