Refractory lining is a heat-resistant protective layer inside non-ferrous metal induction melting furnaces that withstands extreme temperatures and chemical corrosion.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Porosity | 15-25% | |
| Thickness | 150-300 mm | |
| Bulk Density | 2.2-2.8 g/cm³ | |
| Thermal Conductivity | 1.5-3.0 W/m·K | |
| Cold Crushing Strength | 30-60 MPa | |
| Max Service Temperature | 1700°C |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
Industrial furnace using electromagnetic induction to melt non-ferrous metals with precise temperature control.
A refractory-lined vessel used in continuous casting to receive molten metal from a ladle and distribute it evenly to the mold.
A specialized vessel within a molten metal degassing system where dissolved gases are removed from molten metal through controlled processes.
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.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Replacement frequency depends on operating conditions, typically 6-24 months for continuous operation. Factors include metal type, temperature cycles, and slag chemistry.
Visible cracks, increased energy consumption, metal penetration on furnace exterior, abnormal temperature readings, and reduced melting efficiency indicate lining degradation.
