Graphite electrodes uhp abbreviation and uhp electrodes electrical resistance

Graphite electrodes uhp abbreviation is ultra high power graphite electrodes, It is a conductive material used in the smelting of electric arc furnace.

Graphite electrodes uhp meanning

The abbreviation of UHP is ultra high power, Graphite electrode can be divided into 3 types according to the power: RP, HP and UHP. It is a kind of consumable material of arc furnace, which smelts scrap steel by generating an arc between electrode and scrap steel by electric current.

Graphite electrodes uhp structure drawing, It is composed of body and nipple.
The diameter of UHP graphite electrode is 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm, 650mm and 700mm.

Graphite electrodes uhp performance

• High current carrying capacity
• High resistance to thermal shock
• Outstanding flexural strength
• High temperature resistance to oxidation
• Low modulus of elasticity
• Low coefficient of thermal expansion

UHP electrodes electrical resistance

uhp electrodes electrical resistance is 4.2~5.8 μΩ·m.
UHP graphite electrode used in high power electric arc furnace steelmaking, it has low resistivity, big volume density, high mechanical strength, small linear expansion coefficient and the characteristics of oxidation resistance optimal, can shorten the steelmaking time, increase production efficiency, lower power consumption and reduce the rate of graphite electrode consumption, its physical and chemical index is better than that of the RP, HP graphite electrode.
