Hebei Fengchao Import and Export Co., Ltd. is one of the most reliable manufacturers and suppliers of graphite electrode 400×2400mm in China. With a professional production team, we are able to meet the needs of the majority of our customers. If you're going to wholesale bulk graphite electrode 400×2400mm made in China, welcome to get pricelist from our factory.
Our HP graphite electrode 400×2400mm is an elongated single piece of medium diameter. The extended single-body design reduces the number of nipples in the electrode string, effectively cutting nipple consumption and the probability of failures at nipple joints. It features robust mechanical strength and can withstand severe mechanical shocks generated during furnace tilting for tapping. Suitable for 50-70 ton AC electric arc furnaces, it helps medium-sized steel mills maintain a stable continuous melting rhythm and lower the overall operating cost of steelmaking lines.
The HP graphite electrode 400×2400mm is manufactured from qualified needle coke raw materials with an elongated fixed-length design. The increased length of each electrode reduces the number of nipples in the electrode column, lowering unplanned shutdowns caused by nipple fracture during smelting. The material boasts excellent fatigue resistance to endure repeated mechanical vibration from frequent furnace tilting and tapping, while retaining stable electrical conductivity under fluctuating thermal loads. This specification is mainly applied to 50-70 ton AC EAFs of medium-sized iron and steel enterprises. It is ideal for production lines aiming to boost effective melting time by cutting downtime for electrode replacement, helping medium-sized steelmaking workshops steadily unlock production capacity.
Our HP 400×2400mm graphite electrode adopts custom deformation-resistant raw materials and dedicated production processes for long blanks. Equipped with professional long-size processing equipment and a full-process quality inspection system, it delivers minimal deformation and strong fatigue resistance, perfectly matching the working conditions of frequent furnace tilting and continuous smelting in medium-sized EAFs.

FAQ
Q: The HP400×2400mm electrode body is relatively long. What precautions should be taken for on-site hoisting and handling?
A: Due to its elongated body, single-point lifting may cause temporary deflection. Two-point lifting is recommended. Lifting from only one end is prohibited, to avoid invisible internal microcracks that could lead to fracture after furnace charging.
Q: Is it necessary to verify the electrode lifting travel of the electric furnace before selecting the elongated HP400×2400mm electrode?
A: Yes. The single-piece length of this model exceeds conventional 1800 1900mm electrodes. The maximum downward travel of the water-cooled clamp shall be verified. Insufficient travel will restrict the descending range of the electrode and indirectly shorten the usable length of each electrode.
Q: Will repeated vibration from frequent furnace tilting and tapping cause seizure of nipple threads on HP400×2400mm electrodes?
A: Cyclic mechanical impact from furnace tilting and tapping will gradually affect thread engagement. It is recommended to recheck nipple tightening torque after several heats. If any sign of loosening is detected, the electrode cannot remain in service.
Q: After reducing nipple quantity with elongated electrodes, how to estimate actual service life and replacement cycle for 50 70 ton EAFs?
A: Although nipple failures are reduced, side oxidation remains the primary consumption factor. The replacement cycle cannot be simply extended proportionally to the increased length. It is advised to gradually adjust the electrode replacement interval based on on-site actual smelting records.
Q: What standard is adopted for finished straightness acceptance of this 2400mm long electrode?
A: The full-length straightness is strictly controlled in accordance with metallurgical industry specifications. Every finished electrode undergoes straightness inspection in a constant-temperature calibration zone. Products with warped long bodies are rejected before shipment. Corresponding test records can be provided upon customer request.
Q: Are there any constraints for loading this 2400mm elongated electrode into export shipping containers?
A: The 2400mm specification fits standard 40ft containers, yet stacking arrangements require dedicated planning. Special cushion blocks for elongated electrodes are used during shipment to prevent sliding, collision and damage during ocean transportation.
