User Guide for Proper Crucible Use:

  • Storage: Keep the crucible in a dry area to prevent moisture damage.
  • Handling: Handle the crucible with care to prevent cracks or damage.
  • Preheating: Gradually heat the crucible to 500°C to ensure proper drying before use.
  • Installation: Place the crucible at the center of the furnace, ensuring it's not in direct contact with the furnace walls to avoid uneven heating.

Best Practices for Crucible Installation and Operation:

Before using your Brass Melting Crucible, inspect it for any damage and ensure it is positioned correctly within the furnace. It is important to rotate the crucible weekly and monitor for signs of wear. Regular maintenance, including checking for cracks and preventing direct exposure to high flames, will significantly extend the service life of your crucible.

FAQS

Q1: What are the advantages of silicon carbide graphite crucibles compared to traditional graphite crucibles?

✅ Higher Temperature Resistance: Can withstand 1800°C long-term and 2200°C short-term (vs. ≤1600°C for graphite).
✅ Longer Lifespan: 5x better thermal shock resistance, 3-5x longer average service life.
✅ Zero Contamination: No carbon penetration, ensuring molten metal purity.

Q2: Which metals can be melted in these crucibles?
▸ Common Metals: Aluminum, copper, zinc, gold, silver, etc.
▸ Reactive Metals: Lithium, sodium, calcium (requires Si₃N₄ coating).
▸ Refractory Metals: Tungsten, molybdenum, titanium (requires vacuum/inert gas).

Q3: Do new crucibles require pre-treatment before use?
Mandatory Baking: Slowly heat to 300°C → hold for 2 hours (removes residual moisture).
First Melt Recommendation: Melt a batch of scrap material first (forms a protective layer).

Q4: How to prevent crucible cracking?

Never charge cold material into a hot crucible (max ΔT < 400°C).

Cooling rate after melting < 200°C/hour.

Use dedicated crucible tongs (avoid mechanical impact).

Q5: How to prevent crucible cracking?

Never charge cold material into a hot crucible (max ΔT < 400°C).

Cooling rate after melting < 200°C/hour.

Use dedicated crucible tongs (avoid mechanical impact).

Q6: What is the minimum order quantity (MOQ)?

Standard Models: 1 piece (samples available).

Custom Designs: 10 pieces (CAD drawings required).

Q7: What is the lead time?
⏳ In-Stock Items: Ships within 48 hours.
⏳ Custom Orders: 15-25 days for production and 20 days for mould.

Q8: How to determine if a crucible has failed?

Cracks > 5mm on inner wall.

Metal penetration depth > 2mm.

Deformation > 3% (measure outer diameter change).

Q9: Do you provide melting process guidance?

Heating curves for different metals.

Inert gas flow rate calculator.
