Renewable Design for Uhp 250 Mm Graphite Electrodes - HP Graphite electrode – Yidong Detail:

Description
This product is mainly applied for higher power elecric arc furnace as a conductive material,the high power graphite electrode was produced with high quality raw material and the quality is controlled strictly during production process.Our products won the trust of the users by good quality,reasonable price and attentive service.
We have HP graphite electrodes diameter 100-700mm.

Feature
1.High mechanical strength, low electrical resistance.
2. High-purity, high-density, strong chemical stability.
3.High machining accuracy, good surface finishing.
4.High resistance to oxidation and thermal shock.
5.Anti-oxidation treatment for longevity.
6. Resistant to cracking & spalling.

Quality requirements
1.There should be less than two defects or holes on the electrode surface.
2. There should be no transverse crack on the electrode surface. For the longitudinal crack, the length should be less than 5% of the electrode circumference and the width should be 0.3 to 1.0 mm.
3. The width of black area on electrode surface should be less than 1/10 of the electrode circumference and the length should be less than 1/3 of the electrode.

Specification
The physical and chemical indexes of high-power graphite electrodes and nipples refer to YB/T 4089-2015
