Casting chromite ore is natural chromite by crushing and screening and other processing products, the main chemical composition of chromium ore is CR2O3, this sand is heated volume is stable, high thermal conductivity, and molten metal contact, not only has a good resistance to alkaline slag, does not react chemically with iron oxide, etc., but also has the characteristics of solid phase sintering, can well prevent the penetration of molten metal, avoid sand defects, suitable for a variety of stainless steel, alloy steel and carbon steel gradually shape the core of raw sand and coatings.
Use of chromite ore
Suitable for drainage sand raw materials, casting, ceramics, glass and refractory materials. Applicable types of chromite ore: casting grade special, metallurgical grade special. Chrome ore is mainly used in casting production for the face sand of large steel castings to prevent sand sticking on the surface of castings; Secondly, its grinding powder is used for refractory aggregates for casting coatings, and chromium ore is a quenching material, which can replace part of the cold iron in molding (core making). Chromite ore is suitable for foundry coatings, refractories, automotive brake pads, high-performance ceramic materials, ceramic and glass colorants, friction materials, chemical industry and metallurgical casting and other fields.
