Chromite Sand Applications in the Foundry Industry
Chromite sand is widely used in the foundry industry due to its excellent thermal stability, high melting point, and good resistance to metal penetration. Key applications include:
-
Mold and Core Making – Used in sand molds and cores to withstand high temperatures, particularly in steel and iron casting.
-
Anti-Burning Additive – Prevents burn-on defects by reducing sand-metal reactions.
-
Chill Application – Acts as an external chill to control solidification rates in heavy castings.
-
Facing Sand – Applied as a facing layer to improve surface finish and reduce veining defects.
-
Non-Ferrous Casting – Suitable for aluminum and copper alloys to minimize thermal expansion issues.
Its low thermal expansion and high heat conductivity make chromite sand a preferred choice for precision casting applications.
