Dettalji tal-Prodotti
L-elettrodi jġorru l-elettriku li jsaħħan il-fran bl-ark elettriku, il-fran tal-azzar tal-maġġoranza l-kbira. Huma magħmulin minn kokk taż-żejt wara li jitħallat maż-żift taż-żejt, estruż u ffurmat, imbagħad moħmi biex sinterizzat, u mbagħad grafitizzat billi jissaħħan 'il fuq mit-temperatura (3000 °C) li jikkonverti l-karbonju għal grafita. Jistgħu jvarjaw fid-daqs sa 11 pied twil u 30 pulzieri fid-dijametru.
Użu
- 01 Proporzjon dejjem jikber ta 'azzar globali huwa magħmul bl-użu ta' fran bl-ark elettriċi
- 02 Il-forn tal-ark elettriku innifsu qed isir aktar effiċjenti u jagħmel aktar azzar għal kull tunnellata ta 'elettrodu
