HP GRAPHITE ELECTRODES – Bophara ba tsona bo tloha ho 200 mm ho isa ho 600 mm
TLHALOSO
Electrode ea graphite ea HP ke karolo e tsamaisang motlakase bakeng sa ho etsa tšepe ea lifono tsa arc tsa motlakase. E entsoe ka coke ea peterole, coke ea nale, pitch ea mashala 'me e hlahisoa ke letoto la lits'ebetso tse thata tsa tlhahiso. Methapo ea motlakase o phahameng e kenella ka har'a koung ea electrode ea graphite ka hare ho 'mele oa sebōpi. Sena se tla ntša matla a motlakase ka har'a sebōpi sa arc ho futhumatsa sebōpi.
Tlhoko ea li-electrode tse bophara bo boholo e ntse e eketseha ha boholo ba sebōpi sa EAF bo ntse bo eketseha. Li-electrode tsa graphite tse bophara ba 500 mm kapa 600 mm li se li tumme haholo lilemong tsa morao tjena.
TŠOBOTSI
Kalafo ea ho thibela oxidation bakeng sa bophelo bo bolelele.
Bohloeki bo phahameng, ho ba le bongata bo boholo, botsitso bo matla ba lik'hemik'hale.
Ho nepahala ho hoholo ha ho sebetsa, ho qeta hantle ha bokaholimo.
Matla a phahameng a mechini, khanyetso e tlase ea motlakase.
E hanela ho petsoha le ho taboha.
Ho hanyetsa ho hoholo ha oxidation le ho thothomela ha mocheso.
KOPO
Li-electrode tsa graphite li sebelisoa haholo bakeng sa tlhahiso ea litšepe tsa alloy, tšepe le thepa e 'ngoe e seng ea tšepe, jj.
Sebōpi sa motlakase sa DC.
Sebōpi sa arc sa motlakase sa AC.
Sebōpi sa arc se qoelitsoeng ka metsing.
