THE ADVANTAGE OF CHROMITE SAND

Comparing with silica sand，chromite sand can avoid most sand stick on the casting，therefor it can also save cost to make surface treatment. Moreover，chromite can be recycle used for several times upon to different technology.

Over all the chromite ore in the world， the one from South Africa are of the best quality level.So HAIXU Abrasive import original chromite ore from there and refine it to better purity to 46% Cr2O3.

THE APPLICATION

Chromite sand‘s’ properties enable the material to be used in high duty grey iron and steel foundries as core and mould making sand. Its high thermal conductivity gives it good chilling properties, low thermal expansion gives rise to good dimensional stability. Itsbasicity being close to neutral allows the use of a wide range of resin bonding systems and inorganic binders, it has a high refractoriness and a broad sieve distribution.

Chromite sand is suitable for steel casting including foundry such as：

Green Sand molding；

Shell molding；

Pep-Set system；

Furan Resin and Alkaline-phenolic Resin；

Core moulding

Lost foam casting

How to Choose grit size？

Generally，the smaller casting need to make, the finer grit size foundry adopted.The following frame shows it for reference:
