Characteristics of South African Casting Chrome Ore:

1. It has excellent chilling characteristics, which does not reduce thermal cracking, but can affect the temperature gradient and promote directional solidification without the need for cold iron.

2. Chromite sand is inert, so it does not react with other metal oxides. It is not wetted by manganese steel. Chromite sand can be successfully used in manganese steel castings. If the mold is painted normally and If the silicon oxide content is low, there is no iron olivine reaction.

3. Linear expansion is small, and linear expansion is a factor that may cause sand inclusion in castings, so it may be used to mix green sand molds for large castings.
