Chrome ORE concentrate sand , Originally from South Africa (SAMANCOR),is a special kind of sand for casting , chromite sand is a natural spinel mainly composed of chromite ,
Chrome concentrate sand used as a highly fireproof sharpener for moulds and cores.
Chrome ore sand,It’s main chemical composition is Cr2O3, This kind of sand heating volume is stable , High thermal conductivity , sand molten metal contact , not only has a good alkali slag resistance , not with iron oxide and other chemical reaction , and itself has the characteristics of solid phase sintering , can well prevent the penetration of molten metal , avoid sand defects .
