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 .
Application:
The chromite sand is compatible with all chemical processes for molds and cores. Currently large amounts of chromite sand are used in the foundry industry for the manufacture of molds and cores.
Chromite Sand is applicable to all types of steels and very appropriate for parts of chrome, chrome-nickel, manganese steel.
