Ultra-high power graphite electrodes are a core consumable in modern electric arc furnace steelmaking, specifically designed for the high-current, high-temperature smelting scenarios in steel plants. They can generate temperatures exceeding 3000°C through a high-intensity arc, enabling rapid melting of scrap steel and refining of molten steel. The product is made from 100% imported needle coke, processed through three impregnations and four baking cycles, and high-temperature graphitization, resulting in top-tier performance: bulk density ≥1.69 g/cm³, resistivity ≤5.5 μΩm, thermal expansion coefficient ≤1.5×10⁻⁶/℃, and flexural strength ≥12.0 MPa, with superior joint performance (bulk density ≥1.75 g/cm³, resistivity ≤4.5 μΩm).
Suitable for 145-ton and larger ladle refining furnaces, the refining time is only 11-15 minutes per furnace, with electrode consumption as low as 0.30 kg/ton of steel, saving over 15% energy compared to ordinary electrodes and increasing smelting efficiency by 20%. The product features tightly fitting joints, resistance to extreme temperature differences and electromagnetic vibration, and no risk of detachment or breakage, effectively ensuring continuous production in steel plants, reducing overall operating costs, and serving as a key supporting material for the green upgrade of short-process steelmaking.
