Chromite Sand Foundry Application:
- Chrome ore in casting production is mainly used for large steel surface sand, prevent casting surface adhering sand;
- Secondly, the grinding powder for the refractory aggregate of foundry coating, chrome ore is chilling material, when modeling (core) alternative part cold iron.
- Chromite sand for casting coating, refractory materials, brake pads, high-performance ceramic materials, ceramic and glass colorant, friction material, chemical, and metallurgical casting, etc.
