1.Product description-ceramic foundry sand
1.1Product brief introduction
1.1.1What’s ceramic foundry sand?
ceramic foundry sand is a kind of man-made spherical shape ceramic particles, also called as NFS ceramic foundry sand-Nice Foundry Sand,have an mean diameter in 0.053mm-3mm.
1.1.2How ceramic foundry sand made?
ceramic foundry sand was made by raw bauxite ore(Al2O3 45~90%),melting in the electric arc furnace,under the high temperature produced by the arc of the arc discharge, the raw material bauxite melting into liquid, the liquid flows out of the furnace, impose its 70 ~ 85m / s to air pressure, the liquid material with the strong wind crushing, cooled to spherical or nearly spherical shape ball, have smooth surface,the ceramsite sand ball is solid.
1.1.3What’s ceramiste sand mean for foundry industry?
ceramic foundry sand is also good substitution to Chromite sand and Zircon sand because of its lower price.At the present, ceramic foundry sand is acknowledged in the worldwide as the newest and the best ideal sand for the foundries and has a very wide feasibility of applications for the future development.
ceramic foundry sand provides a simple and efficient way in the foundry industry to improving the quality of the castings, reducing the production cost and avoiding environmental pollution so it is much better than silica sand.

1.4 Advantage of ceramiste sand
Perfect round ball shape
Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin use level
Smooth surface of spherical shape greatly improves collapsibility after pouring
High refractoriness
Superior refractory equivalent to zircon and Chromites
Higher than silicon sand, can be used for casting various materials.
Non-stick, non-sintering on the casting, which reduces the deformation of the casting.
Low coefficient of thermal expansion
Can be comparable to the zircon sand.
Ensures fewer or no casting defects such as veining and deformation.
Low gas evolution and high permeability
Can reduce defects, increase overall yield of casting and lower the cost of casting materials.
Low bulk density
The bulk density is 1.79-1.87/cm3, lower than the chromite sand of 2.5-2.9/cm3.The sand core is easy to move with light weight, and also can reduce the usage amount of sand.
1.5 Application of ceramsite sand
ceramic foundry sand is widely used in foundry technique like resin-bonded sand, sodium silicate sand, and clay- bonded sand for sand core and casting mould making.
ceramic foundry sand replace chromite sand and widely used in sand core making like jacket core, oil duct core, tappet core of engine.
ceramic foundry sand
replace chromite sand for steel casting facing sand and sub-layer of molding sand (backing sand).
ceramic foundry sand is widely used as dry sand and sand box for EPC process and V method of casting processes.
ceramic foundry sand is widely used as the main raw materials of advanced refractory products (Ladle drainage sand,gravity casting material, casting coating, etc.).
Ceramsite sand is widely used as cleaning sand for copper and aluminum alloy castings.
