Chrome ore powder 325 mesh chromite sand powder price
Chromite is a naturally occurring spinel composed primarily of chromium and iron oxides. It is a by-product of ferrochrome production and is used primarily in foundry applications and glass production.
It is used as a highly fireproof sharpener for molds and cores. Native to South Africa. Sand is produced by crushing chromium ore and washing it in a spiral concentrator, followed by drying, dust removal, screening and particle size sorting.

Characteristics of chromite sand:
Chromite sand is a product made from natural chromite ore through crushing and screening. The main chemical component of chromium ore is cr2o3. This kind of sand has stable calorific value and high thermal conductivity. When in contact with molten metal, it not only has good resistance to alkaline slag and does not react with iron oxide, but also has the characteristics of solid-phase sintering, which can prevent the penetration of molten metal and avoid sanding defects. It is suitable for Various stainless steel, alloy steel and carbon steel are gradually formed with raw sand and paint as the core.
application
Chromite sands in the foundry industry
- Its properties allow the material to be used as cores and molding sand in high-strength gray iron and steel foundries.
- Its high thermal conductivity gives it good cooling properties, and its low thermal expansion gives it good dimensional stability.
- Its alkalinity is close to neutral, it can be used with a variety of resin bonding systems and inorganic binders, and it has high refractoriness and wide screening distribution.
- Chromite sands in the steel industry
- In steel production, chromite sand is also used as filler to protect sliding nozzles in large ladles.
- Chromite sands in the glass industry
- When ground into a fine powder, chromite sand can be used to produce green glass beverage containers.
