UHP graphite electrode 350mm

Product Description

UHP graphite electrode 350mm is made from domestic petroleum coke and high-quality imported needle coke.

It is divided into regular power, high power, super high power, ultra-high power.

It is diameter ranges from 200 mm to 600mm.The height is between 1500 and 2400mm.

It has a round shape and a square shape.

Raw Material:

The regular power graphite electrode is made from petroleum coke with a little pitch

The high-power graphite electrode is made from 70% petroleum coke and 30% imported needle coke

The ultra-high-power graphite electrode is made from 100% imported needle coke

Characteristics of graphite electrode:

l low electric resistance

l good electric and thermal conductivity

l high oxidation resistance

l greater resistance to thermal and mechanical shock

l high mechanical strength

l high machining accuracy

Application

It is widely used in arc furnace steelmaking.

It is used in the mine thermoelectric furnace for the production of ferroalloy, pure silicon, yellow phosphorus, copper ice, calcium carbide, etc.

It is used in resistance furnace. Graphite furnace, melting glass furnace and electric furnace for producing silicon carbide.
