Graphite Electrodes | Tokai Carbon Co., Ltd.
The blast furnace method and the electric arc furnace method. The electric arc furnace method recycles used iron scrap by melting it in an electric arc furnace. It is the graphite electrodes inside the furnace that actually melt the iron. Graphite has high thermal conductivity and is very resistant to heat and impact.
Graphite electrode for electric arc furnace - Rongxing Group
The steel-making electric arc furnace uses graphite electrodes as conductive materials and transfers heat energy to the charge through arc discharge to melt the charge. An ordinary electric arc furnace has three electrodes, each of which consists of 3 to 4 electrodes connected together with a tapered joint.
Graphite Electrodes. Graphite electrodes are used mainly in the production/recycling of steel, where steel scrap is melted in a large furnace by the heat from an electric arc, hence ‘electric arc furnaces’. Approximately 1/3 of global steel is produced in this way, making it the largest recycling process in the world.
Electric arc furnace - Wikipedia
An electric arc furnace ( EAF) is a furnace that heats material by means of an electric arc . Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking. Arc furnaces used in research laboratories and ...
Application of Graphite Electrode in Steelmaking Electric Arc ...
Electric arc furnace steelmaking is heated by an electric arc, and its temperature can be as high as 2 000 ℃ or more. This exceeds the maximum temperature that other steelmaking furnaces can reach when burning and heating with general fuel. The thermal efficiency is higher than that of the open hearth and converter steelmaking methods.
