Overview：

The Ultra High Power(UHP) Graphite Electrodes produces by 100% high quality imported needle coke,advanced production equipment and technology,and is produced in strict accordance with the world class standard,the Ultra-High Power(UHP) Graphite Electrode has lower resistivity,better electrode conductivity and higher mechanical strength.

Ultra high power graphite electrodes are advanced materials crucial for the steelmaking industry, particularly in electric arc furnace (EAF) steel production. These electrodes are designed to withstand extremely high temperatures and electrical currents, making them ideal for use in high-power EAFs. Ultra-high-power graphite electrodes play a vital role in the steelmaking process by enabling efficient generation and transfer within the arc furnace, ultimately leading to improved productivity and cost-effectiveness. Their exceptional thermal conductivity, mechanical strength, and resistance to thermal shock make them indispensable for modern steelmaking operations aiming for high performance and energy efficiency. As a result, the demand for ultra-high-power graphite electrodes continues to grow in tandem with the expansion of the global steel industry.

Description：

Allows the use of current density greater than 25A/cm2,mainly used for ultra-high power steel making electric arc furnace.

UHP graphite electrode is used for the recycling of steel in the electric arc furnace industry. Its main ingredient is high-value needle coke which is made from either petroleum or coal tar. Graphite electrodes are finished with a cylinder shape and machined with threaded areas at each end. In this way, the graphite electrodes can be assembled into an electrode column using electrode nipple.
