Ceramic Foundry sand

Ceramic 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.

Size: AFS25-35; AFS25-30; AFS30-35; AFS35-40; AFS40-45; AFS45-50; AFS40-50; AFS50-55; AFS55-60; AFS60-65.

 Main Advantage

1

Stabe quality on the chemical composition

2

Perfect grain round shape and various grain sizes

3

High gas permeability

4

High temperature resistance

5

Good break down and fast curing and good release

6

Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin level

7

Smooth surface of spherical shape greatly improves collapsibility after pouring

8

Very low thermal expansion ensures fewer or no casting defects such as veining and deformation

9

Excellent thermal conductivity and heat absorption capacity close to that of Zircon

10

Superior refractory equivalent to Zircon and Chromites 

Application

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