South Africa Chrome Ore 46%min Chromite Sand AFS40-45 AFS45-50

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.
It is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa. The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.

CHARACTERISTICS

Characteristics of chromite sand:

Chromite sand is a product processed by natural chromite ore through crushing and sieving. The main chemical composition of chrome ore is cr2o3. This kind of sand has a stable heating volume and high thermal conductivity. When in contact with molten metal, not only Very good resistance to alkaline slag, does not react with iron oxide, etc., and itself has the characteristics of solid phase sintering, can prevent the penetration of molten metal, avoid sanding defects, suitable for a variety of stainless steel, alloy Steel and carbon steel are gradually shaping raw sand and coatings for the core.

APPLICATION

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.
