Application:
Graphite electrodes are used mainly in ladle furnaces,electric-arc furnace steelmaking,Yellow phosphorus furnace , Industrial silicon furnace or melting copper. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment.High Quality Needle Coke in HP&UHP graphite electrode,ensure the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
Properties:
1. Good electrical conductivity.
2. Strong thermal shock resistance.
3. High mechanical strength.
Variety:
1. RP (Regular Power)
2. HP (High Power)
3. UHP (Ultra High Power)
4. RPI (Regular Power Impregnated)
(Notice: All of Graphite Electrodes is equipped to tapered nipple
Quality Assurance & Control
· National Certified Laboratory
· Key testing instruments, including: specific resistor, bulk density meter, elasticmodulus meter, bending strength inspector, ash analysis meter, CTE analysis meter, etc.
· On-time instrument calibration
· On-site properties testing, including:
L-CTE,C-CTE
Specific resistance, bulk density,
Bending strength, ash content, elastic modulus
