SOUTH AFRICA FOUNDRY GRADE CHROMITE SAND
♦Chromite Sand/foundry chrome ore, also known as chromite ore, is a special sand for foundry. It is a natural spinel dominated by chromite. After crushing, grinding and sieving, it is divided into prescribed grain size, and is suitable for sand for moulding (core-making).
♦Chrome Sand is mainly used in surface sand of large steel castings in casting production to prevent sand sticking on the surface of castings; secondly, its grinding powder is used in refractory aggregate of casting coatings; chromium ore sand is chilling material, which can replace part of chilled iron in moulding (core making).

Application
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.
