Details

High chromite stuffing sand is mainly made up of imported high pure chromite sand with reasonable particle size distribution, and suit for foundry industry and other refining process.

 

     Chromite sand ,it’s main chemical composition is Cr2O3(chromic oxide), 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 .
