What is Carbon Electrode?

Carbon conductive electrode, also known as carbon electrode, is made from high quality petroleum coke, pitch coke, etc. as the main raw materials. It can be processed into finished products after roasting. Because it’s not graphitized, their resistivity is higher than Graphitelektrode.

They have excellent electrical conductivity. This is because it is mainly composed of covalently bonded carbon atoms covered with metallic bonds, which is conducive to the flow of free electrons and has low resistivity.

Applications:

Carbon electrodes are mainly used for submerged arc furnaces. The smelting varieties include industrial silicon, yellow phosphorus, ferroalloys, calcium carbide and other metals or non-metals.

In the industrial silicon smelting process, electric current passes through the conductor electrode and the furnace charge, converting electrical energy into thermal energy through electrolysisfor high-temperature smelting.

Generally, the ratio of the capacity of the submerged arc furnace to the diameter of the carbon electrode is as follows:

Main Feature:

Electrical Conductivity: They possess exceptional electrical conductivity, which promotes efficient electrical energy transmission. This property makes them suitable for applications such as electrolysis.

Mechanical Strength: They have significant mechanical strength, enabling them to endure mechanical stresses and strains during operations. This quality is vital for applications that deal with mechanical forces or vibrations.

Thermal Robustness: They demonstrate high thermal stability, which allows them to endure high temperatures without significant degradation. This feature is particularly important for processes that involve high heat, like electric arc furnaces or resistance heating.

Chemical Inertness: They are corrosion resistant and chemically nonreactive. So this property makes them applicable in aggressive environments where other materials would degrade.

Advantages in Manufacturing:

The production of raw materials for it is relatively simple as it eliminates the Graphitierung process. This results in a lower price than graphite electrodes, as graphitization is energy-intensive.

It can be fabricated in submerged arc furnaces with larger diameters, retaining the same capacity as Graphitelektrode. By producing carbon electrode rod with diameters ranging from Φ600 to Φ1400mm, the arc belt in the furnace broadens, ensuring a stable arc. This guarantees better thermal melting efficiency, increased product output, and lower power consumption.

It serving as conductive electrodes in submerged arc furnaces, offer substantial advantages in cost reduction. They aid in energy conservation, emission reduction, and enhancing smelting efficiency and safety.

As a carbon electrode manufacturer, JINSUN use high-quality raw materials to produce products to help your submerged arc furnace production.
