Graphite electrode, mainly uses petroleum coke, needle coke as raw material, coal pitch as binder, is made through calcination, ingredients, kneading, molding, baking, graphitization and machining, which is released electricity in electric arc furnace in the form of arc conductor to heat and melt furnace charge. It has the characteristics of low resistivity, good conductivity, low ash, uniform and compact structure, good oxidation resistance and high mechanical strength.

UHP Graphite Electrodes Benefits

Our product is made of high quality low ash materials, such as petroleum coke, needle coke and coal pitch.

From calcining, burdening, kneading, forming, baking to pressure impregnation, graphitization, we pay attention to every detail to make it boutique.

We know machining is very important, so we precision machined with professional CNC machining to make sure high quality.

Such of the products own characteristics with low resistivity, good electrical conductivity, low ash, compact structure, good antioxidation and high mechanical strength.
