Chromite sand , Is a special kind of sand for casting , It is a natural spinel mainly composed of chromite ,It is crushed , ground and screened into specified grain size , which is suitable for molding (core-making ) sand

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 .
