Dia 300mm Uhp 300 Graphite Electrodes
This 300mm diameter UHP 300 graphite electrode is manufactured from carbon graphite with a minimum 99.5% carbon content, designed for electric arc furnace steelmaking where high thermal conductivity and low electrical resistance are critical. The standard length is 1800mm, consistent with industry norms for electrodes of this diameter, and it is rated for ultra-high power operations in scrap-based steel production. The electrode maintains arc stability under prolonged high-current loads, reducing energy loss and electrode consumption.
The material is processed from petroleum coke with controlled grain structure to ensure uniform density and low porosity. Typical resistivity for UHP 300 grade is between 5.5 and 6.5 microohm-meters, and the coefficient of thermal expansion is under 1.5 x 10^-6 /K. These electrodes undergo vibration compaction and graphitization at temperatures exceeding 2800°C to achieve structural integrity. Surface finish is smooth with minimal machining marks, and end face flatness meets standard industrial tolerances.
These electrodes are purchased by mid-to-large steel producers in Southeast Asia, the Middle East, and Eastern Europe for secondary steelmaking. Buyers typically order in bulk shipments of 10 to 50 metric tons per container, with packaging in wooden crates or steel pallets to prevent breakage. Stock is maintained for immediate dispatch, and lead times are generally 15 to 25 days after order confirmation. Incoterms are typically FOB Qingdao or CNF, with payment by letter of credit or T/T.

Sourcing Dia 300mm Uhp 300 Graphite Electrodes from Rongxing Group - China Import Guide
Before ordering, verify the electrode’s carbon content, resistivity, and density against the supplier’s certificate of analysis. Confirm that the diameter and length fall within standard tolerances (±1.5 mm and ±5 mm respectively). Check for surface cracks or delamination under inspection lighting. Do not rely on marketing claims - demand test data for each batch.
Confirm the Incoterms offered - FOB Qingdao is common - and ensure the supplier handles export documentation including commercial invoice, packing list, and bill of lading. Lead time is typically 15 to 25 days after order confirmation. Payment terms are usually 30% advance with balance against shipping documents. Ask for proof of export experience with your destination country.
Perform a visual and dimensional inspection upon arrival. Use a caliper to verify diameter and length, and check for surface defects. Request a sample from each batch for resistivity testing if volume is large. Ensure packaging is intact and moisture-proof. Retain a sample for future reference if quality disputes arise. Document all findings and communicate discrepancies immediately to the supplier.
