Zisebenza njani iielectrode zegraphite?

Masithethe Zisebenza njani iielectrode zegraphite? Inkqubo yokwenziwa kwe-electrode yegraphite kwaye Kutheni kufuneka ii-electrode zegraphite zitshintshwe?
1. Zisebenza njani iielectrode zegraphite?
I-electrodes iyingxenye yesivalo sesithando somlilo kwaye ihlanganiswe kwiikholomu. Umbane ke udlula kwii-electrode, wenze i-arc yobushushu obugqithisileyo obunyibilikisa intsimbi endala.
Ii-electrode zihanjiswa ezantsi kwi-scrap ngexesha lokunyibilika. Emva koko i-arc iveliswa phakathi kwe-electrode kunye nesinyithi. Ngokuqwalasela inkalo yokukhusela, i-voltage ephantsi ikhethiwe kule nto. Emva kokuba i-arc ikhuselwe ngama-electrodes, i-voltage iyanda ukukhawulezisa inkqubo yokunyibilika.
2. inkqubo yokuvelisa i-electrode yegraphite
I-electrode yegraphite yenziwe ikakhulu nge-petroleum coke kunye nenaliti ye-coke, kwaye ibhitumene yamalahle isetyenziswa njenge-binder. Yenziwa ngokubala, ukudibanisa, ukuxova, ukucinezela, ukuqhotsa, igraphitization kunye nomatshini. Kukukhupha amandla ombane ngendlela ye-arc yombane kwisithando sombane sombane. Umqhubi oshushu kwaye unyibilike umrhumo unokwahlulwa ube yi-electrode yegraphite yamandla aqhelekileyo, i-electrode ephezulu yegraphite kunye ne-ultra high power graphite electrode ngokwesalathisi somgangatho wayo.

3. Kutheni i-electrode yegraphite ifuna ukutshintshwa?
Ngokomgaqo wokusetyenziswa, kukho izizathu ezininzi zokutshintsha i-electrode yegraphite.
• Ukuphela kokusetyenziswa: Oku kubandakanya ukuthotywa kwemathiriyeli yegraphite ebangelwa liqondo lobushushu eliphezulu le-arc kunye nokulahleka kokusabela kweekhemikhali phakathi kwe-electrode kunye nentsimbi etyhidiweyo kunye ne-slag. Izinga lokunciphisa ubushushu obuphezulu ekupheleni ikakhulu kuxhomekeke kubuninzi bangoku obuhamba nge-electrode; kwakhona ezinxulumene nobubanzi becala le-electrode emva kwe-oxidation; Ukuphela kokusetyenziswa kwakhona kuhambelana nokuba kufakwe i-electrode emanzini ensimbi ukunyusa i-carbon.
• I-oxidation yeLateral: Ukwakhiwa kweekhemikhali ze-electrode yi-carbon, i-Carbon iya ku-oxidize ngomoya, umphunga wamanzi kunye ne-carbon dioxide phantsi kweemeko ezithile, kwaye ubungakanani be-oxidation yecala le-electrode lihambelana nenani leyunithi ye-oxidation kunye ne-exposure area. Ngokuqhelekileyo, i-Electrode side oxidation I-akhawunti malunga ne-50% yokusetyenziswa kwe-electrode iyonke. Kwiminyaka yakutshanje, ukuze kuphuculwe isantya sokunyibilikisa kwesithando sombane, ukuphindaphindwa kokusebenza kokuvuthela ioksijini kwanda, ukulahleka kwe-oxidation ye-electrode kwanda.
• Ilahleko eshiyekileyo: Xa i-electrode isetyenziswa ngokuqhubekayo ekudibaneni kwee-electrode eziphezulu nangaphantsi, icandelo elincinane le-electrode okanye i-joint ivalwe ngenxa yokuncipha kwe-oxidative yomzimba okanye ukungena kweentanda.
• Ukuxobulwa nokuwa komphezulu: Isiphumo sokunganyangeki kakuhle kwe-electrode ngokwayo ngexesha lenkqubo yokunyibilikisa. Bandakanya umzimba we-electrode owaphukileyo kunye nengono eyaphukileyo. I-Electrode eyaphukileyo ihambelana nomgangatho kunye nokulungiswa kwe-graphite electrode kunye nengono, ekwanxulumene nokusebenza kwentsimbi.
