DESCRIPTION
Graphite electrodes are commonly used in steel making, as they are a crucial component for electric arc furnaces. These electrodes are made of high-quality carbon materials such as graphite, which is a product of calcined petroleum coke.
Calcined petroleum coke is a byproduct of the oil refining process. In this process, petroleum coke is heated to high temperatures, resulting in the removal of volatile hydrocarbons and other impurities. The remaining material is calcined at temperatures above 1200°C, which results in the formation of high-quality carbon products, including graphite.
The use of high-quality calcined petroleum coke ensures that the resulting graphite electrodes have excellent electrical conductivity, high mechanical strength, and low electrical resistance. These properties are essential for the efficient operation of electric arc furnaces, which are used extensively in steel making.
