Chromite ore sand used in chemical , refractory and foundry factory
Chrome ore sand ,Its 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 , suitable for all
kinds of stainless steel , Alloy steel and carbon steel gradually modeling core
sand and paint .
