Product Description
UHP Graphite Electrode
UHP Graphite Electrode stands for Ultra High Power Graphite Electrode. It is a type of high-performance electrode used in electric arc furnaces for steel production. UHP graphite electrodes have low electrical resistance, high thermal conductivity, and good mechanical strength, which makes them ideal for use in high-temperature and high-power applications. They are made from premium quality needle coke and are used in the production of high-quality steel products.
Features of UHP (Ultra High Power) Graphite Electrodes:
Higher purity, higher density and better chemical stability;
Low coefficient of thermal expansion, resistance to cracking, spalling and thermal shock;
Higher mechanical strength and lower resistivity;
Higher processing precision and better surface finish;
Advanced antioxidant treatment process, lower consumption and longer service life.
Application
Conventional power (RP) graphite electrodes are suitable for all kinds of AC and DC conventional power arc furnaces, resistance furnaces, mineral heat furnaces for melting all kinds of alloy steels, metals, non-metals and so on.
