Dia 400mm 400 Uhp Graphite Electrodes
Dia 400mm 400 UHP graphite electrodes are high-density carbon-graphite consumables designed for electric arc furnace steelmaking, where they conduct ultra-high electrical currents to melt scrap metal. These electrodes have a diameter of exactly 400mm and are manufactured to meet international UHP standards, with a bulk density above 1.72 g/cm³ and resistivity below 5.5 μΩ·m, as stated in the source data. The material is high purity carbon graphite, processed to minimize ash content and ensure stable arc performance under continuous high-power operation.
Typical industry specifications for UHP electrodes of this size include a flexural strength range of 12 to 16 MPa and a coefficient of thermal expansion between 1.2 and 1.8 ×10⁻⁶/°C. The electrodes are produced using petroleum coke and pitch pitch as binders, then graphitized at temperatures exceeding 2800°C. Surface finish is machined to ±0.5mm tolerance, and thread specifications follow ISO 1013-1 for coupling with electrode holders. These are not standard electrodes but engineered for large-scale steel plants requiring continuous operation over 12-hour cycles.
Primary buyers include integrated steel mills in Southeast Asia, the Middle East, and Eastern Europe that operate EAFs with capacities above 100 tonnes. These electrodes are shipped in wooden crates with internal foam padding to prevent breakage during transit. The supplier states annual production capacity of 50,000 MT for graphite electrodes and maintains large stock, enabling prompt shipment within 15 to 25 days after order confirmation. Trade terms are typically FOB Qingdao or CIF, with payment by irrevocable letter of credit.

Sourcing Dia 400mm 400 Uhp Graphite Electrodes from Rongxing Group - China Import Guide
Before placing an order, verify the electrode's material composition, resistivity, and bulk density with a certified test report from the supplier. Confirm the thread dimensions match ISO 1013-1 and request a batch-specific certificate of analysis for ash content. Do not accept electrodes without documented compliance to UHP standards, as substandard material can damage furnace components and increase operational downtime.
Lead time is typically 15 to 25 days after order confirmation, depending on stock availability. Trade terms are commonly FOB Qingdao or CIF to destination port. Payment is usually via irrevocable letter of credit. Buyers should confirm whether the supplier handles export documentation, including phytosanitary certificates if required by destination countries. Ensure the packaging is robust, with internal foam padding to prevent breakage during ocean transit.
Quality checks should include visual inspection for cracks or chips, measurement of diameter and length with calibrated tools, and verification of thread integrity. Request a sample batch for a burn test under controlled EAF conditions to assess oxidation rate and arc stability. Ensure all documentation includes batch numbers traceable to the production line. Retain a sample from each shipment for independent lab testing if quality disputes arise.
