    What is chromite sand used for?

    Chromite Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron.

    main applications of chromite sand

    Zhengzhou haixu abrasives co.,ltd,founded in 1999 from China,has been manufacturing and exporting abrasives for more than 20 years,including chromite sand,fused alumina and silicon carbide.

    About Chromite sand,we started it from 2017,and built factories in Lianyungang port then,but recently,we move and rebuilt 3 new factories of chromite sand in Tianjin port China.

    We import chomite sand from South Africa,then wash,dry,sieve,test,pack in China port,then re-export all over the world.

    What is the chromite sand used for:

    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.
