The main chemical composition ofchromite sandis cr2o3, which has the characteristics of stable volume and high thermal conductivity when the sand is heated.Contact with the molten metal, it not only has good resistance to basic slag, not with ferric oxide and other chemical reactions, and itself has the characteristics of the solid phase sintering, this can be a very good prevent the infiltration of molten metal, 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
