SAND

chromite sand for ladle nozzle filling

Chromite sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.

MAIN APPLICATION OF CHROMITE SAND

Chromite Sand in the foundry industry

Its 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. Its basicity 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 in the steel industry

In steel production, Chromite Sand is used as well filler for protection of the sliding gate in large steel holding ladles.

Chromite Sand in the glass industry

When ground to a fine flour, Chromite Sand is used for the production of green glass beverage containers.
