Application of Chromite sand in Casting Production

Chromite sand belongs to the category of special sand in modeling materials. Its main mineral composition is FeO·Cr203, density is 4.0~4.8g/cm3, Mohs hardness is 5.5~6, refractoriness is greater than 1900℃, chromite sand It has a good anti-alkaline slag effect and does not react chemically with iron oxide. Because the thermal conductivity of chromite sand is several times greater than that of silica sand
