Masithethe malunga Zisebenza njani ii-electrode ze-graphite? Inkqubo yokwenziwa kwee-electrode ze-graphite kwaye Kutheni ii-electrode ze-graphite kufuneka zitshintshwe?
1. Zisebenza njani ii-electrode zegrafiti?
Ezi electrode ziyinxalenye yesiciko sesithando somlilo kwaye zidityaniswe zibe ziintsika. Umbane emva koko udlula kwii-electrode, wenze umjikelo wobushushu obukhulu onyibilikisa intsimbi elahliweyo.
Ii-electrode zisiwa phantsi kwi-scrap ngexesha lokunyibilika. Emva koko i-arc iveliswa phakathi kwe-electrode kunye nesinyithi. Ngokuqwalasela icandelo lokukhusela, kukhethwa i-voltage ephantsi koku. Emva kokuba i-arc ikhuselwe zii-electrodes, i-voltage iyandiswa ukuze kukhawuleziswe inkqubo yokunyibilika.
2. Inkqubo yokuvelisa i-graphite electrode
I-electrode yegrafiti yenziwe kakhulu nge-petroleum coke kunye ne-needle coke, kwaye i-coal bitumen isetyenziswa njenge-binder. Yenziwa ngoku-calcination, compounding, kneading, pressing, roasting, graphitization kunye ne-machining. Yenzelwe ukukhupha amandla ombane ngendlela ye-electric arc kwisithando sombane se-arc. I-conductor efudumeza kwaye inyibilikise itshaja inokwahlulwa ibe yi-common power graphite electrode, i-high power graphite electrode kunye ne-ultra high power graphite electrode ngokwe-quality index yayo.
3. Kutheni kufuneka kutshintshwe ii-electrode zegrafiti?
Ngokomgaqo wokusetyenziswa, kukho izizathu ezahlukeneyo zokutshintsha ii-electrode ze-graphite.
• Ukusetyenziswa kokugqibela: Oku kuquka ukufakelwa kwezinto zegrafiti ezibangelwa bubushushu obuphezulu be-arc kunye nokulahleka kwempendulo yeekhemikhali phakathi kwe-electrode kunye nentsimbi enyibilikisiweyo kunye ne-slag. Izinga lokufakelwa kobushushu obuphezulu ekupheleni lixhomekeke kakhulu kubuninzi bangoku obudlula kwi-electrode; likwanxulumene nobubanzi becala le-electrode emva kwe-oxidation; Ukusetyenziswa kokugqibela kukwanxulumene nokuba kufuneka kufakwe i-electrode emanzini entsimbi ukuze kwandiswe ikhabhoni.
• I-oxidation esecaleni: Ulwakhiwo lweekhemikhali ze-electrode yi-carbon, i-Carbon iya ku-oxidation ngomoya, umphunga wamanzi kunye ne-carbon dioxide phantsi kweemeko ezithile, kwaye ubungakanani be-oxidation kwicala le-electrode buhambelana nesantya se-oxidation yeyunithi kunye nendawo yokuvezwa. Ngokwesiqhelo, i-oxidation esecaleni kwe-Electrode ibandakanya malunga ne-50% yokusetyenziswa kwe-electrode iyonke. Kwiminyaka yakutshanje, ukuze kuphuculwe isantya sokunyibilikisa kwesithando sombane, i-frequency yokusebenza kokuvuthela i-oxygen iyanda, ilahleko ye-oxidation ye-electrode iyanda.
• Ukulahleka kwentsalela: Xa i-electrode isetyenziswa rhoqo kwindawo ekudibana kuyo i-electrode ephezulu nesezantsi, icandelo elincinci le-electrode okanye ijoyinti liyasuswa ngenxa yokuncitshiswa kwe-oxidative emzimbeni okanye ukungena kwemifantu.
• Ukuxobuka nokuwa komphezulu: Isiphumo sokunganyamezelani kakuhle kobushushu be-electrode ngokwayo ngexesha lenkqubo yokunyibilikisa. Bandakanya umzimba we-electrode ophukileyo kunye ne-nipple ephukileyo. I-electrode ephukileyo inxulumene nomgangatho kunye nokulungiswa kwe-graphite electrode kunye ne-nipple, ikwanxulumene nokusebenza kokwenziwa kwentsimbi.
