South Africa Chrome Ore Sand For Foundry - China

Foundry chromite sand is a natural process product of chromite through the broken screen classification, chrome ore, its main chemical composition of cr2o3, this kind of sand has stable heating volume, high thermal conductivity, when in contact with the molten metal, not only has good resistance to basic slag, not only has good resistance to basic slag, not react with ferric oxide and other chemicals, and itself has the characteristic of the solid phase sintering, can prevent the infiltration of molten metal very well, avoid to touch sand defects, suitable for all kinds of stainless steel, alloy steel and carbon steel gradually shape the original sand core and coating.
