Habka yaraynta isticmaalka korantada
Sanadihii la soo dhaafay, iyada oo horumarinta xoogga leh ee warshadaha birta foornada korontada ee Shiinaha, iyo sidoo kale shuruudaha badbaadinta tamarta iyo khubarada dhimista isticmaalka iyo culimada dalka iyo dibadda soo gabagabeeyo qaar ka mid ah habab waxtar leh sida soo socota:
Habka 1.Anti-oxidation ee biyaha buufinta graphite electrode
Iyada oo loo marayo cilmi-baaris tijaabo ah, ku buufinta ka-hortagga-oxidation-ka ee dusha sare ee korantada ayaa si aad ah u caddaysay joojinta oksaydhka dhinaca ee korantada graphite, iyo awoodda ka-hortagga oksaydhka ayaa kordhay 6-7 jeer. Isticmaalka habkan ka dib, isticmaalka korantada ayaa hoos ugu dhacay 1.9-2.2kg oo dhalaalay tan oo bir ah.
2. Electrode godan
Sannadihii u dambeeyay, Galbeedka Yurub iyo Iswidhan waxay bilaabeen inay isticmaalaan koronto-dhal ah soo saarista foornada ferroalloy ore. Electrodes godan, qaabka dhululubada, guud ahaan waa madhan gudaha oo ay ku xidhan yihiin gaas aan shaqaynayn. Godannimada awgeed, xaaladaha dubista way fiicnaanayaan oo waxay ka dhigaan awoodda korantada mid sare. Guud ahaan, waxay badbaadin kartaa electrodes 30% -40%, ilaa 50% ugu badnaan.
3.DC foornada arc
Foornada dabka ee DC waa nooc cusub oo foorno koronto ah oo dhalaalisa oo dhowaan laga sameeyay adduunka sannadihii u dambeeyay. Laga soo bilaabo xogta la daabacay ee dibadda, DC foornada arc waa mid ka mid ah farsamooyinka ugu waxtarka badan ee lagu yareeyo isticmaalka korantada. Guud ahaan, isticmaalka korantada waxaa lagu dhimi karaa qiyaastii 40% ilaa 60%. Sida laga soo xigtay warbixinnada, isticmaalka graphite electrode ee foornada korontada ee baaxadda weyn ee DC ayaa hoos loo dhigay 1.6kg/t.
4.Electrode technology daahan dusha sare
Tiknooloojiyada dahaarka Electrode waa tignoolajiyad fudud oo wax ku ool ah si loo yareeyo isticmaalka korantada, guud ahaan waxay yarayn kartaa isticmaalka korantada ilaa 20%. Maaddooyinka daahan elektiroonigga ah ee sida caadiga ah loo isticmaalo waa aluminium iyo walxo dhoobo kala duwan, kuwaas oo leh iska caabin oksaydhyo xoog leh heerkul sare waxayna si wax ku ool ah u yareeyn kartaa isticmaalka oksaydhka ee dusha dhinaca korantada. Habka dahaarka electrode inta badan waa by buufin iyo shiidi, iyo habka ay u fudud oo fudud in la isticmaalo. Waa habka ugu badan ee loo isticmaalo ilaalinta korantada.
5.Elected-ka la dajiyay
Ku dhex rid electrodes xal kiimikaad si ay u keento isdhexgalka kiimikaad ee u dhexeeya dusha elektiroonigga ah iyo wakiilada si loo hagaajiyo caabbinta korantada ee oksaydhka heerkulka sare. Electrodes-ka noocaan ah wuxuu yarayn karaa isticmaalka korantada qiyaastii 10% ilaa 15%.
