Function: To clamp electrodes and transmit current. It is a crucial component affecting the electrical parameters of the secondary circuit in an electric arc furnace (EAF) and plays a vital role in ensuring safe operation and production efficiency.
Material: Made from forged pure copper or chromium-zirconium copper (CuCrZr) through mechanical processing, offering high conductivity, oxidation resistance, and mechanical strength. The electrode clamp adopts a water-cooled structure, reducing energy loss and extending its service life.
Material Properties:
► Excellent Conductivity: Copper provides superior conductivity, ensuring efficient current transfer from the clamp to the electrode. This is essential for stable EAF and steelmaking operations while improving energy efficiency.
► High Thermal Conductivity: During steelmaking, electrodes generate significant heat. The copper clamp’s high thermal conductivity helps dissipate heat quickly, lowering its own temperature and prolonging service life. It also maintains a stable electrode temperature, ensuring process stability.
► Optimal Hardness & Strength: While copper is relatively soft, the clamp must possess sufficient hardness and strength to withstand electrode pressure and clamping force without deformation or damage. Proper material selection (e.g., copper alloys) and heat treatment enhance these properties.
Structure & Features:
► Electrode Holder: Machined from forged pure copper or CuCrZr, it delivers ultra-high conductivity for stable current transmission and minimized energy loss. Its oxidation resistance ensures durability in high-temperature, harsh environments, while robust mechanical strength guarantees reliable electrode fixation under extreme EAF conditions.
► Electrode Support: Features a water-cooled design that significantly reduces energy loss. Circulating coolant dissipates heat, preventing overheating-induced performance degradation or failure, thereby extending service life. This cooling system maintains optimal operating temperatures, ensuring consistent performance and enhancing EAF safety and productivity.
► Electrode Clamp: Fabricated from forged pure copper or CuCrZr, it combines high conductivity, oxidation resistance, and mechanical strength to efficiently transfer current from the power source to the electrode, stabilizing EAF and steelmaking operations. Its superior thermal conductivity rapidly disperses electrode-generated heat, lowering clamp temperature and prolonging lifespan. Precision-engineered copper materials provide balanced hardness/strength to endure clamping forces without deformation. The water-cooled structure further reduces energy consumption and improves durability.
