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.
The typical scrap charge per heat is 50–120 tonnes, but this varies by furnace design and application. Always confirm the rated capacity with the manufacturer for a specific model.
The transformer rating typically ranges from 60 to 150 MVA, which determines the melting rate. The specific rating depends on the furnace size and production requirements. Refer to IEC 60076 for transformer standards, but verify the actual rating with the supplier.
The tapping temperature is typically 1600–1650°C, which is necessary for proper ladle metallurgy. The exact temperature may vary based on steel grade and downstream processes. Confirm with the manufacturer.
The operating pressure is typically 1.0–1.6 MPa is a relevant standard for valve testing. However, standards are reference points, not proof of compliance. Always verify the actual pressure requirements and standards with the manufacturer.
