Graphite Rod Electrode

Graphite rod electrodes are usually in cylindrical form and widely used in metal smelting and other fields. They are an indispensable part of modern industrial production. Our electrodes have excellent conductivity, and can withstand high temperatures. So these materials remain stable even under high temperature conditions and are not easy to melt. Besides, their chemical stability is a key attribute that gives them excellent corrosion resistance, and that is suitable for a wide range of environments.

Main Features:

Excellent Conductivity, High Temperature Resistance, Chemical Stability Electrode rods are made of high-purity graphite. They have high strength and low resistance, which enables them a longer service life. They have amazing thermal shock resistance and they can sustain rapid temperature changes. At the same time, these electrode rods can be precisely processed to manufacture components of various shapes and volumes. And they maintain the consistency of electrical and thermal conductivity of the same batch of materials, which can meet the needs of different industries.

These graphite rod electrodes have strong oxidation resistance, acid and alkali corrosion resistance, and wear resistance. It has become the preferred material for application in different chemical environments such as electrolysis and smelting.

Graphite Rod Electrode Uses

Electric arc furnace steelmaking:

Graphite rod electrode is used to generate high-temperature arc to melt scrap steel or ferroalloys. It also plays the dual role of conductivity and high temperature resistance to ensure the smooth progress of the electric furnace steelmaking process.

Resistor furnace heating:

In the resistance furnace, it can be used as a heating element to provide a stable heat source.

Electrolytic Cells:

They are used as anodes or cathodes in the electrolytic process, especially in the production of metals such as aluminum. It can be processed into graphite rotors and used for ventilation during the stirring of aluminum liquid.

Special Welding:

Graphite electrodes are also used in special welding techniques such as resistance welding and arc welding.

Nonferrous Metal Smelting:

As conductive materials, Nonferrous Metal convert electrical energy into heat energy for melting and nonferrous metals refining.

Differences between graphite rod electrodes and other material electrodes:

Structural differences:

Compared to glassy carbon, graphite has a highly ordered crystal structure composed of hexagonally arranged carbon atom layers, while glassy carbon is an amorphous, non-graphitizable form of carbon.

Physical Attributes:

Graphite is outstanding in thermal and electrical conductivity.

If glassy carbon is reduced thermal conductivity, then there will be higher electrical resistance.

Mechanical properties:

Graphite’s edge planes have a slippery, flexible structure that can be peeled along the basal plane, while glassy carbon is dense and hard, with no permeability to gases or liquids.

Application differences:

Graphite rod electrodes are widely used as electrodes in electric arc furnaces, lithium-ion batteries, and other high-temperature applications, while glassy carbon, due to its excellent properties, is the preferred choice for precision parts with high tolerance and detail requirements.
