How Graphite Electrodes Are Manufactured | M. Brashem,

Graphite ElectrodesThe Beginning of The Manufacturing ProcessThe Baking ProcessThe Completed ProductIf you are familiar with arc welding, you know that a current is passed from an electrode (rod) to the metal parts you want to weld. A welding rod (which is made from a material like steel or aluminum) may or may not contain a flux core. Friction from the electric current then heats the rod, melting it into the metal joint to form a strong weld. In an arc furnace, however, the welding rods are much larger but serve the same basic principle. Large electrodes (made from carbon compounds) come i
