Chromite ore, also known as chromite ore, is a special sand for casting, is a natural spinel based on chromite, after crushing, grinding, screening into a specified size, suitable for molding (core) sand.
1. with excellent chilling characteristics, this characteristic does not reduce the thermal cracking, but can affect the temperature gradient, promote directional solidification without the use of cold iron. 2. Chromite is inert and does not react with other metal oxides. It is not wetted by manganese steel water. Chromite can be successfully used in manganese steel castings. 3. Linear expansion is small, and linear expansion is a factor that may cause sand inclusion in castings, so it may be used to mix wet sand mold for large castings.

In the industrial application, chromite belongs to the spinel, general chemical formula is FeOr2O3. With heat resistance and corrosion resistance and other properties In the metallurgical industry, chrome ore is mainly used for smelting ferrochrome and chromite metal.Chromite is the important iron-resistance minerals, it has a strong metal slag erosion resistance. Chromite not only have low thermal expansion rate,also have thermal shock resistance, and the chilling resistance is better than zircon. So Applied in brake pads, chromite can adjust the temperature coefficient of friction and reduce the heat recession, increase the efficiency of the brake,and it has the irreplaceable effect.
