Waa maxay sababta loo isticmaalo graphite electrodes? Faa'iidooyinka iyo cilladaha electrode graphite

Electrode graphite waa qayb muhiim ah oo ka mid ah EAFsteelmaking, laakiin waxay kaliya ku xisaabtamaysaa qayb yar oo ah kharashka birta samaynta. Waxay qaadanaysaa 2 kg oo ah graphite electrode si loo soo saaro tan oo bir ah.

Waa maxay sababta loo isticmaalo graphite electrodes?

Electrode graphite waa qalabka ugu muhiimsan ee kirishbooyada kuleyliyaha ee foornada arc. EAFs habka dhalaalidda qashinka baabuurta duugga ah ama qalabka guriga si loo soo saaro bir cusub.
Qiimaha dhismaha foornada arc ee korontada ayaa ka hooseeya tan foornada qaraxa ee dhaqameed. Foornooyinka qarxa ee dhaqameedku waxay ka sameeyaan bir birta waxayna u isticmaalaan dhuxusha kareysa shidaal ahaan. Si kastaba ha ahaatee, kharashka biraha samaynta ayaa sarreeya, wasakhowga deegaankuna waa halis. Si kastaba ha ahaatee, EAF waxay isticmaashaa birta qashinka ah iyo korontada, kuwaas oo si dhib leh u saameeya deegaanka.
Electrode graphite waxa loo isticmaalaa in lagu ururiyo electrode iyo daboolka foornada oo dhan, iyo graphite electrode waa la hawlgalin karaa kor iyo hoos. Hadda waxa uu maraa koronto-dhaliyaha, isaga oo samaynaaya qaanso heerkul sare leh oo dhalaalinaysa birta qashinka ah. Electrodes-ku waxay noqon karaan ilaa 800mm(2.5ft) dhexroor ah iyo ilaa 2800mm(9ft) oo dherer ah. Miisaanka ugu badan ayaa ka badan laba metric ton.

Isticmaalka korantada graphite

Waxay qaadataa 2 kiiloogaraam (4.4 rodol) ee elektrodes garaafyada si loo soo saaro tan oo bir ah.

Heerkulka korantada graphite

Cidhifka korantada ayaa gaari doonta 3,000 darajo Celsius, kala bar heerkulka sare ee qorraxda. Electrode-ku wuxuu ka samaysan yahay graphite, sababtoo ah graphite kaliya ayaa u adkeysan kara heerkulka sare.
Kadibna foornada dhinaceeda u rog oo birta dhalaalaysa ku shub foosto waaweyn. Dabadeedna birta dhalaalaysa waxay geynaysaa kasarka warshadda birta, taas oo qashinka dib loo warshadeeyay u beddelaysa badeeco cusub.

Electrode graphite waxa uu cunaa koronto

Nidaamku wuxuu u baahan yahay koronto ku filan si ay u koronto magaalo ay ku nool yihiin 100,000 oo qof. Foornada koronto ee casriga ah, dhalaalid kastaa waxay caadi ahaan qaadataa 90 daqiiqo waxayna soo saari kartaa 150 tan oo bir ah, oo ku filan in la sameeyo 125 baabuur.

Wax cayriin

Coke irbadu waa alaabta ugu muhiimsan ee electrodes, kaas oo qaata ilaa saddex ilaa lix bilood si ay u soo saaraan. Nidaamku wuxuu ku lug leeyahay dubay iyo dib u soo celinta si kookaha loo rogo garaaf, ayuu yiri soo saaraha.
Waxaa jira coke cirbad ku salaysan batroolka iyo coke irbad dhuxul ku salaysan, labadaba waxaa loo isticmaali karaa in lagu soo saaro electrodes graphite. "Pet Coke" waa wax ka soo baxa habka sifaynta batroolka, halka dhuxusha-ilaa-coke laga sameeyay taamurka dhuxusha ee dhaca inta lagu jiro habka wax soo saarka kookaha.
