Overview：
Power (RP) Graphite Electrode is made of high-quality petroleum coke and pitch, through calcination, batching, kneading, molding, baking, graphitization, machining, and the Graphite Electrode Nipple is made by three times impregnation and four times baking process.
Graphite electrode nipples are essential components used in electric arc furnace (EAF) steelmaking, as as in the production of ferroalloys and other types of alloys. These nipples serve as connectors for graphite electrodes, providing a crucial link between the power source and the electric arc furnace. The quality and performance of graphite electrode nipples directly impact the efficiency and stability of the EAF steelmaking process. As a result, manufacturers and steel producers place significant emphasis on selecting high-quality graphite electrode nipples to ensure optimal performance and productivity in their steel production operations.
Features：
- Great chemical stability;
- Low coefficient of thermal expansion, resistance to cracking, spalling and thermal shock;
- Higher mechanical strength;
- Higher machining accuracy and good surface finish;
- Long operation life.
Applications：
Regular Power (RP) Graphite Electrodes are suitable for all kinds of AC/DC Regular Power Electric Arc Furnaces, Resistance Furnaces, Submerged Electric Furnaces for smelting all kinds of alloy steel, metal, non-metal, etc.
