SHARAXAAD
Elektroodka UHP graphite waxaa loo isticmaalaa dib-u-warshadaynta birta warshadaha foornada korantada. Waxyaabaha ugu muhiimsan waa coke irbad qiimo sare leh oo laga sameeyay batrool ama daamur dhuxul ah. Elektroodka garaafiga waxaa lagu dhammeeyaa qaab dhululubo ah waxaana lagu farsameeyaa meelo dun ah oo dhinac walba ah. Sidan, elektroodka garaafiga waxaa lagu ururin karaa tiir elektroodh ah iyadoo la adeegsanayo ibta elektroodka.
Si loo daboolo shuruudaha hufnaanta shaqada oo sareysa iyo kharashka guud ee hooseeya, foornooyinka qaansada ee awoodda badan leh ayaa sii kordhaya. Sababtaas awgeed, elektroodhada garaafka UHP ee dhexroorkoodu ka badan yahay 500 mm ayaa suuqa xukumi doona.
ASTAAMAHA
U adkeysan kara durdurro waaweyn, heerka dheecaanka oo sareeya.
Xasillooni cabbir wanaagsan, ma fududa in la beddelo.
U adkaysi u leh dildilaaca iyo xoqidda.
Iska caabin sare oo ku wajahan oksaydhka iyo shoogga kulaylka.
Awood farsamo oo sareysa, iska caabin koronto oo hooseysa.
Saxnaanta mashiinka sare, dhammaystirka dusha sare oo wanaagsan.
CODSIGA
Elektroodhada graphite waxaa si weyn loogu isticmaalaa soo saarista biraha daawaha, birta iyo walxaha kale ee aan birta ahayn, iwm.
Foorno koronto oo DC ah.
Foornada korantada ee AC-ga.
Foorno qaanso ah oo hoos u dhacday.
