550mm koronto garaafeed sare
Electrode graphite HP wuxuu inta badan ka samaysan yahay coke petroleum iyo coke irbadda, Waxay awood u leedahay inay qaado cufnaanta hadda jirta 18-25A/cm2.Waxaa loogu talagalay samaynta birta foornada korontada ku shaqeysa ee awoodda sare leh.
Hababka casriga ah ee birta samaynta inta badan waxa ka mid ah samaynta birta samaynta beddelka iyo foornada korontadaFarqiga aasaasiga ah ee u dhexeeya habka birta foornada korontada iyo habka birta samaynta beddelka ayaa ah in habka birta foornada korontada ay u isticmaasho tamarta korantada sida il kulaylka, iyo habka birta foornada ee korantada ayaa ah tan ugu badan ee la isticmaalo.
Bir-samaynta EAF waxay ku salaysan tahay qaanso koronto oo ay dhaliso qulqulka u dhexeeya electrode-ka iyo kharashka, kaas oo tamarta korantada u beddela tamarta kulaylka ee iftiinka arc, oo u adeegsada ficilka tooska ah ee shucaaca iyo arc si uu u kululeeyo oo u dhalaaliyo birta iyo boodhka si ay u dhalaaliyaan. birta iyo Alloys ka kooban oo kala duwan.

Halabuurka electrode graphite
1.Coke batroolku waa madow iyo dalool, kaarboonku waa ka samaysanka ugu weyn, waxa ku jira dambaskuna aad buu u hooseeyaa, guud ahaan waxa ka hooseeya 0.5%.
Coke batroolka waxaa loo qaybin karaa laba nooc oo kookaha ceeriin ah iyo kookaha calcined iyadoo loo eegayo heerkulka daaweynta kulaylka.Midka hore waxa uu ka kooban yahay xaddi badan oo ah walxo isbedbeddelaya oo leh awood farsamo oo hooseeya.Coke-ka calcined waxaa lagu helaa iyadoo la xisaabinayo kookaha ceeriin.
Coke batroolka waxaa loo qaybin karaa kookaha baaruudda sare (oo leh maaddo baaruud ah oo ka sarreysa 1.5%), kookaha baaruud dhexdhexaadka ah (oo leh maaddo baaruud ah 0.5%-1.5%), iyo kookaha baaruudda hoose (oo leh maaddo baaruud ah oo ka hooseeya 0.5%) marka loo eego heerka baaruudda.Electrodes-ka graphite iyo alaabada kale ee garaafka macmalka ah ayaa guud ahaan la soo saaraa iyadoo la isticmaalayo kookaha sulfur hoose.
2.Needle coke waa nooc ka mid ah coke-tayo sare leh oo leh texture fiber cad, gaar ahaan iskudhafka ballaarinta kulaylka hooseeya iyo garaafka fudud.Sidaa darteed, kookaha cirbadaha ayaa ah sheyga muhiimka ah ee soo saarista tamarta sare ama ultra-high-power graphite electrodes oo leh iska caabin hooseeya, iskudar balaadhinta kulaylka yar, iyo caabbinta shoogga kulaylka wanaagsan.
Dhererka 3.Coal waa mid ka mid ah wax soo saarka ugu muhiimsan ee daamurka dhuxusha ka dib farsamaynta qoto dheer.Waa isku dhafka hydrocarbons badan.Dhererka dhuxusha waxaa loo isticmaalaa sida wax lagu xidho iyo walxaha uurjiifka ah.Wax qabadkeedu wuxuu saameyn weyn ku leeyahay tayada electrodes graphite.
