Ceramic Foundry Sand
Refratory Engineers (REI) offers a unique Foundry Sand by the name of SuperSand. SuperSand is a ceramic sand. SuperSand is a spherically shaped bauxite sand manufactured by melting bauxite in an Electric Arc Furnace followed by a proprietary spraying process. SuperSand beaded foundry sand (somestime called ceramic casting sand or ceramsite sand) provides a unique combination of spherical shape grain, chemistry, and physical properties that result in numerous performance advantages compared with Silica Sand, Chromite Sand, or Zircon Sand.
ADVANTAGES OF SUPERSAND
- SAFE Alternative for the environment, when compared with silica (silicosis) and zircon sand. SuperSand is silica-free, meaning it does not pose the same risk of silicosis to workers as traditional silica sands.
- SuperSand offers longer work life and reduction of sand usage.
- SuperSand’s spherical shape compared with angular shaped grains allows for easier separation from cast parts and improved collapsibility, resulting in lower scrap and casting efficiency. Its excellent flowability and permeability make it easier to fill complex molds and cores with intricate details.
- High Thermal Stability - SuperSand has high refractoriness, withstanding temperatures up to 1825°C, and very low thermal expansion. This significantly reduces casting defects like veining and scabbing.
- Lower Thermal expansion and Thermal Conductivity. Casting dimensions are more accurate and lower conductivity provides better mold performance.
- Requires 40-50% less resin to achieve the same mold strength, because the beads have a lower specific surface area than angular sand.
- Can be used as a single sand
- Offers lower true specific gravity and specific surface area
- Superior Durability - Because it has greater crush resistance than silica sand, it achieves a high reclamation rate (frequently 98-99% recovery), which in turn minimizes waste and reduces your sand consumption over time.
