Chrome ore
Chromite sand is a special sand for foundry. It is a natural spinel mainly composed of chromite. After crushing, grinding, and screening, it is divided into specified particle sizes, which is suitable for molding (core making) sand. Chromium ore can be divided into primary Cr2O3 (>45%) and secondary Cr2O3 (>35%) according to chemical composition.
feature:
1. Heating volume stability
2. High thermal conductivity
3. Strong alkali resistance
4. Solid phase sintering, non-sticky sand
Advantages of chromite sand
Compared with silica sand, chromite sand can avoid most of the sand sticking to the casting, so it can also save the cost of surface preparation. Additionally, chromite can be recycled multiple times for use in different technologies.
