250mm UHP Graphite Electrode
The 250mm UHP (Ultra-High Power) Graphite Electrode stands at the pinnacle of graphite electrode technology, designed for state-of-the-art EAFs that demand maximum power input and operational excellence. It is the preferred choice for premium steelmaking facilities aiming to achieve unprecedented efficiency, productivity, and sustainability.
Key Features: UHP electrodes boast the lowest electrical resistivity in the graphite electrode family (often <50 μΩ·m), allowing them to operate at current densities exceeding 35 A/cm²-far higher than HP or RP grades. Their microstructure is ultra-dense, with impurity levels (sulfur <0.03%, vanadium + titanium <0.02%) meticulously controlled to minimize energy loss and maximize thermal conductivity. Mechanically, they feature exceptional flexural strength (>100 MPa) and thermal shock resistance, even at extreme temperatures (up to 3,000°C).
Applications & Roles: UHP electrodes are indispensable in large EAFs (1,500 kVA and above) used for producing high-grade steels, including stainless steel, tool steel, and specialty alloys. They enable rapid melting of large scrap charges, precise temperature control, and reduced electrode consumption, directly contributing to lower carbon footprints in steel production.
Advantages: By minimizing resistive losses, UHP electrodes can reduce energy consumption by 10–15% compared to HP grades, translating to significant cost savings and environmental benefits. Their extended lifespan (up to 40% longer than HP electrodes) further enhances operational efficiency, reducing downtime for electrode changes. For steelmakers, UHP electrodes are a strategic investment in cutting-edge technology, enabling them to meet the growing demand for high-quality, sustainably produced steel.
