This page explains how Refractory Crucible is classified within Basic Metal Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A high-temperature resistant container used to hold and melt metals or other materials within an induction melting furnace.
Technical details and manufacturing context for Refractory Crucible
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Capacity | 1–500 kg | Select based on melt size |
| Max Operating Temperature | 1600–1800 °C | Above this, structural integrity degrades |
| Thermal Shock Resistance | ≥10 cycles | Number of quench cycles without crackingISO 28764 |
| Bulk Density | 2.5–3.2 g/cm³ | Higher density improves erosion resistanceISO 5017 |
| Apparent Porosity | 15–25 % | Lower porosity reduces slag penetrationISO 5017 |
| Cold Crushing Strength | 30–80 MPa | Minimum for handling and serviceISO 10059-1 |
| Thermal Conductivity | 1.5–3.0 W/(m·K) | Affects heating efficiencyISO 8894-1 |
| Coefficient of Thermal Expansion | 4–8 ×10⁻⁶/K | Match with furnace lining to avoid stressISO 17562 |
| Refractoriness Under Load | 1500–1700 °C | Temperature at which deformation occurs under loadISO 1893 |
| Outer Diameter | 100–800 mm | Must fit induction coil |
| Wall Thickness | 10–50 mm | Thicker for longer life but slower heating |
| Weight | 5–200 kg | Affects handling and furnace capacity |

Manufacturer profiles associated with Refractory Crucible.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
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, available materials include alumina (Al2O3), magnesia (MgO), zirconia (ZrO2), graphite, and silicon carbide (SiC). The choice depends on the melting temperature, chemical compatibility with the melt, and thermal shock requirements.
The directory lists a capacity range of 1 to 500 kg. The appropriate capacity depends on the melt size required for your application. Always confirm the exact capacity with the manufacturer.
Standards mentioned include ISO 28764 for thermal shock resistance, ISO 5017 for bulk density and apparent porosity, ISO 10059-1 for cold crushing strength, ISO 8894-1 for thermal conductivity, ISO 17562 for coefficient of thermal expansion, and ISO 1893 for refractoriness under load. These are verification references, not certifications.
Consider the melting temperature, the chemical nature of the material to be melted, the furnace coil dimensions, and the required capacity. Verify parameters such as maximum operating temperature, thermal shock resistance, and outer diameter to ensure a proper fit. Always consult the manufacturer for model-specific data.
