Ceramsite - A New Artificial Foundry Sand, Substitute For Chromite Sand

Product Description

Ceramsite

It is a new artificial foundry sand. With much more better comprehensive property and price comparation, it is now regarded as the right substitute for chromite sand and zircon sand. It is well regarded a revolution for new foundry sand.

Chemical compositions and physical properties:
Al2O3 78-85%
SiO2 8-12%
Fe2O3 <= 5%
TiO2 <= 3.5%
Refractoriness <= 1850 degrees centigrade
Angle factor <= 1.1
Thermal expansion(at 100 deg C) 0.15
Thermal conductivity 0.196 w/m.k
Specific heat 873 J/kg.
Bulk density 1.9-2.2 g/cm3
Particle sizes: AFS20, 30, 40, 50, 60, 70, 80, 100, 125, 140, 200, or 0.3-0.7mm, 0.4-0.9mm, 0.9-0.125mm, 1-2mm, 2-3mm, 325meesh, etc..

We summarize its all features namely advantages are as follows:

1. Round solid ball shape;
2. High refractoriness and service temperature;
3. Good air permeability and excellent dispersibility;
4. Lower thermal expansion rate and thermal conductivity;
5. Lower bulk density, lower true specific gravity and lower specific surface area;
6. Standard particle sizes;
7. Easily reclaimed by dry method;
8. Lower breakage rate during dry crushing;
9. Single application, no need mix with other sands;
10. To reduce pollution and protect environment.
Our conclusion (key words): easily use, save foundry sand, save binder, protect environment, improve casting quality, cost effective, best subsititute for other foundry sands.
