Import 550 Uhp Graphite Electrode — Buy in wholesale FOB from Supplier in China

The 550 UHP graphite electrode from Hebei Ben Hong New Material Technology Co., Ltd is an ultra-high-power grade consumable with a 550 mm nominal diameter, engineered for electric arc furnace steelmaking and ferroalloy smelting operations. Its carbon matrix is formulated from needle coke and petroleum coke, bonded with coal tar pitch, then processed through calcination, kneading, moulding, baking, graphitisation, and precision machining. The UHP classification denotes suitability for furnace transformers operating at higher current densities than HP or RP grades, enabling faster melt rates and reduced electrode consumption per tonne of steel. Hebei Ben Hong supplies this electrode from Shijiazhuang, Hebei Province, China's principal graphite electrode manufacturing region.

Needle coke content governs thermal expansion coefficient and mechanical strength at temperature; premium UHP electrodes typically contain 30-40 percent or more needle coke in the filler blend. The coal tar pitch binder carbonises during baking to form a cohesive carbon bond between filler particles. After graphitisation at temperatures exceeding 2,400 degrees Celsius, the material achieves the low electrical resistivity and high thermal conductivity required for arc stability. Nipple threads are precision-machined to ISO 9001:2001 or proprietary standards to ensure joint integrity under torsional and thermal loads. The supplier states low ash, uniform compact structure, and good oxidation resistance as product characteristics, though specific test values are not provided.

Typical applications include EAF-based steel mini-mills, ladle furnaces, and submerged arc furnaces for silicon metal or ferrochrome production. The 550 mm diameter suits large furnaces with bore diameters of 600 mm or greater. Buyers should confirm with Hebei Ben Hong whether the electrode is supplied with pre-attached nipples or as separate pieces, and whether packaging uses steel strapping or wooden cradles for ocean freight. Operating current density, specific consumption rates, and permitted flexural strength values are not stated in the source and should be requested as part of technical qualification.

Hebei Ben Hong New Material Technology Co., Ltd is registered at Room B2506, Huahai Global Plaza, Xinhua District, Shijiazhuang, Hebei Province, 050000, China. The company address places it in Shijiazhuang's central business district rather than at a production site, suggesting headquarters or trading office functions with manufacturing potentially located elsewhere in Hebei. The supplier holds harbor trust tier classification. Response rate and average response time data are not available. The listing does not state year of establishment, production capacity, number of graphitisation furnaces, or export licence details.

Hebei Province accounts for a significant share of global graphite electrode output, with major production clusters in Handan, Chengde, and Tangshan. Buyers should ask Hebei Ben Hong to clarify whether they operate their own baking and graphitisation facilities or function as a trading entity. No quality management certifications, environmental compliance statements, or client references appear in the source profile. Request factory inspection reports, ISO certificates, and third-party test data before committing to volume orders.
