Graphite Electrodes
Graphite electrodes           including RP Graphite Electrodes          , RPI, HP, SHP and UHP Graphite Electrodes           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 Solutions           are:
(Dia. 75-Dia. 700mm)
Our Ladle furnace Graphite Electrodes           has the following feature:
1. Lower electric resistivity, good electric and heat conductivity;
2. High mechanical strength under high temperature;
3. High resistance to thermal shock and mechanical vibration;
4. Lower ash content;
5. According to the customer's feedback information, our electrodes used in EAF/LF with the pretty lower consumption per ton steel.
We main supply electric arc furnace graphite electrodes          , direct current furnaces electrodes          .
look forward to working with you for a long time!
