Description of Foundry sand
Foundry sand is a kind of refractory particle with diameter of 0.053-2.0mm.
Mainly made of Al2O3·SiO2. It is ball-shaped particle made from bauxite
by high-temperature melting in electric-arc furnace, spraying and cooling.
Application of Foundry sand:
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.
Advantage of Ceramic foundry sand:
1, Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin leve
2, Smooth surface of spherical shape greatly improves collapsibility after pouring
3, Very low thermal expansion ensures fewer or no casting defects such as veining and deformation
4, Excellent thermal conductivity and heat absorption capacity close to that of Zircon
5, Superior refractory equivalent to Zircon and Chromites
