Product Introduction

Small diameter graphite electrode (Diameter: 75mm-225mm) main used for smelting calcium carbide, carborundum, white corundum, rare metals smelting, as refractory in Ferrosilicon plant, etc..

Graphite electrode is a kind of high temperature resistant graphite conductive material made of petroleum coke and needle coke as aggregate and coal asphalt as binder through raw material calcination, crushing and grinding, batching, kneading, extruding, baking, impregnation, graphitization and mechanical processing. It is called artificial graphite electrode.
