Production of Foundry Sand for Casting

As a new, green sand, foundry sand has attracted much attention since its appearance and solved many problems in the field of casting, the applications of ceramic sand has been rapidly extended for its development and marketing in foundry industry. Ceramic sand has excellent properties, such as near spherical shape, higher refractoriness, good strength, and inert chemical characteristics.

The advantages of Foundry Sand for Casting

1. The thermal expansion coefficient is small, and its performance is comparable to zircon sand. When the sand is prepared with zircon sand, the casting will not produce expansion defects.

2. The sand is spherical, with good fluidity, easy to be rammed and good air permeability.

3. The surface is smooth and the structure is compact, so that the binder can cover evenly.

Q3: What are the advantages of ceramsite(foundry sand)?

A: High thermal conductivity, good stability, no cracking

Q4: What are the applications of Ceramsite(foundry sand)?

A: Ceramsite(foundry sand) has the advantages of high refractoriness, good fluidity and high air permeability, which to a certain extent solves the defects in foundry production( casting cost, defective rate and quality)

Q5: Do you know ceramsite(foundry sand)?

A: Ceramsite (foundry sand) can be used in resin sand (furan resin, phenolic resin), water glass sand (organic grease, CO2 hardening) and coated sand. Suitable for all kinds of metal castings: carbon steel, alloy steel (high manganese steel, high chromium cast iron), cast iron, cast copper, etc.

Q6: How many processes are needed for the finished product of Ceramsite(foundry sand)?

A: Bauxite - simple crushing - electric melting - wind crushing into ball - ball making - Screening - mixing – Ceramsite (foundry sand)

Q7: What the ceramsite(foundry sand) become more and more popular?

A: High fire resistance, easy to collapse. The mullite phase of ceramsite(foundry sand) is much higher than that of sintered product.
