Habka Wax-soo-saarka ee Graphite Electrode
Graphite electrode waa nooc ka mid ah heerkulka sare u adkaysta graphite walxaha soo saaray iyadoo la isticmaalayo coke batroolka, coke irbadda sida wadar ahaan, asphalt dhuxusha sida xidhe, ka dib markii taxane ah oo geedi socodka sida qaso, qaabaynta, dubay, quusin, graphitization iyo farsamaynta farsamada.
Habka ugu muhiimsan ee wax soo saarka ee electrode graphite waa sida soo socota:
(1) Calcination.Coke batroolka ama kookaha asphalt waxay u baahan yihiin in la been-abuuro, heerkulka calcination-kuna waa inuu gaaro 1300 ℃, si si buuxda looga saaro waxyaabaha kacsan ee ku jira alaabta ceeriin ee kaarboon, loona hagaajiyo cufnaanta dhabta ah, xoogga farsamada iyo korantada korantada ee kookaha.
(2) burburin, baaris, iyo maaddooyin.Walxaha cayriin ee kaarboonka la kariyey waa la jebiyey waxaana lagu baadhay qaybo wadareed oo cabbirka la cayimay, qayb ka mid ah kookaha ayaa lagu miiray budo fiican, isku dhafka qallalanna waxaa la isugu geeyey hab waafaqsan qaabka.
(3) Isku qas.Xaaladda kuleylka, isku dhafka qallalan ee qiyaasta ee qaybo kala duwan ayaa lagu qasi karaa xiraha tirada, isku dhafan oo la cajiimay si loo farsameeyo koollada caagga ah.
(4) qaabaynta, hoos ficil cadaadiska dibadda (extrusion samaynta) ama hoos ficil gariir soo noqnoqda sare (samaynta gariir) in la cadaadiyo koollada galay qaab gaar ah iyo cufnaanta sare ee electrode cayriin (billet).
(5) Duubista.Electrode-ka cayriin waxa lagu dhejiyaa foorno duban oo gaar ah, budada kookaha ee macdanaha ah ayaa la buuxiyey oo lagu daboolay korantada ceeriin.Heerkulka sare ee wakiilka isku xidhka ee ku saabsan 1250 ℃, dubista kaarboonka ayaa la sameeyaa.
(6) Xumaan.Si loo hagaajiyo cufnaanta iyo xoogga farsamada ee alaabta korantada, korantada dubanaysa waxaa lagu shubaa qalabka koronta sare, iyo asphalt wakiilka dareeraha dareeraha ah ayaa lagu cadaadiyaa godka hawada ee electrode.Ka dib dhexgalka, dubaydu waa in la sameeyaa hal mar.Marka loo eego shuruudaha waxqabadka badeecada, mararka qaarkood impregnation iyo dubista sare waa in lagu celiyaa 23 jeer.
(7) garaafaynta.Elektroodka kaarboonka ee la dubay waxaa lagu shubaa foornada garaafka, oo lagu daboolay walxaha dahaarka.Adigoo isticmaalaya habka kuleyliyaha ee koronto toos ah si loo soo saaro heerkul sare, korantada kaarboonka waxaa loo rogaa electrode garaaf ah oo leh qaab dhismeedka graphite ee heerkulka sare ee 2200 ~ 3000 ℃.
(8) mishiinada.Marka loo eego shuruudaha isticmaalka, garaafyada elektiroonigga ah ee bannaan ee leexashada, dusha sare ee dhamaadka fidsan iyo godadka isku xidhka isku xidhka, iyo isku xidhka xidhiidhka.
(9) Electrode graphite waa in si sax ah loo xirxiraa ka dib marka la gudbiyo baaritaanka oo loo diro isticmaalaha.
