There are two main techniques to make iron, that are the blast furnace technique and the electric arc furnace technique. The graphite electrodes are basically the conductors that are used in the electric arc furnace to melt the iron. With industrial advancements, graphite has become more efficient and can now conduct more power and higher currents. It also has great thermal conductivity, and it is also resistant to heat and impact, which makes it ideal for steel recycling and other melting procedures. But how is the graphite electrode manufactured? Here you would find the production process of the graphite electrode.
The Initial Stage
The process of the manufacturing of graphite electrodes starts with the blending of all raw materials. Subsequent to the grinding of these raw materials, they are then blended with a liquid pitch which is a kind of tar of the resin. The mixture of this pitch with the tar forms a graphite mixture which is then held into molds. The casts are then trembled at high speeds to compress the blend. The electrodes are then turned into a pitch coke.
The Baking Step
As the electrodes are turned into a pitch coke, subsequently, they are baked, making a robust electrode. The texture of the electrode is then enhanced when they enter into an autoclave. In this autoclave, they soak up the liquid pitch. The electrodes are then baked again and solidify their composition.
The Resultant Product
As the electrodes are again baked at 3000 degrees Celsius, the graphite is produced. This manufactured product is completed when the wholesale graphite electrode supplier customizes it with the help of some machining and provides their clients with these consumable materials.
