Maelezo ya Bidhaa
Elektrodi hubeba umeme unaopasha joto matanuri ya arc ya umeme, tanuu nyingi za chuma. Hutengenezwa kutoka kwa mafuta ya petroli baada ya kuchanganywa na lami ya petroli, kutolewa nje na kuunda umbo, kisha kuoka ili kuoka, na kisha kuchorwa kwa kuipasha joto zaidi ya (3000 °C) ambayo hubadilisha kaboni hadi grafiti. Wanaweza kutofautiana kwa ukubwa hadi urefu wa futi 11 na kipenyo cha inchi 30.
Matumizi
- 01 Sehemu inayoongezeka ya chuma cha kimataifa hufanywa kwa kutumia tanuu za arc za umeme
- 02 Tanuru ya arc ya umeme yenyewe inapata ufanisi zaidi na kutengeneza chuma zaidi kwa tani ya electrode
