46% Cr2O3 chromite sand price for foundry industrial
Detail Description
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 .
