Use of chrome ores
- Chromite ore is suitable for drainage sand raw materials, casting, ceramics, glass and refractory materials.
- Applicable types of chromite ore: casting grade, metallurgical grade.
- Chromite ore is mainly used for the face sand of large steel castings in casting production to prevent sand sticking on the surface of castings;
- Its grinding powder is used for the refractory aggregate of casting coatings, and chromium ore is a quenched material, which can replace part of the cold iron when molding (core making).
- Chromite ore is suitable for casting coatings, refractory materials, automobile brake pads, high-performance ceramic materials
Ceramics and glass colorants, friction materials, chemical industry and metallurgical casting and other fields.
