The main chemical composition of chromite sand is cr2o3, which has the characteristics of stable volume and high thermal conductivity when the sand is heated. In contact with molten metal, it not only has good alkali resistance to alkaline slag, but also does not contact with chemical substances such as iron oxide. It has the characteristics of solid phase sintering, which can prevent the infiltration of molten metal and avoid the defects of sand hitting. It is suitable for all kinds of stainless steel, alloy steel and carbon steel to gradually form the original sand core and coating.
