Graphite electrodes including RP,RPI,HP, SHP and UHP are widely used in Electric Arc Furnace and Ladle furnace for making alloy steel or other metals and nonferrous metal.
Our main exporting size of Graphite Electrodes are:
(Dia. 75-Dia. 700mm)
Our graphite electrodes has the following feature:
- Lower electric resistivity, good electric and heat conductivity;
- High mechanical strength under high temperature;
- High resistance to thermal shock and mechanical vibration;
- Lower ash content;
- According to the customer's feedback information, our electrodes used in EAF/LF with the pretty lower consumption per ton steel.
