Low Ash HP Grade Graphite Electrode Block For Smelting Steel

Country/Region	china
City & Province	zhengzhou henan
Categories	Graphite Electrodes

Product Details

China graphite electrode blocks price per kg made by big machine
equipment
 
Graphite Electrode is the best conductive material for electric arc
furnace and smelting furnace. High quality needle coke in
HP&UHP graphite electrode ensure the electrode application is
perfect. It is presently the only available product that has the
high levels of electrical conductivity and the capability of
sustaining the extremely high levels of heat generated in the
demanding environment.
