Regular Power Graphite Electrodes
- Commodity name： Regular Power Graphite Electrodes
- Description
-
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.
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.
