Graphite electrodes are mainly used in eAF steelmaking.Electric furnace as the core steelmaking technology has obvious advantages in production efficiency, environmental protection, infrastructure investment cost, process flexibility and other aspects, electric furnace steelmaking is the use of electrode into the furnace current.A strong current will pass through the gas at the bottom of the electrode to produce an arc discharge, while releasing a large amount of heat for smelting.
Graphite electrode has high quality characteristics unmatched by other components:
1.Graphite has good thermal stability, at 3550℃ when sublimation, ordinary metal has melted at this high temperature;
2.The resistance is very low, only a few ohms, smelting energy consumption is small;
3.Light weight, less than 1/4 of the density of copper, easy to transport and use, good safety, easy to clamp when melting on the furnace;
4.Raw materials for easy asphalt, petroleum coke, needle coke, etc.;
5.Good processability, 3-5 times faster than ordinary metal.
