RP Graphite Electrodes For Steel Smelting Dia. 75-200mm (Inch 3″- 8″)
Overview
The Regular Power (RP) Graphite Electrode is made of high-quality petroleum coke and pitch, through calcining, batching, kneading, molding, baking, graphitization, machining, and the Graphite Electrode Nipple is made by three times impregnation and four times baking process.
Features
- Perfect chemical stability
- Low coefficient of thermal expansion, resistance to cracking, brokenand thermal shock
- High mechanical strength
- High machining accuracy and good surface
- Low consumption using rate
Applications
- For Ladle furnacesteel making
● For Electric arc furnace steel making
● For Yellow phosphorus furnace
● Apply to Industrial silicon furnace or melting copper
● Apply to Refine steel in ladle furnaces and in other smelting processes

Packing
All goods will be packed in strong exporting wooden pallets.
Products Transportation and Installation Introductions:
(1)The Electrodes should be kept in a clean, drying place and avoid vibrations and collisions. It should be dried before use.
(2) When installing the joint, please clean the hole with the compressed air, then carefully screw the joint and not damage the thread.
(3)When connecting electrodes, the two electrodes should be cleaned with compressed air when they are 20-30mm apart.
(4)When using a wrench to connect the electrode, it should be completely taut to the specified position so that the gap between the two electrodes is not less than 0.05mm
(5)To avoid the electrode fracture, please avoid the insulation block.
(6)To avoid the electrode fracture, please place the bulk block in the upper part.
