Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It is used as a consumable electrode in submerged arc furnaces to produce ferroalloys like ferrosilicon, ferromanganese, and ferronickel. It conducts electricity and generates heat for smelting.
They are made from calcined anthracite, petroleum coke, and coal tar pitch binders. These materials are processed to achieve the required electrical and thermal properties.
Key specifications include diameter (400–800 mm), length (1500–2500 mm), ash content (≤5%), volatile matter (12–16%), compressive strength (≥25 MPa), bulk density (1.40–1.55 g/cm³), and electrical resistivity (40–60 μΩ·m). Always confirm with the supplier.
Handle carefully to avoid damage. Monitor for signs of oxidation, cracking, or dimensional changes. Ensure operating temperatures do not exceed the maximum (1200–1400 °C) to prevent premature failure.
