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.
According to the directory, the diameter typically ranges from 1200 to 3000 mm. This range determines the sheet width and production capacity. However, the exact value must be confirmed for the specific model and application with the legal manufacturer or supplier.
The shell material is often specified as cast iron grades such as HT250–HT300, which offer high thermal conductivity. Additionally, the cylinder may be constructed from stainless steel or carbon steel, depending on the application. Always verify the material grade with the manufacturer.
TIR is a measure of the cylinder's rotational accuracy. The directory lists a maximum TIR of 0.05 mm, which is critical for uniform drying and sheet quality. Excessive runout can lead to uneven drying and vibration. This value should be verified against the manufacturer's specifications.
The operating pressure, typically 1.0–1.6 MPa, affects the heat transfer and the sealing of the cylinder. The pressure must be maintained within the specified range to ensure safe and efficient operation. Always confirm the pressure rating with the supplier.
