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 nozzle is available in alumina-zirconia-silica (AZS) refractory or graphite-enhanced ceramic composite. Material selection depends on the application and required properties.
The maximum operating temperature is 1700°C, as per ISO 8361. However, actual limits may vary with the specific material and design; confirm with the manufacturer.
Erosion resistance is indicated by an index of 85–95 cm³ volume loss under standardized slag testing (ASTM C704). Lower volume loss indicates better resistance.
Relevant standards include ISO 3302-1 for bore tolerance, ISO 8361 for temperature, ISO 17562 for thermal expansion and shock, ISO 5017 for porosity and density, ISO 10059-1 for strength, ASTM C704 for erosion, and ISO 12677 for alumina content. These are references for verification, not certifications.
