UHP ultra-high power Graphite Electrode 450-700mm For Steel smelting plant
Ultra-high power UHP graphite electrodes serve as electrodes in electric arc furnaces, generating high-temperature arcs to melt scrap steel, iron, or other metal raw materials for the production of new alloys and metals
Graphite electrode brief introduction
Graphite electrode is made from domestic first-class petroleum coke and high quality needle coke and are widely used in electric arc furnaces for the production of alloy steels, metal, and other nonmetallic materials, etc. The Graphite electrodes include regular power, high power, ultra-high power, and square electrodes. The range of diameters covers from 250mm to 700mm.
Our products have the following characteristics: low electric resistivity, good electrical and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, and high machining accuracy.
Application
Graphite electrodes are mainly used in electric arc furnace steelmaking, the working principle of graphite electrodes in steel refining involves generating high temperatures through an electric arc, melting the metal at the furnace’s base, and facilitating critical chemical reactions such as decarburization and alloying to produce high-quality steel.

Attrition rate
The rate at which UHP graphite electrodes are consumed in an EAF depends on the steelmaking or other raw materials used, the grades of steel being produced, and the amount of supplemental (chemical) energy used. EAFs typically consume electrodes at a rate of around 2kg per tonne of steel produced, with some specialty steel applications consuming at a slightly higher rate.
