Product Introduction
Fused ceramic foundry sand is an artificial spherical sand made by melting and cooling high-aluminum ore. It is suitable for cavity filling and high-temperature wear resistance in the casting process.
Product Features
High Refractoriness
Refractory ≥1800°C, capable of withstanding high-temperature molten metal.
Low Thermal Expansion
The thermal expansion coefficient is only 1/4 that of quartz sand, making it less susceptible to cracking and deformation during repeated heating and cooling.
Excellent Corrosion Resistance
Fused ceramic foundry sand exhibits excellent resistance to acids, alkalis, and other media.

FAQs
Q: What are the storage requirements for fused ceramic foundry sand?
A: Fused ceramic foundry sand should be stored in a dry, well-ventilated environment to avoid moisture and contamination.
Q: What is the chemical stability of this foundry sand?
A: Fused ceramic foundry sand has excellent chemical stability and does not react with most molten metals.
Q: Does this type of ceramic foundry sand cause wear on equipment?
A: Fused ceramic foundry sand has rounded particles and causes less wear on equipment.
Q: What are the advantages of fused ceramic foundry sand compared to quartz sand?
A: Fused ceramic foundry sand has higher refractoriness, lower thermal expansion, and more rounded particles.
Q: Is this type of ceramic foundry sand easy to transport?
A: Its particles are hard and resistant to breakage, making it suitable for long-distance transportation. It is usually packaged in ton bags or small bags.
