Below is the brief introduction of my company's electrode products. They are for electric arc furnaces, ladle furnaces and foundries.
1. Diameters range from 75mm to 700mm
2. Lengths range from 1200mm to 2600mm
3. Full range of grades for electrodes: NP, IP, HP, SHP, and UHP
4. 100% Needle Coke is imported from U.S.A (Seadrift Coke), UK (Conocophillips), Japan
5. All pins are UHP quality
