Product Description

Graphite electrode is mainly used in arc steel-making furnace, ore-smelting electric furnace, resistance furnace, etc., with good thermal conductivity, high temperature resistance, is widely used in metallurgy, machinery, electrical, chemical, textile, national defense and other industrial sectors. Graphite electrode is generally divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode.
