Used Carbon Graphite Electrode For EAF LF Corrosion Resistance
Used Graphite Electrode
After the raw materials are broken and processed to a suitable particle size, they are sent to a 1000-1300 calcined for heat treatment to remove water and volatiles in the raw materials, so as to improve their density, mechanical strength, thermal and electrical conductivity.
- Product Details
Graphite chemical sequence is a key link of the artificial graphite electrode, it is in the atmospheric pressure and above temperature, the petroleum coke and asphalt coke carbon atoms from the two-dimensional space of the disorderly layer structure, into three-dimensional ordered arrangement of graphite grains.
The larger the particle size, the faster the discharge speed and the smaller the roughing loss. The primary reason is that the discharge energy changes with the current intensity during the discharge process. However, the surface finish after discharge changes with the change of particles. Graphite electrode is the preferred data in industry.
It is because the graphite electrode has impeccable advantages, the correct selection of graphite electrode specification and selection of suitable graphite electrode pair is the key.
