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 nominal capacity typically ranges from 30 to 120 tonnes, depending on the specific application and design. Always confirm the exact capacity with the manufacturer for your intended use.
The ladle is constructed from refractory-lined steel. The refractory lining provides thermal insulation and protection against high temperatures and chemical corrosion. The specific refractory material and thickness may vary; typical lining thickness is 150–250 mm.
The ladle is placed inside a vacuum chamber, and the pressure is reduced to 0.5–1.0 mbar. This low pressure causes dissolved gases like hydrogen and nitrogen to escape from the molten metal. Inert gas purging may also be used to enhance impurity removal.
Signs include excessive refractory wear, reduced ladle life (typically 50–80 heats), or structural deformation. Regular inspection of the refractory lining and shell thickness is essential. If the lining thickness falls below safe limits or cracks appear, relining or repair is necessary.
