The main raw materials of carbon electrodes are petroleum coke, anthracite, and metallurgical coke. Sometimes, a tiny amount of graphitized fragments are added and made through batching, molding, roasting, and mechanical processing. It is an excellent carbonaceous conductor material. They are used in medium and small electric arc furnaces and electric furnaces to produce ferroalloys, yellow phosphorus, and corundum as conductive electrodes.
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 графитовый электрод.
Они обладают отличной электропроводностью. Это объясняется тем, что он состоит в основном из ковалентно связанных атомов углерода, покрытых металлическими связями, что благоприятствует потоку свободных электронов и имеет низкое удельное сопротивление.
Приложения:
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:
Submerged arc furnace capacity(KVA)
6300
8000
12500
25000
Electrode Diameter Specification(mm)
780/800
900
960/1020

Главная особенность:
Электропроводность: They possess exceptional electrical conductivity, which promotes efficient electrical energy transmission. This property makes them suitable for applications such as electrolysis.
Механическая прочность: Они обладают значительной механической прочностью, что позволяет им выдерживать механические нагрузки и деформации во время работы. Это качество жизненно важно для приложений, работающих с механическими силами или вибрациями.
Термическая стойкость: Они демонстрируют высокую термическую стабильность, что позволяет им выдерживать высокие температуры без значительного разрушения. Эта особенность особенно важна для процессов, связанных с высокой температурой, таких как электродуговые печи или резистивный нагрев.
Химическая инертность: They are corrosion resistant and chemically nonreactive. So this property makes them applicable in aggressive environments where other materials would degrade.
Преимущества в производстве:
The production of raw materials for it is relatively simple as it eliminates the графитизация 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 графитовый электрод. 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.
