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 primary function is to contain the molten iron and scrap charge, and to facilitate the conversion of molten iron into steel by injecting high-purity oxygen to oxidize impurities such as carbon, silicon, manganese, and phosphorus.
The vessel typically has a carbon steel shell and a refractory lining, often made of magnesia-carbon or dolomite bricks. The specific materials and grades should be confirmed with the manufacturer for the actual model.
Typical nominal capacity ranges from 100 to 300 tonnes, inner volume from 80 to 200 m³, height from 8 to 12 m, and inner diameter at the barrel from 5 to 7 m. These are reference ranges and must be verified for specific installations.
The vessel is tilted using a drive system that provides a tilt torque of 5000 to 15000 kN·m, allowing tilt speeds of 0.1 to 1.0 rpm. Oxygen is injected through a lance at flow rates of 500 to 1500 Nm³/min and pressures of 1.0 to 1.5 MPa. Always confirm these values with the supplier.
