Ceramic sand AFS30 for Steel casting

Ceramic sand AFS30 for Steel casting is fused ceramic sand with high refractoriness. In the meantime, of its spherical shape, ceramic sand could recycle used up to 10 times. Instead of silica sand in traditional lost foam casting(green sand casting), ceramic is cost-effective sand that is also environment friendly and better for the operator’s health.

  • Product Feature of Ceramic sand AFS30 for Steel casting
  1.  Good flowability and low angularity coefficient because of the ball shape of ceramic sand. When working with the core shooter, the sand is easy to go to small corners. Thus, it will get a smoother casting surface.
  2. The strength of ceramic sand is much higher than silica sand. It will increase work-life for casting.
  3. Low humidity. Ceramic sand is a type of dry sand because it is getting from fused bauxite without a washing process.
  4. Ceramic sand is easy to clean up after use and has good anti-sticky sand performance.
  5. High thermal conductivity and good air permeability.
  6. Low thermal expansion. That reduces casting cracks caused by sand expansion.
  7. Ceramic sand for casting is dustless
  • Applications of Ceramic sand AFS30 for Steel casting

  • FAQ:

Q: Are you a manufacturer?

A: Yes, Our factory was founded in 1999. We are an experienced manufacturer of foundry ceramic sand.

Q: What are the key quality indexes of ceramic foundry sand?

A: First of all, the Al2O3 content. We have three grade:75% Al2O3 ceramic sand,73% Al2O3 ceramic sand,70 Al2O3 ceramic sand.

Secondly, the particle size distribution of ceramic sand. We will provide samples according to the customer’s requirements. And make the same particle percentage coincide with confirmed sand.

Q: Where is the nearest port to your factory?

A: Qingdao and Tianjin are both near to us.

Q: What is the HS code of ceramic sand?

A: Since there is no specific HS code for ceramic sand, there are HS codes 69149000 and 68159990 suitable for exporting ceramic sand. But with our experience, HS code 68159990 is easier to do custom clearance with no risk to be inspected.

Q: How do you operate the QC system?

A: Before shipment, we will take 1 day to check the chemical composition for every bag. Our QC staff will take another day to check particle size distribution for every bag. We will reserve samples from each batch production in case there is anything wrong.

Q: What is the lead time for each order?

A: It depends on the quantity and sand size required. Generally 5-10 days for FCL(20-25MT).
