2050 High refractoriness AFS50 ceramic foundry sand
Fused ceramsite used for heavy castings called foundry sand,ceramic sand, ceramic foundry sand,China Cerabeads,ceramsite sand and cerasand too, is made from high quality bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc

1.Widely used in foundry technique like resin-bonded sand, sodium silicate sand, and clay- bonded sand for sand core and casting mould making
2.Replace chromite sand and widely used in sand core making like jacket core, oil duct core, tappet core of engine.
3.Replace chromite sand for steel casting facing sand and sub-layer of molding sand (backing sand).
4.Widely used as dry sand and sand box for EPC process and V method of casting processes.
5.Widely used as the main raw materials of advanced refractory products (Ladle drainage sand,gravity casting material, casting coating, etc.).
6.Widely used as cleaning sand for copper and aluminum alloy castings
