High Refreactoriness ceramsite foundry sand
Ceramsite Foundry Sand
Ceramsite Foundry Sand, also called as NFS CERAMSITE-Nice Foundry Sand, is kind of man-made spherical shape ceramic particles featured by high refractoriness, low thermal expansion made by spraying melted from the fused bauxite. Ceramsite 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. And it is also good substitution to Chromite sand and Zircon sand because of its lower price. At the present, Ceramsite Foundry Sand is acknowledged in the worldwide as the newest and the best ideal sand for the foundries and Ceramsite Foundry Sand has a very wide feasibility of applications for the future development.
Product Description
The fused ceramic sand for foundry, known as "fused ceramic sand for foundry", is calcined bauxite with Al2O3 as the main component, which is prepared into foundry sand of different granularity through melting, spraying and sifting.
The particle size of the foundry pearl sand is generally between 0.053~3.53 mm, and its mineral composition is mainly corundum and mullite, with a trace of amorphous phase. The main chemical composition is Al203 and Si02, refractoriness generally ≥1800 ℃, is a kind of approximately spherical, high strength, high hardness of aluminum-silicon refractory materials.
The pearl sand is mostly black and brown. Baozhu sand has excellent physical and chemical properties so that it has been rapidly promoted in the casting production. In the past 20 years, foundry manufacturers have achieved significant economic and environmental benefits, and it is called by experts as "the new green casting material of the 21st century".
REFMAT has been in producing and supplying Ceramsite Foundry Sand for international market for more than 8 years and has abundant experience in this field. Our main market is in Korea, ASEAN countries, Middle East, US and enjoy very nice feedback from our customers due to our fast shipment, quality control, warmful service and profession.

Ceramsite sand
1, Product Introduction
Ceramsiteis a kind of refractory particle with diameter of 0.020mm~2.00mm, mainly made of Al2O3·SiO2. It is ball-shaped
particle made from fine bauxite ,which is fused in high-temperature electric-arc furnace and sprayed to ball shape.
2, Features of Ceramsite
- Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin level
- Smooth surface of spherical shape greatly improves collapsibility after pouring
- Low gas evolution and high permeability ensures fewer or no defects
- High refractoriness and little thermal expansion ensures no burn-on and deformation
- Artificial sand ensures stable chemical and physical properties
- Almost neutral PH value allows both acid and basic binder.
- High durability ensures high reusability.
-
3, Applications of Ceramsite
- Used in all types of foundry technique like resin-bonded sand, sodium silicate sand, and clay-bonded sand.
- As core sand for making like jacket core, oil duct core and tappet core of engine.
- Excellent replacement of chromite sand
- As dry sand of sand box for EPC process and V method of casting process.
- Application
Zircon Sand is used for refractory materials (called zirconium refractories, such as zirconium corundum bricks, zirconium refractory fibers), foundry sand for casting (precision casting sand), precision enamelware, and also for glass and metal (sponge) Zirconium) and zirconium compounds (zirconium dioxide, zirconium oxychloride, sodium zirconate, potassium fluorozirconate, zirconium sulfate, etc.) are produced.
Packaging & Shipping - 2. Iron and steel melting, cement rotary kiln and glass furnace, as the ideal material for manufacturing cast sliding plate, nozzle bricks, ladle bricks and open hearth furnace bricks, as well as the basic material for ecotone bricks of large cement kilns, medium cement kilns, refractory castable materials, and first-class and medium-class kiln furniture
