Chrome ore properties
Chromite sand for foundry is the product of natural chromite ore processed by crushing and screening processes. The main chemical composition of chromite sand is cr2o3. This kind of sand has stable volume when heated and high thermal conductivity. Good resistance to alkaline slag, no chemical reaction with iron oxide, etc., and it has the characteristics of solid phase sintering, which can well prevent the penetration of molten metal and avoid sand staining defects. It is suitable for various stainless steels and alloys Steel and carbon steel gradually mold the raw sand and paint for core making.
Application of chromite sand
It is suitable for drainage sand raw material, casting, ceramics, glass and refractory materials, etc. Applicable types of chromite sand: special for foundry grade, special for metallurgical grade. Chromium ore is mainly used for surface sand of large steel castings in foundry production to prevent sand sticking on the surface of castings; secondly, its grinding powder is used as refractory aggregate for casting coatings. Chromium ore is a chilling material. It can replace part of the cold iron when used. Chromite sand is suitable for foundry coatings, refractory materials, automobile brake pads, high-performance ceramic materials, ceramic and glass colorants, friction materials, chemical and metallurgical casting and other fields.
