Elettrodu tal-grafita HP għall-Azzar
L-Introduzzjoni ta 'HP Graphite Electrode
Elettrodu tal-grafita ta 'qawwa għolja huwa prodott minn kokk tal-pitrolju b'kontenut baxx ta' kubrit (jew kokk tal-labra) bħala materja prima u asfalt tal-faħam bħala binder permezz ta 'kalċinazzjoni, tgħaffiġ, batching, għaġna, iffurmar, ħami, impregnazzjoni, rebaking, grafitizzazzjoni u makkinar.Il-proprjetajiet fiżiċi u mekkaniċi tiegħu huma ogħla minn elettrodu tal-grafita tal-qawwa regolari, bħal resistività baxxa u densità kbira ta 'kurrent.
L-Applikazzjoni ta 'HP Graphite Electrode
(1) Għat-tidwib ta 'l-azzar f'forn ta' l-ark elettriku/forn ladle
(2) L-elettrodu tal-grafita HP huwa prinċipalment użat fil-forn bl-ark elettriku għall-produzzjoni tal-azzar.Meta l-elettrodu tal-grafita qed jaħdem f'EAF, il-kurrent jiġi introdott mill-elettrodu tal-grafita fil-forn, u se jkun hemm sors ta 'sħana li huwa ġġenerat minn ark elettriku bejn it-tarf tal-elettrodu u l-ħlas tal-forn għat-tidwib.
(3) Għat-tidwib tal-kurundun fil-forn elettriku
(4) Użat għall-ipproċessar ta 'prodotti tal-grafita b'forma speċjali
Il-vojt tal-elettrodu tal-grafita jintuża wkoll biex jipproċessa diversi prod tal-grafita b'forma speċjali u griġjol tal-grafita, eċċ.
