Electric Arc Furnace UHP 20inch Graphite Electrodes
Electric Arc Furnace UHP 20inch Graphite Electrodes
Did you know that there are two ways to make iron? 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 Electrode has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron.
The graphite electrode for arc furnaces and ladle refining furnaces for steel industries/steel plant in steel making.
