UHP ultra high power graphite electrode
UHP graphite electrodes are mainly used in ultra-high arc furnaces with current density greater than 25 A/CM2.
Description
UHP graphite electrode is used for steel recovery in the electric arc furnace industry. Its main component is high-value needle coke made from petroleum or coal tar. The graphite electrode is finished in a cylindrical shape and processed with threaded areas at both ends. In this way, the graphite electrode can be assembled into the electrode column using an electrode joint.
In order to meet the requirements of higher working efficiency and lower total cost, large-capacity ultra-high arc furnaces are becoming more and more popular. Therefore, UHP graphite electrodes with a diameter of more than 500 mm will dominate the market.
Features
Withstands large currents, high discharge rate.
Good dimensional stability, not easily deformed.
Resists cracking and peeling.
High resistance to oxidation and thermal shock.
High mechanical strength, low electrical resistance.
High processing accuracy, good surface.
Applications
Graphite electrodes are widely used in the production of alloy steel, metals and other non-metallic materials, etc. DC
Arc furnace.
AC arc furnace.
Submerged arc furnace.
Steel furnace.
Surface Quality
There should be less than two defects or holes on the electrode surface, the maximum size of which is mentioned in the figure below.
There should be no transverse cracks on the electrode surface. For longitudinal cracks, the length should be less than 5% of the electrode circumference and the width should be 0.3 to 1.0 mm.
The width of the black area on the electrode surface should be less than 1/10 of the electrode circumference and the length should be less than 1/3 of the electrode.
