Ray Group Limited Co., Ltd. manufactures carbon electrodes in China, offering diameters from 500 mm to 1400 mm. The company provides two grades, normal and high, with normal grade resistivity up to 45 µΩ·m and high grade down to 38 µΩ·m. Bulk density ranges from 1.55 g/cm³ (normal) to 1.58 g/cm³ (high), and ash content is limited to 2.5 % (normal) or 2.0 % (high).
Typical carbon electrodes for electric arc furnace use a bending strength of 3.5 - 4.0 MPa and compressive strength of 20 MPa, matching industry standards for furnace electrodes. The coefficient of thermal expansion is usually between 3.0 ×10⁻⁶/°C and 3.2 ×10⁻⁶/°C for the temperature range 100‑600 °C, which aligns with standard furnace design tolerances. Current carrying capacity varies with diameter; for example, a 800 mm normal‑grade electrode can carry 33 kA at a density of 6.6 A/cm², while a high‑grade of the same size carries 38 kA at 7.6 A/cm². These values are typical for electrodes used in steel‑making processes.
Buyers such as steel producers and large‑scale foundries purchase these electrodes for electric arc furnace operations, valuing the higher current density of the high grade. The supplier lists the product in bulk packaging, but exact MOQ and price must be confirmed directly. Importers should request trade terms, incoterms and payment conditions before finalising the contract. Verification of certification and testing reports is recommended during the sourcing stage.

Before placing an order, importers should obtain the supplier’s latest test certificates for resistivity, bulk density and mechanical strength, and verify that the electrodes meet the specifications required for their furnace design. Request a material safety data sheet and, if needed, a third‑party inspection report to confirm compliance with industry standards.
Logistics for carbon electrodes typically involve bulk freight in steel containers, with the supplier likely to quote FOB Qingdao. Confirm the preferred Incoterm, expected lead time and payment terms with the supplier, as these details are not published in the listing. Ensure that packing dimensions and weight calculations account for the 1.55‑1.58 g/cm³ bulk density range.
During quality assurance, arrange for pre‑shipment sampling and visual inspection of electrode dimensions and surface condition. Verify that the ash content and CTE values fall within the stated limits, and consider a post‑delivery performance test in the furnace to confirm current carrying capacity. Documentation such as a certificate of conformity should be secured before final acceptance.
