If you're going to wholesale bulk uhp graphite electrode 500×2000mm made in China, welcome to get pricelist from our factory.
Ultra-high power graphite electrode, diameter 500 mm, length 2000 mm. It adopts premium needle coke as the main raw material and coal tar pitch as binder. Manufactured through kneading, extrusion forming, multiple calcinations, impregnation, high-temperature graphitization and precision machining. Equipped with dedicated graphite nipples, it serves as the core conductive consumable for electric arc furnace steelmaking.
This 500×2000mm ultra-high-power graphite electrode features a robust and solid matrix structure, suitable for load-bearing working conditions of heavy-duty electric arc furnaces. It can effectively suppress spiral erosion on electrode sidewalls under intense arc radiation and slow down sidewall consumption during prolonged continuous smelting. As a large-diameter grade, it helps stabilize the reaction environment of the molten bath and ensures the smooth operation of large-capacity EAF steelmaking lines.
This 500×2000mm ultra-high-power graphite electrode adopts a balanced particle ratio and exhibits excellent spalling resistance under violent molten steel splashing. With high overall rigidity, it reduces the swing amplitude of long electrode columns when the furnace undergoes periodic mechanical shocks. In addition to steelmaking in large-capacity electric arc furnaces, it is also applicable to submerged arc furnaces for ferrosilicon and manganese alloy smelting. Ideal for large-scale metallurgical enterprises, it cuts electrode replacement frequency and reduces hot shutdowns during continuous production.
This large-size 500×2000mm UHP graphite electrode is made of compounded premium petroleum-based needle coke and modified coal tar pitch with a high softening point. Manufactured on production lines equipped with large-tonnage rotary chamber extruders and ring roasting furnaces, it undergoes formula-simulated batching, staged gradient roasting and high-temperature graphitization. A dedicated R&D team optimizes heating curves to control residual stress inside large-volume carbon blanks. Special process monitoring stations are set up in the plant, and practical feedback from the engineering departments of downstream smelters is collected to continuously upgrade manufacturing processes. The company holds ISO9001 quality certification and ISO50001 energy management system certification. Every batch of large-diameter products undergoes dimensional verification and stress-related performance testing to guarantee stable operation under working conditions of heavy-duty electric arc furnaces and submerged arc furnaces.

FAQ
Q: What special risks exist during the initial heating phase after column connection of this φ500 large-diameter electrode?
A: Thanks to its large cross-sectional area, there is a notable temperature difference between the interior and exterior in the early heating stage. Rapid power rise must be avoided; otherwise, thermal cracks are likely to form inside the electrode body.
Q: Is it mandatory to select nipples of the same grade and specification when purchasing 500×2000mm UHP electrodes?
A: The use of 500-grade nipples is not compulsory. However, if reduced-size nipples are adopted, the maximum allowable operating current of the entire electrode assembly will be subject to stricter limits.
Q: Under working conditions of ferrosilicon submerged arc furnaces, which factors shorten the service life of this large-size electrode?
A: Violent convection in the molten bath and erosion by strongly basic slag are the main triggers. Reasonable regulation of slag composition can effectively slow the erosion rate of graphite materials.
Q: Can smelters cut the original 2000mm-long electrodes to shorter lengths on-site?
A: On-site self-cutting is not recommended. Arbitrary cutting will disrupt the original stress state of the blank, and the precision of subsequent thread machining cannot be guaranteed.
Q: Can a pre-shipment dimensional re-inspection be arranged for this batch of large-size electrodes before delivery?
A: Yes. Upon customer request, pre-shipment dimensional rechecks can be performed, and corresponding re-inspection records will be provided together with shipping documents.
Q: What suggestions are there for warehouse foundation layout when planning storage areas for such heavy electrodes?
A: The warehouse floor must possess sufficient compressive strength. Uneven foundation settlement should be strictly prevented to avoid hidden deformation risks for heavy long electrodes during storage.
